OldSalt posted:I also meant to say, but was battling trying to post from my iPhone, indeed climate varies naturally due to solar cycles, the nature of the earth’s orbit and axial tilt and other factors. But taking only those into consideration the earth should be in a cooling trend. But it’s not. The current warming trend parallels the CO2 concentration in the atmosphere. I’ve always questioned what comes first - higher temperature resulting in more plant material decay leading to more atmospheric CO2 or more CO2 resulting in higher temperature.
Ice cores show that CO2 lags temperatures, so warmists propose that gas molecules have little boring machines so that they move upwards. As to the Holocene, depending on who one listens to, we could be near the end or we could have another 10K years.
