Environmental Protection Agency (EPA) Administrator Lisa Jackson dismissed GOP calls to delay a critical finding on greenhouse emissions in light of hacked e-mails from climate scientists.

EPA documents released Monday state that greenhouse gases threaten human health a finding that is a precursor to planned regulations controlling emissions from power plants, vehicles and other sources.

Republicans including House Oversight and Government Reform Committee ranking member Darrell Issa (Calif.) said e-mails among climate scientists hacked from a British research institute show holes in the case that humans are causing global warming.

Jackson disagreed.
