The US will never be a leader in what to do with Climate Change the country keeps changing it's mind every 4 to 8 years. Other Countries need to get together and lead, ignoring the US. Even China and India are getting concerned from what I heard. So Sweden is doing the correct thing.
People in the US have a addiction to large gas guzzling Auto worse that the most hard core heron addict. The newest two excuses I hear is 1) They are higher and I can see better. 2) they are larger thus safer. Ignoring the fact with almost everyone is driving the same type auto those two excuses are irrelevant. Nevermind the strangle hold of the established Corporations.
Pres, Carter brought up Climate Change up as a big issue the late 70's and stated if work not started now. it be more difficult going forward. He even installed Solar Panels on the White House. When Regan came in the first thin he did was rip them down and said Carter was nuts. Since then the US have been going around in circles.
