Any correlation between CO2 & Temperature ?
Yes but it is a “following” indicator of temperature change. There is a lot more involved. We are at the relatively cold point that we have because of a combination of the Indian Ocean currents that bring the Monsoon rains over India and South Asia and the massive CO2 sink that the Himalayam are after the plate collision that formed them exposed sedimentary and volcanic rock.
However only a political solution will keep us from destroying our economy and ourselves as we think that without immediate action the earth will be turned into an unlivable desert of near boiling temperatures. This article seemed to point a way to clean up after ourselves (always a good idea) without such drastic extremes that are likely with the greens ruling.
