Increased hurricane activity and other extreme weather events are a result of natural weather patterns, not human-caused climate change.

According to a report from the Tropical Meteorology Project at Colorado State University, the increase in human-produced CO2 over the past century has had “little or no significant effect” on global tropical cyclone activity. The report stated that specific hurricanes, including Sandy, Ivan, Katrina, Rita, Wilma, and Ike, were not a direct consequence of human-caused global warming. [89] Between 1995-2015, increased hurricane activity (including Katrina) was recorded; however, according to the NOAA, this was the result of cyclical tropical cyclone patterns driven primarily by natural ocean currents.

Professor of Earth and Atmospheric Sciences at the Georgia Institute of Technology, Judith Curry, PhD, stated that she was “unconvinced by any of the arguments that I have seen that attributes a single extreme weather event, a cluster of extreme weather events, or statistics of extreme weather events” to human-caused climate change. [90] Experts have noted that many factors beyond climate change are to blame for events such as wildfires, including failed policies on clearing brush, too much population density, and people who set the fires either deliberately or through carelessness.
