Despite the claims of climate activists and the mainstream media that climate change is causing more tropical cyclones and major hurricanes to form and making hurricane seasons worse, a recent study indicates these claims are false.
In fact, the study shows tropical cyclones have declined 13 percent over the past century. [bold, links added]
A June 2022 study titled Declining tropical cyclone frequency under global warming, published in the prestigious science journal Nature reveals that counts of both northern and southern hemisphere tropical cyclones, which include hurricanes, typhoons, and tropical storms, have declined as the Earth modestly warmed over the past century.
From 1900 to 2012, the study’s authors found that the annual number of tropical cyclones declined by about 13 percent compared with the period between 1850 and 1900 when tropical storms were increasing.
As illustrated in the figure below, which shows the tropical cyclone trend calculated by the researchers using a combination of actual observations and historical reconstructions, the trend after 1900 is clearly downward.
The tropical cyclone trend is almost the opposite of the global temperature trend.
NASA reports the average global temperature went down from 1880 to 1910, only to then increase by approximately 1.0 degrees Celsius (1.8 degrees Fahrenheit) between 1910 and 2012.
Tropical cyclone numbers actually declined more sharply after 1950, by about 23 percent, compared to the 1850-1900 baseline, even as global warming increased during the second half of the 20th century.
Although the study authors noted a variation from one ocean basin to another, all basins demonstrated a declining trend in tropical cyclones.
Contrary to the popular media narrative that climate change is causing an increase in the number and severity of damaging hurricanes, such as Hurricane Harvey in 2017, Hurricane Sandy in 2012, or Hurricane Katrina in 2005, this study shows these claims to be false.
You might say it blows climate alarmists’ claims about hurricanes right out of the water.

All the major Hurricanes we have has since Katrina in 2005 were blamed on Global Warming/Climate Change by the lie a day M.S. Media while Americans lose their trust of the M.S. Media gutter dwellers
They also lie about tornados, drought, floods, cold weather, hot weather, and wildfires. None of these events are significant indications of trends. Comparing one year to the next is misleading since there are so many individual factors possible. Now, trends over longer periods of time, hundreds of years or longer, can tell an interesting story but it rarely supports the story the alarmists want to sell.
