NOAA’s own trend calculator helps confirm ‘the pause’ and lack of ocean warming in the 21st century

NCDC_OTI_2000-2013People send me stuff. Yesterday I got a note suggesting I have a look at what NOAA/NCDC’s “climate at a glance” was showing for trends in the 21st century so far.

I decided to take a look. Continue reading

The 2014/15 El Niño – Part 14 – Warm Water Recirculated?

Figure 0 - Page 12 from Wekly ENSO UpdateThere may still be a chance for an El Niño during the 2014/15 ENSO season. A new “pocket” of warm subsurface water has formed in the western equatorial Pacific. See the note in the page from the most-recent NOAA Weekly ENSO Update to the right. (Please click on illustration for full-sized image.) In their update, NOAA also makes note of that anomaly during their discussion of the Hovmoller on their page 15. That subsurface temperature anomaly appears to have been caused by the recirculation of warm water from the earlier downwelling (warm) Kevin wave, not by another westerly wind burst.  Come along, I’ll show you.

Solar Cycle Driven Ocean Temperature Variations

What Slow Fourier Transforms can tell us.

Guest essay by Stan Robertson, Ph.D., P.E.

On May 3, 2014, an article on WUWT by Willis Eschenbach entitled, The Slow Fourier Transform (SFT) was posted. As he noted, the amplitude of the Slow Fourier Transform components are in the same units as the fitted data, intervals of arbitrary length and irregular data can be used and periodicities rather than frequencies are automatically extracted. In addition to rediscovering a very useful mathematical tool, Willis went on to show that there were apparently no variations of temperature associated with solar cycle variations for several long term temperature records. Now my normal inclination would be to say that if Willis didn’t find any there probably aren’t many to be found. But, on the other hand, as I showed in an October 10, 2013 WUWT article entitled The Sun Does It: Now Go Figure Out How!, it does not take much of a temperature variation to represent a very significant solar contribution to ocean surface temperatures and heat content.

Taking Keating’s $30,000 skeptic challenge seriously, part 1

Contradictory contest criteria have been rectified via Keating “clarification” clarification

Guest post by Alec Rawls

At first glance retired physics teacher Christopher Keating’s challenge appears to be an obvious bait and switch. It opens as an invitation to “global warming skeptics” who charge that “the science doesn’t support claims of man-made climate change.” The central “claim of man-made climate change” is the IPCC’s assertion in AR5 that: “It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century” (AR5 WGI SPM p. 17, upped from “very likely” in AR4 and “likely” in the Third Area Report). So wait a minute. All we have to do is demonstrate that this assertion of great certainty that human activity caused most late 20th century warming is clearly unsupported by the available reason and evidence and Keating will give us $30,000? That is easily done. But then the first stated rule of his contest asserts a very different criterion: Continue reading

The law of unintended climate consequences at work – study says 23% of warming in Europe since 1980 due to clean air laws

(Via the HockeySchtick)

A paper published today in Geophysical Research Letters finds that clean air laws which greatly reduced sulfur dioxide emissions explain 81% of the “brightening” of sunshine and 23% of the surface warming in Europe since 1980. However, the authors note “this phenomenon is however hardly reproduced by global and regional climate models.”

June 2014 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly Update

Sorry this update is late. I got sidetracked with the post about Risbey et al. (2014), and the post about the new climate model, now with knobs.

This post provides an update of the data for the three primary suppliers of global land+ocean surface temperature data—GISS and NCDC through June 2014 and HADCRUT4 through May 2014—and of the two suppliers of satellite-based lower troposphere temperature data (RSS and UAH) through June 2014.

New paper finds the climate to be ‘highly nonlinear’

But, we already knew that from experience. However, a lot of models still treat climate as a mostly or near linear process, and that’s why they aren’t performing particularly well at even predicting the present.

