Climate at a Glance: Deaths from Extreme Weather

Climate at a Glance: Deaths from Extreme Weather

 

 

By Heartland Institute

 

Key Takeaways:

  • Extreme weather events are often attributed to climate change, but weather and climate are not the same thing.
  • Real-world data show no significant increase in extreme weather over the past 100 years.
  • Existing data show many extreme weather events have declined significantly during the recent period of modest warming, and deaths from extreme weather events have declined dramatically.

 

Short Summary:

 

Extreme weather events are just that, weather events. Such events are often conflated with climate change but this is a mistake. Weather and climate operate on vastly different timescales.1

 

The Intergovernmental Panel on Climate Change (IPCC) AR6 report, Chapter 11, Weather and Climate Extreme Events in a Changing Climate, concludes that changes in the frequency and intensity of most severe weather events have not been detected nor can they be attributed to human caused climate change.2

 

Real world data shows that there has been no increase in drought, or heatwaves; no increase in flooding; no increase in tropical cyclones and hurricanes; no increase in winter storms; and no increase in thunderstorms or tornadoes, or associated hail, lightning, and extreme winds from thunderstorms.

 

Regardless of weather trends and climate change, human mortality attributable to weather related disasters, including floods, droughts, storms, wildfires, and extreme temperatures has declined by more than 99 percent over the last 100 years. In the 1920s, death related to weather-related disasters averaged approximately 485,000 each year. By 2020 the average number of deaths attributable to extreme weather events had fallen 7,790. (See Figure 1, below)

Studies also show that, because cold temperatures kill more people than hot temperatures, the slight warming we’ve seen over the past century has reduced overall mortality related to extreme temperatures by as much as 166,000 premature deaths from 2000 to 2019.10

 

Claims that climate change is killing more people are refuted by hard data which shows a significant decline in weather and temperature related deaths.
