Global Warming refers to surface temperature increases.

Climate Change refers to global warming and everything else that increasing greenhouse gas amounts will affect.

The Earth's climate is driven by a continuous flow of energy from the sun. Heat energy from the sun passes through the Earth's atmosphere and warms the Earth's surface.

These gases, which are all naturally occurring, act as a blanket, trapping in the heat and preventing it from being reflected too far from the Earth. They keep the Earth's average temperature at about 15°C: warm enough to sustain life for humans, plants and animals. Without these gases, the average temperature would be about -18°C... too cold for most life forms. This natural warming effect is also sometimes called the greenhouse effect.

The cause of climate change is the unlimited burning of fossil fuels – coal, oil and natural gas to satisfy our hunger for energy.

Climate change affects people and nature in countless ways, the impacts are large and complex and it often increases existing threats that have already put pressure on the environment and change on different areas, species, and people around the world: Coral bleaching, Polar regions, Glaciers, Extreme weather (Heatwaves, Droughts, Floods, Tropical cyclones/Hurricanes), species threatened, people at risk...
