Speaker: Professor Dan Schrag

Prof. Dan Schrag will lead the discussion on the Schneider, Kaul, and Pressel (2019) paper titled Possible climate transitions from breakup of stratocumulus decks under greenhouse warming

During the disucssion, Prof. Schrag will lead us through the following:

This recent paper by Tapio Schneider presents a new idea for a cloud feedback that may amplify warming at higher CO2 concentrations.  If correct, it may have relevance for future climates in the next few centuries, and may also help to explain the observations from warm climates in Earth history, such as the Eocene.  For context, if you are interested (i.e., these ones are optional), you can also read an old paper by Danny Kirk-Davidoff (and Jim Anderson and myself) on a different mechanism for a similar type of feedback, and another one by Dorian Abbot and Eli Tziperman on an additional hypothesis of this type. (paper 1, paper 2, paper 3).
