Outline• Some facts about climate change in general• Climate change impacts in the New England region• Brief overview of what we can expect today
Key questions: What might we expect in the future and how can we prepare for it?
Facts about climate change• Intergovernmental Panel on Climate Change (IPCC) 2014:
– “Warming of the climate system is unequivocal…”
Facts about climate change• IPCC 2014:
– The ocean has warmed…Cooler than
average temperatures
Warmer than average
temperatures

Facts about climate change• IPCC 2014:
– “the amounts of snow and ice have diminished”

– “…recent anthropogenic emissions of greenhouse gases are the highest in history”

Evidence for and Consequences of Climate Change in the Northeast
• Projected long-term trends in climate and sea level rise
• Increased risk to coastal communities• Potential impacts on marine and
coastal ecosystems
Projected increases in average summer
temperatures in the Northeast for three time periods - early, mid-,
and late century

Average summer temperatures could increase by as much as 13o under high emission scenario!
• Changes in average summer heat index—a measure of how hot it actually feels, given temperature and humidity
• Yellow arrows track what summers would feel like under a lower-emissions scenario
• Red arrows track what summers could feel like under the higher-emissions scenario

And sea level is rising at an accelerating rate

Our purpose:• Raise awareness of the impacts of climate
change and rising sea levels
• Understand and educate how climate change is influencing our coasts and coastal communities
• Put science into action to identify strategies for resiliency and sustainability of our marine ecosystems, resources, and our economy and way of life
Schedule:• Day 1: Multi‐region dialogue and
educational campaign about the impacts of climate change with a focus on coastal areas in our region
• Day 2: Establish cross‐regional collaborations to share best practices, data, and expertise related to resiliency policy and planning
Keynote Speaker: Anthony Janetos• Professor of Earth and Environment at Boston University and Director of
the Frederick S. Pardee Center for the Study of the Longer-Range Future
• Prior executive leadership positions at institutions including the Joint Global Change Research Institute at the University of Maryland, U.S. Environmental Protection Agency, NASA, World Resources Institute, and the Heinz Center for Science, Economics, and the Environment
• Co-chair of the U.S. National Assessment of the Potential Consequences of Climate Variability and Change
• Intergovernmental Panel on Climate Change Lead Author and Coordinating Lead Author
Keynote Speaker: Amy Schatz• Producer and Director of Saving My Tomorrow, a six-
part family series on climate change through the eyes of children, presented by HBO and The American Museum of Natural History
• Emmy Award winning producer and director, whose work includes: Goodnight Moon & Other SleepytimeTales (1999), A Child's Garden of Poetry (2011) and An Apology to Elephants (2013)
