Piers Sellers developer of the Simple Biosphere model, shuttle astronaut(1996-2011; 3 missions, 6 space walks), and current deputy director in sciences and exploration directorate at NASA GISS.
Good Talk
Very good information. Sellers gives us an overview of what has been happening to the planet these past decades in a series of stunning satellite images; temperature increases, the loss of sea ice, population increase and glacier retreat.
As Sellers notes: Things are happening faster than the models. So yes, we need to improve our modeling abilities.
