CounterPunch: The U.S. Department of Defense released the 2014 version of its Quadrennial Defense Review (QDR) yesterday, declaring the threat of climate change impacts a very serious national security vulnerability that, among other things, could enable further terrorist activity. Released every four years, the QDR is a broad outline of U.S. military strategy discussing how to maintain global U.S. military hegemony. Like the 2010 document, the 64-page 2014 QDR again highlights the threats posed to national...

Examiner: The effects of climate change are "threat multipliers" that will force the Pentagon to rethink how it engages in training, missions and humanitarian aid around the world, the Defense Department said Tuesday in its Quadrennial Defense Review. The review, released every four years, steps up calls made to address climate change in the last version. It noted climate change would "aggravate stressors" such as "poverty, environmental degradation, political instability and social tensions -- conditions...

Blue and Green: The impacts of climate change are being felt at even the deepest depths of the Antarctic ocean, a new study has found, in a discovery that may explain a 40 year old mystery. In the mid-1970s, the first satellite images to be studied of Antarctica during the polar winter discovered a strange phenomenon. In the Weddell Sea, researchers noticed a huge ice-free region known as a polynia that remained open for three winters. Scientists found that the polynia was kept open by warm waters that...

RedOrbit: By studying thousands of canopy tree species in the western Amazon, researchers from the Carnegie Institution for Sciences Department of Global Ecology have uncovered geographically nested patterns of chemical traits they say will help determine how the ecosystem will respond to changes in land use and climate. Writing in the March 3 edition of the Proceedings of the National Academy of Sciences (PNAS), the study authors set out to determine how much variation there is in the chemicals generated...

Reliance on fewer crops increase climate change food security threat

Blue and Green: As people from all corners of the world are living off an increasingly similar diet, decreasing crop diversity is making the global food system more vulnerable to the impacts of climate change, a new study has warned. The study, which is published in the journal Proceedings of the National Academy of Sciences of the United States of America, claims to be the first to quantify the effects of a trend towards a unified international diet over the last 50 years. "Over the past 50 years, we are...
