Cold Facts on the Globe’s Hottest Years

Sen. James Inhofe misleadingly claimed that the statistics behind the globe’s likely hottest years on record — 2014, 2015 and 2016 — were “meaningless” because the temperature increases were “well within the margin of error.” Taking into account the margins of error, there’s still a long-term warming trend.
