Seems like climate change is well understood:
*1824 Joseph Fourrier (sp?) explains the greenhouse effect
*1864 John Tyndall isolates CO2 as 'the' greenhouse gas in Earth's atmosphere
*1898 Arrhenias Svante is able to predict global warming from CO2 atmospheric concentration.
*1950s David Keeling's CO2 curve,from Mauna Loa ,measurements is verified by other researchers' proxy data.
*Antropogenic CO2 is rising at a nonlinear,geometric rate.(Isotopic assay verifies that this carbon is 'ancient' carbon,dug from the ground)
--------------------------------------------------------------------------
*Venus is 30,000,000 miles further from the Sun than Mercury,and yet,it is 500F warmer.(it has a CO2 atmosphere)
*Earth's MOON,with no atmosphere,averages -100F.
*Earth,at the same distance from the Sun has averaged 56F,with a small compliment of greenhouse gases until recently.Now we're over 57F.
*We've already warmed 1.5 degrees since the Industrial Revolution began.
*If we turn off coal-fired power plants today,we'll gain another immediate 1.5-degrees due to the stratospheric albedo loss from settling Sulfate aerosols now suspended up there.
