Arctic Atmospheric Circulation, Freshwater and Sea Surface Height

NASA 2012: The transpolar drift (purple arrows) is a dominant circulation feature in the Arctic Ocean that carries freshwater runoff (red arrows) from rivers in Russia across the North Pole and south towards Greenland. Under changing atmospheric conditions, emergent circulation patterns (blue arrows) drive freshwater runoff east towards Canada, resulting in freshening of Arctic water…

Vanishing Arctic Ice and Amplification

While heat waves and more intense storms have been directly linked to a warming Earth, new research is exploring possible impacts of an Arctic that is warming at twice the pace of the rise in global temperatures. Jennifer Francis, Rutgers University, discusses new research and efforts to understand this controversial aspect of climate change in…

Warlike Climate Mobilization

The Climate Mobilization Victory Plan, written by Ezra Silk, is a policy document that tangibly demonstrates how the U.S. could eliminate net greenhouse gas emissions by 2025, contribute to a global effort to restore a safe climate, and reverse ecological overshoot through a massive WWII-scale mobilization. http://www.postcarbon.org/the-climate-mobilization-victory-plan-foreword The Victory Plan (PDF) https://drive.google.com/file/d/0ByftlCTrJRYVejBuYUZkM1dKcms/view The Climate Mobilization…

Atmospheric Oxygen Decline threatens Humanity’s Existence

Study: There has been a clear decline in the volume of oxygen in Earth’s atmosphere over the past 20 years. A recently proposed model predicts a non-linear decay, which would result in an increasingly rapid fall-off in atmospheric oxygen concentration, with potentially devastating consequences for human health. We predict that humans may continue to survive…

Drew Shindell: Climate Policy to Avoid Tipping Points

Head of the SAP, Drew Shindell, talks about why a near-term climate goal is important, the main message the article aims to convey, why governments should adopt a near-term goal, and whether reducing near-term warming can prevent climate tipping points. The Climate and Clean Air Coalition’s Scientific Advisory Panel (SAP) published an article in Science…

The National Security Implications of Climate Change (June 2017)

On June 5, The Center for Climate and Security (CCS) and the Environmental and Energy Study Institute (EESI) hosted a briefing on Capitol Hill exploring climate change risks to U.S. national security – particularly, the effect on Department of Defense (DoD) force readiness, missions and infrastructure. The discussion ranged from prospective impacts on overseas missions,…
