By Daniel L. Kuester, U.S. Naval War College Public Affairs Feb. 4, 2015 NEWPORT, R.I. – Author, researcher and marine biologist Jeremy Jackson gave a presentation titled “Sea Level Rise is Dangerous” at U.S. Naval War College (NWC), Feb. 3, addressing environmental changes and the implications of those events on people. “The threats to the…

If you thought oil companies might start to transition to a world without carbon, invest into renewable energies to get ahold of it. Then the message is often pretty clear, they do exactly the opposite, and do not care. Earthquake research For instance oil billionaire Harold Hamm was bold and demanded from the University of…

Developing crude oil is extremely hazardous in the Arctic, because of strong ocean currents, severe storms and floating ice. (2014 report) http://www.climatecentral.org/news/melting-sea-ice-makes-arctic-drilling-a-risky-business-17018 Offshore drilling https://en.wikipedia.org/wiki/Offshore_drilling Seabed gouging by ice, Oil and gas developments in Arctic waters must address environmental concerns through proper contingency plans. Large parts of the Arctic are covered with ice. During the…

Past sea level rise is not captured by models yet, in particular the response from ice sheets in Antarctica due to global warming. Projections therefore can often be regarded to potentially underestimate future sea level rise. For example, Overpeck et al. (2006), and Hansen (2007) suggest possibilities which could eventually lead to a nonlinear response…

ClimateProgress What’s the best way to show a climate change denier the error of their ways? A new online course answers this question for the masses. Hint: it’s not lobbing an endless stream of scientific evidence that proves human-driven climate change. While this approach may be cathartic, telling those who refuse to accept climate science…

Despite the overwhelming evidence, the majority of us have become increasingly adept at ignoring or side-lining climate change. Most of us recognise the danger is real and yet we do nothing to stop it. As the Guardian sets out on its own climate change journey, George Marshall, one of the most eminent thinkers in the…

The Antarctic ice sheet is one of the two polar ice caps of the Earth. It covers about 98% of the Antarctic continent and is the largest single mass of ice on Earth. It covers an area of almost 14 million square km and contains 26.5 million cubic km of ice. That is, approximately 61…

5C is the temperature increase above pre-industrial levels we are heading for if we follow our path of limited or no climate policy. 2C is the temperature increase above pre-industrial levels that most countries around the world have agreed would prevent dangerous climate change. This journey will describe how the energy system must change if…

Sea ice melt season 2015 Last year a study reported that the Arctic sea ice melt season is getting longer. The situation for the state of the Arctic sea ice this year is already critical, since April 2015 set the 2nd lowest sea ice extent record (NSIDC). A decline of 2.4% per decade relative to…

NASA has found that the last section of Antarctica’s Larsen B Ice Shelf is likely to disintegrate before the end of the decade. Transcript: We know that this ice shelf existed for at least 11 to 12 thousand years. In 2002, two-thirds of it collapsed in less than six weeks. In the intervening period between…

Ocean access to a cavity beneath Totten Glacier in East Antarctica http://www.nature.com/ngeo/journal/v8/n4/full/ngeo2388.html Totten Glacier, the primary outlet of the Aurora Subglacial Basin, has the largest thinning rate in East Antarctica1, 2. Thinning may be driven by enhanced basal melting due to ocean processes3, modulated by polynya activity4, 5. Warm modified Circumpolar Deep Water, which has…
