Don't Relax, America

There are those who are pointing out that greenhouse emissions in the U.S. are down. But, don't relax, America.

There are more greenhouse emissions in the atmosphere than any time in the last 800,000 years. Carbon dioxide concentrations are substantially up since the beginning of the industrial era. 

Still, it is correct -- if we just take the U.S. -- that pollutants have declined by just more than 2 percent since 1990. Unfortunately, we were so high at that time, that our emissions footprint is still three times that of the global average. And, alas, we are starting to slip, again. Emissions increased 1.3 percent in 2022 compared with 2021.
