Earth's Climate System Is Ridiculously Complex – With Draft Link Tutorial

By WUWT regular “Just The Facts”

I am often amused by claims that we understand Earth’s climate system, are able to accurately measure its behavior, eliminate all potential variables except CO2 as the primary driver of Earth’s temperature and make predictions of Earth’s temperature decades into the future, all with a high degree of confidence. I have been studying Earth’s climate system for several years and have found it to be a ridiculously complex, continually evolving and sometimes chaotic beast. Furthermore, our understanding of Earth’s climate system is currently rudimentary at best, our measurement capabilities are limited and our historical record is laughably brief. To help demonstrate the complexity of Earth’s climate system I have been compiling a list of all of the variables potentially involved in Earth’s climate system. This is a work in progress so additions, recommendations, corrections, questions etc. are most welcome. Once I develop this further and polish it up a bit I plan to convert it into a new WUWT Reference Page.

UPDATED: This list has undergone significant revisions and improvements based upon crowdsourcing the input of an array of very intelligent and knowledgeable contributors below. Additionally, this list was posted in comments in WUWT a few times previously, receiving input from a number of other very intelligent and knowledgeable contributors. This thread, along with links to the precursor threads below, will thus serve as the bibliography for the forthcoming WUWT Potential Climatic Variables reference page (unless someone can up with a better name for it…:)

Tornadoes:

http://en.wikipedia.org/wiki/Tornado

and Polar Vortices;

http://en.wikipedia.org/wiki/Polar_vortex

which “are caused when an area of low pressure sits at the rotation pole of a planet. This causes air to spiral down from higher in the atmosphere, like water going down a drain.”

http://www.universetoday.com/973/what-venus-and-saturn-have-in-common/

Here’s an animation of the Arctic Polar Vortex in Winter 2008 – 09:

When a Polar Vortex breaks down it causes a Sudden Stratospheric Warming:

Earth’s Rotational Energy influences Plate Tectonics;

http://en.wikipedia.org/wiki/Plate_tectonics

“By analyzing the minute changes in travel times and wave shapes for each doublet, the researchers concluded that the Earth’s inner core is rotating faster than its surface by about 0.3-0.5 degrees per year.

That may not seem like much, but it’s very fast compared to the movement of the Earth’s crust, which generally slips around only a few centimeters per year compared to the mantle below, said Xiaodong Song, a geologist at the University of Illinois at Urbana-Champaign and an author on the study.

http://www.livescience.com/9313-earth-core-rotates-faster-surface-study-confirms.html

The surface movement is called plate tectonics. It involves the shifting of about a dozen major plates and is what causes most earthquakes”:

http://en.wikipedia.org/wiki/Earthquake

Volcanoes;

http://en.wikipedia.org/wiki/Volcano

and Mountain Formation;

http://en.wikipedia.org/wiki/Mountain_formation

which can influence the creation of Atmospheric Waves:

http://en.wikipedia.org/wiki/Atmospheric_wave

Lastly, Rotational Energy is the primary driver of Earth’s Dynamo;

http://en.wikipedia.org/wiki/Dynamo_theory

which generates Earth’s Magnetic Field;

http://en.wikipedia.org/wiki/Earth%27s_magnetic_field

and is primarily responsible for the Earthy behaviors of the Magnetosphere;

http://en.wikipedia.org/wiki/Magnetosphere

with certain secular variations in Earth’s magnetic field originating from ocean flow/circulation;

http://news.nationalgeographic.com/news/2009/06/090622-earths-core-dynamo.html

http://iopscience.iop.org/1367-2630/11/6/063015/fulltext

though Leif Svalgaard notes that these are minor variations, as the magnetic field originating from ocean flow/circulation “is 1000 times smaller than the main field generated in the core.”

http://wattsupwiththat.com/2011/06/30/earths-climate-system-is-ridiculously-complex-with-draft-link-tutorial/#comment-707971

Also of note, “Over millions of years, [Earth’s] rotation is significantly slowed by gravitational interactions with the Moon: see tidal acceleration.

http://en.wikipedia.org/wiki/Tidal_acceleration

“The presence of the moon (which has about 1/81 the mass of the Earth), is slowing Earth’s rotation and lengthening the day by about 2 ms every one hundred years.”

“However some large scale events, such as the 2004 Indian Ocean earthquake, have caused the rotation to speed up by around 3 microseconds.[21] Post-glacial rebound, ongoing since the last Ice age, is changing the distribution of the Earth’s mass thus affecting the Moment of Inertia of the Earth and, by the Conservation of Angular Momentum, the Earth’s rotation period.”

http://en.wikipedia.org/wiki/Earth%27s_rotation

2. Orbital Energy, Orbital Period, Elliptical Orbits (Eccentricity), Tilt (Obliquity) and Wobble (Axial precession):

creates Earth’s seasons;

http://en.wikipedia.org/wiki/Season

which drives annual changes in Arctic Sea Ice;

and Antarctic Sea Ice;

the freezing and melting of which helps to drive the Thermohaline Circulation;

http://en.wikipedia.org/wiki/Thermohaline_circulation

and can result in the formation of Polynyas:

http://en.wikipedia.org/wiki/Polynya

Earth’s orbit around the Sun, Earth’s tilt, Earth’s wobble and the Moon’s orbit around Earth, Earth’s Rotation, and the gravity of the Moon, Sun and Earth, act in concert to determine the constantly evolving Tidal Force on Earth:

http://en.wikipedia.org/wiki/Tidal_force

This Tidal Force is influenced by variations in Lunar Orbit;

