4.14 understand how an increase in greenhouse gases results in an enhanced greenhouse effect and that this may lead to global warming and its consequences

Heat from the sun is naturally radiated off the earth and into space. Greenhouse gases naturally keep in some of the heat (otherwise we would all die of cold, basically). However, increasing the amount of greenhouse gases is blocking the heat from escaping (known as the greenhouse effect). effectively, this heats up Earth, which is global warming.

Consequences of global warming include climate change (e.g. change in rainfall pattern)
