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.

Gases

“Greenhouse effect” Increasing greenhouse gases trap more heat

Greenhouse gases

Nitrous oxide

Water

Carbon dioxide

Methane

Sulfur hexafluoride

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.
