Sea Level Rise Projections until 2100, a nonlinear response?

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…

Climate Change with George Monbiot and George Marshall | Guardian Live

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…

A journey from 5°C to 2°C – Glen Peters, CICERO

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…

A world with this much CO²: lessons from 4 million years ago

With Dr Chris Brierley, UCL Geography In Spring last year, carbon dioxide concentrations passed 400 parts per million in the atmosphere — a level not seen since the Pliocene era (3-5 million years ago), and perhaps not even then. We know that the Pliocene was a warm world without glacial cycles, and that the climate…

Once you have a release of fracking fluid into the environment, you end up with a radioactive legacy

Recent studies link radioactive compounds to fracking. This was first made public back in 2010, with the conclusion ‘Fracking’ Mobilizes Uranium in Marcellus Shale. Now a new study aimed to better understand cumulative effects of natural occurrences and new anthropogenic pathways, through fracking-drilling. Indoor radon levels in Pennsylvania have been slowly rising since 2004, around the…

Colbert Sums Up GOP on Climate Change: ‘We Don’t Know What the F*ck We’re Talking About’

November 2014: With the Republican Senate victory Tuesday came the slow realization that Sen. James Inhofe (R-OK), a man who literally wrote the book on climate change denial, was poised to takeover the Environment and Public Works Committee. On Thursday night, Stephen Colbert used Inhofe’s views as a jumping off point to examine the GOP’s…

Calls for Harvard University to Divest Fast from Fossil Fuels #TippingPoint

CNN: Stanford University has already decided it will no longer directly invest in coal mining companies because it has a responsibility to consider “corporate policies or practices (that) create substantial social injury.” Harvard is fighting climate change, too. The university has an enviably small carbon footprint and its scientists are among the most respected for…
