Way back in the 1870s — when global temperature were supposedly ideal — approximately 50 million people died globally related to extreme weather, particularly related to an extreme El Nino event of 1877-88.
The 1870s also saw the Great Midwest Wildfires of 1871 which killed as many as 2,400 people, the massive 1872 Baltic Sea flood, a 1875 midwestern locust swam of an estimated 12.5 trillion locusts, the 1878 China typhoon that killed as many as 100,000 people, and the U.S. experienced 6 landfalling major hurricanes in the 1870s, compared to just 3 in the 2010s.
It is not widely appreciated, but 2025 (still with two months to go), is currently on track for the lowest global death toll from extreme weather in all of human history. Part of that is good fortune to be sure — for instance, the Northern Hemisphere is well below average in terms of tropical cyclone activity.
