According to a report released June 22 by the Obama administration, doing nothing to rein in greenhouse gas emissions would cost the United States billions of dollars and thousands lives.

The findings come as part of an attempt by the Environmental Protection Agency to quantify the human and economic benefits of cutting emissions in an effort to reduce global warming. The report is the latest piece of President Obama’s recent climate push and provides a tool that he hopes to use in negotiations at the U.N. climate talks in Paris later this year.

The report, which was peer-reviewed, estimates that if nothing is done to curb global warming, by 2100, the U.S. will see an additional 12,000 annual deaths related to extreme temperatures in the 49 cities analyzed for the report. In addition, the report projects an increase of 57,000 premature deaths related to poor air quality, annually. The economic costs would be enormous, as well. By 2100, climate inaction will result in:

  • $4.2 to $7.4 billion in additional road maintenance costs each year.
  • $3.1 billion annually in damages to coastal regions due to sea-level rise and storm surges.
  • $6.6 to $11 billion annually in agricultural damages.
  • A loss of 230,000 to 360,000 acres of cold water fish habitat.
  • A loss of 34 percent of the U.S. oyster supply and 29 percent of the clam supply.
  • $110 billion annually in lost labor due to unsuitable working conditions.

The EPA also used a number of charts to illustrate the difference between taking action to stop (or “mitigate”) climate change and continuing with business as usual (which the charts refer to as the “reference” case.)

For example, if we don’t mitigate climate change, temperatures will continue to skyrocket:

Precipitation levels will become extremely volatile:

Air pollution will become much worse:

And the risk of drought will rise for much of the country:
