Tens of thousands of people Sunday showed their opposition to the Keystone XL pipeline as they marched in cold weather to the White House to urge President Obama to reject the $5.3-billion project, which critics say would hurt the environment.

Organizers estimated that roughly 35,000 people from several U.S. states gathered on the National Mall and then marched to Constitution Avenue, up 17th Street and past the White House, and billed it as the largest climate rally in American history.

"All I ever wanted to see was a movement of people to stop climate change and now I've seen it," Politico quoted Bill McKibben, founder of 350.org, as telling the crowd of protesters. "I cannot promise you we're going to win, but I've waited a quarter century to find out if we were gonna fight. And today, at the biggest climate rally by far, by far, by far, in U.S. history – today, I know we're going to fight." more >>

WASHINGTON – A Democratic Senator who supports the widespread implementation of off-shore wind power has stated that issues that naval interests have with off-shore wind power are a "legitimate concern."

Sen. Tom Carper of Delaware said at a Thursday morning event sponsored by the Center for American Progress Action Fund that concerns about off-whore wind turbines have been raised by many professional seamen. "It's a legitimate concern that has been raised in other countries, it's been raised here, it's been raised around the Navy, in merchant-marine, and so forth. And by the Coast Guard, I think they have provided a whole lot of input in so far as location," said Carper.

"The other thing is making sure that whoever is going to be out there making their ways off of our shore in future years that they have the information about the location of these wind mill farms." more >>

During the economic recession in 2009, the Car Allowance Rebates System (CARS), better known as "cash for clunkers," was billed as a way to both stimulate the economy and help the environment by encouraging Americans to trade in their older vehicles for a new, more fuel efficient vehicle. Writing for E Magazine, Jennifer Santisi, a freelance science and environmental writer, concludes, though, that the program did more harm than good for the environment.

Under the program, consumers who traded in an older vehicle were provided a $3,500 or $4,500 voucher toward the purchase of a new vehicle. About 690,000 vehicles were traded in under the program for a total cost of almost $3 billion.

One of the main problems Santisi pointed to was the engines and drive trains had to be destroyed, and could not be recycled, under the program's requirements. Guarding against potential fraud, the government did not want the vehicles that were traded in under the program to find their way back onto the streets. more >>

A major pharmaceutical company has opted to sever ties with a libertarian think tank that provides arguments critical of global warming and the effects of tobacco smoking.

Pfizer Inc., a New York City-based business that boasts of being the world's largest research-based pharmaceutical company, decided to cut financial support from the Heartland Institute.

Sharon Castillo, spokeswoman for Pfizer, told The Christian Post that the decision was implemented earlier this month for multiple reasons. more >>

Climate change is an issue not often talked about at churches, and has been absent during the presidential debates between President Barack Obama and GOP candidate Mitt Romney. An evangelical group is arguing, however, that Christians cannot love God if they do not care for His creation, which the group says is in great peril.

"I understand that there are many important issues that we care about, that I care about – not just the climate crisis. But the climate crisis is one that is particularly urgent, and I believe that as Christians we have a strong moral and spiritual case for caring for and acting on it," Ben Lowe, a spokesman for Young Evangelicals for Climate Action, said in a phone interview with The Christian Post.

His organization, formed in Feb. 2012, presents the climate change issue from a Christian perspective, stating that it is part of their Christian discipleship and witness to promote action on the environmental challenges facing the planet. more >>

Christians concerned that the presidential debates between Barrack Obama and GOP candidate Mitt Romney are not addressing important environmental concerns are stepping up their efforts to be heard as Election Day draws near.

The Young Evangelicals for Climate Action group, a relatively new organization formed in Feb. 2012, gathered outside Hofstra University during the second presidential debate on Oct. 16 to pray for more discussion focused on the growing threat of climate change. The group says that its mission is to take action against what it sees as an upcoming climate crisis, a calling which is part of their Christian discipleship and witness.

Ben Lowe, a spokesman for the group, has called climate change "one of the biggest global challenges facing my generation" in a piece published by E&E News. more >>
