A federal committee has published a draft of the nation's third climate assessment report, a comprehensive analysis of the latest and best peer-reviewed science on the extent and impacts of global warming on the United States.
None of the body's findings are entirely new, but the report suggests that evidence is now stronger and clearer than ever that the climate is rapidly changing -- primarily as a result of human activities, including the copious burning of fossil fuels. Observed weather extremes are on the rise, and the possible connection between at least some of these events and human-induced climate change is also more strongly supported by the science.
The nation can expect increased impacts on everything from crops to fresh water supplies, and better and broader national plans for adaptation are needed, the assessment noted.
The draft report, which was prepared by the so-called National Climate Assessment Development Advisory Committee and written and amassed by a group of 240 scientists, will be subject to a three-month period of review and public comment.
"Climate change presents a major challenge for society," the committee's leadership said in a letter addressed to the American people. "This report and the sustained assessment process that is being developed represent steps forward in advancing our understanding of that challenge and its far-reaching implications for our nation and the world."
In an emailed statement, Gene Karpinski, the president of the League of Conservation Voters, said the report confirms what many Americans already know. "Hurricane Sandy and the historic droughts, floods and heat waves happening across the country aren't a fluke, but the result of a climate warming much faster than previously thought," he said. "If we put off action on climate change, the costs of addressing its impacts will only rise and this extreme weather will be just the beginning. This report should serve as a wake-up call that it's time to act.
Now the thumpers want to have a say on this too!
Let me clarify too... It's not than I don't believe in climate change.. I certainly do. Climate proxies provide evidence that our climate has changed in the past (yeah, as recently as 1000 AD and up).
My problem is the insufficient statistical correlations between CO2 emissions and global warming. It simply has not been proven. I'll even say it has not been proven YET.
Unfortunately for you 99% of scientists don't agree with you. Exactly what is the problem with having more fuel efficient cars and reducing corporate pollution?? And yes it would be good if people didn't mow their lawns every week in the summer and drive a block to the store to get a carton of milk. It's nonsense to say that reducing pollution isn't good even if by some miracle it doesn't cause global warming.
Again, no doubt you have not read the last 10 years of IPCC reports. You just blindly repeat what others say without attempting to read the science. Fine, believe in anthropogenic climate change. If you do you better be damn sure you're 100% vegan... otherwise you're completely hypocritical in your quest.
Switching to an all vegetable lifestyle (including your clothes, soaps, etc) is the most effective method any individual in the US can take to combat "global warming" Ahh... but most of those climate change activists buy their Priuses and CFL bulbs... and call it a day.
So RVGA, Wally -- since you both seem to be climate change "believers" are you currently vegan? If not..
U.S. Energy Secretary Samuel Bodman told a news conference that the report was "sound science" and "As the president has said, and this report makes clear, human activity is contributing to changes in our earth's climate and that issue is no longer up for debate." Kurt Volker, Principal Deputy Assistant Secretary for European and Eurasian Affairs, said, "We support the recent IPCC report, in which U.S. scientists played a leading role."
One group, the free-market Competitive Enterprise Institute, filed multiple lawsuits arguing that the findings were not subjected to federal guidelines for scientific research.
CEI settled its legal challenges with the Bush administration, which subsequently suppressed use of the report by other branches of the federal government in their implementation of policies.
The next full climate assessment was not published until 2009, after President Barack Obama took office.
