Meet an IPCC Expert

Valérie Masson-Delmotte, Senior Scientist at the Climate and Environmental Sciences Laboratory in Gif-sur-Yvette, France, was the coordinating lead author of a chapter in the Fifth Assessment Report (AR5) published by the Intergovernmental Panel on Climate Change (IPCC).

"The report is written for the decision-makers in the different countries' governments. It is also intended for industry — and for everyone else, anyone who is curious about the subject."

Comprised of more than 800 experts from around the world, the intergovernmental panel on climate change (ipcc)Body established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) in 1988... combs through thousands of scientific studies and publishes three-part reports that set out current knowledge (AR5 was published in 2013-2014 and the one before in 2007). The reports aim to provide relevant scientific data to help the world's decision-makers craft climate policies; they are not intended to "prescribe" policy. The IPCC constantly stresses this point: its reports are "policy-relevant, NOT policy-prescriptive."

IPCC's reports detail global warmingGlobal warming, also called planetary warming or climate change... scenarios. It is up to policy-makers to make decisions.

The most recent one lays out four scenarios addressing rises in average global temperature of between 0.3° C and 4.8° C for the period 2081-2100, using the 1986-2005 average as a baseline. World leaders at the Copenhagen Summit settled on 2° C as the maximum acceptable increase.
