Former chair says IPCC must acknowledge mistakes and “consider shorter reports focused on the key issues,” but “In many cases, the IPCC is very conservative in its statements, e.g., the projections of sea level rise.”
All major emitters of carbon dioxide and other greenhouse gases need to rapidly and cost-effectively transition to a low-carbon economy, in both the production and use of energy and the management of forests and agricultural lands. In order to ensure food, water, and human security, and to protect the world’s biodiversity, the goal should be to limit the global average temperature rise to 2 degrees C (3.6 degrees F) above pre-industrial levels…. Without concerted action now, the world will be faced with temperature increases far in excess of 2 degrees C, with unthinkable impacts.
Dr. Robert Watson was chair of the Intergovernmental Panel on Climate Change from 1997 to 2002. He was opposed by fossil fuel companies like ExxonMobil and the Bush administration waged a successful campaign to have him replaced with Rajendra Pachauri. Now Watson is Strategic Director for the Tyndall Center at the University of East Anglia and Chief Scientific Advisor for the UK Department for Environment, Food and Rural Affairs. Yale’s Environment 360 online magazine has a piece by him they have given me permission to repost.
