Impacts of Climate Change Climate change is apparent now across our nation. Trends observed in recent decades include rising temperatures, increasing heavy downpours, rising sea level, longer growing seasons, reductions in snow and ice, and changes in the amounts and timing of river flows. These trends are projected to continue, though larger increases would result from higher levels of heat-trapping gas emissions, and smaller increases from lower levels of these emissions. The observed changes in climate are already causing a wide range of impacts, and these impacts are expected to grow. Sea Ice and Permafrost Sea Ice and Permafrost Forests Risks and costs in Alaska increase as thawing of permafrost damages Forest growth is generally projected to increase roads, buildings, and forests, and in much of the East, but decrease in much of the declining sea ice increases coastal West as water becomes even scarcer. Major erosion and threatens the existence of shifts in species are expected, such as maple- so some communities. e co u t es beech-birch forests being replaced by oak-hickory beech birch forests being replaced by oak hickory in the Northeast. Insect infestations and wildfires are projected to increase as warming progresses.

Coral Reefs Rising water temperatures and ocean acidification threaten coral reefs and the rich ecosystems they support These and other ecosystems they support. These and other climate-related impacts on coastal and marine ecosystems will have major implications for tourism and fisheries. 2 2 Global Climate Change Impacts in the United States
Responding to Climate Change Responses to climate change fall into two major categories. “Mitigation” focuses on reducing emissions of heat-trapping gases and particles to reduce the amount and speed of climate change. “Adaptation” refers to changes made to better respond to present or future climate conditions in order to reduce harm or take advantage of opportunities. Both are necessary elements of a comprehensive response strategy.

Two Complementary Responses to a Changing Climate Miti Mitigation : reduce emissions; energy ti d i i efficiency; alternative energies, etc. Implementation: NOW and save money p y Impacts on climate change: 50-100 yrs. Adaptation : planning ahead; incorporating Adaptation : planning ahead; incorporating likely future climate states into regular planning; taking action Implementation: NOW and in future Impacts on community: Now and Future.

Adaptation • No “top 10” Adaptation Actions • Adaptations are location and issue specific Adaptations are location and issue specific • Adaptive capacity is uneven w/in & across society: resources ($, info., expertise); political will; stringent policies and regulations; cultural acceptability; not automatically translate into reduced vulnerability • Scale of info must match scale of issue • Rarely only because of climate change: multiple stressors R l l b f li h ( e.g. growing populations in harms’ way ); hazard management • Climate change a moving target: • Climate change - a moving target: requires i continuous reassessment

Communities Have: • A lot to lose from climate impacts: slr, storms, water issues, health impacts, forest , , , p , fires, etc. • Limited resources and tight budgets: competition – g g p elderly, economy, energy, environment • Much to gain from opportunities: economic Much to gain from opportunities: economic dev., energy savings, avoided costs • Relevant authorities: blgd and dev permits Relevant authorities: blgd and dev permits (influence land use), building codes, public transit • Opportunity to learn from and work with other Opportunity to learn from and work with other communities
