Then why build levees? Why build storm drains?Humans cannot control weather or natural disasters.
We can and we plainly do. We have deforested vast tracts, we have concreted and paved over huge amounts of land causing local heating in our environments and we have measurably changed the chemistry of the atmosphere and the oceans and not just a little bit.No, I do not think we should be as arrogant enough to think we can reverse the natural order of the world.
The people of Easter Island didn't think they could destroy their environment either but they were utterly wrong. Species are going extinct because we hunt them or destroy their habitat. We can and DO overturn the natural order - with great carelessness and disregard.
That was not the settled science. Yes, the earth is due for an ice age under normal circumstances (we should be in the slide which will last a few thousand years if we hadn't intervened, but we did and we have changed the natural course - we have known since the late 1800s what greenhouse gasses do and sure enough - they still do it. THAT is settled science. The Milankovitch cycle is also settled science, and we can see which of these is winning.In the 70s the "settled science" was we should have dusted the polar icecaps with black coal dust to melt the ice caps and stave off the impending ice age.
What we need to do is ... stop doing what we are currently doing. That is not such a great reach because we can replace all fossil carbon source fuel with other energy sources that DON'T release new carbon into the air. We understand nuclear if we need that much energy, but we can access wind and solar etc as well, and we also know how to make cars that use far less energy over their lifetimes, and we know how to build houses that use far less energy over their life times and we don't need a new phone every year and we don't need and endless supply of plastic do-hickies and we don't need to run our airconditioners to arctic temperatures, and we CAN save for the future because if we want to live it all now, we can but then we're dead... and so are our kids.Under current technology there is no way we'd have the energy, let alone the understand, to make any positive impact. We probably will never have the energy required, as it would be the energy of a star, just like light speed travel.
Analogy - if mine is straw then so is yours - which was the point of the analogy.Strawman.
Green technologies are currently viable, more will become rapidly viable with investment, and all of them need to be developed NOW while we still have other energy we can use to get the job done. If we come to a hard stop with fossil fuels we cannot develop the alternatives. That stop will happen one day and it will be particularly hard if we don't prepare for the switch over - and if we prepare for the switch over then your totalitarian fear will have a hard time taking hold - but if we don't prepare for a necessary change over - even if AGW was not real, then we will be plunged into the grip of a very strict regime or we will take our chances in the chaos as civilisation crumbles.I've said a thousand times I have no issue with "green" technologies, as long as they are viable. LED lighting is approaching that viability, or it is already here in many applications. Wind mills? No, they do little more than kill birds and decimate natural habitats of countless species. Advancing "green" technologies in and of itself is not the problem. The problem is that's not the goal of the AGW cult. That goal is Global Communism and total control of the populace.
