As we know, AGW is the Enviro-mentalists Mad Uncle and has been locked up in the attic for a while now. He was used to scare the kiddie-winkies into believing anything and was so effective, a proxy was introduced - Climate Change - which was just as good at scaring thanks to the memory of the Mad Uncle but was far more flexible and needed fewer excuses for when reality did not match the myth. Of course, we have had a changing climate throughout Human history, but such details do not get in the way of rabid religions intent on subjugation, power and control, and that is what Governments, NGOs and flat-earthers covet and crave. It is therefore no surprise that such bodies have seized upon the Mad Uncle and then the proxy with such relish*.
Al Gore is going to have to make the biggest apology in history. I also want to see all those talking heads, all those government ministers line up and apologise, too. No regret - that is a Japanese mumble-swerve face-saving technique to avoid taking responsibility and admitting an error - but an apology and resignation. I suspect that there is going to be an army of people who will soon realise they have been taken for a ride. Suckered in. They will look back on their public pronouncements and realise they have humiliated themselves. The problem is with this digital age, all those statements now exist and can never be eliminated. Youtube and other such sites will be a place where the blatherings can resurface to haunt.
What is worse is that the kids will cotton on and there will be blood. Will they ever believe adults again? I hope the learn that this is a lie caused by vested interests, by those wishing to forcibly collectivise. You should know who they are.
Do we need to prepare for Climate Change? Hell yes we do. Rivers and coastlines. Floods, water supplies, power, navigation, insulation and most of all food production. We need to determine what might well happen and use risk, timeframe and probability-weighting to prioritise our activities. This needs to be addressed first before we ponce about with trying to "reverse" it, which is, frankly, impossible until India and China (and probably Brazil too) adopts technology not even established.
*If you notice, most if not all the attempts to "control" or "reverse" Climate Change involves forcing people to hand over money, freedom or regress to some antediluvian existence. Preferably all three. The amount of rent-seeking in the sector is colossal.
