Canada's Impact
100
Increase in the global average surface temperature resulting from enhancement of the greenhouse effect, primarily by air pollution.
What is Global Warming
100
Warming that results when the atmosphere traps heat radiating from earth toward space
What is the greenhouse gas effect
100
In the last century, sea level rose about this many centimetres
What is 17
100
The fastest growing source of greenhouse gas emissions in Canada
What are the Alberta Oil Sands
200
According to IPCC a 1.8 - 4.0 degrees Celsius increase is forecasted to be this
What is the forecasted average temperature by 2100
200
This gas is the main contributor to the increase of the greenhouse effect that is warming our planet
What is CO2
200
Name 4 of the 8 evidence factors for global warming
What are rising sea levels, global temperature rise, extreme weather events, warming oceans, shrinking ice sheets, glacial retreats, ocean acidification, declining arctic sea ice
200
From the oil sands, this has almost tripled in the past 2 decades
What are greenhouse gas emissions
300
The intensification in temperature increase near the poles is largely the result of this
What is the loss of ice and snow cover
300
The “build up” of extra carbon in the atmosphere comes from this human activity to create energy
What is the burning of fossil fuels, coal, natural gas and oil.
300
The northern arctic ice cap is losing this much mass per decade
What is 15-20%
300
In this year, Canada abandoned the Kyoto Protocol
What is 2011
400
Since 1900, the global average temperature has risen by this many degrees Celsius
What is 0.7 degrees Celsius
400
Atmospheric CO2 has never been above 300 parts per million in this many years
What is 650,000 years
400
Corral bleaching is due to this evidence of global warming
What are warming oceans
400
Canada ranks this number in terms of tackling greenhouse gas emissions
What is 55th out of 58
500
The 20th century's last two decades were the hottest in this many years, and possibly the warmest for several millennia
What is 400 years
500
This term for clear cutting trees is another contributor to the excess build up of CO2 in the atmosphere
What is deforestation
500
Name 2 evidence factors that have not been mentioned yet
What are rising sea levels, global temperature rise, extreme weather events, warming oceans, shrinking ice sheets, glacial retreats, ocean acidification, declining arctic sea ice
