DESCRIPTION:[The speaker is a Leverhulme Visiting Professor in DAMTP for t
 he period March-August 2022. This seminar is one of two 'Leverhulme Lectur
 es' that he will give during his stay here.]\n\nThe dryness of terrestrial
  climate can be measured in terms of an\naridity index that is the ratio o
 f annual precipitation to potential\nevapotranspiration. The United Nation
 s Environment Programme defines\ndrylands as the terrestrial areas with an
  aridity index of less than\n0.65\, which are further classified into hype
 r-arid\, arid\, semiarid\, and\ndry sub-humid lands.  In this talk I will 
 present the response of\nterrestrial aridity and dryland areas to global w
 arming in the framework\nof the UNEP aridity index.  A mechanism that “w
 armer is more arid” will\nbe discussed.  The implications to geoengineer
 ing and droughts will also\nbe discussed.