Over longer time frames changes to Earth’s orbit, tilt and wobble called Milankovitch cycles;

http://en.wikipedia.org/wiki/Milankovitch_cycles

may be responsible for the periods of Glaciation (Ice Ages);

http://www.homepage.montana.edu/~geol445/hyperglac/time1/milankov.htm

that Earth has experienced for the last several million years of its climatic record:

http://en.wikipedia.org/wiki/Ice_age

Also of note, over very long time frames, “the Moon is spiraling away from Earth at an average rate of 3.8 cm per year”;

http://curious.astro.cornell.edu/question.php?number=124

3. Gravitation:

http://en.wikipedia.org/wiki/Gravitation

The gravity of the Moon, Sun and Earth, Earth’s rotation, Earth’s orbit around the Sun, Earth’s tilt, Earth’s wobble and the Moon’s orbit around Earth act in concert to determine the constantly evolving Tidal Force on Earth:

http://en.wikipedia.org/wiki/Tidal_force

can result in the formation of Polynyas:

http://en.wikipedia.org/wiki/Polynya

Gravity Waves;

http://en.wikipedia.org/wiki/Gravity_wave

which may be partially responsible for the Quasi-Biennial Oscillation (QBO);

http://en.wikipedia.org/wiki/Quasi-biennial_oscillation

“on an air–sea interface are called surface gravity waves or Surface Waves”;

http://en.wikipedia.org/wiki/Surface_wave

“while internal gravity waves are called Inertial Waves”:

http://en.wikipedia.org/wiki/Inertial_waves

“Rosby Waves;

http://en.wikipedia.org/wiki/Rossby_waves

Geostrophic Currents

http://en.wikipedia.org/wiki/Geostrophic

and Geostrophic Wind

http://en.wikipedia.org/wiki/Geostrophic_wind

are examples of inertial waves. Inertial waves are also likely to exist in the core of the Earth”

Earth’s gravity is the primary driver of Plate Tectonics;

http://en.wikipedia.org/wiki/Plate_tectonics

“The Slab Pull;

http://en.wikipedia.org/wiki/Slab_pull

force is a tectonic plate force due to subduction. Plate motion is partly driven by the weight of cold, dense plates sinking into the mantle at trenches. This force and the slab suction force account for most of the overall force acting on plate tectonics, and the Ridge Push;

http://en.wikipedia.org

force accounts for 5 to 10% of the overall force.”

Plate Tectonics drive “cycles of ocean basin growth and destruction, known as Wilson cycles;

http://csmres.jmu.edu/geollab/fichter/Wilson/Wilson.html

involving continental rifting;

http://en.wikipedia.org/wiki/Rift

seafloor-spreading;

http://en.wikipedia.org/wiki/Seafloor_spreading

subduction;

http://en.wikipedia.org/wiki/Subduction

and collision.”:

http://en.wikipedia.org/wiki/Continental_collision

“Climate change on ultra-long time scales (tens of millions of years) are more than likely connected to plate tectonics.”

“Through the course of a Wilson cycle continents collide and split apart, mountains are uplifted and eroded, and ocean basins open and close. The re-distribution and changing size and elevation of continental land masses may have caused climate change on long time scales”;

http://www.pbs.org/wgbh/nova/ice/chill.html

a process called the Supercontinent Cycle:

http://en.wikipedia.org/wiki/Supercontinent_cycle

Earth’s gravity is responsible for Katabatic Wind:

http://en.wikipedia.org/wiki/Katabatic_wind

4. Solar Energy;

http://en.wikipedia.org/wiki/Solar_energy

results is Solar Radiation/Sunlight;

http://en.wikipedia.org/wiki/Solar_radiation

which varies based upon 11 and 22 year cycles:

http://en.wikipedia.org/wiki/Solar_cycle

Total Solar Irradiance (TSI);

http://www.ngdc.noaa.gov/stp/solar/solarirrad.html

appears to fluctuate “by approximately 0.1% or about 1.3 Watts per square meter (W/m2) peak-to-trough during the 11-year sunspot cycle”:

http://en.wikipedia.org/wiki/Solar_variation

Solar Energy also drives the Hydrological/Water Cycle;

http://en.wikipedia.org/wiki/Hydrological_cycle

within the Hydrosphere;

http://en.wikipedia.org/wiki/Hydrosphere

as Total Solar Irradiance (TSI) causes evaporation;

http://en.wikipedia.org/wiki/Evaporation

that drives cloud formation;

http://en.wikipedia.org/wiki/Cloud

results in precipitation;

http://en.wikipedia.org/wiki/Precipitation_%28meteorology%29

that results in the Water Distribution on Earth;

http://en.wikipedia.org/wiki/Water_distribution_on_Earth

creates surface runoff;

http://en.wikipedia.org/wiki/Runoff_%28water%29

which result in rivers;

http://en.wikipedia.org/wiki/River

and drives erosion:

http://en.wikipedia.org/wiki/Erosion

Solar energy is also “The driving force behind atmospheric circulation is solar energy, which heats the atmosphere with different intensities at the equator, the middle latitudes, and the poles.”

