ScienceDaily (June 29, 2010) - A new study shows the Arctic climate system may be more sensitive to greenhouse warming than previously thought, and that current levels of Earth's atmospheric carbon dioxide may be high enough to bring about significant, irreversible shifts in Arctic ecosystems.

ScienceDaily (July 4, 2011) - After evaluating twin pairs in which at least one child has autism or autism spectrum disorder (ASD), researchers suggest that the shared environment may play a more substantial role in development of the condition than shared genes do, according to a report published Online First by Archives of General Psychiatry, one of the JAMA/Archives journals.

Scientists have become increasingly worried that even extremely low levels of some environmental contaminants may have significant damaging effects on our bodies-and that fetuses are particularly vulnerable to such assaults. Some of the chemicals that are all around us have the ability to interfere with our endocrine systems, which regulate the hormones that control our weight, our biorhythms and our reproduction. Synthetic hormones are used clinically to prevent pregnancy, control insulin levels in diabetics, compensate for a deficient thyroid gland and alleviate menopausal symptoms. You wouldn't think of taking these drugs without a prescription, but we unwittingly do something similar every day.  An increasing number of clinicians and scientists are becoming convinced that these chemical exposures con­tribute to obesity, endometriosis, diabetes, autism, allergies, cancer and other diseases. Laboratory studies-mainly in mice but sometimes in human sub­jects-­have demonstrated that low levels of endocrine-disrupting chemicals in­duce subtle changes in the developing fetus that have profound health effects in adulthood and even on subsequent generations. The chemicals an expecting mother takes into her body during the course of a typical day may affect her children and her grandchildren.

ScienceDaily (May 30, 2010) - A collaborative research team led by Queen's University biologists has found that potent metals like mercury and lead, ingested by Arctic seabirds feeding in the ocean, end up in the sediment of polar ponds.

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.

In May 2008, Josh Fox received a letter from a natural gas company offering to lease his family's land in Milanville, Pennsylvania for $100,000 to drill for gas.[1]Following the lease offer, he looked for information about natural gas drilling in the Marcellus Shale under large parts of Pennsylvania, New York, Ohio and West Virginia. He visited Dimock, Pennsylvania where natural gas drilling was already taking place. In Dimock, he met families able to light their tap water on fire as well as suffering from numerous health issues and fearing their well water had been contaminated.Fox then set out to see how communities are being affected in the west where a natural gas drilling boom has been underway for the last decade. He spent time with citizens in their homes and on their land as they relayed their stories of natural gas drilling in Colorado, Wyoming, Utah and Texas, among others. He spoke with residents who have experienced a variety of chronic health problems as well as contamination of their air, water wells or surface water. In some instances, the residents are reporting that they obtained a court injunction or settlement monies from gas companies to replace the affected water supplies with potable water or water purification kits.[2]Throughout the documentary, Fox reached out to scientists, politicians and gas industry executives and ultimately found himself in the halls of Congress as a subcommittee was discussing the Fracturing Responsibility and Awareness of Chemicals Act, "a bill to amend the Safe Drinking Water Act to repeal a certain exemption for hydraulic fracturing."[3] Hydraulic fracturing was exempted from the Safe Drinking Water Act in the Energy Policy Act of 2005.[4]Making appearances in the film are Dr. Theo Colborn, founder of the Endocrine Disruption Exchange (TEDX); John Hanger, Secretary of the Pennsylvania Department of Environmental Protection (DEP); Dr. Al Armendariz, Environmental Protection Agency (EPA) Administrator for Region 6; W

"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")

"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. "

Greenhouse gas emissions increased by a record amount last year, to the highest carbon output in history, putting hopes of holding global warming to safe levels all but out of reach, according to unpublished estimates from the International Energy Agency.
