Re “U.S. Climate Study Has Grim Warnings of Economic Risks” (front page, Nov. 24):

We have been warned. If the status quo continues, the ravages of climate change will be devastating. Tens of thousands of Americans will die prematurely and the economic costs will weaken the country, according to the government’s own analysis.

In the first two years of Donald Trump’s presidency, we have disengaged from the global Paris climate accord, and the Environmental Protection Agency, under the president’s direction, has rolled back gains the Obama administration had made in taking measures to reduce the greenhouse gases that are the culprit in this man-made calamity we now face.

Tragically, over the past two years we have lost over 3,000 Americans to violent hurricanes and wildfires , events that are predicted to increase in volatility if we do nothing. The verdict is in. Climate change is here and it is now, Mr. President. You are abdicating your responsibility to protect the citizens and the country that you serve, and it is as befuddling as it is inexcusable.

Perhaps now that the effects of climate change have been presented in dollars and cents, some of those who have the most power to make the needed changes will take some action. I am not very hopeful, however, as short-term gain has almost always eclipsed long-term vision.
