Describes the earth's average surface temperature for the past 900,000 year

Prolonged periods of cooling and warming

The most abundant greenhouse gas in the atmosphere

Water vapor

The gas that has shown the greatest increase since the industrial revolution

Carbon dioxide

The average rise in global temperature in the last 100 years

1 degree F

The increase in carbon dioxide, in ppm, the last 200 years.

100 ppm

Methods of deriving past climate history

Tree ring data, ice core bubbles, pollen and plankton artifacts, and radioisotopes of rocks and fossils

The heat-waste problem can only be solved by

Increasing the energy efficiency

Problems associated with ocean surface acidity

Disruption of food webs, reducing iron levels need for photosynthesis, decreasing phytoplankton populations, and dissolving calcium carbonate shells of marine animals

Possible disastrous effects of a warmer atmosphere

Sea level rise, Health problems, ice and snow melting, and flooding or drought

Climate models predict that global warming will be most severe in

Polar regions

Adverse effects of rising sea levels

Contaminate coastal aquifers, disrupt coastal fisheries, accelerate coastal erosion, and flood areas where one-third of the world's human population lives

Reasons why addressing global climate change is difficult

The problem is global, not regional, the problem is global, not regional, problems will be solved by long-term political solutions, and many of the problems and solutions are controversial

Strategies to reduce climate change

Improve energy efficiency, stop cutting down tropical forests, carbon capture, and shift from fossil fuels to a mix of carbon-free energy resources

Examples of carbon capture and storage

Massive planting of trees, the use of biochar for fertilizer, growing more switchgrass, and pumping it deep underground

Strategies to prevent climate change

Reduce deforestation, slow population growth, improve energy efficiency, and shift from coal to natural gas

The Kyoto Protocol

The mission of the treaty was to slow global warming and climate disruption

The country who's goal is to reduce carbon emissions to zero by 2030

Costa Rica

Efforts made to reduce CFC and HFC emissions

Copenhagen Protocol, Montreal Protocol, US asked UN to enact mandatory reductions, and DuPont replaced CFC with higher priced alternatives

Effects of ozone depletion on humans

Suppression of immune system, more cataracts, worse sunburn, and more skin cancers

Products containing CFCs

Cleaners for electronic equipment, gases for insulation and packaging, propellants in aerosol spray cans, and coolants in air conditioners and refrigerators

Chemicals capable of destroying ozone (other than CFCs)

Halons in fire extinguishers and crop fumigants, carbon tetrachloride used as a solvent, and methyl bromide used as a fumigant

Expected results of phasing out ozone depleting chemicals

Improved health benefits, increase in phytoplankton productivity, and reduced risk from sunburn and UV exposure

Location of the ozone hole

Antarctica

Where ozone depletion is occurring in the atmosphere

Stratosphere

Where global warming is occurring in the atmosphere

Troposphere
