Here’s a quick thought, and I’ll have to check around how much it has already been vetted:

Most discussions I see regarding government action on climate change imply that EPA would do the acting. Either new legislation would prompt the action, or, as the Massachusetts v. EPA opinion stated, EPA could act under the Clean Air Act.

But is EPA the best agency to take on climate change.  Might it be NOAA (National Oceanic and Atmospheric Administration)?

I realize that agencies’ perogatives veer from the semantic suggestions of their names; but, for a moment anyway this morning, I got to thinking that climate change is a global, atmospheric issue, while statutes have generally charged EPA to protect environments threatened by direct threats to the realms after which EPA named its major offices, like Water and Air; or the mediums of particular pollutants.

The answer to this quiery may rely upon which agency better understands the carbon cycle, etc.  Or, it may make sense to put an agency better positioned to understand commercial issues along with the scientific (NOAA is housed in Dept of Commerce).

Will report back after looking into the thought.
