I recently pointed out a great summary of the evidence in response to a climate change denialist:
More CO2 does worsen climate change: http://www.desmogblog.com/skeptics-handbook-carbon-dioxide-climate-change
Yes, Global Warming is real and it’s still happening: http://www.desmogblog.com/debunking-joanne-nova-climate-skeptics-handbook-global-warming-real-and-happening
Don’t miss this part:
“Finally, we have greenhouse gases. In this case, things work out well. Both the timing and magnitude of today’s warming are well-explained by greenhouse gases.
“This is why scientists conclude that humans are likely responsible for most of the warming of the last few decades. Greenhouse gases provide a reasonable explanation for the warming, while no other factor can explain the entire warming (though other factors, such as solar, might be playing a minor role).”
The climate models have it right: http://www.desmogblog.com/debunking-joanne-nova-climate-skeptics-handbook-part-3-climate-models-have-it-right
He apparently couldn’t get past the titles, even though the second one was right on point. There is no other explanation for the phenomena we are seeing.
But I guess the political nature of that site and the simplified nature of the explanation were just too off-putting. All right, fair enough. If you’re looking for an explanation that’s
this is the one for you. It’s called Advancing the Science of Climate Change and was published by the National Academy of Sciences last week. The National Academy of Sciences is a very prestigious body. Even conservative members of the U.S. Congress ask it to investigate scientific matters of public policy.
This is from the summary:
- Climate change is occurring, is caused largely by human activities, and poses significant risks for a broad range of human and natural systems; and
- The nation needs a comprehensive and integrated climate change science enterprise, one that not only contributes to our fundamental understanding of climate change but also informs and expands America’s climate choices
But don’t stop there. Please, feel free to read all 392 pages.
