DESCRIPTION:\n\n \n\n\nDr. Klaus Keller\,  Department of Geosciences\,\nPen
 nsylvania State University\nAbstract: Model simulations and the geological
 \nrecord suggest that the Earth System can change abruptly and with\nlittl
 e warning time in response to small and smooth forcing. \nThe potential co
 llapse of the North Atlantic meridional\noverturning circulation (MOC) due
  to anthropogenic\ngreenhouse gas emissions exemplifies such a climate thr
 eshold\nresponse.  Currently\, the MOC sensitivity to anthropogenic\nforci
 ng is deeply uncertain posing unique challenges to the design\nof climate 
 risk management strategies. Here we analyze three\nquestions. Would the cu
 rrently implemented MOC observation system\ndeliver an actionable early wa
 rning sign of MOC changes before the\nsystem has been committed to a thres
 hold response? How could the\nMOC observation system be improved to delive
 r earlier and more\nprecise warning signals? What are economically efficie
 nt\nrisk management strategies in the face of uncertainty and\nlearning ab
 out climate thresholds?\nAll welcome.\n
