Over the next 2 or 3 entries on this blog, I shall be reporting, courtesy of the World Resource Institute, on high speed winds.
Scientists have known for years that global warming can exacerbate storms. But our understanding of the connection between hurricanes and climate change has evolved significantly in just the past year. Here’s what the cutting-edge science shows.
If storms hover above an area of land for long periods of time, they continue to dump rain, amplifying the risk of flooding. Very recent research has established a connection between warmer temperatures and the slowing of hurricane movement. A recent study in Nature found that from 1949 to 2016, the speed of tropical cyclones declined by 10 percent globally; North Atlantic tropical cyclones slowed down 20 percent over land areas during the same period. This slowing is part of the reason Hurricane Harvey caused so much damage when it stalled over Texas last year.
So, keep the field drains and ditches in order and let the rain get away – we can expect more of it.
