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
GLOBAL WARMING
Is the increase in the average
temperature of Earth’s near-
surface, air and ocean

Natural Causes
• Continental Drift
• Volcanoes
• The Earth’s Tilt
• Ocean Currents
Continental Driftis the movement of Earth’s continents relative to
each other.

What causes climate change?
Human Cause
• Green House
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.
Caulk, weatherstrip, insulate, and replace old windows
Buy products with a U.S. EPA
