Obama said today in his speech on fuel standards that for decades unchecked carbon pollution was having severe impacts on our weather:
So for decades the fuel efficiency standards of our cars and trucks had been stuck in neutral, even as other kinds of technology leapt forward. And that left families and businesses in our economy vulnerable to fluctuations in oil prices.
Every time oil prices shot up, the economy got hurt. Our automakers were in danger of being left in the dust by foreign automakers.
Carbon pollution was going unchecked, which was having severe impacts on our weather.
