Looks like April will be the first month on record averaging 410 parts per million volume (ppmv) of carbon dioxide or above in the atmosphere. We have maybe 4-6 weeks before the yearly plant growth cycle in the Northern Hemisphere pulls the concentration down a few points. We have maybe a year or two before the increases due to fossil fuel use, et al, keeps the average above 410 all year round.
“How much and how soon and under how much warming pressure is still a matter of some debate in the sciences. But the situation is now looking a bit worse for the Totten Glacier — an enormous sea-fronting slab of ice as big as France that if it melted in total would, by itself, raise sea levels by about 10-13 feet globally.”
