Dr Gavin Schmidt speaking at the Royal Society 23 Sept 2014

The talk was called "Atmospheric composition and radiative impacts of Arctic sea ice loss" and was a keynote talk in the Royal Society Discussion Meeting "Arctic sea ice reduction: the evidence, models, and global impacts", Held at the Royal Society on 22-23 September 2014.


  1. An audience made up of about 200 scientists, journalists and the general public were in the meeting. It was also tweeted under the hash tag #RSArctic14. In a short while the audio of the talk will go on the Royal Society WWW site, and the talk is to be published as a paper in the Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences.
  2. The last session of the second day of the meeting was on "The impacts of Arctic sea ice loss"
  3. Dr Gavin Schmidt is the director of the Goddard Institute of Space Studies (GISS), and Principal Investigator for the GISS ModelE Earth System Model.
  4. So onto the talk.
  5. An early slide set out the elements of climate sensitivity.
  6. And for this talk the important elements are...
  7. Schmidt was clear about why the talk covers important material.
  8. So where are we now?
  9. So the increased atmospheric CO2 has implications...
