“What Global Warming?” asks the conservative-funded Toronto Sun newspaper, marveling at the fact that in winter, we’re having snow. While the Toronto Sun asks a rhetorical question, a clear answer to that question is provided by NASA’s Goddard Institute for Space Studies, which has assembled global temperature observations on land and sea dating back to 1880 and moving ahead with new observations every month. The following is a graph visualizing the record of global temperature, measured relative to the 1951-1980 average, for the month of January from 1880 to 2017:
January 2017 was the third-hottest January for the globe in the NASA record, surpassed only by January 2016 and a prior peak in January 2007. The trend of global warming over the historic period is clear. Only if you ignore the data, look at the snow outside your window, and forget about years past does this startling change manage to disappear.
