Still no new science (is there any? Jules and James didn’t find much to post about at EGU), but Tamino posted on AF, which prompted me to look up some of my earlier posts. Tamino shows the CO2 growth rate from 1960, and they look upwards, which was rather less obvious when I drew them from 1990 on.
If you want to think happy thoughts, you can notice that the dCO2 rates are ~a bit less than 2 ppm on average, which is to say rather closer to 0.5% than 1% (1% gets you CO2 doubling in 70 years; but even 0.5% will get us above 600 ppm by the end of this century).
Update: this is an experiment (in two senses). Firstly, can I make a paypal “donate” button? And secondly, will anyone use it ;-? Don’t worry, I won’t be offended if you don’t.
