(CNN) - Former Utah. Gov. Jon Huntsman, known for having the most moderate view on climate change in GOP presidential field, suggested Tuesday the verdict was still out on mankind's role in the situation.
"Because there are questions about the validity of the science...I think the onus is on the scientific community to provide more, to help clarify the situation," Huntsman said at the Heritage Foundation, a conservative think tank in Washington, D.C.
Rock Hill, South Carolina (CNN) –Presidential candidate Rick Perry stood by his belief Saturday that manmade global warming is an unproven scientific theory while another White House contender is warning that the mindset puts the Republican Party in a "losing position" in 2012.
Former Utah governor and U.S. Ambassador to China Jon Huntsman, who is trailing top tier candidates in most national polls, openly criticized Perry's position on Twitter this week. He stressed the potential impact on the party in a taped interview that airs Sunday.
Washington (CNN) - A crippling winter storm may be wreaking havoc across the United States, but former Vice President Al Gore says that doesn't mean global warming is debunked.
Gore, an outspoken environmentalist, took to his blog yesterday to post a response to Fox News Channel host Bill O'Reilly, who wondered on his show why much of New York State was covered in snow.
Cancun, Mexico (CNN) – Delegates at the United Nations climate change conference in Cancun, Mexico, approved an agreement early Saturday, despite objections from Bolivia and with praise from the United States government.
On Saturday, the White House said President Barack Obama congratulated Mexican President Felipe Calderon on the conference's conclusion in a phone call.
Washington (CNN) – A rise in skepticism among Americans over global warming is mostly due to changes among Republicans, according to new national poll.
The CNN/Opinion Research Corporation survey, released Monday, indicates that two-thirds of all Americans believe global warming is a proven fact. That's down eight points since June of 2008, with views among Democrats holding steady while Republicans' belief in global warming dropping 11 points.
"The growing skepticism among Republicans, with no matching shift among Democrats, suggests that the changes measured in this poll may be a reaction to having a Democrat in the White House rather than a shift in underlying attitudes toward global warming," says CNN Polling Director Keating Holland.
The poll's release come as a United Nations climate summit opened in Copenhagen, Denmark. That global conference began under a cloud of accusations, after international attention the past two weeks over hacked e-mails that suggest some scientists faked data to support the argument of global warming. But Holland notes that polls released last month from other organizations have found similar shifts in views on global warming for several months. He says that indicates the changes in the new CNN survey are not the direct result of the media attention to the leaked e-mails from climate researchers.
Washington (CNN) – A new national poll indicates that some Americans are cooling to global warming.
According to an ABC News/Washington Post survey released Tuesday - less than two weeks before the start of a global conference on climate change in Copenhagen, Denmark - 72 percent of those polled believe that climate change is happening, down 8 points over the past year.
The poll indicates that the rise in skepticism is mostly due to a shift among Republicans and independents. According to the survey, 54 percent of Republicans questioned believe global warming is happening, down 22 points over the past three-and-a-half years, with a drop of 15 points among independents. The belief in climate change dipped 6 points among Democrats during the same period of time.
The survey's release comes as a Democratic-sponsored "cap-and-trade" proposal to cut pollution slowly makes it way through Congress. The bill calls for the federal government to limit the amount of greenhouse gases that companies can produce in their factories or power plants, and to penalize companies that exceed greenhouse gas limits with fines or by making those businesses pay money to other companies that produce less pollution.
WASHINGTON (CNN) – House Democratic leaders are furiously lobbying their members and moderate Republicans to support a landmark energy bill in the face of resistance from some conservative members of their own party, and staunch opposition from the GOP - roadblocks that are making it difficult to find the 218 votes necessary to pass the measure, according to Democratic leadership aides.
A vote on the Clean Energy and Security Act, which would restrict emissions of green house gases and require use of alternative energy in an effort to slow the effects of global warming, is scheduled for Friday.
The legislation's lead sponsors held a pep rally outside the Capitol on Wednesday to whip up support for the legislation's passage.
"We are going to pass the most important energy and environment bill in history," declared Rep Ed Markey, D-Masachusetts, chairman of the Select Committee on Energy Independence and Global Warming. "We are going to reduce the carbon we send up into the atmosphere but at the same time we are going to begin to back out the oil that we import from countries that we should not be importing it from."
The legislation would require a 17 percent emissions reduction from 2005 levels by 2020, mandate electric utilities to meet 20% of their electricity demand through renewable energy sources by 2020, provide $90 billion for new investments in energy efficiency and renewable energy, along with $60 billion for carbon capture and sequestration. Another key provision, termed "cap-and-trade," would require industries and manufacturers to cut carbon emissions by setting up a system where they could buy and sell pollution credits.
(CNN) – Man-made climate change threatens to stress water resources, challenge crops and livestock, raise sea levels, and adversely affect human health, according to a strongly-worded report from the Obama administration released Tuesday.
The nearly 200-page document on global climate change - released by the White House science adviser and mandated by Congress - does not include new research, but encompasses several recent studies on the effects of global warming over the last half century.
Among the report's key findings are an "unequivocal and primarily human-induced" rise in the earth's temperate of 2 degrees Fahrenheit over the last 50 years, and a projection of more rapidly changing temperatures over the next several decades.
The continuing temperature rise is likely to spur a series of negative consequences for the Earth's energy supply, water, transportation, ecosystems and health, the report also states.
"[The report] tells us why remedial action is needed sooner rather than later, as well as showing why that action must include both global emissions reductions to reduce the extent of climate change and local adaptation measures to reduce the damage from the changes that are no longer avoidable," said John P. Holdren, the White House science adviser.
WASHINGTON (CNN) - A new national poll indicates that a majority of Americans think that global warming is real, and that the federal government can do something to slow or stop the phenomenon.
Fifty-four percent of those questioned in a CNN/Opinion Research Corporation survey released Tuesday say that global warming is occurring and that Washington can take steps to slow the rate of global warming, or eventually stop it altogether. Twenty-seven percent agree that global warming is real, but think the federal government is powerless to stop it or slow it down, and 17 percent say that global warming is not occurring.
"Two-thirds of Democrats think that the government can do something about global warming, but only a third of Republicans feel that way," says CNN Polling Director Keating Holland. "The same number of Republicans don't believe that global warming is happening at all. Only one in 20 Democrats think global warming is a myth."
The poll also suggests that a slight majority oppose a proposal called "cap and trade," which would allow the federal government to limit the emissions from industrial facilities such as power plants and factories that some people believe cause global warming. Companies that exceed the limit could avoid fines or higher taxes by paying money to other companies that produced fewer emissions than allowed. Forty-four percent support "cap and trade," which is backed by the Obama administration.
