Well apparently they did, and boy is it surprising:
NASA satellite data from the years 2000 through 2011 show the Earth's atmosphere is allowing far more heat to be released into space than alarmist computer models have predicted, reports a new study in the peer-reviewed science journal Remote Sensing. The study indicates far less future global warming will occur than United Nations computer models have predicted, and supports prior studies indicating increases in atmospheric carbon dioxide trap far less heat than alarmists have claimed.
Well, I for one am actually glad of this. It should relieve my ancestors to know that their reckless industrialism may not have destroyed the future as quickly as feared. The extreme weather of the last few years is simply that: an extreme. Not the new normal. Or at least, the if the new normal is hot, it isn't as likely caused by humans as it is the natural sway and variation of the Earth itself.
However, even if we can breathe a (cool) sigh of relief about global temperatures, it does not mean humans aren't absolutely destroying the Earth. Here, I point to harvested fish biomass reductions and a beautiful (though apocalyptic) graphic by David McCandless:
Global temperatures have little or nothing to do with the way we are fishing the oceans. Or the way we are causing (through agriculture and hunting/harvesting) the most massive extinction event in 75million years.
But at least when aliens visit our lifeless blue marble in a few thousand years, having traveled here with utmost speed, excited to meet us, after receiving our first radio transmissions into deep space in the 1940's...and they arrive here only to exhume the ruins of our long gone and mostly eroded civilizations...at least then the weather will be nice.
