The deadly storm that completely destroyed eight U.S. states in early April, killing at least 24 peoplegetting worse Climate changeAccording to a study released this week.
World Weather Attribution Analysis by the Climate Science Group Found that artificial global warming makes Record downpour About 9%. A powerful storm Destroyed Houses, roads and farmland.
From April 3 to April 6, the storm swept across the Midwest and South, dumping record rainfall in Kentucky, Tennessee, Arkansas and other states. The study found that four days of rain were the heaviest ever in the area. The study determined that the sea surface temperature in the Gulf of Mexico is unusually warm due to climate change, and that in the Gulf of Mexico is unusually warm, which is about 1.2 degrees Celsius (2.2 degrees Celsius) higher due to climate change.
This makes the storm 14 times more likely, according to WWA analysis.
Researchers say that while strong predictions and early warnings may reduce the scope of damage, they are concerned about the impact. Continuous staff shortage in the National Meteorological Administration.
According to Fredi Otto, co-founder of World Weather Attribution, many of its on-site offices are nervous, with nearly half now facing a vacancy rate of more than 20%, while 30 offices without senior meteorologists operate without senior meteorologists, one of the authors of the report, co-founder of World Weather Attribution and a senior lecturer in climate science at the Imperial College London, London.
These offices are responsible for issuing real-time warnings and coordinating with emergency management staff to ensure the safety of the community.
As climate change becomes more frequent and harsh weather, the pressure on the insurance market is becoming more and more obvious. Homeowners in high-risk areas have seen it Their insurance costs As companies adapt to growing risks, it has risen sharply.
"We estimate that the highest zip code for the most risky zip code has risen by an average of $1,100, from 2020 to 2024," said Ben Keys, a professor of real estate and finance at the Wharton School of Wharton at the University of Pennsylvania.
No Rapid transfer from fossil fuelsExtreme weather is expected to become more common and intense, the researchers said.
According to the study, if global warming reaches 2.6 degrees Celsius (4.7 degrees Fahrenheit) - according to current policies, the researchers with world weather attributes, four-day rainfall events (such as the amount seen in early April) could increase by another 7%, possibly 7%, and possibly triple.
"It really is what we understand what this means, and what it means for the future," said study co-author Shel Winkley. "What does this mean for these areas of these back-to-back events? What does this mean for the way we are built or where we rebuild, or if we do the reconstruction? Will this be a place that will be livable in the future? If so, how do we make sure it is livable and safe?"
