What is Global Warming?

We hear about global warming all the time - our planet is unique in the sense it could well be the only one with life, so we need to preserve it. But at the moment we're damaging it. This is partly the aim of the UN's Global Goals. This is to ensure that future generations get to enjoy our planet too. Global warming is caused by increasing carbon dioxide levels - this leads to an increase in average global temperature.

Human activity has caused global warming by enhancing what's called the Greenhouse Effect. This is because, greenhouse gases absorb outgoing energy so less is lost to space. To some degree, the greenhouse effect essential to keep planet warm but too much and planet warms up.

The two most common greenhouse gases, carbon dioxide and methane are to blame for this increase.

Burning fossil fuels, farming and deforestation all increases atmospheric concentrations of carbon dioxide. This  effects all organisms and we need to do something about it!