(via the Hockeyschtick) A paper published July in Science says “the climate system can be highly nonlinear, meaning that small changes in one part can lead to much larger changes elsewhere.” Continue reading

Onwards, Ever Onwards

Guest Post by Willis Eschenbach

I’ve been remiss in my duties as travel correspondent. When last heard from, the gorgeous ex-fiancee and I were rolling out of Butte, Montana in a rented car. At the end of the day, we arrived in Missoula, Montana, one of the two goals of the trip. It’s the home of a most interesting friend. He’s a mad keen environmentalist of the best kind, a bird expert, PhD scientist, conservation biologist of the highest order … and the kind that missoulaloves to hunt and fish. A couple years ago he and I and another friend were out hunting grouse in the snow, and he’d lent me a pair of his hunting gloves before we started out.

Unfortunately or fortunately, when I went home I’d forgotten his gloves were in the pocket of my jacket. When I came across them, I thought about mailing them, but then I realized that they were the perfect excuse for a return trip to Montana. It’s a perfect Montana plan, drive 1,500 miles to return a pair of hunting gloves. And now we were in Montana, in Missoula, his town. We took a room in a hotel and as always, went out for a walk. It’s a lovely town, on the banks of the Clark Fork river. Continue reading

California’s future energy pipe dream

I wonder how they’ll manage to put 25,000 offshore wind turbines in place after seeing the long battle (back to 2001 for the first permit) to get Cape Wind in Massachusetts approved with enviros switching sides to protect viewsheds, and it still isn’t built. I can’t see California’s sensitive coastline to go any easier, and never mind the other projects they propose, which will have their own challenges. The biggest failure of the plan seems to be lack of backup power for when the wind doesn’t blow, the sun doesn’t shine, and the tides are lower than usual. – Anthony

Climate Science; Winning The Science Battle, But Losing the Policy War

Essay by Dr. Tim Ball (Elaboration of my Heartland Climate Conference Presentation)

We’re drowning in information and starving for knowledge. Rutherford Rogers

So-called climate skeptics, practicing proper science by disproving the hypothesis that human CO2 is causing global warming, achieved a great deal. This, despite harassment by formal science agencies, like the Royal Society, and deliberate neglect by the mainstream media. It combined with an active and deliberate Public Relations campaign, designed to mislead and confuse. Most people and politicians understand little of what is going on so the Intergovernmental Panel on Climate Change (IPCC) strategy of using created science for a political agenda moves ahead.

‘Climate models not only significantly over-predict observed warming in the tropical troposphere, but they represent it in a fundamentally different way than is observed’

LTmodels-observationsNew Paper by McKitrick and Vogelsang comparing models and observations in the tropical troposphere

This is a guest post by Ross McKitrick (at Climate Audit). Tim Vogelsang and I have a new paper comparing climate models and observations over a 55-year span (1958-2012) in the tropical troposphere. Among other things we show that climate models are inconsistent with the HadAT, RICH and RAOBCORE weather balloon series. In a nutshell, the models not only predict far too much warming, but they potentially get the nature of the change wrong. The models portray a relatively smooth upward trend over the whole span, while the data exhibit a single jump in the late 1970s, with no statistically significant trend either side. Continue reading

The Tyranny of Tautology

A response to A conversation with Dr. Roger Pielke Jr.

Willis Eschenbach described the Kaya Identity as being “trivially true”, his opinion is uncontested by Dr Pielke Jr., whose only retort in its defence was, ‘the math is simple’.

The Kaya is a simple Identity, used as a tautological instrument. To deny this, would be to deny the very heart of its utility. The algebraic cancellation and isolation of its terms is de rigueur for its use. Continue reading

Uncertainty in the dirt: another climate feedback loop

From the Carnegie Institution  Climate change and the soil

Climate warming may not drive net losses of soil carbon from tropical forests

Washington, DC — The planet’s soil releases about 60 billion tons of carbon into the atmosphere each year, which is far more than that released by burning fossil fuels. This happens through a process called soil respiration. This enormous release of carbon is balanced by carbon coming into the soil system from falling leaves and other plant matter, as well as by the underground activities of plant roots.

I wonder how this dedicated weather observer feels about having his readings adjusted by NCDC?

In my travels surveying weather stations around the United States, I met many dedicated observers like this one. It is sad indeed that their painstakingly recorded data by observers like this one gets adjusted by NCDC to give results that aren’t the same as what they observed. I have some comments, data, and photos about the station that follow, but let me say to Mr. Hendrickson first; thank you sincerely for your service and dedication.

