Glogal Warming?






















Long-term change in global tropical cyclone frequency. (Geophysical Research Letters)
In contrast to talk about climate change spawning more hurricanes — that more hurricane strikes will be the “new normal” — the actual global count of tropical storms and hurricanes decreased in their study from an average of 83 during the last 30 years of the 19th century to 59.6 during the last 30 years of the 21st century.
We can conclude, then, that science tells us three things about climate and hurricanes:
  • There is no discernible effect on present activity by climate change
  • There will probably be fewer hurricanes in a warmer world
  • The very strongest storms may get a bit stronger in a warmer world
