The longer the U.S. holds off action to mitigate climate change, the more costly the effort will become, a new report shows

A new report estimates the cost of mitigating the effects of climate change could rise by as much as 40% if action to reduce greenhouse gas emissions is delayed 10 years – immediately outweighing any potential savings of a delay.

The White House’s Council of Economic Advisers, U.S. President Barack Obama’s source for advice on economic policy, compared over 100 actions on climate change laid out in 16 studies to extract the average cost of delayed efforts. Released Tuesday, the findings suggests policymakers should immediately confront carbon emissions as a form of ‘climate insurance.”

‘Events such as the rapid melting of ice sheets and the consequent increase of global sea levels, or temperature increases on the higher end of the range of scientific uncertainty, could pose such severe economic consequences as reasonably to be thought of as climate catastrophes,” the report reads. ‘Confronting the possibility of climate catastrophes means taking prudent steps now to reduce the future chances of the most severe consequences of climate change.”

The report also found that any increase in climate change amid that delayed action would gravely […]
