The natural variation that has led us out of the Little Ice Age has a bit of frosting on the cake by land use; and, part of that land use has resulted in a change in vegetation and soil CO2 loss so that we see a rise in CO2 and the CO2 continues to rise without a temperature accompaniment (piano player went to take a leak), as the land use has all but gobbled up most of the arable land North of 30N and we are starting to see low till farming and some soil conservation just beginning when the soil will again take up the CO2, and the GMO's will increase yields, then CO2 will start coming down on its own and we can go to bed listening to Ave Maria to address another global crisis to get the populous all scared begging governments to tell us much ado about... nothing.
