Scientists need to stay true to the science AND They have to respect the fact that people have different values and political ideologies

“As scientists, we’re the map makers. As policymakers, you’re the navigators…” -- marine science and chemistry professor David Hastings (Eckerd College in Florida)

“Climate change threats to our coasts” OR “Coastal hazards: erosion, storms, development and rising seas” How is your talk being promoted?

Sequencing – When to bring up climate? Climate change is a hazard on our coasts We’ve tracked 10 inches of sea-level rise historically We have a best estimate of 1.3 feet of sea- level rise by 2050 This is happening alongside coastal threats from erosion, development, storms

We’re already dealing with coastal threats from erosion, development, storms We’ve tracked 10 inches of sea-level rise historically We best estimate of 1.3 feet of sea-level rise by 2050 So climate change is an additional hazard on our coasts that we can prepare for Sequencing – When to bring up climate?

“The impacts of climate change may increase the frequency, scale, and complexity of future missions…” – Department of Defense Quadrennial Defense Review Military Voices “Climate change is a national security challenge…it will affect the type, scope, and location of future Navy missions.” – U.S. Navy Climate Change Roadmap

Businesses “There is growing recognition that addressing the risk of climate change will require significant efforts by both the developed and the developing world.” – Exxon-Mobil “We realize we need to prepare for a future when carbon dioxide emissions must be reduced.” – Duke Energy “Energy and climate represent two of the most important business challenges of this century….” – General Electric
