I believe that this Limits to Growth study is a very good estimation of what is going to happen during the remainder of this century. The updated LTG study simply confirms what most scientists already understand to be the future. Ignore it and make jokes about it if it makes you feel better, but the wheels are in motion, and very little is happening to slow down the train. I would be interested to hear what you think will happen when the oil and natural gas stops flowing (which even all of the big oil companies acknowledge is coming this century). Meanwhile, our big orange felon kindergartener will do everything in his power to stop any progress and take us backwards --- simply speeding up the catastrophe. Drill baby drill, party on!!!
