Calif. Gov. Brown mocked for cliaming humans could responsible for a warming of 25 degrees
Claims that 2014 and 2015 were the hottest years on record are meaningless when you consider how little they set records by (seven hundredths of a degree Fahrenheit and 29 hundredths of a degree, respectively). In fact, the uncertainty in the 2014 temperature was twice as much as the amount by which the record was supposedly set. Sea level rise has also been unremarkable in the past century. There has been no recent acceleration, and the current rate of rise is less than one tenth that of 8,000 years ago. Geologists tell us that the oceans have been rising since the end of the last glacial period, 15,000 years ago. There has been no overall change in the incidence and severity of extreme weather in the past century, either. As in the case of temperature and sea level, the contribution of our emissions to extreme weather must have been very small indeed.
