2 degrees, global warming and a planet under pressure?

The Planet Under Pressure conference has been taking place in London this week (26-29 March 2012), a major international gathering of policymakers, business leaders and scientists focusing on the challenges of global sustainability. On Monday delegates listened to a series of presentations on climate science and uncertainty. Coincidentally on the same day one of CEH’s climate scientists, Dr Chris Huntingford, had a new paper published in the journal Environmental Research Letters entitled “The link between a global 2°C warming threshold and emissions in years 2020, 2050 and beyond”.

The paper gives details of a recent study that investigates the link between the chances of global warming remaining below two degrees through to year 2500, and what this implies for emissions in 2020 and 2050. 2020 and 2050 are two ‘target’ years of particular relevance to policymakers, including many of those attending the Rio summit later this year.

You can hear Chris talk more about his climate modelling work in a video on our YouTube channel:
