This Inside Climate News article discusses whether global warming is causing hurricanes like Dorian to stall. Hurricanes Harvey and Florence also stalled, leading to extreme rainfall. Research shows it’s a global trend. Recent research shows that more North Atlantic hurricanes have been stalling as Dorian did, leading to more extreme rainfall. Their average forward speed has also decreased by 17 percent—from 11.5 mph, to 9.6 mph—from 1944 to 2017, according to a study published in June by federal scientists at NASA and NOAA.
This PBS article discusses whether climate change is making hurricanes stall. Over the last seven decades, hurricane stalling, which causes a storm to release massive amounts of rain on small areas, has become more common, research published in June in the journal Nature shows. But it is currently unclear if the trend is due to climate change or natural variation.
This Michael Mann and Andrew E Dessler article in The Guardian discusses the linkage between global warming and intensifying hurricanes. As oceans warm up, hurricanes get more intense. A recent study has shown that this is getting more common because of climate change, and indeed the past few years have seen many similar examples of this effect in action. Dorian was the fourth category 5 storm in just the last four years.
