Thursday October 4th… Dear Diary. The main purpose of this ongoing post will be to track United States extreme or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials)😊. Here is today’s main climate change related topic:
Wild And Wet In The Eastern U.S. — Another Sign Of Climate Change
My topic for the day posts have been getting a little lengthy lately, so this one will be short and to the point. What we have seen in the United States this summer going into the fall, particularly in the East, is not normal.
Another case in the odd weather department is a severe weather outbreak that occurred in recent days across a fairly high latitude for October. Most early fall severe weather outbreaks occur across the southern U.S. northward through the central Plains. This one did not:
This would be an impressive tornado outbreak in the East for any time of year, but in October it’s unheard of
Map of confirmed tornadoes from Tuesday’s event in the Northeast. 14 confirmed so far with surveys still ongoing
With roughly a quarter of 2018 still to come, a large percentage of Eastern US locations have already exceeded their average annual rainfall total. Two locations (Wilmington NC and Lumberton NC) have already broken their all time yearly rainfall record.
September 2018 is the hottest month of September in Europe since the beginning of the readings according to
@CopernicusECMWF(+ 1.68 °c/norm) ahead of 2011 and 2006. This is the 4th month of 2018 to be 1st in Europe with april, May and august!
On the globe, it’s the 6th hottest.
(As usual, this will be a fluid post in which more information gets added during the day as it crosses my radar, crediting all who have put it on-line. Items will be archived on this site for posterity.)
How much will sea levels rise by the end of the 21st Century? Here the most current broad-based, peer-reviewed scientific assessment, the 4th US National Assessment 2017. Worst case is 8 feet or 2.5 meters. Science has moved on since the last IPCC report! https://science2017.globalchange.gov/
Le semestre avril-septembre est de très loin le plus chaud jamais observé en
#Europe avec une anomalie continentale de +1.79°C /moy 1981-2010, dépassant largement le précédent record (+1.06°C en 2016) avec une marge de 0.73°C ! #climat #climate
🌡️ the April-september semester is by far the warmest ever observed in
#Europe 🇪🇺 with a continental anomaly of + 1.79 °c/moy 1981-2010, far exceeding the previous record (+ 1.06 °c in 2016) with a margin of 0.73 °c! #climat #climate Data: @CopernicusECMWF
Today’s high temperature of 91 in
#Atlanta ties the daily record for October 4th, which was set in 1954. Today and yesterday have been the first two days to reach 90 in Atlanta in October since 1954. #gawx
A Central American Gyre (#CAG) has continued to sit and spin over Central America. Embedded within are multiple mesovorticies forming in response to active convection stretching incipient vorticity.