Solar Ultraviolet (UV) radiation;

http://en.wikipedia.org/wiki/Ultraviolet

appears to vary by approximately 10% during the solar cycle;

http://www.nasa.gov/topics/solarsystem/features/solarcycle-sorce.html

has been hypothesized to influence Earth’s climate;

http://wattsupwiththat.com/2011/04/05/courtillot-on-the-solar-uv-climate-connection/

however Leif Svalgaard argues that,

This is well-trodden ground. Nothing new to add, just the same old, tired arguments. Perhaps a note on EUV: as you can see here (slide 13)

http://lasp.colorado.edu/sorce/news/2008ScienceMeeting/doc/Session1/S1_03_Kopp.pdf the energy in the EUV band [and other UV bands] is very tiny; many orders of magnitude less than what shines down on our heads each day. So a larger solar cycle variation of EUV does not make any significant difference in the energy budget.

Grand Minimum;

Leif Svalgaard says: February 6, 2011 at 8:26 pm

If L&P are correct and sunspots become effectively] invisible [not gone] it might mean another Grand Minimum lasting perhaps 50 years. During this time the solar cycle is still operating, cosmic rays are still modulated, and the solar wind is still buffeting the Earth.”

“It will lead to a cooling of a couple of tenths of a degree.”

5. Geothermal Energy;

http://en.wikipedia.org/wiki/Geothermal_energy

influences Earth’s climate especially when released by Volcanoes;

http://en.wikipedia.org/wiki/Volcano

“which are generally found where tectonic plates are diverging;

http://en.wikipedia.org/wiki/Divergent_boundary

or converging”;

http://en.wikipedia.org/wiki/Convergent_boundary

however, “intraplate volcanism has also been postulated to be caused by mantle plumes”:

http://en.wikipedia.org/wiki/Mantle_plume

“These so-called “hotspots”;

http://en.wikipedia.org/wiki/Hotspot_%28geology%29

for example Hawaii, are postulated to arise from upwelling diapirs;

http://en.wikipedia.org/wiki/Diapir

from the core-mantle boundary, 3,000 km deep in the Earth.”

Volcanoes have been shown to influence Earth’s climate;

http://www.geology.sdsu.edu/how_volcanoes_work/climate_effects.html

http://www.longrangeweather.com/global_temperatures.htm

including in the infamous Year Without a Summer;

http://en.wikipedia.org/wiki/Year_Without_a_Summer

which was partially caused by the 1815 eruption of Mount Tambora;

http://en.wikipedia.org/wiki/1815_eruption_of_Mount_Tambora

and is called a Volcanic Winter:

http://en.wikipedia.org/wiki/Volcanic_winter

“Volcanic Ash;

http://en.wikipedia.org/wiki/Volcanic_ash

particles have a maximum residence time in the troposphere of a few weeks.

The finest Tephera;

http://en.wikipedia.org/wiki/Tephra

remain in the stratosphere for only a few months, they have only minor climatic effects, and they can be spread around the world by high-altitude winds. This suspended material contributes to spectacular sunsets.

“The greatest volcanic impact upon the earth’s short term weather patterns is caused by sulfur dioxide gas;”

http://en.wikipedia.org/wiki/Sulfur_dioxide

“In the cold lower atmosphere, it is converted to Sulfuric Acid;

http://en.wikipedia.org/wiki/Sulfuric_acid

sulfuric acid by the sun’s rays reacting with stratospheric water vapor to form sulfuric acid aerosol layers. The aerosol remains in suspension long after solid ash particles have fallen to earth and forms a layer of sulfuric acid droplets between 15 to 25 kilometers up. Fine ash particles from an eruption column fall out too quickly to significantly cool the atmosphere over an extended period of time, no matter how large the eruption.

Sulfur aerosols last many years, and several historic eruptions show a good correlation of sulfur dioxide layers in the atmosphere with a decrease in average temperature decrease of subsequent years. The close correlation was first established after the 1963 eruption of Agung volcano in Indonesia when it was found that sulfur dioxide reached the stratosphere and stayed as a sulfuric acid aerosol.

Without replenishment, the sulfuric acid aerosol layer around the earth is gradually depleted, but it is renewed by each eruption rich in sulfur dioxide. This was confirmed by data collected after the eruptions of El Chichon, Mexico (1982) and Pinatubo, Philippines (1991), both of which were high-sulfur compound carriers like Agung, Indonesia.”

http://volcanology.geol.ucsb.edu/gas.htm

There is also some evidence that if “volcanic activity was high enough, then a water vapor anomaly would be introduced into the lower stratosphere before the anomaly due to the previous eruption had disappeared. The result would be threefold in the long term: stratospheric cooling, stratospheric humidification, and surface warming due to the positive radiative forcing associated with the water vapor.”

See: http://journals.ametsoc.org/doi/pdf/10.1175/1520-0442(2003)016%3C3525%3AAGSOVE%3E2.0.CO%3B2#h1

Geothermic Energy can also warm the atmosphere through Hot Springs;

http://en.wikipedia.org/wiki/Hot_springs

Or warm the ocean through Hydrothermal Vents:

Additional atmosphere components includes Water vapor (H2O) that represents approximately 0.40% over full atmosphere, typically 1%-4% at surface.

http://en.wikipedia.org/wiki/Water_vapor;

Aerosols;

http://en.wikipedia.org/wiki/Aerosol

that “act as cloud condensation nuclei, they alter albedo (both directly and indirectly via clouds) and hence Earth’s radiation budget, and they serve as catalysts of or sites for atmospheric chemistry reactions.”

