BX2184 W2 Global Challenges

Carbon dioxide released by burning fossil fuels and agricultural and industrial activity has raised the concentration of carbon dioxide in the atmosphere leading to climate change.

• True

• False

Four indicators of climate change are:

• CO2 concentration, ocean acidification, global mean surface temperature, sea level rise.

• Increasing artic sea ice, ocean acidification, global mean surface temperature, sea level rise.

• CO2 concentration, decrease in acidity of oceans, global mean surface temperature, sea level rise.

• greenhouse gas emissions, ocean acidification, global mean surface temperature, sea level decrease.

The word "mitigation" in relation to climate change, involves:

• Living with climate change and coping with its harmful effects

• Making the most of any potential beneficial opportunities associated with climate change (for example, longer growing seasons or increased yields in some regions)

• Reducing the flow of heat-trapping greenhouse gases into the atmosphere, either by reducing sources of these gases (for example, the burning of fossil fuels for electricity, heat or transport) or enhancing the “sinks” that accumulate and store these gases (i.e. the forests)

• None of the above

The term 'biosphere' refers to:

• the life-supporting surface of the Earth, including oceans, soil and atmosphere.

• the life-supporting surface of Mars, including oceans, soil and atmosphere.

• a specific climate zone and the plants and animals it supports.
