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

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

Page 19: Lohrenz GAEA presentation 120315 final REVISED sel...Outline • Some facts about climate change in general • Climate change impacts in the New England region • Brief overview

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