“Aerosols play a critical role in the formation of clouds;

http://en.wikipedia.org/wiki/Clouds

Clouds form as parcels of air cool and the water vapor in them condenses, forming small liquid droplets of water. However, under normal circumstances, these droplets form only where there is some “disturbance” in the otherwise “pure” air. In general, aerosol particles provide this “disturbance”. The particles around which cloud droplets coalesce are called cloud condensation nuclei (CCN) or sometimes “cloud seeds”. Amazingly, in the absence of CCN, air containing water vapor needs to be “supersaturated” to a humidity of about 400% before droplets spontaneously form! So, in almost all circumstances, aerosols play a vital role in the formation of clouds.”

The major climate influence from volcanic eruptions is caused by gaseous sulfur compounds, chiefly Sulfur Dioxide;

http://en.wikipedia.org/wiki/Sulfur_dioxide

which reacts with OH and water in the stratosphere to create sulfate aerosols with a residence time of about 2–3 years.”

“Emission rates of [Sulfur Dioxide] SO2 from an active volcano range from 10 million tonnes/day according to the style of volcanic activity and type and volume of magma involved. For example, the large explosive eruption of Mount Pinatubo on 15 June 1991 expelled 3-5 km3 of dacite magma and injected about 20 million metric tons of SO2 into the stratosphere. The sulfur aerosols resulted in a 0.5-0.6°C cooling of the Earth’s surface in the Northern Hemisphere.”

http://volcanoes.usgs.gov/hazards/gas/index.php

“The 1815 eruption [of Mount Tambora] is rated 7 on the Volcanic Explosivity Index, the only such eruption since the Lake Taupo eruption in about 180 AD. With an estimated ejecta volume of 160 cubic kilometers, Tambora’s 1815 outburst was the largest volcanic eruption in recorded history.”

“The eruption created global climate anomalies that included the phenomenon known as “volcanic winter”;

http://en.wikipedia.org/wiki/Volcanic_winter

1816 became known as the “Year Without a Summer”;

http://en.wikipedia.org/wiki/Year_Without_a_Summer

because of the effect on North American and European weather. Agricultural crops failed and livestock died in much of the Northern Hemisphere, resulting in the worst famine of the 19th century.”

http://en.wikipedia.org/wiki/Mount_Tambora

“In the spring and summer of 1816, a persistent “dry fog” was observed in the northeastern US. The fog reddened and dimmed the sunlight, such that sunspots were visible to the naked eye. Neither wind nor rainfall dispersed the “fog”. It has been characterized as a stratospheric sulfate aerosol veil.”

“The greatest volcanic impact upon the earth’s short term weather patterns is caused by sulfur dioxide gas;”

http://en.wikipedia.org/wiki/Sulfur_dioxide

“In the cold lower atmosphere, it is converted to Sulfuric Acid;

http://en.wikipedia.org/wiki/Sulfuric_acid

sulfuric acid by the sun’s rays reacting with stratospheric water vapor to form sulfuric acid aerosol layers. The aerosol remains in suspension long after solid ash particles have fallen to earth and forms a layer of sulfuric acid droplets between 15 to 25 kilometers up. Fine ash particles from an eruption column fall out too quickly to significantly cool the atmosphere over an extended period of time, no matter how large the eruption.

Sulfur aerosols last many years, and several historic eruptions show a good correlation of sulfur dioxide layers in the atmosphere with a decrease in average temperature decrease of subsequent years. The close correlation was first established after the 1963 eruption of Agung volcano in Indonesia when it was found that sulfur dioxide reached the stratosphere and stayed as a sulfuric acid aerosol.

Without replenishment, the sulfuric acid aerosol layer around the earth is gradually depleted, but it is renewed by each eruption rich in sulfur dioxide. This was confirmed by data collected after the eruptions of El Chichon, Mexico (1982) and Pinatubo, Philippines (1991), both of which were high-sulfur compound carriers like Agung, Indonesia.”

http://volcanology.geol.ucsb.edu/gas.htm

There is also some evidence that if “volcanic activity was high enough, then a water vapor anomaly would be introduced into the lower stratosphere before the anomaly due to the previous eruption had disappeared. The result would be threefold in the long term: stratospheric cooling, stratospheric humidification, and surface warming due to the positive radiative forcing associated with the water vapor.”

9. Albedo

http://en.wikipedia.org/wiki/Albedo

“or reflection coefficient, is the diffuse reflectivity or reflecting power of a surface. It is defined as the ratio of reflected radiation from the surface to incident radiation upon it. Being a dimensionless fraction, it may also be expressed as a percentage, and is measured on a scale from zero for no reflecting power of a perfectly black surface, to 1 for perfect reflection of a white surface.”

Clouds

http://en.wikipedia.org/wiki/Clouds

Aerosols

http://en.wikipedia.org/wiki/Aerosol

“act as cloud condensation nuclei, they alter albedo (both directly and indirectly via clouds) and hence Earth’s radiation budget, and they serve as catalysts of or sites for atmospheric chemistry reactions.”

“Aerosols play a critical role in the formation of clouds. Clouds form as parcels of air cool and the water vapor in them condenses, forming small liquid droplets of water. However, under normal circumstances, these droplets form only where there is some “disturbance” in the otherwise “pure” air. In general, aerosol particles provide this “disturbance”. The particles around which cloud droplets coalesce are called cloud condensation nuclei (CCN) or sometimes “cloud seeds”. Amazingly, in the absence of CCN, air containing water vapor needs to be “supersaturated” to a humidity of about 400% before droplets spontaneously form! So, in almost all circumstances, aerosols play a vital role in the formation of clouds.”

