This discusses data from a March 2024 risk assessment analysis. Total average global warming economic cost was running at ~$400 billion/year. Projected annual cost in some number of years is ~$1 trillion.
A risk assessment by Lloyd's Futureset and the Cambridge Center for Risk Studies, Extreme weather leading to food and water shock: How vulnerable is the global economy to extreme weather and food shocks?, estimates ~$5 trillion in loss over 5 years in the event of a major (1 in 50 years) food and water shock caused by extreme weather. In an extreme food and water shock scenario (1 in 1,000 years), the estimated 5 year loss is projected to be ~$17.6 trillion.
As we all know, a trillion here and a trillion there, and pretty soon you're talking about some real money. And lots of misery for affected people. Probably tends of thousands of deaths, but these risk assessments do not consider human deaths or impacts. These risk assessments deal only with economic losses, not human deaths. This global warming thing is starting to heat up figuratively and literally.
