The signs of disruption to our climate are all around us. California has seen longer, hotter dry seasons leading to severe wildfires. Rising sea levels are threatening infrastructure and property along the State's coast, and a declining snow pack is causing concern for hydropower, water supply and tourism. Nationally, extended droughts over recent years have affected agriculture and led to higher food prices, and questions have been asked as to whether hurricane Sandy was a warning of more extreme weather and extensive damage to come. Across the world, further signs of climate disruption have been observed. Perhaps the most striking are the changes in the Arctic - at the end of summer the area covered by sea ice has reduced over the past couple of decades by a size equivalent to the majority of the eastern half of the United States.
How can we make sense of these signs of climate disruption? How urgent is it for us to respond? This talk will explain the math and science underlying the observed changes to our weather and climate and will discuss the projections of future change to help inform behavior or policy decisions.
