"The Obama administration is likely to rely mostly on existing rules and on flexing executive power to execute its second-term environmental agenda, sidestepping Congress as it sets about radically reducing greenhouse gases generated by major polluters."

"Promoting a recent poll, CNN is treating climate change as a matter of opinion, saying Americans are divided over whether or not it is real. But the network itself has fueled such confusion, often failing to report that manmade emissions are driving climate change or giving credence to those who deny the science behind it."

"More than half the Senate on Wednesday urged quick approval of the Keystone XL oil pipeline, ramping up pressure on President Barack Obama to move ahead with the project just days after he promised in his inaugural address to respond vigorously to the threat of climate change."

"The entire future of Shell's drilling plans in the Arctic was put in doubt on Friday after two of Barack Obama's most trusted advisers called for a permanent halt to oil exploration."

"Of all the Idle No More protests that sprung up on Wednesday's national day of action across Canada, what may have worried the conservative government of Stephen Harper the most was a gathering of aboriginal young men banging tribal drums outside a hotel in downtown Vancouver."

"As America wakes up to the dangers ahead, the president has a historic opportunity to take bold action on global warming."

"Barack Obama's top adviser on oil drilling and the management of America's last wide open spaces announced on Wednesday that he would leave the cabinet by March. The departure of Ken Salazar as interior secretary leaves Obama with virtually a clean slate to remake his energy and environmental team."
