Do you remember ONDOY?

Are you one of them?

Are you ready for this?

What have we done?

WE ARE ALL VICTIM

CLIMATE CHANGE• Is a change in the statistical

distribution of weather over periodic of time that range from decades to millions of years.

• Climate change may be limited to a specific region or may occur across the whole earth or planet

Could the warming be natural?

Is it real?

Effects: Snow and ice

Grinnell Glacier, Glacier National Park1900 and 2008

Aspen, CO Forecast:

Partly cloudy todayHigh : 28°FLow: 13°F

Increasing clouds over night. Colder tomorrow.

Effects on ecosystems

2003 European Heat Wave

Germany: Lowest river levels this century

Switzerland: Melting glaciers, avalanches

France: >14,000 deaths

Portugal: Forest fires

U.K.: Train rails buckle

Sea-level rise projections : a few inches to a few feet

•2 ft: U.S. would lose 10,000 square miles•3 ft: Would submerge Miami

Produce more fuel-efficient vehicles

Reduce vehicle use

Improve energy-efficiency in buildings

Develop carbon capture and storage processes

Triple nuclear power

Increase solar power

Decrease deforestation/plant forests

Improve soil carbon management strategies

Individual actions

Use mass transit, bike, walk, roller

skate

Tune up your

furnace

Unplug appliances or

plug into a power strip and

switch it off

Buy water-saving appliances and

toilets; installing low-flow shower

heads.

Caulk, weatherstrip, insulate, and replace old windows
