Oklahoma Spring Rains Strengthened by Global Warming

Global warming is behind that record setting rainfall we experienced last May.

The Oklahoma Climatological Survey reported a statewide average of 14 inches of rain in May, well above the previous record set in 1941.

It’s no secret that Oklahoma gets a lot of rain in the spring but a newly published study says global warming is the reason why we saw so much of it this year. Dr. Shih-Yu (Simon) Wang, the assistant director of the Utah Climate Center, is the lead author of the study. The Guardian has a good recap.

Global warming acts like a domino effect…a rise in temperatures in one part of the world, impacts rising seawaters in another part of the world, impacts precipitation in another part of the world…and so on. Dr. Wang studied how global warming impacted El Niño.

“El Niño tends to increase late-spring precipitation in the southern Great Plains and this effect has intensified since 1980. There was a detectable effect of anthropogenic global warming in the physical processes that caused the persistent precipitation in May of 2015: Warming in the tropical Pacific acted to strengthen the teleconnection towards North America…”              

You can expect to see many more studies like this linking global warming to natural disasters. Some may continue to deny it but the Earth doesn’t care.

 

 

Megadroughts are Megabad

Oklahoma could be ground zero to some one of the worst droughts in a millennium. A new report in the journal Science Advances says the Great Plains and Southwest portion of the U.S. are in line for megadroughts over the next 100 years. Those are droughts that last more than 20 years. Researchers say we could see droughts that last as long as 35 years or more. This part of the world hasn’t seen droughts like that since the 1100s.

You guessed it, the drier conditions are mostly a result of rising greenhouse gases, according to the report.

My grandfather was a wheat farmer in north central Oklahoma all of his life. I remember visiting his farm as a child. The TV was never on except to watch the weather report and then no one could move or say a word. That weather report was his lifeline. You could sense his anguish if he needed rain and it wasn’t coming. I can’t imagine what a megadrought will do to our Oklahoma farmers.

I wonder when our state and national leaders will take this seriously? If reports like this don’t change some minds, I’m not sure what will.
