Our Version 5.5 global average lower tropospheric temperature (LT) anomaly for April, 2013 is +0.10 deg. C, down from +0.18 deg. C in March (click for large version):
Not surprisingly, the cooling appears to be confined to the Northern Hemisphere…the global, hemispheric, and tropical LT anomalies from the 30-year (1981-2010) average for the last 16 months are: (more…)

In a recent study published in Procedings of the National Academy of Sciences (PNAS), NASA scientist James Hansen and two colleagues find that whereas “extremely hot” summer weather ”practically did not exist” during 1951-1980, such weather affected between 4% and 13% of the Northern Hemisphere land area during 2006-2011. The researchers infer that human-caused global warming is “loading” the “climate dice” towards extreme heat anomalies. They conclude with a “high degree of confidence” that the 2003 European heat wave, the 2010 Russian heat wave, and the 2011 Texas-Oklahoma drought were a “consequence of global warming” and have (as Hansen put it in a recent op-ed) ”virtually no explanation other than climate change.”
In a recent post, I reviewed studies finding that the aforementioned anomalies were chiefly due to natural variability. In another post, I summarized an analysis by Patrick Michaels and Chip Knappenberger, who conclude that “the 2012 drought conditions, and every other [U.S.] drought that has come before, is the result of natural processes, not human greenhouse gas emissions.” (more…)

NOTE: For those who are offended by my bringing up Al Gore in this post (but are apparently not offended by Gore falsely accusing scientists like me of being ‘global warming deniers’), I suggest you just focus on the evidence I present. You are invited to offer an alternative explanation for the evidence, but I will not allow you to divert attention from it through irrelevant “copy and paste” factoids you have gathered from other scientific publications. If you persist, I will be forced to adopt the RealClimate tactic of deleting comments, which so far I have been able to avoid on this blog. We’ll just call it “fighting fire with fire”.
As I and others have pointed out, the 20th Century runs of the IPCC climate models have, in general, created more virtual warming in the last 50 years than the real climate system has warmed.
That statement is somewhat arguable, though, since the modelers can run a number of realizations, each with its own “natural” year-to-year internal climate variability, and get different temperature trends for any given 50-year period. (more…)

LiveScience.com posted an article yesterday where the usual IPCC suspects (Gavin Schmidt, Kevin Trenberth, and Andy Dessler) dissed our recent paper in in the journal Remote Sensing.
Given their comments, I doubt any of them could actually state what the major conclusion of our paper was.
For example, Andy Dessler told LiveScience:
“He’s taken an incorrect model, he’s tweaked it to match observations, but the conclusions you get from that are not correct…”
Well, apparently Andy did not notice that those were OBSERVATIONS that disagreed with the IPCC climate models. And our model can quantitatively explain the disagreement. (more…)

Here’s the global average sea surface temperature (SST) update from AMSR-E on NASA’s Aqua satellite, updated through yesterday, July 7, 2011:
The anomalies are relative the existing period of record, which is since June 2002.
As can be seen, the SSTs have not quite recovered from the coolness of the recent La Nina.
Something else I track is the ocean cloud water anomalies, also from AMSR-E, which I have calibrated in terms of anomalies in reflected sunlight based upon Aqua CERES data: (more…)

Surely it’s time for climate-change deniers to have their opinions forcibly tattooed on their bodies.
- Richard Glover (HT:National Times.Com)
Richard Glover and Dr. Donald Brown are two very different men, in different nations, who work towards a common goal. Each man believes that human pollution has driven a series of chemical and physical changes in the Earth’s atmosphere. Each man believes this will damage the world around us and must be fought. Neither man has any ability to objectively prove their belief. Neither man will let that lack of knowledge stand in the way of enforcing their views upon others. Both men indulge in unethical behavior that demonstrates yet another cost that pseudo-science imposes on modern society. (more…)

Since the issue of deep ocean warming (below 700 m depth) has been raised in the comments section, I have re-run the forcing-feedback model for the following two observations: 1) a net 50 year warming of 0.06 deg. C for the 0-2000 meter layer, and (2) a surface warming of 0.6 deg. C over the same period. The results suggest a net feedback parameter of 3 W m-2 K-1, which corresponds to a climate sensitivity of 1.3 deg. C from 2XCO2, which is below the 1.5 deg. C lower limit the IPCC has placed on future warming.
Weak Warming of the Oceans 1955-2010 Implies Low Climate Sensitivity
Assuming that the Levitus record of global oceanic heat content increase is anywhere near accurate, what might it tell us about climate sensitivity; e.g., how much global warming we might expect from increasing atmospheric carbon dioxide concentrations? As we will see, the oceans have not warmed nearly as much as would be expected if the climate system really is as sensitive as the IPCC claims. (more…)

