And the article above quoted a scientist mentioning that the CO2 just might be able to stop that: "We were quite shocked by the warm surface temperatures observed at the NEEM ice camp in July 2012," said Dahl-Jensen. "It was raining at the top of the Greenland ice sheet, and just as during the Eemian period, meltwater formed subsurface ice layers. While this was an extreme event, the present warming over Greenland makes surface melt more likely, and the predicted warming over Greenland in the next 50-100 years will very likely be so strong that we will potentially have Eemian-like climate conditions." The Greenland ice core layers—formed over millennia by compressed snow—are being studied in detail using a suite of measurements, including stable water isotope analysis that reveals information about temperature and greenhouse gas levels and moisture changes back in time. Lasers are used to measure the water stable isotopes and atmospheric gas bubbles trapped in the ice cores to better understand past variations in climate on an annual basis—similar in some ways to a tree-ring record. The results from the Nature study provide scientists with a "road map" of sorts to show where a warming Earth is headed in the future, said White. Of the nine hottest years on Earth on record, eight have come since the year 2000. In 2007 the Intergovernmental Panel on Climate Change concluded that temperatures on Earth could climb by as much as 11 degrees F by 2100. Increasing amounts of carbon dioxide in the atmosphere from sources like vehicle exhaust and industrial pollution—which have risen from about 280 parts per million at the onset of the Industrial Revolution to 391 parts per million today—are helping to raise temperatures on Earth, with no end in sight, said White. The ice cores do not and cannot support CAGW theory because they're about the ancient past. "Unfortunately, we have reached a point where there is so much carbon dioxide in the atmosphere it's going to be difficult for us to further limit our impact on the planet," White said. "Our kids and grandkids are definitely going to look back and shake their heads at the inaction of this country's generation. We are burning the lion's share of oil and natural gas to benefit our lifestyle, and punting the responsibility for it."
