We seem to be talking at cross purposes here.
Some technologies advocated here, like hydrogen, make no sense. You have to MANUFACTURE hydrogen first and that at present involves lot of CO2 since it’s made from natural gas by extracting the hydrogen and leaving…CO2.
The cleanest way to make hydrogen is to use hydro power or nuclear energy to use electrolysis of water. Neither will likely pass political approval.
Thee is no single silver bullet or magic wand to address climate change. It involves the collective effort of all citizens and the power of science to bend the curve.
Don’t bring this subject up with the average Frenchman. He (she) will point out that France gets 85% of its electricity from non-carbon sources, the average French car only goes 7000 miles per year and gets nearly twice the miles per gallon and most Frenchmen live I apartments, like New Yorkers.
Climate change will involve adaptation as well as mitigation.
I have some neighbors who really believe that the world is going to hell in an handbag but they still drive their 300 hp machines to pick up a quart of milk at the 7/11.
Obama talked a good environmental story but did not have the political guts to enact legislation, European style, to penalize heavy and high horsepower personal vehicles and increase gasoline taxes. Cracking down on industry is more popular because plants don’t vote.
We are, in the eyes of the world, the greatest hypocritical energy gluttons…
Since I have to practice what I preach, our family has reduced energy use in home by 45%, and halved that used in transportation without any change in lifestyle.
When I go to a climate change presentation I casually ask a number of attendees how they got there. So far no one rode a bike, walked or used public transit.
Each one of us has the choice of listening to neutral scientist or politicians. Neutral scientists stick to the subject and don’t exaggerate.
