We should not take people seriously who doubt global warming as such. Reading thermometers is not rocket science, but perhaps too complicated for some folks.
The scientific issue is about man-made climate change versus natural climate change.
Fission power is a dead end. We should use the existing plants, but not invest in new ones. Far too expensive anyway. Waste disposal is unclear. Uranium supplies are limited.
And we need massive energy savings programs. Germans enjoy the same standard of living using only half the energy per capita of the US. Just replacing inferior US windows with state of the art ones would result in huge savings, both heating and air conditioning. Same for other building insulation approaches.
I’ve said this before: Resisting green technology will hurt the US big time. Same for climate change denial. Here are some of the key messages
1) There is no 100% correct prediction about the climate in 2050 – climate is too complex
2) Human greenhouse gas emissions most likely contribute to global warming
3) It’s quite possible that natural cycles contribute as well
4) A few cold winters or cool summers are no proof against the continuing overall trend
5) The vast majority of reputable climatologists think that the potential harm is enormous
6) Humanity would be very stupid not to apply the precautionary principle
7) The growing middle class in Asia will significantly affect supply and demand equation for fossil fuels – oil sand extraction won’t be able to keep up with this
8) To create welfare for all world citizens we simply have no other choice than to invest in green technology
9) The unfortunate climate change denial movement is most active in the US. This is bad news for the US, but good news for the rest of the world because innovation will happen elsewhere and the US will eventually have to import new green technology products. A nation of consumers instead of producers. Unless reason prevails.
