Exposure to specific bacteria in the environment, already believed to have antidepressant qualities, could increase learning behavior

"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."

ScienceDaily (Jan. 13, 2011) - The magnitude of climate change during Earth's deep past suggests that future temperatures may eventually rise far more than projected if society continues its pace of emitting greenhouse gases, a new analysis concludes.

How can architects build a new world of sustainable beauty? By learning from nature. At TEDSalon in London, Michael Pawlyn describes three habits of nature that could transform architecture and society: radical resource efficiency, closed loops, and drawing energy from the sun.

"This legislation would undo decades of public land protections by opening up an area the size of Wyoming to new industrial activity. It would allow some of the country's most pristine and spectacular landscapes to be exploited, including the vast majority of undisturbed national forests. "Mining, logging and drilling are already permitted in more than half of our national forests and other public lands. This bill would open the door to such activity on most of the rest. As a result, valuable fish and wildlife could be lost and clean drinking water for millions of Americans compromised. "This legislation would undo the nation's tradition of managing these lands with a balanced approach. It would also disregard years of work by lawmakers from both parties to craft proposals with diverse stakeholders to safeguard these undeveloped areas. In addition, the bill would eliminate interim protections on wild places that people use and enjoy. We urge Members of Congress to oppose H.R. 1581."

ScienceDaily (July 18, 2011) - Researchers from Texas A&M University have returned from a trip to examine the scope and size of this year's "dead zone" in the Gulf of Mexico and have measured it currently to be about 3,300 square miles, or roughly the size of Delaware and Rhode Island combined, but some researchers anticipate it becoming much larger.

Shell's plan to drill four exploratory oil wells off Alaska could invite disaster in the event of a spill.

I was honored to be invited to speak at Occupy Wall Street on Thursday night. Since amplification is (disgracefully) banned, and everything I said had to be repeated by hundreds of people so others could hear (a.k.a. "the human microphone"), what I actually said at Liberty Plaza had to be very short. With that in mind, here is the longer, uncut version of the speech.

"In just a few short months, we've witnessed people power in action. From the Middle East to the Midwest, movements have risen up to overturn tired dogma and challenge entrenched power. Many of us were inspired by these events. And many of us were surprised. Perhaps we were growing skeptical that people power could still work. Maybe we had forgotten a vital fact about our world: that bold citizens, united around a common mission, can still come together to create major change against enormous odds." - 350.org (April 7, 2011) "Even when people are willing to take action in concert to redistribute the pie, whether by Gandhian mobilization or use of force, this may resonate falsely, for the pie is disintegrating. Its recipe and ingredients are obsolete. And freedom attained in harsh austerity, characterized by intense competition for food, will be doubtful or of little comfort." - Jan Lundberg ("Social Justice Activists Must Take Into Account Ecological, Cultural, and Economic Transformation")

Millions of tonnes of plastic debris dumped each year in the world's oceans could pose a lethal threat to whales, according to a scientific assessment to be presented at a key international whaling forum this week. A review of research literature from the last two decades reveals hundreds of cases in which cetaceans - an order including 80-odd species of whales, dolphins and porpoises - have been sickened or killed by marine litter. Entanglement in plastic bags and fishing gear have long been identified as a threat to sea birds, turtles and smaller cetaceans. For large ocean-dwelling mammals, however, ingestion of such refuse is also emerging as a serious cause of disability and death, experts say. Grisly examples abound.