New paper finds transient climate sensitivity to doubling of CO2 is about 1°C

A new paper published in Ecological Modelling finds climate sensitivity to doubled CO2 concentrations is significantly lower than estimates from the IPCC and climate models which “utilize uncertain historical data and make various assumptions about forcings.” The author instead uses a ‘minimal model’ with the fewest possible assumptions and least data uncertainty to derive a transient climate sensitivity of only 1.093C:

OCO: I can see your house emitting CO2 from here

OCO-2 Data to Lead Scientists Forward into the Past

NASA’s Orbiting Carbon Observatory-2, which launched on July 2, will soon be providing about 100,000 high-quality measurements each day of carbon dioxide concentrations from around the globe. Atmospheric scientists are excited about that. But to understand the processes that control the amount of the greenhouse gas in the atmosphere, they need to know more than just where carbon dioxide is now. They need to know where it has been. It takes more than great data to figure that out.  Continue reading

‘Goldilocks zone’ exoplanets would not be habitable without an ocean

UEA: Oceans moderate the climate

Story submitted by Eric Worrall

h/t The Register – University of East Anglia researchers have challenged the view that any planet in the Goldilocks zone (the right distance from a star so water is likely to be liquid) is likely to be habitable.

New research shows that without an ocean, and the right rate of rotation, a planet is likely to experience extremes of temperature which make it unlikely to harbour life.

Claim: natural variation ‘masked’ global warming, creating ‘the pause’

Statistical analysis shows pattern consistent with pre-industrial temperature swings, study concludes

From McGill University’s Shaun Lovejoy

Statistical analysis of average global temperatures between 1998 and 2013 shows that the slowdown in global warming during this period is consistent with natural variations in temperature, according to research by McGill University physics professor Shaun Lovejoy.

In a paper published this month in Geophysical Research Letters, Lovejoy concludes that a natural cooling fluctuation during this period largely masked the warming effects of a continued increase in man-made emissions of carbon dioxide and other greenhouse gases.

Deep Oceans Are Cooling Amidst A Sea of Modeling Uncertainty: New Research on Ocean Heat Content

Guest essay by Jim Steele, Director emeritus Sierra Nevada Field Campus, San Francisco State University and author of Landscapes & Cycles: An Environmentalist’s Journey to Climate Skepticism

Two of the world’s premiere ocean scientists from Harvard and MIT have addressed the data limitations that currently prevent the oceanographic community from resolving the differences among various estimates of changing ocean heat content (in print but available here).3 They point out where future data is most needed so these ambiguities do not persist into the next several decades of change. As a by-product of that analysis they 1) determined the deepest oceans are cooling, 2) estimated a much slower rate of ocean warming, 3) highlighted where the greatest uncertainties existed due to the ever changing locations of heating and cooling, and 4) specified concerns with previous methods used to construct changes in ocean heat content, such as Balmaseda and Trenberth’s re-analysis (see below).13 They concluded, “Direct determination of changes in oceanic heat content over the last 20 years are not in conflict with estimates of the radiative forcing, but the uncertainties remain too large to rationalize e.g., the apparent “pause” in warming.”

A courtesy note ahead of publication for Risbey et al. 2014

People send me stuff. In this case I have received an embargoed paper and press release from Nature from another member of the news media who wanted me to look at it.

The new paper is scheduled to be published in Nature and is embargoed until 10AM PDT Sunday morning, July 20th. That said, Bob Tisdale and I have been examining the paper, which oddly includes co-authors Dr. Stephan Lewandowsky and Dr. Naomi Oreskes and is on the topic of ENSO and “the pause” in global warming. I say oddly because neither Lewandowsky or Oreskes concentrates on physical science, but direct their work towards psychology and science history respectively.

Tisdale found a potentially fatal glaring oversight, which I verified, and as a professional courtesy I have notified two people who are listed as authors on the paper. It has been 24 hours, and I have no response from either. Since it is possible that they have not received these emails, I thought it would be useful to post my emails to them here. Continue reading
