UAH Global Temperature Anomaly Down by .12C in February

UAH Global Temperature Update for February 2014: +0.17 deg. C

(Note, my original headline number was unintentionally misleading, using a percentage to illustrate the drop rather that the absolute number. While the calculation was correct, it gave an impression of overall magnitude across the entire scale rather than the month to month change. It has been corrected. – Anthony)

FEBRUARY 2014 (1)

Notes on data released March 5, 2014:

Warm temperature anomalies in the Arctic during February indicate a

displacement of cold air from that region to other areas, such as from

North America through the North Atlantic into eastern Russia,

according to Dr. John Christy, a professor of atmospheric science and

director of the Earth System Science Center at The University of

Alabama in Huntsville.

Compared to seasonal norms, the coldest place in Earth’s atmosphere in

February was over the southwestern corner of Canada’s Saskatchewan

province near the town of Eston, where temperatures were as much as

4.68 C (about 8.42 degrees Fahrenheit) cooler than seasonal norms.

With Arctic air holding sway over much of North America, temperatures

in the Arctic were generally warmer than normal in February. Compared

to seasonal norms, the warmest departure from average in February was

over the Arctic Ocean northeast of Svalbard, a group of islands about

halfway between Norway and the North Pole. Temperatures there were as

much as 6.16 C (11.1 degrees Fahrenheit) warmer than seasonal norms.

Archived color maps of local temperature anomalies are available on-line at:

http://nsstc.uah.edu/climate/

As part of an ongoing joint project between UAHuntsville, NOAA and

NASA, Christy and Dr. Roy Spencer, an ESSC principal scientist, use

data gathered by advanced microwave sounding units on NOAA and NASA

satellites to get accurate temperature readings for almost all regions

of the Earth. This includes remote desert, ocean and rain forest areas

where reliable climate data are not otherwise available.

The satellite-based instruments measure the temperature of the

atmosphere from the surface up to an altitude of about eight

kilometers above sea level. Once the monthly temperature data is

collected and processed, it is placed in a “public” computer file for

immediate access by atmospheric scientists in the U.S. and abroad.

Neither Christy nor Spencer receives any research support or funding

from oil, coal or industrial companies or organizations, or from any

private or special interest groups. All of their climate research

funding comes from federal and state grants or contracts.

Meanwhile, In Australia, BOM releases this piece of propaganda.
They are going to look awfully stupid if the temperatures do start to drop. 🙂

Things are a bit cooler here in Brisbane. Temperatures are barely nudging 30. Autumn has started, but nice and sunny here today. My cat is playing happily in the garden. The girls are still wearing skimpy tops and minuscule shorts that almost cover their bottoms. Tell me again, why is Global Warming a Bad Thing?

One things for sure. It’s been a very long time now since there was ANY warming. This cannot be explained by Greenhouse Theory.

Yes
However WUWT is also for those without training above a high school education and at least in the USA most people haven’t the foggiest what a standard deviation is or have even heard of the term.
It always is smart to remember we have an unseen unheard ‘Peanut Gallery’ who are the people we really want to get information out to.

The best way to quantify changes is in Kelvin and as a % change in absolute temperature, I think. But then those numbers would not be scary and they alone do not quantify energy content which is of the utmost interest here.
The metric most valuable in knowing if the earth is warming or cooling is a precise (as precise as possible) measurement of frozen water.
A global temperature is indeed very difficult to calculate. Relative changes in global temperature can best be approximated based on satellite data.
But again, temperature is not the same as energy. Moist air at temperature x holds more energy than dry air at that same temperature. The energy content differences is very significant. So temperature is not the end all metric. If our climate is less moist, for example, the temperatures might show an increase, but that does not mean there is more energy in the area being measured. Said another way, a higher temperature might also be associated with less energy than another measurement of lower temperature!
So this “Global Temperature” metric is not as meaningful as some seem to think.
Still, I like seeing the temperatures not cooperate with the AGW prognosticators!

“Wow the tropics are a cooling! Anything to do with a slight La Nina – to La Nada condition?”
Two things: On average, the tropics tend not to change that much (I experienced the same temperatures in Lagos, Nigeria in 1964 as I did in 1998 and I note it is still about 28-29C.). I believe this due to Willis’s Thermostat phenomenon which puts a ceiling on maximum temperature. Second, a cooling tropics is much more worrisome if it persists for one reason or another. Even the “Thermostat” doesn’t have the tools necessary to limit movement in this direction (it can retard it by going clear sky, but after that there is little that can be done). Since the cooler tropics remain warmer than the poles, heat will continue to flow away from the tropics. If this, the earth’s central heating system, cools for an extended period, we will see its warming effect on the poles diminish until polar amplification finally then goes the other way, and remember we are only talking a couple of degrees here. The planet has seen this before! It ain’t unprecedented.

The anomaly map sure looks like recharge discharge in the Arctic. An entirely natural consequence of La Nina recharged heat making its way up North to be sent into oblivion back out to space.

BTW, what ever happened to the always entertaining 3rd order polynomial fit to the data?

Maybe it’s being held in reserve for the day when the data turns down in the way it was hinting.

Well, for people who get their news from comedians this probably comes as a surprise, but Sarah never said that. The line actually comes from a Saturday Night Live skit (reference http://www.snopes.com/politics/palin/russia.asp).

This winter in the NH has been a real eye opener for me.
As l now think am beginning to understand the weather patterns that would cause the NH to slip in and out of ice ages.

Do we know-not-muchers take it to be .17C above 14.5C?
The real average temperature in February is about 12.0 C and about 15.8 C in July. See:
http://theinconvenientskeptic.com/2013/03/misunderstanding-of-the-global-temperature-anomaly/
So for February, an anomaly of 0.17 C means about 12.17 C. (So for July, an anomaly of 0.17 means about 15.97 C.)

Compare:

i.e. 0.98 deg/70 years – by UAH Global Temperature Feb. 2014
With

These estimates, published in leading scientific journals, point to climate sensitivity per doubling of CO2 most likely being under 2°C for long-term warming, with a best estimate of only 1.3-1.4°C for warming over a seventy year period.

Remarkable!

What would the headline be if the anomaly went negative?
———————————————————————————
An appropriate headline would be “Catastrophic Global Warming is Officially Dead”.
But we may have to wait a few more years. In the meantime your criticism of percent makes sense.

The Central England Temperature for Feb was +1.8C above long term mean yet the UAH lower trop anomaly has almost all of England in the -0.5 to -1.5 C band. Same basis period.
Obviously these data runs are derived from different ways of measuring and are not sampling the exact same layers in the atmosphere, but clearly for this month of Feb the UAH is not accurate as a proxy for surface temperature as far as England is concerned and whilst not having looked at the data in detail, I doubt for western Europe as a whole which has had a generally very mild winter.
UAH continues to show the 3 to 4 year cycle on the 13 month running mean.

“Last time I checked down was considered negative”
Well, negative is negative; it’s currently +0.17. What if it went to -0.01, say, and then back the following month to +0.17. In percent?
**************************************************
I get -106% then +1800%. This is related to why my investments are going down in value.
