Scientists have known for years that global warming can exacerbate storms. Barbara Hollingsworth, “U.S.With Hurricane Florence making landfall in the Carolinas, Super Typhoon Mangkhut headed for the Philippines, and Hurricanes Harvey, Irma and Maria fresh in our minds, many are asking what role climate change is playing in these disasters.Warming Increases Wind Shear, Reduces Hurricanes, Climate Model Shows,” ScienceĬlimate At A Glance is a Project of The Heartland InstituteĮmail: Florence Nears the East Coast September 12, 2018.

Even with the slight uptick in the number of tropical storms in 2021, it is still below the peak recorded in Source: Ryan N. This figure shows that global hurricane and tropical cyclone activity is not increasing. 5 The Gulf of Mexico also recently benefited from its longest hurricane-free period in recorded history (2013–16).įigure 1: Graph showing global hurricane frequency since 1970 Figure 1. 4 Additionally, America’s most vulnerable state for hurricanes, Florida, concluded an 11-year period without a landfalling hurricane of any size in 2016, the longest such period in recorded history. The United States also recently experienced the fewest number of hurricane strikes in any eight year period in recorded history (2009 through 2017). That is the longest such period in recorded history. States recently went more than a decade (2005 through 2017) without a major hurricane-a hurricane measuringĬategory 3 or higher-making landfall. Most importantly for Americans, the impacts hurricanes have on the United States are at an all-time low. The IPCC’s findings are well supported by objective hurricane and tropical storm data. “Identifying past trends in TC metrics remains a challenge,” a statement that essentially admits scientists have yet to identify a solid measurable upward trend in the data. In its 2018 interim report, IPCC stated there is “only low confidence for the attribution of any detectable changes in tropical cyclone activity to anthropogenic influences.” 1 Similarly, in the IPCC’s AR6 WG1 report, released in August 2021, the IPCC noted, The Intergovernmental Panel on Climate Change (IPCC) has largely agreed with this view. Florida, America’s most hurricane-prone state, recently underwent its longest period in recorded history without any hurricanes.ĭevastating hurricanes occurred long before the invention of automobiles and coal-fired power plants,Īnd real-world hurricane activity shows little, if any, impact from global warming. The United States recently experienced its fewest total hurricanes in any eight-year period. The United States recently went through its longest period in recorded history without a major hurricane strike. 
IPCC agrees, finding no increase in the frequency or severity of hurricanes. There has been no increase in hurricanes as the planet has modestly warmed.View this page in our printable booklet (PDF) here: Hurricane Florence Nears the East Coast September 12, 2018.
