Carbon dioxide only causes 1.1°C of warming if it doubles. That’s according to the IPCC. Did you know? The real game is water. Researchers made guesses about humidity and clouds in the early 1980s and they built these guesses into their models. We now know they were wrong, not about carbon, but about water in the form of humidity and clouds. Here’s how the models can be right about carbon and wrong about the climate. 7.5 out of 10 based on 11 ratings […] December 5th, 2009 | Tags: Climate Models, Evidence, Feedback, Missing Hot Spot, The Skeptics Handbook II | Category: Global Warming |  Print This Post | | These maps and graphs make it clear just how brazenly unscientific the Hockey Stick is.
It’s clear that the world was warmer during medieval times. Marked on the map are study after study (all peer-reviewed) from all around the world with results of temperatures from the medieval time compared to today. These use ice cores, stalagmites, sediments, and isotopes. They agree with 6,144 boreholes around the world which found that temperatures were about 0.5°C warmer world wide. 8.3 out of 10 based on 38 ratings […] December 3rd, 2009 | Tags: Briffa (Kieth), Evidence, Hockey Stick Graph, Little Ice Age, Loehle (Craig), McIntyre (Steven), McKitrick (Ross), Medieval Warm Period, Steven McIntyre, The Skeptics Handbook II, Wegman Report | Category: AGW socio-political, Global Warming | Print This Post | | Thanks to Eric Raymond, famous computer guru and leader of the open-source movement, at ESR, we can see what those sophisticated climate modelers were doing. They’ve found the code from the leaked files, and Eric’s comment is: This isn’t just a smoking gun, it’s a siege cannon with the barrel still hot. Here’s the code. The programmer has written in helpful notes that us non-programmers can understand, like this one: “Apply a very artificial correction for decline”. You get the feeling this climate programmer didn’t like pushing the data around so blatantly. Note the technical comment: “fudge factor”. 6.6 out of 10 based on 8 ratings […] November 30th, 2009 | Tags: Climate Models, ClimateGate, Evidence, Models, Satire & Parody | Category: Global Warming | Print This Post | | The headline is tongue in cheek, but the message is serious. Look at these pictures of NOAA’s U.S. temperature stations. These thermometers on the ground have recorded faster temperature rises than sensors on satellites and weather balloons.
Lucky heat doesn’t rise off asphalt…

It appears Steve McIntyre (volunteer unpaid auditor of Big-Government-Science) has killed the Hockey Stick a second time…
The details are on the last three days of Steve McIntyre’s site Climate Audit, and summed up beautifully on Watts Up. The sheer effrontery and gall appears to be breathtaking. The Briffa temperature graphs have been widely cited as evidence by the IPCC, yet it appears they were based on a very carefully selected set of data, so select, that the shape of the graph would have been totally transformed if the rest of the data had been included. Kieth Briffa used 12 samples to arrive at his version of the hockey stick and refused to provide his data for years. When McIntyre finally got hold of it, and looked at the 34 samples that Briffa left out of his graphs, a stark message was displayed. McIntyre describes it today as one of the most disquieting images he’s ever presented.

