As summer approaches and Trump considers withdrawing from the Paris Climate Agreement, it is worth looking at some data on global warming. The graph on the left shows global temperature change over the past 100 years measured by both NASA and the National Oceanic and Atmospheric Administration (NOAA). Though the temperature bounces around year-to-year, the overall trend is clearly a steady and dramatic rise from about 1970 on. Based on these and other data, a staggering 97% of climate scientists and scientific studies endorse human-caused global warming that is directly related to CO2 and other greenhouse gases. This scientific consensus means that finding a climate scientist who denies human-caused global warming is just as fluky as flipping a coin five times, and getting heads each and every time. In stark contrast, only 69% of Democrats and a mere 23% of Republicans agree with this scientific consensus.
