Introduction, Goals of the Workshop

 Columbia Ini-a-ve on Extreme Weather and Climate •  How can we quantify and respond to the risk of
extreme events in our present and future climate?
2 “Extreme weather and climate” means: 1. Extreme weather events and their rela-on to climate. Allen et al. (2015), Nature Geoscience “Extreme weather and climate” means: 2. Extreme climate events (also related to s-ll longer-­‐term climate) Lake Mead (credit: USGS) For some purposes (esp. shorter term), climate change isn’t necessarily the main issue. hQp://sedac.ciesin.columbia.edu/data/collec-on/ndh/maps/gallery/search For some purposes (esp. shorter term), climate change isn’t necessarily the main issue. But from the broadest perspec-ve, it is. IPCC AR5 (2013) Was extreme weather event X related to climate change?

Na-onal Geographic, Jan. 26, 2015 Reuters, Jan. 29, 2015 Climate Progress, Jan. 26, 2015 It’s our job as scien-sts to try to answer this… but it’s not the most fundamental ques-on.
