Few of us will ever venture past the 60-mile boundary that separates Earth and outer space. If you do, though, you're likely to experience something known as "the overview effect" -- a cognitive shift in how you perceive our planet.

The Sierra Club is joining and expanding this successful effort to convince even more companies to get on board and go even further to reduce their oil consumption altogether. To date, the climate movement has largely given large corporate oil consumers a free pass. Those days are over.

Dozens of fracking waste injection-caused earthquakes have occurred in Faulkner County, with 12 small quakes in a five-day period back in October 2010, another ten quakes in a single day in November 2010 and a sizeable 4.7 magnitude quake shaking things up in February 2011.

If infrastructure, such as the Keystone XL pipeline, is built to transport tar sands, ways will be developed to extract more and more. When full accounting is done of emissions from tar sands oil, its use is equivalent to burning coal to power your automobile.

TransCanada, the multinational corporation hoping to build the controversial northern half of the Keystone XL pipeline, spent over $280,000 on lobbying the U.S. government in the first quarter (Q1) of 2013, according to lobbying disclosure records.

Questions include what exactly caused the spill, how big was the spill exactly, and how long did it take for emergency responders to react to the spill, to name a few. But one thing is certain according to the new study: For the residents of Mayflower, quality of life has been changed forever.

Raymond Ladouceur remembers when he could dip a cup into the Athabasca River for a drink. He remembers when the trout and muskrats were plentiful -- a...

The only way to do that is to drop Big Oil and petro states once and for all. And the only way to do that is to get serious about green energy which Nocera treats like a punch line. I wonder if they are laughing in Iowa now that they are getting 25 percent of their electricity from wind?

If you love the Earth, you need to know some things about tar sands crude -- starting with how it would affect the climate of this wonderful planet we all share. Actually, "affect" is probably the wrong word. We're talking wholesale destruction.

It's not in our national interest. It's a profit scheme for big oil. It would feed our addiction to fossil fuels, accelerate climate change and put our heartland farmers, ranchers and communities at risk. It needs to be denied.

What caused the disaster in Mayflower is under investigation, and it's unknown how long Exxon's Pegasus pipeline will be shut down. It's also unclear how long cleanup operations will take. Some locals fear the impacts will be long term.

Debra White Plume and Marie Brush Breaker Randall stood in the middle of Highway 44, alongside more than 70 other members of the Oglala Lakota Nation....

Now, our team here at 350.org is hoping to spark a new wave of not just concern, but action, with a new documentary called Do the Math about the growing movement to take on the fossil fuel industry.

O'Brien's has had its hands in the botched clean-up efforts of almost every high-profile oil spill disaster in recent U.S. history, including the Exxon Valdez spill, the BP Deepwater Horizon spill, the Enbridge tar sands pipeline spill into the Kalamazoo River, and Hurricane Sandy.

A thunderstorm is supposed to hit Mayflower with up to 1.7 inches of rain. The lakes and streams will flood and the land will be washed over, not with life giving spring rain but with tar sands oil. I am scared for my friends and for a place that for four years was my home.

No wonder ExxonMobil is doing everything it can to keep reporters and everyone else as far away from the Mayflower disaster as possible. The more the American public learns about the real cost of tar sands crude, the more opposition to the Keystone XL will increase.

Sherry Appleman awoke abruptly in the middle of the night less than 48 hours after a pipeline rupture last month sent thousands of barrels of heavy cr...

In other words, the gas industry isn't joking about its desires to export shale gas to the global market, despite paying homage to the necessity to frack for "national security" and domestic energy purposes.

Tar sands expansion rewards the oil industry while putting us all at risk of oil spills and climate change. That's a raw deal by any calculation.

To understand the hydro-fracking bubble, there are some things one must know: each well only produces a little gas, reserves were significantly overstated at the beginning of the game, and most important: Wall Street is very invested and wants its money out.

Officials at TransCanada insist that their proposed Keystone XL pipeline is environmentally safe. Current events suggest otherwise.

If President Obama rejects the permit for the Keystone XL pipeline, Big Oil executives are likely to look back at last weekend's tar sands spill in Mayflower, Arkansas as a key reason for their defeat.

When will news media be allowed back into the designated no fly zone area? That portion of the question was either never asked by Dow Jones or never answered by Lunsford.

Throughout its history, ERM has proven instrumental in the fossil fuel industry's deployment of the "Tobacco Playbook," magically transforming one-sided scientific debates like climate change and ecological impacts of extreme pipeline proposals into faux two-sided disputes.
