                 [Place clip art on the continuum below]




  Climate Change

Climate Variability

  Global Warming
  What is your perception of how the climate
   has changed where you live over the past
   30 years?


A. Much Warmer
B. Warmer
C. No Change
D. Cooler
E. Much Cooler
Change variability and change

Climate Variability: Natural changes in
climate falling in the normal range of
extremes for a particular region. Drivers
of climate variability include the El Niño
Southern Oscillation and other
phenomena.
                                 Climate Change: A significant and
                                 persistent change in the mean state of
                                 the climate or its variability. Drivers
                                 include regular changes in Earth’s orbit
                                 about the sun, re-arrangement of
                                 continents through plate tectonic
                                 motions, or anthropogenic modification
                                 of the atmosphere.
Global warming

Global Warming: The
observed increase in
average temperature
near the Earth’s surface
and in the lowest layer
of the atmosphere.
Global warming is a
type of climate change;
it can also lead to other
changes in climate
conditions, such as
changes in precipitation
patterns.
The world is getting warmer…

                                      Sea ice
In the Eastern United States…

 NORTHEAST:
   Average annual temperature increase of 2oF since 1970
   Increase in warm days, longer growing season, downpours
   Decrease in precipitation falling as snow

 SOUTHEAST:
    Average annual temperature increase of 2oF since 1970
    Seasonal changes in precipitation (e.g., 30% increase in Fall,
    decrease in summer)
    Increase in heavy downpours and drought coverage
    Increase in power of Atlantic hurricanes since 1970

Let’s Pause Two Minutes
 for Questions from the
        Audience
What are the Impacts?



       PART TWO
In the Eastern United States…

 NORTHEAST:
 Increasing health risks from extreme heat and declining air quality
 Adverse impact on production of milk, fruits, and maple syrup
 More frequent flooding from sea-level rise, storm surge, and heavy
 downpours
 Adverse impact on winter recreation, and lobster
               and cod fisheries
Coastal inundation impact…New York
In the Eastern United States…
 SOUTHEAST:
 Increases in air/water temperatures stress people, plants/animals
 Decreased water availability is very likely to affect the economy
        and natural systems
 Sea-level rise and increases in hurricane intensity and storm surge
        cause serious impacts
 Ecosystem thresholds crossed, leading to natural disruptions
 Severe weather events and reduced availability of insurance
Coastal inundation impact…Louisiana
Infrastructure impact…Gulf Coast
                  Poll Question


How significant do you think climate change impacts will be
   on ecosystems in the Eastern U.S. over the next 50
   years?
A) Devastating
B) Significant
C) Noticeable
D) Minimal
What Can We Do About It?



      PART THREE
The Choice

    “We basically have three choices:
    mitigation, adaptation, and suffering.
    We’re going to do some of each. The
    question is what the mix is going to be.
    The more mitigation we do, the less
    adaptation will be required and the less
    suffering there will be.”
                  John Holdren
                  President of the American Association for the
                  Advancement of Science; Harvard University
Responding to Climate Change

Mitigation: Reducing the amount of climate
change, for example, by reducing heat-trapping
emissions or increasing their removal from the
atmosphere

Adaptation: Improving our ability to cope with or
avoid harmful impacts or taking advantage of newly
favorable conditions

               BOTH will be needed.
Adaption case 1
Adaption case 2
Choosing the path
Reality check: where are we now?

                   Above even the
                    highest future
                         scenario
Who is responsible?
The value of climate literacy

Climate change will continue to be a significant element of public
discourse. Understanding the essential principles of climate science
will enable all people to assess news stories and contribute to their
everyday conversations as informed citizens.

                                                         2070-2099
