Turning the Climate Tide by 2020

The world needs high-speed climate action for an immediate bending-down of the global greenhouse-gas emissions curve, leading experts caution. Aggressive reduction of fossil-fuel usage is the key to averting devastating heat extremes and unmanageable sea level rise, the authors argue in a comment published in the renowned scientific journal Nature this week. In the run-up to the G20 summit of the planet’s leading economies, the article sets six milestones for a clean industrial revolution. This call for strong short-term measures complements the longer-term 'carbon law' approach introduced earlier this year by some of the current co-authors, including the Potsdam Institute’s Director Hans Joachim Schellnhuber, in the equally eminent journal Science. Thus a full narrative of deep decarbonization emerges.

“We stand at the doorway of being able to bend the GHG emissions curve downwards by 2020, as science demands, in protection of the UN Sustainable Development Goals, and in particular the eradication of extreme poverty," Christiana Figueres says, lead-author of the Nature comment and former head of the United Nations Framework Convention on Climate Change (UNFCCC). "This monumental challenge coincides with an unprecedented openness to self-challenge on the part of sub-national governments inside the US, governments at all levels outside the US, and of the private sector in general. The opportunity given to us over the next three years is unique in history.” Figueres is the convener of Mission 2020, a broad-based campaign calling for urgent action now to make sure that carbon emissions begin an inexorable fall by 2020.

The authors and co-signatories to the Nature article comprise over 60 scientists, business and policy leaders, economists, analysts and influencers, including Gail Whiteman from Lancaster University; Sharan Burrow, General Secretary of the International Trade Union Confederation; Paul Polman, Chief Executive Officer of Unilever plc; Anthony Hobley, Chief Executive of Carbon Tracker; Christian Rynning-Tønnesen, CEO of Statkraft; and Jonathan Bamber, President of the European Geosciences Union.
