Scientific Review Shows ‘Unambiguous’ Evidence of Global Warming
A newly released year-long international scientific review of the evidence for global warming has concluded that the evidence is even stronger than the IPCC maintains.
The review, published in the journal Wiley Interdisciplinary Reviews: Climate Change, found several “fingerprints” of warming that had not been established by the time of the last IPCC assessment but were now unambiguously present.
One is human-induced climate in the Antarctic, the last continent where regional warming has been demonstrated.
There is also new evidence of warming in the oceans, which is having several effects. The subtropical Atlantic is becoming saltier; the extra salinity could in turn alter ocean currents.
Another effect of ocean warming is increasing evaporation, leading to more humidity in the atmosphere and changing rainfall patterns. …
The review is based on a forensic comparison of the pattern of changes expected from man-made warming with those that would result from other factors such as changing solar radiation and purely natural variations.
A separate study by Russian and US scientists, published today in the journal Science, shows methane, a powerful greenhouse gas, is escaping from the seafloor of the warming Arctic Ocean more rapidly than has been suspected.
