Global Warming & Climate Change

The planetary albedo refers to...

• the ability of the planet to reflect solar radiation back into space.

• the ability of the planet to absorb solar radiation in the surface.

• the ability of the planet to deflect the solar radiation before it reaches the surface.

• the ability to trap the energy of solar radiation within our atmosphere.

Which gas is not a GHG?

• Water vapour

• Carbon dioxide

• Methane

• CFCs

• Nitrogen

Which two opetion are examples are positive feedback loops.

• increased carbon dioxide released from increased biomass

  decomposition are added to the atmosphere

• increased forest cover in high latitudes, decreasing albedo and

  increasing warming.

• burning, leading to more aerosols and thus reduced solar radiation at the surface, thereby causing cooling

• increased evaporation, increasing cooling.

The enhanced greenhouse effect is linked to

• industrialization

• trade

• globalization.

• the destruction of the Ozone Layer

Which answer is incorrect: Global warming is predicted to have various far-reaching effects on the natural, social and economic environment:

• Sea levels will rise

• Storm activity will increase

• Agricultural patterns will change

• Unemployment will increase

The term " hydrosphere " refers to...

• freshwater, seawater and ice/glaciers

• all the water in our atmosphere

• all the oceans

• rivers, lakes, and dams

The impact of global warming on the hydrosphere will include:

• a rise in sea levels

• floods from melting glaciers

• droughts and famine

• wild fires

The impact of global warming on sea ice include...

• the arctic ice will decline

• positive feedback loop of disappearing sea ice

• the extiction of wild life and fish species

• the loss of land for people who live in the arctic regions.

How have we changed the amount of carbon that is stored in ice, oceans and the biosphere?

• We have added carbon bacause of industrilization, travel, and trade.

• We have removed more forms of clean energy due to the fact that it is expensive.

• We have removed more trees from the Amazon, Central Africa, and South East Asian rainforests.

• We are still using fossil fuels like oil, natural gas, and coal.

Agriculture has had a variable impact on the Earth’s carbon cycle because...

• forests are turned into farmland.

• the burning of wild fires add CO2 to the atmosphere.

• farm animals have a very high carbon footprint.

• forest are being removed because people need lumber and wood for contruction purposes.
