GSCE Style Question:

The global temperature increases over time (1), and so does the
amount of CO2 (1). For example, in about 1910, the global
temperature was roughly -0.8 degrees (1) compared to the year
2000 when it reached almost 1 degree above the average (1).
CO2 has increased from 300 parts per million in 1920 (1) to nearly
380 parts per million in 2000 (1). In this 20 year period it has
increased by 80 parts per million (1) which is almost a quarter of
what it was in 1980.(1) Both CO2 and temperature rise quickly at
the some time. (1)

What gases cause global warming?
• Carbon dioxide, methane and other air
pollutants (Nitrous oxide, Ozone, Halocarbons
etc.) are collecting in the atmosphere like a
thickening blanket, trapping the sun's heat
and causing the planet to warm up.
