4.4.3 The impact of a gas Outline the two factors that determine the impact of a greenhouse gas: depends on its ability to absorb long-wave radiation as well as on its concentration in the atmosphere. 4.4.4 The warmed Earth Describe how the surface absorbs and emits solar radiation: Earth’s emits longer-wave radiation (heat). 4.4.5 Longer-wave Describe the greenhouse effect: radiation is reabsorbed by greenhouse gases which retains the heat in the atmosphere. 4.4.9 Correlations between global temperatures and carbon dioxide concentrations on Earth. 4.4.6 Global temperatures Outline the climate effects of higher greenhouse gas concentrations and global temperatures: and climate patterns are influenced by concentrations of greenhouse gases. 4.4.7 There is a correlation Describe the correlation between atmospheric carbon dioxide and temperature: between rising atmospheric concentrations of carbon dioxide since the start of the industrial revolution How is this related to the start of the industrial revolution? two hundred years ago and average global temperatures. 4.4.8 Recent increases in atmospheric carbon dioxide are largely due to increases in the combustion of fossilized organic matter. 4.4.10 Evaluate claims that Discuss claims that human activities are not related to climate change: human activities are not causing climate change. 4.4.11 Threats to coral reefs How does increasing carbon dioxide threaten coral reefs? from increasing concentrations of dissolved carbon dioxide.
