The EPA is enforcing regulations intended to counteract the warming effects of CO2 which they claim are causing warming.
Of course this has something to do with this discussion.
The EPA, like you, has accepted a notion that is not based in science and is very clearly based in and is directing political discourse and action.
The EPA is a part of the Executive Branch, so, yes, this does involve President Obama as his gang of bully boys is enforcing laws that were never passed by Congress and never could be.
This, like the lack of proof for AGW, exists in the real world so it is probably escaping your notice.