In this special report, NOAA claims rapid warming of the oceans and record ice melt.
”Analysis by the National Climatic Data Center revealed that March 2011 was the 13th warmest on record since 1880. Temperatures in much of the U.S., Siberia, and Africa yielded land surface temperatures that were 1.49 deg F (0.83 deg C) warmer than the 1971-2000 comparison period; Canada, China and Southeast Asia, and Australia were cooler than average. The average global ocean surface temperature was 0.65 deg F (0.36 deg C) above normal, but as La Nina continues to weaken, this number may actually increase.”
Lets look at the UAH plot of temperatures:
Dr. Roy Spencer notes: “The global average lower tropospheric temperature anomaly for March 2011 fell to -0.10 deg. C, with cooling in both the Northern and Southern Hemispheric extratropics, while the tropics stayed about the same as last month. ”This is relative to the 1979-2010 mean. (more…)

Thousands of climate dignitaries representing almost every national government on Earth flew to Cancun, Mexico, for the great event. Security precautions were extensive: Battleships could be seen from the beach while thousands of soldiers and police lined the jam-packed roads. It was time for the 16th “Conference of the Parties,” or COP16 for short. The annual summit, which was held this year from November 29 through December 10, is an extravaganza of the United Nations Framework Convention on Climate Change, or UNFCCC. The previous year’s COP15 in Copenhagen was massive — over 50,000 attendees in all, not counting protesters. It was well publicized, too. But after the spectacular failure of COP15 to deliver a binding climate treaty, and with little hope of securing one this time, expectations for COP16 were purposefully set low. (more…)

Cancun, Mexico
I dined with Dr. Roy Spencer as the Atlantic rollers swished and crashed against the long, sandy beach here in Cancun. We ate coconut-crusted camarones. Appropriately, shrimps in the Spanish-speaking world are named after the British Prime Minister, the truest of true believers in the New-Age religion that is the Church of “Global Warming”.
Cameron, or “Dave”, as he matily likes to be known, had been careful not to reveal his blind faith in the febrile fatuities of the forecasters of fashionable fatalism to his followers in Not The Conservative Party before they picked him as their leader: but, in his very first speech as Supreme Shrimp, he made it plain to the fawning news media that Saving The Planet would be his very firstest priority, yes indeedy.

“The American Geophysical Union plans to announce that 700 researchers have agreed to speak out on the issue. Other scientists plan a pushback against congressional conservatives who have vowed to kill regulations on greenhouse gas emissions.”
A new article in the LA Times says that the American Geophysical Union (AGU) is enlisting the help of 700 scientists to fight back against a new congress that is viewed as a bunch of backwoods global warming deniers who are standing in the way of greenhouse gas regulations and laws required to same humanity from itself.
Scientific truth, after all, must prevail. And these scientists apparently believe they have been endowed with the truth of what has caused recent warming.
The message just hasn’t gotten across.
We skeptics are not smart enough to understand the science. We and the citizens of America, and the representatives we have just elected to go to Washington, just need to listen to them and let them tell us how we should be allowed to live.
OK, so, let me see if I understand this. (more…)

Since I just provided the September 2010 global tropospheric temperature update, I decided it was time to update the global SST data record from the AMSR-E instrument flying on Aqua.
The following plot, updated through yesterday (October 4, 2010) shows that both the global average SST, and the Nino3.4 region average from the tropical E. Pacific, continue to cool.
(click on the plot for the full-size, undistorted version. Note that the global values have been multiplied by 10 for easier intercomparison with Nino3.4)
Past experience (and radiative-convective equilibrium) dictates that the global tropospheric temperature, still riding high at +0.60 deg. C for September, must cool in response to the cool ocean conditions.
But given Mother Nature’s sense of humor, I’ve given up predicting when that might occur
How much evidence will it take to quiet the claim that hurricanes are increasing in frequency due to global warming?
Global Warming crusaders are particularly fond of promoting the idea that we are having a profound impact on hurricane activity—they seem to never let an event go unclaimed. At World Climate Report (WCR), we have reviewed dozens of papers from the leading scientific journals presenting scant evidence to support a strong link between global warming and hurricane activity, and we hope you never get bored with these essays.
The literature never sleeps, and yet another major article has appeared recently in a leading journal with results well-suited for our never-ending review of this subject. (more…)
