Så Laura var på samma nivå som en orkan 1856? Är det bekräftat att Laura drevs på av klimatförändringar men inte orkanen 1856?
Laura skulle ju vara på samma nivå som Katrina.
8 miljader dollar vs 125 miljarder dollar
240km/h vs 280km/h
Vad är det du vill bevisa? Varför denna grundlösa alarmism?
Här är en analys av Laura och en referens till en färsk orkanstudie:
Climate change didn't cause Hurricane Laura but it did make the storm worse
(CNN)Hurricane Laura was a formidable storm when it made landfall in Louisiana on Thursday.
Laura broke multiple records, including the highest water level ever recorded at the Mermentau River gauge at Grand Chenier location. The gauge topped out at 17.14 feet, more than 4 feet above the previous high of 13 feet from Hurricane Audrey in June 1957, according to the US Army Corps of Engineers.
Another notable record was that Laura was the seventh named storm to make landfall in the US so far in 2020, the most to do so before the end of August (four tropical storms and three hurricanes). This begs the question, why are so many more named storms impacting the US?
The planet has warmed significantly over the past several decades, causing changes in the environment in which extreme weather events are occurring.
A study of 40 years of satellite data of global storms by researchers at the University of Wisconsin and the National Oceanic and Atmospheric Administration (NOAA) found that the probability of storms reaching major hurricane status -- Category 3 or above with sustained winds of 110 mph or higher -- has increased decade after decade.
The study found that hurricanes, typhoons, and tropical cyclones worldwide are becoming stronger and potentially more deadly as the globe warms due to the climate crisis.
"The change is about 8% per decade," Jim Kossin, author of the study, told CNN in May when the study was released. "
