The Earth's climate has changed many times over the course of its history. We've had ice ages and warm periods in the past, but this time it's different. The current rate of global warming is unprecedented - and it's caused by us humans.
It's all down to the greenhouse effect. When we burn fossil fuels they emit carbon dioxide which becomes part of our atmosphere. This traps heat like a blanket, warming the planet. The heat causes more water vapour to enter the air, another greenhouse gas, and the effect escalates.
Usually, nature's carbon cycle would remove the extra carbon dioxide. But we've added so much of the gas to the air that nature can't keep up. However, there are ways we can fight global warming. Have a go at this quiz and see if you know the causes of climate change and the ways we can tackle it.

That doesn’t sound like much but if temperatures continue to rise the effects will be disastrous
|
And that’s not all - we also expect to see more droughts, famines, and mass movement of people. There might even be wars fought over increasingly scant resources

Carbon dioxide in the atmosphere has increased by almost 50% since the Industrial Revolution - coincidence? I don't think so!
|
They are right to say that Earth’s climate has changed before due to greenhouse gasses, usually emitted by volcanoes. The difference this time is the sheer amount of pollutants and the fact that it’s us humans who are producing them

In 2017, then US President Donald Trump announced that the United States would withdraw from the agreement. He is on record for saying that climate change is a "hoax”
|
We are by no means the worst offenders - Qatar produces six times as much per person. But before we congratulate ourselves, let's remember that we need to cut all carbon emissions by at least 50% to stop global warming

Most greenhouse gas emissions come from electricity and heat generation. Transport is the second worst offender and with manufacturing and farming sharing third spot.
The answer is not to stop industry - rather, we must find greener ways to warm, feed and transport ourselves |
Unless things change soon, the sea will have risen by over a metre by the year 2100. That's enough to drown some low-level islands and to alter some coastlines

Before the Industrial Revolution, there were approximately 278 ppm of carbon dioxide. The burning of fossil fuels is the obvious connection

World governments can make the biggest difference, but we can all do our bit to help save the planet
