From the article:

Their research has not yet been peer reviewed, but the authors found that even using what they describe as a “narrow accounting” method — looking only at climate impacts from heat and extreme weather on household budgets and mortality — there were “sizable costs to U.S. households from recent climate change patterns.” Those started at $400 per year and went as high as $900 depending on how extreme weather were attributed to climate change, adding up to an aggregate cost of about $50 billion to $110 billion nationwide.

Sorry about the hard paywall; there is no other coverage yet.

The working paper that the article is about is open-access
