American Medical Association: Yes
Scholarly studies: No
This is from a study by Tom Moore:
This study shows that climate change would probably reduce mortality in the United States by about 40,000 per year, assuming a 4.5° warmer climate – the IPCC best estimate of temperature change with a doubling of carbon dioxide. Benefits would extend to lower medical costs nationwide. Measuring willingness to pay by wage rates shows that people prefer warm climates and would be willing to give up between $30 billion and $100 billion annually for a 4.5° increase in temperatures.
