NBC exposes the "unspeakable" realities of the Japanese catastrophe in its 60 Minutes program Sunday night during which leading nuclear scientist Dr. Michio Kaku said radiation from Fukushima will impact of all of humanity.

Scientists to study impact of gulf oil spill on marine food webs. Shells from oysters, clams, and periwinkles hold clues about the ways and rates at which harmful compounds from the spill are being incorporated into the Gulf's marine food web. New reports are surfacing every day about the immediate impacts of the Deepwater Horizon oil spill on Gulf Coast wildlife, especially as the oil reaches the sensitive marshlands along the coast. But how will these communities be affected over time? (Source: Science Magazine)

"Scientists reveal the growing atmospheric concentrations of man-made greenhouse gases are driving irreversible and dramatic changes to the way the ocean functions, with potentially dire impacts for hundreds of millions of people across the planet. "

"In 2009, the scientific literature caught up with what top climate scientists have been saying privately for a few years now: * Many of the predicted impacts of human-caused climate change are occurring much faster than anybody expected - particularly ice melt, everywhere you look on the planet. * If we stay anywhere near our current emissions path, we are facing incalculable catastrophes by century's end, including rapid sea level rise, massive wildfires, widespread Dust-Bowlification, large oceanic dead zones, and 9°F warming - much of which could be all but irreversible for centuries. And that's not the worst-case scenario! * The consequences for human health and well being would be extreme. That's no surprise to anybody who has talked to leading climate scientists in recent years, read my book Hell and High Water (or a number of other books), or followed this blog. Still, it is a scientific reality that I don't think more than 2 people in 100 fully grasp, so I'm going to review here the past year in climate science. I'll focus primarily on the peer-reviewed literature, but also look at some major summary reports."

An Exxon Mobil pipeline that runs under the Yellowstone River in Montana ruptured Friday night and leaked for about a half-hour. The New York Times reported that the over 120 residents in the town of Laurel, downstream from the rupture, had to be evacuated because officials feared a possible explosion. Exxon said it had no information on the cause of the incident, which originated from a 12-inch pipeline that runs from Silver Tip to refineries in Billings. The amount of oil that leaked is still being determined. The Billings Gazette reported that the company had dispatched local cleanup teams with absorbent pads to leach up oil from the riverbanks. Exxon's Global Response Team is being sent from Houston. Exxon Mobile said "it deeply regrets this release and is working hard with local emergency authorities to mitigate the impacts of this release on the surrounding communities and to the environment." The company has set up a toll-free hotline to report oil sightings or other concerns. CORRECTION: Previous version of this article incorrectly referred to Laurel as Lauren.
