I will believe the science is settled when the journals that carry articles about climate stop rejecting articles that are not "in line" with the alleged settled science, especially those articles that are brought forward by scientists who don't put the word "climate" in front of "scientist" or "researcher" when they describe themselves.
"Science" is about exploring boundaries and ideas, and a "memory hole" has no place at all in science. "Science" is about evaluating the data and resulting theories, not the person bringing the data and theories forward. "Science" is about recognizing new facts and incorporating them into existing theories...or throwing out the old theories when the new facts require those theories to be stretched all out of shape to shoehorn in the new facts, much like politicians gerrymander the boundaries of voting districts to achieve a desired result.
Why have the various predictions been so drastically wrong? That says the science is not settled. If it were, the results would better match the predictions. Especially the doomsday predictions. Not to mention the flip-flops between "global warming" and "global cooling" -- how does the settled science square with those changes in view? I'm reminded of the boy crying "Wolf!"...
I agree that there are trends in temperature change that needs to be watched closely, but I disagree that there is one "magic" solution. Indeed, I look at reduced industrial CO2 emissions as only one of many things we should look to do. For example, have you considered growing grass on the roof of your house, and on the body of your car? How about roofing over car parks, and growing plants on them? Have you looked into dense, CO2-consuming flora on the top of your office building? How many trees have you planted on your property, especially large-leaf ones?
"Climate change" is not a "Someone else's problem" -- it's YOUR problem, too. Why do I see lots of talk but little personal action? Show us how to solve the problem, don't just say "you do it."
