The Earth's climate has changed many times during the planet's history, with events ranging from ice ages to long periods of warmth. Historically, natural factors such as volcanic eruptions, changes in the Earth's orbit, and the amount of energy released from the Sun have affected the Earth's climate. Beginning late in the 18th century, human activities associated with the Industrial Revolution have also changed the composition of the atmosphere and therefore likely are influencing the Earth's climate.

Is the climate change really happening? Is it being caused by people? These important questions often come up when we take a closer look at the subject of the climate. These are the Intergovernmental Panel on Climate Change (IPCC)'s answers to those two questions:
- "A growing number of observations provide a collective picture of an Earth that is warming up, together with other changes in the climate system."
- "There is new and clearer evidence that the majority of the warming that has taken place in the last 50 years is due to human activity."
This means that actions have to be taken to protect the climate, even if we cannot prove with absolute certainty that certain climate change phenomena are the consequences of human activity.

As a result of this, we can never be absolutely 100 per cent certain as to why the climate is changing, or how it is going to change in the future. However, most scientists and politicians no longer dispute the fact that the earth has warmed up substantially due to the increased ”man-made" emission of greenhouse gases.

The world’s leading science journals report that glaciers are melting ten times faster than previously thought, that atmospheric greenhouse gases have reached levels not seen for millions of years, and that species are vanishing as a result of climate change. They also report of extreme weather events, long-term droughts, and rising sea levels.
Fortunately, the science also tells us how we can begin to make significant repairs to try and reverse those impacts, but only through immediate action.
