To this point, they haven’t proposed a single law/agreement/policy that will affect future climate (unless you consider a few hundredths of a degree significant).
Whether eco-fanatics want to talk about the Copenhagen proposal, the Paris agreement, international discussions between or before those, Obama’s EPA policies, California’s actions and proposals, or anything else, nothing has even been talked about that would decrease future temperature by more than thermometer reading errors. Bill Nye’s “100% renewable by 2050” would make a difference. But nobody is telling us how they plan to get there and nobody is talking legislation/agreements/policy to do anything close to that.
Instead of changing temperatures, the proposals
* redistribute money (from wealthy to governments, bankers, “green technology” fraudsters, and developing nations)
* limit growth of developed nations
* stop development of developing nations
* make environmentalists feel good
There are NO proposals that come close to their stated goals. Supporters are either extremely stupid or are hiding their true agenda or both.
Historically, CO2 spikes came after temperature spikes, nothing we can do will be effective. 100% renewable, if it is anything like current electric cars or ethanol, actually cause more CO2 output in total than the fuels they replace.