Given that the 11 year cycle variation of about 1.3 Watts per square meter (W/m2) at the outer surface of Earth’s atmosphere isn’t sufficient to have a large influence on Earth’s temperature, it seem pointless to try to estimate and use the smaller and less precise number at surface level. What do you think?
We don’t even know the albedo well enough for this to matter. To first order, what reaches the surface will scale with what comes from the sun. Just do the calculation in percent and the problem goes away: dTSI/TSI =0.1% and dT/T = 0.1/4%. The 4 is from S-B law, not spherical Earth. So with dT/T = 0.025% of 288K we get dT = 0.072 K

> If CO2 perturbation decay time were short, CO2 concentrations would go down during a recession.
China is now the largest CO2 emitter by country. They didn’t have a recession, I don’t know if their growth rate slowed down.
One thing that was interesting at ICCC #6 is the disagreement about CO2 dwell time in the atmosphere. Alan Carlin didn’t talk about it, but I read his recent paper on the way down. His review of the literature left him convinced the dwell time is short. Some people at the ICCC said the dwell time is long.
Either way, I’m not too concerned. The key thing, CO2 feedback (plus H2O) appears greatly overstated. I talked to one scientist who expects to have a paper out soon adding to that theme.

The story that Galileo dropped a small and large cannonball from the Pisa belfry is probably fiction. But he did use a neat logical argument that all objects of different weights fall at the same speed. CO2 doesn’t fall any faster than N2.
The molecules of gas are moving at around 500m/s or about a THOUSAND miles an hour. There is no way with those velocities you will get gases stratifying out by weight within the first few miles of the atmosphere. If they did.. O2 heavier than N2, we would be walking in a few inches of CO2 and with our heads in pure oxygen!

Sigh. You’re imagining our real atmosphere to be an ‘ideal gas atmosphere’ – as if it’s empty space with molecules zipping around at great speeds through it, bouncing off each other and so ‘mixing thoroughly’, etc. . “Real” and ideal” are technical terms in physics when referring to gases. The ideal gas is an imaginary construct, no real gas is like an ideal gas nor does any real gas obey ideal gas law. You need to look up the difference, but you need to be vigilant, AGWScience takes bits of descriptions from physics and mixes and mismatches, takes out of context. You are giving an AGWScience description of our atmosphere because it says that nitrogen, oxygen and carbon dioxide are ideal gases, but they’re not, they are real. Real gases have volume, etc. Our atmosphere is not empty space with tiny hard dots with no volume travelling at these vast speeds through it bouncing off other molecules also travelling through empty space at these vast speeds..
How does sound travel in your world?
You’ll need to get to grips with volume and the rest. Now, I don’t know if the first of these links is written by someone who knows the difference and is being disingenuous or just repeating an AGWScience meme, much as you’ve given an AGWScience standard meme response about speed and stratification into layers, it doesn’t matter here, the important thing is to note where it has been done.

http://www.answers.com/topic/gas-laws “Five Postulates Regarding the Behavior of Gases …. Second, there is vitually no force attracting gas molecules to one another.”

That is a fib. It’s taken direct from ideal gas description, and doesn’t relate at all to real gases which have attractive force.
This is where, how, AGWScience has taken its description of gas molecules and pretends that this is a description of real gas molecules in our real world. That heading should include the word “Ideal”. As here:

http://hyperphysics.phy-astr.gsu.edu/hbase/kinetic/idegas.html
An ideal gas is defined as one in which all collisions between atoms or molecules are perfectly elastic and in which there are no intermolecular atractive forces. One can visualize it as a collection of perfectly hard spheres which collide but which otherwise do not interact with each other. In such a gas, all the internal energy is in the form of kinetic energy and any change in internal energy is accompanied by a change in temperature.

[The last sentence is where AGWScience refers back to in its emphasis on radiation as the means of heat transfer and avoids mention of convection which requires an understanding of real volume and why AGW supporters think that the only effect of electromagnetic waves is to create heat, so have great difficulty understanding that the “Solar” energies such as Visible can’t actually heat water, but think that because blue light penetrates further in the ocean it is heating the ocean.]
Anyway, although it appears the first piece is making a distinction between ideal and real gases, it isn’t, it is saying that this is a description of Gases, but this is a description of Ideal Gas. Which is purely imaginary and comes from the beginning of first exploration into such things. The article gives the appearance of being about real gases, but these AGW memes are slipped in so the difference is not obvious, but hidden, he is mixing and taking out of context.. Especially because he gives the history of the named originators he gives the appearance of covering the subject, but, he has missed one out.

http://www.tutorvista.com/content/chemistry/chemistry-iii/matter-states/ideal-and-real-gases.php
Ideal and Real Gases
An ideal gas is one, which obeys the general gas equation of PV=nRT and other gas laws at all temperatures and pressures. A real gas, does not obey the general gas equation and other gas laws at all conditions of temperature and pressure.
Causes for deviations
In order to know the causes for deviations from ideality, Van der Waal pointed out the faulty assumption that were made in formulating the kinetic molecular model of gases. etc.

