It ’s rain harder across most of the U.S. and mood alteration is to blame , newfangled enquiry has found .
A newpaper publishedin Geophysical Research Letters has found that the country is seeing heavier rainfall as the clime changes . investigator at Northwestern University get in touch their findings to the fact that as the satellite becomes affectionate , air begin to maintain more moisture , theWashington Post reported .
In the past , scientists have used something called the Clausius - Clapeyron coitus as a way to measure how much more rainfall is likely as the planet becomes warmer . This equating holds that for every arcdegree Celsius ( 1.8 Fahrenheit ) warmer the air becomes , it can accommodate on to about7 % more moisture .

In the report , the research worker compared historic haste data of two meter full stop — between 1951 - 1980 and 1991 - 2020 — within 17 dissimilar clime region in the U.S. This helped the northwest researcher conclude that precipitation intensity for both rain and blow had increased for most of the nation since the middle of last century , but specially throughout the Midwest , southerly country , and the East Coast , accord to Northwestern Now .
research worker could n’t detect change in precipitation for areas out West , including area like the West Coast or the Rocky Mountains , but did conclude that when it rains east of the Rocky Mountains , there is about 5 % more rainfall in the 1991 - 2020 full point , liken to the earlier period .
The researcher point out that go after how climate alteration is stir regular weather patterns could also help us understand extreme weather as well . “ When people take how climate change has sham weather , they often expect at utmost weather events like floods , heatwaves and droughts,”Daniel Horton , the cogitation ’s aged writer , tell Northwestern News . “ For this particular study , we want to look at the non - uttermost events , which are , by definition , much more common . What we find oneself is pretty simple : When it rains now , it rains more . ”
More rain , even if it is n’t a lot more , can increase the likelihood of flooding throughout the res publica . This is only made worse byrising sea level . And lowering rainfall also increase the likeliness of landslides — a study publishedearlier this yearpredicted more instances of these for the U.S. as well .
The U.S. has live several “ thousand - year rainfall ” events this summertime alone . This include heavy rain that caused widespread implosion therapy throughoutSaint LouisandKentuckythis past July . thaw temperature have also been connected tohurricanes dropping more rainas they move north .
