Paper 1
Revise: EnvironmentGlobal warming is the long-term rise in Earth's average temperature. Greenhouse gases trap heat in the atmosphere; increases caused by human activity strengthen this warming effect. These gases include carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O).
A long-term rise in the Earth’s average temperature, increased by greenhouse gases such as carbon dioxide.
Distinguish local pollution, such as chemicals entering a river, from global warming caused by increased greenhouse gases.
Keep environmental effects distinct: carbon dioxide contributes to global warming; sulphur dioxide can cause acid rain.
