What is climate change?

What examples of human behaviour, linked to climate change, are depicted in this image?

However, the term “climate change” is now being used to refer to the current climate. This is because recent evidence shows that the global climate seems to be changing more rapidly than usual, as a result of human behaviour.

Climate change is a natural phenomenon and normally takes place over several centuries.

A carbon footprint measures the impact human activities have on the environment in terms of the amount of greenhouse gas produced.

Your impact on the climate

Having some greenhouse gases benefits the planet. But humans keep adding to the greenhouse gases.

The Earth is kept warm by the atmosphere, a blanket of gases that act like the glass of a greenhouse.

Carbon footprint calculators ask what you eat, how you travel and what your home is like to

estimate the amount of carbon dioxide you create.
