US Co2 level dropping to 1991 level

The US has made stunning progress by reducing Co2 emissions to the level of 1991 despite population and economic growth.

The US "arrogantly refused" to confirm the Kyoto protocol under President Clinton and continued to refuse international agreements under President Bush.

But the US kept making progress. The climb leveled off in 2001. Then grew little. Then dropped after shale gas arrived the past 5 years.

Watts up with That