Now, you have to bear in mind as I said earlier, that AGWScience does not have any internal consistency in its ‘science’, it cherry picks and is perfectly happy to use conflicting ideas as it is to use ideal gas properties for real gases by taking descriptions out of context as here in the first link and from which you get your picture of our atmosphere as empty space with all these molecules speeding through it at great speeds. Not all energy creates heat in interactions, the ideal gas laws are wrongly applied to the real world..
Our atmosphere is a real gaseous volume of Air, gases and liquids are fluids so what we have pressing down on us at around a ton per sq ft is a heavy fluid, not empty space. It is volumes of this fluid moving around which is the way heat is transferred through convection in our real atmosphere and which in turn gives us ‘wind’; when a volume of this fluid is heated and becoming less dense rises into colder volumes above it, the heavier denser volumes displace the lighter volumes, what we feel as wind. Wind is volumes of the gas Air on the move. These do not cross over from one hemisphere to the other, although there is some mixing at the equator, but follow basic circulation patterns within their own hemispheres.
One description I read to get the ‘feel’ of this our real atmosphere. Imagine standing at the bottom of a swimming pool with 10′ of water above you, now go out into the middle of a field – the atmosphere of the fluid gas Air above us is like that. A ton of it on our shoulders. “Half of the Earth’s atmosphere is squashed down into the first 3 miles above, 90% is squashed into the first 10 miles. Above 10 miles the air is so thin that the pressure is less than the best vacuums on the surface of the earth.” Sorry, missing source for that. It is not empty space.
That there is ’empty’ space between molecules means that gases can be compressed, the high and low pressures we feel in our atmosphere. If it were really empty space with volumeless molecules zipping through it we would have no sound. We have sound because the weight of that volume under gravity stops molecules from zipping through it. They may well be moving at great speeds, but they’re going nowhere fast.
Sound is passed through the fluid Air as waves are passed through the ocean, the Air doesn’t move as wind, but the energy from the sound causes the molecules of the volume Air to vibrate and knock into the molecules around it causing them to vibrate and that vibration is passed along through the air. When they stop vibrating they’re still where they started.
Now, within all that. Molecules of nitrogen and oxygen are practically the same weight, together the combination gas Air. Making up practically 100% of our atmosphere, dry weight, apart from water vapour the rest are trace gases. Water vapour is a gas, it is lighter than the gas air, it always rises in air, evaporation. So too, heavier gases sink in air. Carbon dioxide is one and a half times heavier than air, it sinks, displacing air.
Whether one molecule or a bunch of them together, heavier than air gases will sink and lighter than air gases will rise.
In mines methane is a hazard, it used to be tested for in a new mine by sending someone in covered in wet towels and carrying a lit candle on a long pole – because lighter than air methane pools at the ceilings. Careful if you’re invited to a pss-up in a brewery, that you don’t fall asleep on the floor next to open vats of beer brewing… Large amounts of carbon dioxide will displace the lighter oxygen and suffocate you. A hazard around active volcanoes venting, because it will gather in a layer in hollows, until dispersed by something acting on it to move it such as wind. It cannot diffuse into air of its own volition as if it were an ideal gas.

double sigh. The air is to a very high approximation an ideal gas. Even near the center of the sun where the density is ten times that of lead, the material is very nearly an ideal gas. Your ideas about this are as wrong as they can be. Amazing that there are people out there who can be so wrong while pretending to know anything at all.

You are right on this: Tambora, at 2 Pg doesn’t equate to current rates of about 31 Pg/yr. My argument is weak here.
The climate does not appear to be unstable, however that lack of evidence is not evidence of a lack of instability, I grant you. Tornadoes are probably a good example of chaos theory in action: a buildup with little happening, a sudden burst of terrific change and activity and a very sudden end. A hurricane seems less of an example, as the process is incremental and progressive, and once started drifts away rather than stops abruptly. Weather systems and the climate are even longer term. progressive and incremental things.
CO2 as CAGW is positioned as a keystone gas with sudden, large and unexpected temperature effects. Temperature events are certainly sudden and unexpected, but going up and down don’t seem to be well correlated with CO2 changes. I understand the if A then B, if B not necessarily A problem with CO2 and temperature changes. But so far the temperature changes are slow, incremental and progressive, and less than the worrisome levels by the IPCC. If CO2 is not a keystone gas with a Mandelbrot chaotic nature, then the CAGW worry is untenable.
The evidence so far is not observational, but modelling. If we could agree to that, then what would be left is the argument about how much the Precautionary Principle should be applied. But since the science is “settled” and the outcome “certain” we cannot do that. Yet that is the crux: does CO2 additions to the atmosphere at 2 ppmv/yr from 392 to 560 or more trigger some detrimental and radical temperature change? So far the evidence says “no”. When does this threshold event occur? The IPCC model says there is a multiplier effect, but so far we are not seeing anything out of the historical mode if a 60-year cyclicity is allowed.
I see that by 2015 the difference between the IPCC warmist theories and the skeptics will be large enough and the trends going in the opposite directions long enough to determine if one is broken or at least sufficiently weakened for the CAGW threat to go away or – perish the thought – be about to bite our butts.

