The number of people in the United States who say they don't believe in global warming rose by 7 percent last year, a new study shows.
The data from Yale University and George Mason, compiled between March and December, found 23 percent of people don't think climate change is happening.
Out of those surveyed, a majority — 63 percent — said global warming is occurring, while 47 percent said human activities are to blame.
But fewer than half think global warming will harm them at all, though 65 percent believe it will harm future generations.
The report came out Thursday, the same day that President Obama's new climate regulations came under attack.
While top administration officials were questioned by Republican's about the soundness of the proposed carbon emissions rule for coal-fired power plants, Sen.

McConnell filed a resolution of disapproval under the Congressional Review Act to force a vote that would stop the regulation in its tracks.
The rule would require new coal-fired power plants to include carbon capture systems to cut back on emissions — a crucial piece of Obama's climate agenda and second-term legacy.
