Causes of Climate Change10 pointsANSWER

Changes in the Sun’s energy output are too small to be the cause of recent warming on Earth

The composition of Earth’s atmosphere

http://www.epa.gov/climatechange/students/basics/today/greenhouse-effect.html


Oxygen

Yes; small increases in carbon dioxide concentration have a large effect on the climate

system

Deforestation and burning fossil fuels increase the abundance of carbon in the

atmosphere

http://climate.nasa.gov/causes/


Airborne particulates cause cooling by reflecting incoming sunlight, and also

cause warming by absorbing and releasing heat energy in the

atmospherehttp://epa.gov/climatechange/science/causes.html


Gradual changes in Earth’s rotation and orbit around the Sun

Effects of Climate Change10 pointsANSWER

• The organisms will adapt, migrate, or die

http://www.epa.gov/climatechange/students/impacts/effects/ecosystems.html


• Earth’s average temperature is warmer than it has been for at least the past 1,300 years

http://www.epa.gov/climatechange/students/impacts/signs/temperature.html


Increased dissolved carbon dioxide is causing the ocean to become more acidic.

http://www.epa.gov/climatechange/students/impacts/signs/acidity.html


• Human activities, primarily burning fossil fuels

http://www.epa.gov/climatechange/students/basics/index.html


• Greenhouse gases

http://www.epa.gov/climatechange/students/basics/today/index.html


Both positive and negative changes are predicted, but the consequences of

negative impacts are likely to be much greater than the consequences of

positive impacts.http://www.epa.gov/climatechange/students/impacts/effects/index.html


Changing precipitation patterns and temperatures will reduce reliable access to fresh

water for many people. Winter snowpack and mountain glaciers that provide water for human use are declining as a result of global warming.

http://www.epa.gov/climatechange/students/impacts/effects/water.html


Sea level will rise, and changing temperatures may affect large current systems in Earth’s ocean

http://www.epa.gov/climatechange/students/impacts/signs/glaciers.html


Strong storms, heat waves, and changes in precipitation patterns are predicted to increase in

many locations

Human communities may face increased risks from violent weather events, changes in food and water

supplies, and infectious diseases
