*IPCC and the Green idea plans are based on the assumption that greenhouse gases can be removed from the atmosphere. That technology does not exist to scale needed at this time for obvious reasons of energy and land requirements. Paleoclimate records easily show us that you aren't going to simply stop global warming at +1.5-2 C by ending emissions (the current carbon dioxide equivalent concentration is 500 parts of million; 1700s concentration was ~275-280 ppm, even with other greenhouse gases). The 1.5 C report last autumn suggested another 0.6 C of warming was locked in based on recent emissions and we must be net zero carbon by 2050; but this is based purely on emissions from *humans*, removal of carbon on scales of hundreds of gigatons (basically removing what took plants tens of millions of years to sequester...bind as solid matter via plant growth...in *tens of years*...really? With what energy source...what land?) and fast feedback sensitivity. Water vapor...loss of sea ice and albedo...some effects from clouds...other feedbacks which are clearly showing an exponential behavior are simply neglected in models. Even the feedbacks which are easily seen and more quantifiable are accelerating much faster than expected. The Permafrost is melting fast, methane is spewing, the oceans are getting warmer, the circulation in the atmosphere has changed. Are we on the road to extinction? Now that is a happy thought isn't it. Our grand babies might be doomed.*
