Fast Company: This map of the U.S. heating up is horrifying. Show it to every climate denier you know. The U.S. looks like it’s on fire.
Was it a hot day? Or is the world actually getting hotter over time? It’s hard to be sure on a day-to-day basis. Isn’t summer always a little too sweltering? Aren’t there always a few unseasonably warm days in winter?
A new map proves it’s not just you: The U.S. really is getting hotter, whether you live in California, Florida, or Indiana. The National Oceanic and Atmospheric Administration (NOAA) has tracked U.S. weather for more than a century. And every decade, it releases the latest 30-year average. An average is considered the “new normal.” This month, NOAA released its latest new normal, the U.S. map from 1991 to 2020.)
To put it bluntly, the map looks bad—especially when compared to the last 120 years of averages. What we see is that the nation has transitioned from a cool blue to a hot red—marking a 2.5-degree shift that happened in a blink of Earth’s history. The U.S. looks like it’s on fire.
