Meanwhile, Mars is warming without human help.
So for the past several thousand years the sea could be rising an average of 1.48 mm and now it is 1.51 mm. Based on the evidence given in the article that could be a true statement even though the actual difference is .03 mm.
Global ocean levels are rising twice as fast today as they were 150 years ago, and human-induced warming appears to be the culprit.
Are they saying non-human produced global warming would have no effect on ocean levels?
IIRC: I read somewhere that global warming would cause the Greenland Ice Sheet to lose mass while the Antarctic Ice Sheet might actually gain mass. Where is this extra water coming from?