“..(izen).Because the Earth is a rotating sphere each 1366W/m2 from the Sun is effectively spread over 4m2 of the Earths surface. Therefore the lower figure is 0.1% of the total solar energy per square meter of the Earths SURFACE.”
“Why is this even being discussed?”
———————
Because a poster (Michael Tobias) using the lower figure of solar energy per square meter of the Earth surface was accused of getting the figure wrong and failing to use ‘giggle’ or search engines to get the ‘right’ figure.
It was a classic example of Dunning-Kruger, ignorance resulting in the accusation that someone with more accurate knowledge is wrong because they do not match the pre-conceptions already held.

The evidence so far is observational. The measured rise in anthropogenic CO2. The measured absoprtion spectrum of CO2. The measured increase and spectal change in downwelling longwave radiation. The measured drop and spectral change in outgoing LW radiation.
And the measured rise in land and sea surface temperatures, the rise in sea level, the fall in glacier mass balance, the loss of polar sea ice, the increase in atmospheric water vapour, the decrease in snow cover and the various biological changes in growing times and extent for plants and animals.
Whether the incremental temperature change in response to the incremental rise in CO2 is detrimental or ‘radical’ in its effects on human society and specifically agricultural production systems is uncertain. And has more to do with uncertainty about the flexibility and robustness of societal responses than the magnitude of the climate change already experienced and most likely in the pipeline…

🙂 Shrug, looking in a mirror Leif? Typical irrelevance or misdirection coupled with ad homs in replies from you when you don’t know what you’re talking about but like to pretend you do or deliberate distraction in an attempt to confuse to continue promoting AGWScience fiction memes. Don’t much care, I gave up expecting a straight answer from you a while back. Recall the last one? Let me known when you’re willing to actually interact with what’s being said.
As I mentioned earlier, there is no internal consistency from AGWScience fiction inc. Because here they describe the molecules of our atmosphere as ideal gases, nitrogen, oxygen and carbon dioxide, but exclude water vapour – why? Because they say water vapour is localised and doesn’t stay in the atmosphere for any length of time.. ??!
So, because AGWScience deliberately joins out of context or disproved concepts to its promotion of its ideology/science fiction, the unwary get the impression that molecules of carbon dioxide are zipping through empty space bouncing off the other molecules and so thoroughly mixing that it can’t become unmixed, and so is proportionally the same all through the atmosphere and that it can accumulate and stay up for hundreds and even thousands of years because ideal gases don’t have weight and volume relative to each other and therefore do not separate out. Believers of this science fiction package have no sense of how the real carbon dioxide moves in the atmosphere, the Carbon Life Cycle is a closed book to them. As is the Water Cycle, because explaining that would have to bring in that water vapour is lighter than Air and carries heat away from the Earth. Where they mention the Earth would be 67°C without the water cycle, it is garbled so the connection to real properties and processes can’t be made.
The whole real world is a closed book to those enmeshed in AGWScience. They argue from out of context laws and physical impossibilities because that is what they have been taught. Those producing the memes know very well what is possible and not from traditional science, blue visible Light cannot heat water..
Those real applied scientists working in various fields know that molecules are real, have real properties relative to each other, interact with each other in different ways, that attraction and volume is not negligible; see the etc. on the tutorvista link.

“Those real applied scientists working in various fields know that molecules are real, have real properties relative to each other, interact with each other in different ways, that attraction and volume is not negligible;”
If it is not negliable you will be able to give at least an estimate of how much the real atmosphere does deviate from the ideal gas law at the usual range of temperature, pressure and volume found in the real world.
Here’s a clue –
http://hyperphysics.phy-astr.gsu.edu/hbase/kinetic/waal.html
Note that the number of moles of gas involved is ma factor, the greater the amount of gas the closer to the ideal gas equations things become. For the total atmosphere the real applied scientists working on jet engine design for instance know that the deviation from the ideal gas laws is negligable and can be ignored.
It really only becomes a factor at very high temperatures and pressures, although as Leif has indicated, for light atoms like hydrogen and helium it isn’t much of a factor at the temperatures and pressures in the solar interior.
Before you can credibaly claim that a whole branch of science has egregiously ignored the difference between the ideal gas laws and the behavior of the atmosphere which might require the application of Van der Waals equation, or the Redlich–Kwong equation of state, or Soave modification of Redlich-Kwong or Peng–Robinson equation of state or even the Elliott, Suresh, Donohue equation of state; you need to show that they NEED to allow for these modifications – and don’t.
Do you have any evidence that the ‘real atmosphere’ needs these modifications to the ideal gas laws to describe climate interactions? Or that the ‘AGWscience’ does NOT use them where appropiate?
“Gases do not move at vast speeds through real air, they vibrate where they are – how sound travels: http://www.mediacollege.com/audio/01/sound-waves.html
Sound travels as a density variation and not as individual air molecules travelling from source to ear.
But the molecules of air ARE moving at vast speeds of around 1000 miles an hour, and bouncing around and off each other continually. Perhaps this will help you grasp this subject better –
http://www.uccs.edu/~tchriste/courses/PHYS549/549lectures/gasses.html
You might like to calculate the mean free path, the distance traveled between collisions for an air molecule at room temperature and pressure.

> Gases do not move at vast speeds through real air, they vibrate where they are
Vibrate in this context means moving back and forth, well not necessarily in line, more of bouncing around. In wind free conditions there’s no net movement, in a wind, air molecules are trending in the direction of the wind.
Ultimately sound is carried by air molecules, the pressure waves are carried by air molecules bouncing off each other. In near ideal gases (like air), the mean free path where they aren’t significantly interacting is long relative the distance where electrons are repelling each other during each bounce.
Sound travels about 1000 feet per second, some 300 m/s. This implies the average speed of air molecules away from the sound source is 300 m/s. The actual speed has to be significantly higher since molecules are really flying around in all directions. I don’t know what that speed is, but I wouldn’t call it a vast speed.
You note that air molecules vibrate – please describe how you envision the momentum of air molecules changes as they vibrate – that may help us understand how you see gases behave.

