The vehicle left the road and into a canal where it sunk, state police said in a news release.
Extreme rainfall closely linked with the climate crisis
Extreme rainfall and increased rainfall rates are closely linked with warming temperatures and the climate crisis
“The frequency and intensity of heavy precipitation events across the United States have increased … and are expected to continue to increase over the coming century,” according to the US National Climate Assessment in 2018.
This is leading to more 1-in-5-, 1-in-10-, 1-in-100-year-type extreme rainfall events that lead to catastrophic flash flooding.
These trends are consistent, secondo gli scienziati, with what is expected in a warming world, as warmer temperatures cause more evaporation which leads to higher levels of water vapor in the atmosphere, which can in turn lead to more frequent and more intense rainfall.
Louisiana has experienced extreme, climate-fueled rainfall before with disastrous consequences, such as in 2016 when deadly flash floods were studied by scientists and found to have been made at least 40% more likely and 12% per 35% more intense because of human greenhouse gas emissions.
