ice cores, which show several cycles over the last 750,000 years, each one lasting around 120,000 years. Carbon dioxide levels and methane levels are
high during the warm periods and low during the cold periods. The main driver behind these changes are variations in the Earth's orbit, and
these would suggest that we should now be heading towards a very slow cooling."
perfect! total ambiguity.... hey, summer is coming so don't expect snow in july! so what if it was the warmest march in 150 years? that isn't long
enough to matter in the scheme of things...
