‘Misrepresents its own findings…No one defending’ it – Dr. Roger Pielke Jr. on study claiming ‘climate change’ is making hurricanes ‘stronger’: ‘Media hype, Gross misrepresentation, Questionable science’

Hurricanes are not getting worse

An August 2019 NOAA statement concluded: “It is premature to conclude … that global warming has already had a detectable impact on hurricane activity.” The NOAA statement added that U.S. landfalling hurricanes “show a slight negative trend’ since ‘late 1800s.” 

Norwegian Professor Ole Humlum explained in his 2018 “State of the Climate Report”: “Tropical storm and hurricane accumulated cyclone energy (ACE) values since 1970 have displayed large variations from year to year, but no overall trend towards either lower or higher activity. The same applies for the number of hurricane landfalls in the continental United States, for which the record begins in 1851.”

Dr. Roger Pielke, Jr. noted that the federal National Climate Assessment released in 2018 ignored one of its own expert reviewers, who wrote: “National Hurricane Center going back to the 1800s data clearly indicate a drop in the decadal rate of US landfalling hurricanes since the 1960s … instead you spin the topic to make it sound like the trends are all towards more cyclones.”

In 2019, extreme weather expert Dr. Roger Pielke, Jr. explained: The WMO (World Meteorological Organization) concluded, “no observational studies have provided convincing evidence of a detectable anthropogenic influence specifically on hurricane-related precipitation,” but also that an increase should be expected this century … The WMO assessment concludes: “anthropogenic signals are not yet clearly detectable in observations for most TC (tropical cyclones) metrics.”

A study by a NOAA Hurricane Researcher Chris Landsea found that using 1940s observational methods “only 2 of these [recent] 10 Category 5s would have been recorded as Cat 5 if they had occurred during the late-1940s period.” 

Hurricane Maria, which hit Puerto Rico in 2017, was not an unprecedented storm, with the eighth-lowest landfall pressure (917 mb) on record in the Atlantic Basin. Meteorologist Anthony Watts noted, “With Irma ranked 7th, and Harvey ranked 18th, it’s going to be tough for climate alarmists to try connecting these two storms to being driven by CO2/global warming. But they’ll do it anyway.”
