Kevin Anderson: Delivering on 2 degrees #IPCC #Paris #COP21

As part of the ‘Delivering on 2 degrees’ talks and debate evening organised by the Carbon Neutral University Network, Kevin talks about the Paris Agreement within the background of Climate Science and what is needed to stop global warming at 2C or even 1.5C. Kevin Anderson says that we basically lost the chance to stay…

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…

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…

Scientists: IPCC Underestimating Sea Level Rise

The Vision Prize is an online survey of scientists about climate risk. It’s an impartial and independent research platform for incentivized polling of experts on important scientific issues that are relevant to policymakers. Some of theirprevious survey results have found that about 90 percent of participating scientists believe that humans are the primary cause of…
