The Intergovernmental panel On Climate Change (IPCC) has finished its fifth report, and more scientists than ever now agree that climate change is real, is caused primarily by humans and is going to create massive problems in the latter half of this century.
The polar icecaps are melting faster than we thought they would; seas are rising faster than we thought they would; extreme weather events are increasing. Have a nice day!
…Appearing exhausted after a nearly two sleepless days fine-tuning the language of the report, co-chair Thomas Stocker called climate change “the greatest challenge of our time,” adding that “each of the last three decades has been successively warmer than the past,” and that this trend is likely to continue into the foreseeable future.
…It is now 95 percent likely that human spewed heat-trapping gases — rather than natural variability — are the main cause of climate change, according to today’s report. In 2007 the IPCC’s confidence level was 90 percent, and in 2001 it was 66 percent, and just over 50 percent in 1995.
What’s more, things are getting worse more quickly than almost anyone thought would happen a few years back.
The worst case scenarios say there will be a global mean temperature rise of as much as 5.5 degrees Celsius (9.9 degrees farenheit) by 2100, and a sea level rise of up to 1 meter (39.4 inches).

Of particular relevance for denialist Republican Americans: areas where there is already a severe risk of drought are expected to get worse – much worse. By the end of the century, the US South-West is likely to be largely uninhabitable. It certainly cannot sustain the many large cities and irrigation intensive farming that are current practice. Nor can it sustain fracking for oil at the current rate.
What you gonna do when the wells run dry, folks? Be a refugee?
I mean, seriously, your investment in dumb denial of science will extend to doing that to your family?
