You're right, there is no guarantee of sexual preference, climate change, or just about anything else. When we set off the first atomic bomb many scientist feared a chain reaction would destroyed all life on earth. When JFK blockaded Cuba, there was no guarantee that the Russians would back down. When the American colonist declared independence, England could have certainly smashed the rebellion by diverting it's forces in Europe to the America. There are no guarantees.
So the answer is to throw trillions of dollars into something that will likely not change anything. Sorry, but I think we could use those trillions for better things.
No, I think at this point the money should be going to research as FA_Q2 suggested. The problem is bigger than just limiting greenhouse gas production. Once excessive amounts are in the air, how do we get them out? Also, there are lot of answered questions about climate change.
It seems pretty clear that there is not going to be any global plan to reduce greenhouse gas production. It's going take a lot more than scientists warnings of increases in CO2 or small increases in global atmospheric temperature. People are going to have to experience first hand the results of climate change. Maybe by then there will be technological developments that can help. If not we just adapt.
Eventually we will use cleaner products for energy. I really can't see people going to a gas station in about 100 years from now. But it has to come at it's own time--not be forced on us through taxation or subsidies. If we are going to change, it has to be a benefit that people can immediately see, not something we can't or prove.
Look......we're both older people. We remember way back when this all started. Back then, it was global cooling that was the headline in the news. But since then, look at how much we've done. We have much cleaner burning gasoline, cars that get two to four times the milage they used to get, we got rid of fluorocarbons in our spray cans, lead out of our gasoline and paint, new anti-freeze for our cars, eliminated DDT, use of biodegradable packaging (McDonald's), elimination of asbestos, low sulfur diesel fuel, and the list goes on and on.
So what have our rewards been for these efforts? Things are worse now than ever before according to environmentalists in spite of the huge reduction of our carbon footprint.
