Over 7,000 Record Temperatures.. on an Interactive Map

March 29th, 2012 by


Well, yeah, to put it simply, that map is freakin’ full of heat records! Record high temperatures since March were staggeringly more numerous than record cold temperatures across the U.S. Thousands upon thousands of heat records; just a few hundred cold records. The ratio is apparently 17-1 this year so far for daily records (through March 27), and 33-1 for monthly records!

Surprised I don’t hear Inhofe or FOX News chiming in about this…

Here are some more notes from Climate Central:

This interactive map draws on the National Climatic Data Center’s database. You can explore the records state-by-state, weather station by weather station. For the most impressive view, zoom out to see the U.S. as a whole, and click “play month” for the month of March. You’ll note a surge of warm temperature records start moving across the country, starting on about March 12 and lasting for more than a week in some spots.

In recent years, record daily highs have been outpacing record daily lows in a pattern that has been shown to be inconsistent with natural climate variability alone. So far in 2012, the daily record high to record low ratio has been 17-to-1 through March 27, for monthly record highs compared to monthly record lows the ratio has been a whopping 33-to-1 in favor of warm temperature records.

Of course, you can use this tracker to see cold records too. For example, in January of this year, multiple cold weather records were set in Alaska, as temperatures dipped below -60°F!

Note that because of the large number of records this interactive is processing, it may be a bit slow to load at times.
