Breaking all the wrong records in the climate change fight:
Scientific instruments atop the Mauna Loa volcano in Hawaii showed that levels of carbon dioxide in the air averaged 419 parts per million in May, the annual peak, according to two separate analyses from the Scripps Institution of Oceanography and the National Oceanic and Atmospheric Administration.
Those readings are about half a percent higher than the previous high of 417 parts per million, set in May 2020. Carbon dioxide is the most important greenhouse gas driving global warming and researchers have estimated that there hasn’t been this much of it in the atmosphere for millions of years.
I think it was 11 years ago when I attended a climate change summit hosted by NC WARN, featuring former NASA scientist James Hansen. At that time, atmospheric carbon was about 378 parts per million, and Hansen was adamant that we must keep it from passing the 400 mark. That was a tipping point that would very likely trigger the dissolving and subsequent release of methane hydrates in the permafrost and ocean floor. That is no longer a theory, it is happening right now:
