This third post in our series on the spurious links between climate change and extreme weather examines the incidence of hurricanes – powerful tropical cyclones that all too dramatically demonstrate the fury nature is capable of unleashing.
Although the UN’s IPCC (Intergovernmental Panel on Climate Change) has noted an apparent increase in the strongest (category 4 and 5) hurricanes in the Atlantic Ocean, there’s almost no evidence for any global trend in hurricane strength. And the IPCC has found “no significant observed trends” in the number of global hurricanes each year.
Hurricanes occur in the Atlantic and northeastern Pacific Oceans, especially in and around the Gulf of Mexico; their cousins, typhoons, occur in the northwestern Pacific. Hurricanes can be hundreds of miles in extent with wind speeds up to 240 km per hour (150 mph) or more, and often exact a heavy toll in human lives and personal property. The deadliest U.S. hurricane in recorded history struck Galveston, Texas in 1900, killing an estimated 8,000 to 12,000 people. In the Caribbean, the Great Hurricane of 1780 killed 27,500 and winds exceeded an estimated 320 km per hour (200 mph). The worst hurricanes and typhoons worldwide have each claimed hundreds of thousands of lives. (Source)
