Climate change

Climate change is the planet-wide variation in the Earth's climate owing to natural and man-made causes. Human actions are the main contributors to climate change and include the burning of fossil fuels, deforestation, and industrial, agricultural and transport activities. One consequence of these actions is that the Sun's heat is trapped in the atmosphere, a process that we know as the "greenhouse effect". The gases responsible for this phenomenon include carbon dioxide, nitrous oxide and methane.
