The cold truth about climate change
Deniers continue to insist there's no consensus on global warming.
Well, there's not. There's well-tested science and real-world observations.

Feb. 27, 2008 The more I write about global warming, the more I realize I share some things in common with the doubters and deniers who populate the blogosphere and the conservative movement. Like them, I am dubious about the process used by the U.N. Intergovernmental Panel on Climate Change (IPCC) to write its reports. Like them, I am skeptical of the so-called consensus on climate science as reflected in the IPCC reports. Like them, I disagree with people who say "the science is settled." But that's where the agreement ends.
The science isn't settled -- it's unsettling, and getting more so every year as the scientific community learns more about the catastrophic consequences of uncontrolled greenhouse gas emissions.

In Conclusion:
.
The result, as a number of studies have shown, is that the sensitivity of the world's climate to human emissions of greenhouse gases is no doubt much higher than the sensitivity used in most IPCC models. NASA's Hansen argued in a paper last year that the climate ultimately has twice the sensitivity used in IPCC models.
.
The bottom line is that recent observations and research make clear the planet almost certainly faces a greater and more imminent threat than is laid out in the IPCC reports. That's why climate scientists are so desperate. That's why they keep begging for immediate action. And that's why the "consensus on global warming" is a phrase that should be forever retired from the climate debate.
