You really need to start reading my posts...I've lost count of how many times I've linked the
included NOAA article on CO2 atmospheric concentrations.
Every Physicist understands and accepts "Global Warming" as the result of humans burning Fossil Fuels. Climate scientists also understand the influence of Milankovitch Cycles...which I've also previously posted. Together they explain why global temperatures are rising...at an accelerating rate...when we should be starting a global Cooling Period.
Please read this link, and especially focus on the chart of CO2 atmospheric concentration over the past 800,000 yrs...hopefully that will resolve your query...if not get back to me and I'll try to find another way.
