Agenda

NESSC symposium on Climate Sensitivity

We are pleased to invite you to the upcoming NESSC symposium: “Equilibrium Climate Sensitivity: Past, Present and Future – Knowledge gaps in IPCC” organized in Utrecht on Monday the 9th of July 2018.

About the symposium
The day will start with registration and coffee & tea between 10.00h and 10.30h. At the end of the day there will be an open discussion to discuss knowledge gaps in the IPCC reports, followed by social drinks (17.00h).

Preliminary list of speakers: Heather Stoll, Clara Bolton, Stefano Bernasconi, Alan Haywood, Dan Lunt, Yannick Donnadieu and Qiong Zhang.

The symposium is part of a meeting of international experts on climate sensitivity, who are preparing a EU proposal on this topic. The symposium is funded through the NESSC workshop program and is therefore free of charge, including lunch and drinks.

Registration
Please register per e-mail (before July 2) to t.vos@uu.nl. If you are registering any colleagues please include their names and email too. Let us know if you have any dietary requirements.
