Arent a Lead Author on IPCC Report on Climate Change Impacts, Adaptation, and Vulnerability

JISEA's Doug Arent at the 10th Session of IPCC Working Group II, held 25 – 29 March 2014 in Yokohama, Japan.

March 2014 — The Intergovernmental Panel on Climate Change (IPCC) issued a report today that says the effects of climate change are already occurring on all continents and across the oceans. The world, in many cases, is ill-prepared for risks from a changing climate. The report also concludes that there are opportunities to respond to such risks, though the risks will be difficult to manage with high levels of warming.


The report, Climate Change 2014: Impacts, Adaptation, and Vulnerability, from Working Group II of the IPCC, details the impacts of climate change to date, the future risks from a changing climate, and the opportunities for effective action to reduce risks.

JISEA's Doug Arent was coordinating lead author of chapter 10 of the report. A total of 309 coordinating lead authors, lead authors, and review editors, drawn from 70 countries, were selected to produce the report. The authors and editors were selected in 2010 from a pool of more than 1,200 nominations.

The report concludes that responding to climate change involves making choices about risks in a changing world. The nature of the risks of climate change is increasingly clear, though climate change will also continue to produce surprises. The report identifies vulnerable people, industries, and ecosystems around the world. It finds that risk from a changing climate comes from vulnerability (lack of preparedness) and exposure (people or assets in harm's way) overlapping with hazards (triggering climate events or trends). Each of these three components can be a target for smart actions to decrease risk.
