Where’s the warming?

Where’s the warming? by Ed Morrissey/Hot Air

Carbon emissions over the past decade actually exceeded predictions by the UN’s Intergovernmental Panel on Climate Change (IPCC), no thanks to the global economic recession. According to their anthropogenic global-warming theories, global temperatures should have risen significantly as a result. James Taylor at Forbes wonders what happened:

Global greenhouse gas emissions have risen even faster during the past decade than predicted by the United Nations Intergovernmental Panel on Climate Change (IPCC) and other international agencies. According to alarmist groups, this proves global warming is much worse than previously feared. The increase in emissions “should shock even the most jaded negotiators” at international climate talks currently taking place in Bonn, Germany, the UK Guardian reports. But there’s only one problem with this storyline; global temperatures have not increased at all during the past decade.


The evidence is powerful, straightforward, and damning. NASA satellite instruments precisely measuring global temperatures show absolutely no warming during the past the past 10 years. This is the case for the Northern Hemisphere mid-latitudes, including the United States. This is the case for the Arctic, where the signs of human-caused global warming are supposed to be first and most powerfully felt. This is the case forglobal sea surface temperatures, which alarmists claim should be sucking up much of the predicted human-induced warming. This is the case for the planet as a whole.


If atmospheric carbon dioxide emissions are the sole or primary driver of global temperatures, then where is all the global warming? We’re talking 10 years of higher-than-expected increases in greenhouse gases, yet 10 years of absolutely no warming. That’s 10 years of nada, nunca, nein, zero, and zilch.

Be sure to check out the links, which show charts over varying time sets, but which all show basically the same thing: no real change over longer periods of time. Not in the Arctic, which Taylor notes was supposed to be the canary in the coal mine, nor in the northern hemisphere, or the globe overall. That’s even true for just the last decade, but it’s especially true over the period of several decades. Periods of high amplitudes in warming are matched with low amplitudes.

Earlier this week, I linked to a couple of articles from physicists who have expressed considerable skepticism of the AGW hysteria, including one who worked in Australia’s climate-change ministry. It’s worth revisiting his observation about the science, its models, and what’s missing:

This is the core idea of every official climate model: For each bit of warming due to carbon dioxide, they claim it ends up causing three bits of warming due to the extra moist air. The climate models amplify the carbon dioxide warming by a factor of three — so two-thirds of their projected warming is due to extra moist air (and other factors); only one-third is due to extra carbon dioxide.


That’s the core of the issue. All the disagreements and misunderstandings spring from this. The alarmist case is based on this guess about moisture in the atmosphere, and there is simply no evidence for the amplification that is at the core of their alarmism.


What did they find when they tried to prove this theory?


Weather balloons had been measuring the atmosphere since the 1960s, many thousands of them every year. The climate models all predict that as the planet warms, a hot spot of moist air will develop over the tropics about 10 kilometres up, as the layer of moist air expands upwards into the cool dry air above. During the warming of the late 1970s, ’80s and ’90s, the weather balloons found no hot spot. None at all. Not even a small one. This evidence proves that the climate models are fundamentally flawed, that they greatly overestimate the temperature increases due to carbon dioxide.


This evidence first became clear around the mid-1990s.

It’s becoming even more clear now. If carbon increases and the predicted warming didn’t follow, then the obvious conclusion is that the hypothesis regarding cause and effect is incorrect — and the missing hot spots are even further evidence of this.
