Monday March 18th… 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).😉
Climate Change Targets Nebraska And The Midwest
Time after time after time over the last two plus years that I’m had this web site we have seen many instances of heavier than usual precipitation across the planet leading to flooding from climate change. In this universe end results act like a series of dominoes, one falling then another until there is an end state. This is what happened to Nebraska over the weekend from carbon pollution.
Now don’t get me wrong. There have always been instances of severe flooding across the Midwest, but what we are seeing now are record 50-500 year described floods that are enhanced by an overall warmer atmosphere produced by greenhouse gasses. A couple of days ago I described meteorologically why the “cyclone bomb,” which was the catalyst producing Midwestern flooding, was made stronger by climate change:
We can see an overall warmer atmosphere over North America the day that the cyclone bomb deepened in the western High Plains, despite very chilly conditions at the surface:
It’s not just the Climate Guy who is putting two and two together to come to the conclusion that global warming enhanced the bomb cyclone leading to severe flooding. Take a look at these videos and articles:
One of the best writeups on this latest stint of U.S. flooding is from Weather Underground:
Jeff Berardelli also makes the point that the jet stream was stuck most of the winter over the U.S. leading to storm after storm move over the Midwest burying them in snow, which led to most of the severe flooding. Jet streams getting stuck are one sign of climate change.
It may take more than a year for attribution studies to scientifically peg climate change to the cyclone bomb and associated strength, high winds, heavy snow and rain, and rapid melting in its warm sector, so look for those. Keep in mind this particular system. Doubtless there will be other tragic climate change related weather systems affecting the U.S. and the planet, which might make us forget about what happened in March 2019 between now and 2020.
I’ll be adding more information on the flooding in today’s post as it crosses my radar.
Here is some more climate and weather information from Monday:
(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. In most instances click on the pictures of each tweet to see each article.)
Here are Monday’s reports of ETs:
