Bull. The end of the Younger Dryas was less than 10,000 years ago, and the temperature rose an average 8-10 C worldwide in a very short period of time. We have several guesses as to the mechanism, but no explanation that everyone accepts.
And of the CO2 we put into the atmosphere as humans, each year half is removed, mostly to the ocean, the rest to living things. Earth is much greener than 80 years ago, to the tune of feeding an extra 1.2 billion due to more CO2 in the atmosphere and the ocean. The remaining billions are due to more efficient agriculture, from many different techniques.
What caused the PETM then? As for what caused the Younger Dryas, I am in the Celestial Event camp. Could have been a Comet, Asteroid or even CME.
Check out the Carbon Cycle and what it is and how it actually works. I am not a Climate Alarmist, far from it. The Climate does change, the question is what are the mechanisms for this change. Is it on a cycle? Are there other factors in play?
Yes, extra Carbon does wonders for plant growth. In fact after the Younger Dryas we hit the Climate Optimum in which temperatures were higher than today. Farming was able to be conducted at higher elevations, 1500 feet higher in fact.
These are all interesting questions in how the Earth works. Why does the planet enter glacial and what causes the interglacial periods?
For you to dismiss my invitation to listen to a real expert on the Carbon Cycle with the simple response..”Bull..” means either you didn’t actually read my post or have been enjoying adult beverages while posting.
I hope it was the latter and that your team is winning in the NBA Finals.