So, I was perusing the weather picture of the day link, and saw this one of the Black Forest in Germany:
http://weatherpictureoftheday.com/2011/05/27/black-forest-storms/
I was admiring the thunderheads, when I read the caption: “When the weather conditions are right the Black Forest in southern Germany can turn into a thunderstorm factory.” That got me thinking about all the trees that used to be in the United States that were cut down. All those forests producing clouds. So I decided to see if I could find a map showing the severity of these land use changes, and I found this one. I couldn’t get the website to work, and I’m a little pressed for time at the moment, but you’ll get the picture.

How much of the warming curve did IPCC attribute to lack of cloud cover from deforestation (or: the positive feedback on land use changes)? None, they consider land use changes as a regional effect, and do not consider the associated reduction in cloud cover from deforestation.

“For the record, the poster (Michael Tobis) stated that, “As far as I know, nothing in the published literature indicates anything larger than 0.3 W/m^2 peak-to-peak solar variability on decadal-to-century time scales.”
I said that this statement was wrong, and provided links to several data sources and published literature all using the much more common “approximately 0.1% or about 1.3 Watts per square meter (W/m2) peak-to-trough during the 11-year sunspot cycle” measured at the ”outer surface of Earth’s atmosphere”:”
Okay, one last time.
It depends on which -‘The Published Literature’- you are referring to.
If you confine yourself to the astronomy, solar physics research then it is very unlikely you will see the 0.3W/m2 peak-to-peak figure because they are not concerned with the terrestrial impact of the Sun, only in detecting, measuring, describing and ultimately explaining the variations.
If you confine yourself to the literature published on the climate you are unlikely to see the 1.3W/m2 because this is not comparable with the units used for all the other factors in the energy budget that are given in W/m2 over the EARTH SURFACE. The figure used in the published (Climate/Earth sciences) literature is almost invariably the 0.3W/m2 because this allows easy comparison with all the other energy fluxes.
When M Tobias used the 0.3W/m2 as a climate researcher he was being consistent, and correct, because that is the value of 0.1% solar variation on the Earth which is comparable with the other energy fluxes. If you are familiar with the climate science literature then this value is familiar and how it is derived from the top-of-atmosphere value is well known.
So accusing him of being in error about the magnitude of solar variation and suggesting he use google to correct his ‘mistake’….

Quite.

“We understand the key contributors of energy into ocean circulation, which I refer to as the causes.”
There are only three sources of energy contributing to ocean currents. Thermal energy from the sun, gravitational energy from the Earth and tidal interactions with the Moon/Sun and the rotational energy of the Earth.

“I agree that we have a “very little in the way of explanation” as to how all of these factors interact to generate specific Oceanic Oscillations. Are you suggesting that we should be ignoring the PDO, El Nino/La Nina, etc. until we are able to explain exactly why they occur?”
No, just that we should use them only as descriptions, not causes. I understand you think this is just semantics, not meaning, but it is a common mistake in science. A set of observations are manipulated into a reified parameter, index or statistically derived definition of a pattern of data. That is then used as IF it was an independent ‘object’ with causal properties.
It is only ever a glorified description.
We dont ignore El Niño events because they have a significant effect on the pacific weather for a year or two, with influences globally. The warmer and colder areas of the pacific surface follow a specific pattern. But that pattern of temperature is NOT an explanation for the temperature distribution.
Describing a weather pattern as an ‘El Niño’ event is only ever that, a description not an explanation.
That is why I am unable to answer you question – “Do you think that some portion of the increase in Earth’s temperature that occurred between 1975 and 2005 might be related to Ocean Circulation/Cycles, as indicated by the increase the Sea Surface Temperature that occurred in the pacific during the PDO Warm Regime? ”
Because it carries the implicit assumption in the ‘might be related’ term that the PDO and other ocean ‘cycles’ are related causally to temperature changes.
The best answer I can give that avoids this misconception is that the ocean ‘cycles’ we see are PART OF the warming observed between 1975 and 2005 (and since). They are a part of the total description we have of the system. They cannot have a primary causal role because they are energy neutral, they can only shape the timing of energy fluxes, and that probably only as a contingent response to the energy inputs and outputs.

There are only three sources of energy contributing to ocean currents. Thermal energy(1) from the sun, gravitational energy(2) from the Earth and tidal interactions(3) with the Moon/Sun and the rotational energy(4) of the Earth.
I do love the irony of a simple mistake directly after someone insults another person’s intelligence.

@-David Falkner
You have counted gravitational energy twice.
Tides and density stratification are different effects driven by the same source of energy.

“Even if we only do it by category I get 5, i.e.:
1. Solar Energy
2. Gravitational Effect
3. Orbital Energy
4. Rotational Energy
5. Geothermal Energy”
Okay, I’ll give you geothermal, would you agree that its total magnitude is about one third of the small variation in the solar ‘constant’ we have dissected in detail?…-grin-
What on Earth, or out of it is – 3. Orbital Energy and how does it move water ?