Michael Hammer previously calculated that if the IPCC were right, the oceans should have absorbed a lot more heat, but just how much? He has revised his previous calculation after discovering an error. Now instead of oceans missing as much as 90% of the heat capacity, they are missing less, but it’s still around two-thirds. Its a lot of energy that somehow, somewhere, is not being absorbed. Where is the energy that greenhouse gases are supposedly ‘trapping’? Not in the air, and not in the water. What sort of radiative imbalance is this? Not one to get scared of. Naturally, as always, Michael is keen for people to check his numbers and give us feedback. Here is another example of a skilled expert doing pro bono work because he is concerned at the state of the science and the unnecessary damage to our society that it will bring. Michael Hammer has around 20 patents in the field of spectroscopy, that means he’s produced work that’s so useful and original that his employers have shelled out hundreds of thousands of […] July 14th, 2009 | Tags: Evidence, Hammer (Michael), Oceans | Category: Global Warming | Print This Post | | There are 2014 updates on this topic: Ocean temperatures – Is that warming statistically significant? IPCC in denial. “Just-so” excuses use ocean heat to hide their failure. There has been a change in direction by the alarmists, as shown by their new “Synthesis Report.” The independent scientists noticed it during the Wong-Fielding meeting. The alarmists have abandoned air temperatures as a measure of global temperature, because the air temperature graphs are just too hard to argue with (like the second figure below, from the Skeptics Handbook). Instead they’ve switched to ocean temperatures, which they often disguise as ocean heat content (a huge number like 15×10²² Joules sounds much more scary than the warming it implies of 0.003° C/year). All three pages of the Synthesis Report that deal with ‘evidence’ are about factors or trends that tell us nothing about whether or not the warming is due to carbon emissions. If God put the galaxy in a toaster, sea levels would rise, ocean heat content would increase, and ice would melt. Notice how the graph above from the Synthesis Report that came out this month doesn’t include the last six years of data?

The big temperature picture. Graph and insight from Dr Syun Akasofu (2009 International Conference on Climate Change, New York, March 2009). The global temperature has been rising at a steady trend rate of 0.5°C per century since the depths of the little ice age in the 1700s (when the Thames River would freeze over every winter; the last time it froze over was 1804). On top of the trend are oscillations that last about thirty years in each direction: 1882 – 1910 Cooling 1910 – 1944 Warming 1944 – 1975 Cooling 1975 – 2001 Warming In 2009 we are where the green arrow points, with temperature leveling off. The pattern suggests that the world has entered a period of slight cooling until about 2030. 8.7 out of 10 based on 19 ratings […] April 3rd, 2009 | Tags: Akasofu (Dr Syun), Evans (David), Evidence, Little Ice Age | Category: Global Warming | Print This Post | | Science based ideas are falsifiable, whereas religious ones are not (thanks Karl Popper).

[…] October 30th, 2008 | Tags: Evidence, Evidence (What is it?), Logic & Reason, Science | Category: Global Warming | Print This Post | | The gap between real world data and thermometers is a make-or-break issue for the AGW theory. The models predict a hot-spot in the atmosphere above the tropics, but the weather balloons (called radiosondes) can’t find any sign of it. Most claims that the hot-spot has been found are not providing any new data, they are just massaging the same old numbers with a different statistical tool. Here are three variations (though the third is not a statistical-spin, it’s just nonsense). 1–Some AGW supporters claim that Santer et al has found the hot-spot. But his paper boils downs to a statistical reanalysis that suggests that due to noise and error, the hot-spot might be there. Santer hasn’t actually found the missing hot spot. He has a case, but it’s not a strong one. The statistical counterargument is at Climate Audit. 5.5 out of 10 based on 10 ratings […] October 30th, 2008 | Tags: Evidence, Feedback, Hot Spot, JoNova's Favourites, Missing Hot Spot, Water Vapor | Category: Global Warming | Print This Post | | The ‘Hotspot’ is crucial to the climate debate. If greenhouses gases are warming the planet that warming will happen first in the cold blob of air 8-12 km above the tropics. It’s freezing cold up there, but it ought to be slightly less freezing cold thanks to greenhouse gases. All 20-odd climate models predict warming there first—it’s the fingerprint of greenhouse gas warming, as opposed to warming by some other cause, like solar magnetic effects, volcanic eruptions, solar irradiance, or ozone depletion etc etc.
Look at A above, the greenhouse gas fingerprint is markedly different from the rest and dominates the overall predicted pattern in graph F. The big problem for the believers of AGW is that years of radiosonde measurements can’t find any warming, as shown in part E of Figure 5.7 in section 5.5 on page 116 of the US CCSP 2006 report
