JeanMarc "all human activity only accounts for 5% of the atmospheric carbon dioxide"
Actually, since the dawn of the Industrial Age, we have increased global atmospheric carbon dioxide levels by over 40%, from 270 ppm to 397 ppm. And temperatures have risen 0.8 C, not 0.5 as you contend. Meanwhile, the Arctic has lost 80% of its mass and its volume as compared to 1979. Greenland lost over 600 billion tons of ice in 2012 (as compared to its average between 1979 and 2003 of 125 billion tons). Antarctica is gaining in sea ice, but the net loss in its land ice is 100 billion tons per year. These are sobering numbers.
