*The carbon-dioxide cycle between the atmosphere and the ocean.*

From Robert Whitcomb's "Digital Diary'' in GoLocal24.com.

Not unexpectedly, President Trump is pushing to roll back Obama administration rules requiring that cars run at 54.4 miles a gallon of fuel by 2025, up from 27.5 miles a gallon. That is projected to reduce greenhouse-gas emissions by 6 billion tons over the lifetime of new vehicles and save 2 million gallons of oil a day by 2025. Thus the Obama rules would be good for the environment and good for national security by reducing our need for oil, much of which still comes from nasty places abroad.

Car company senior executives always say that they can’t meet new fuel standards but because of always developing technology they always do. In so doing, they’re making more efficient, better-engineered cars. But they’ll take the easy way out if they can to maximize their short-term profits. Senior execs rarely hold their jobs for more than five years so why should they worry much about bad PR about the long-term environment? Their children and grandchildren can fret about global warming.

But global warming aside, what about cleaner air?

Meanwhile such nasties associated with global warming as acidification of the oceans and the consequent death of coral reefs goes on.
