The Environmental Protection Agency (EPA) is proposing to regulate carbon dixoide and other greenhouse gases as polutants and a significant threat to human health under the Clean Air Act.

The EPA submitted its proposal to the White House Friday. The proposal was previously rejected by the Bush Administration.

The EPA's finding concluded that six greenhouse gases should be considered pollutants under the 1970 act, but does not outline how or what to regulate. If the White House approves the finding, the EPA and lawmakers will begin discussing what and how the regulation would be handled. 

The finding shows potential health impacts from warming include longer and more severe heat waves; increased smog in some areas; dangerous flooding caused by stronger storms; and diseases, including malaria and dengue fever.
