What has triggered the sudden increase in CO2 from baseline over the last hundred or so years then? And there’s no sign of it leveling off. In theory a warmer atmosphere from more trapped heat can hold more water too…hence the higher dewpoint levels.
But you have been a fan of the sediment and ice core data in the past and they have ways to determine the annual CO2 from those layers. Like the graph I posted earlier shows, it’s pretty much ranged from 200-300ppm over the last 800k years. So 425ppm and steadily climbing isn’t normal variation…at least it isn’t to my eyes.
Nice on the coop door. I’ve been wanting one, but I’m always afraid something will fail and it will open up at night. My birds are molting hard right now. Big winter incoming? I got them all winterized yesterday.
