The data – and proxy records such as tree rings and ice cores – shows this year is likely to be the hottest in at least 125,000 years. Right now, the world is on track for as much as 3.1C (5.58F) of warming based on already pledged emissions cuts, assuming they are fulfilled. Copernicus Climate Change Service reported early Thursday that the year is headed for a temperature anomaly of more than 1.55C (2.79F) above preindustrial levels. Last year fell just shy of the 1.5C threshold relative to the 1850-1900 average.
When I was a kid we had to put warm clothes under the costume to go trick or treating in the snow. Now we’re a week into Nov and it’s rained for about a day and a half so far.
