The COP27 climate summit in Sharm el-Sheikh has been billed as a “watershed moment” for climate change.
What are some key things countries need to do to tackle the problem?
Burning fossil fuels such as oil, gas, and especially coal, releases carbon dioxide (CO2) into the atmosphere, trapping heat and raising global temperatures.
It’s an issue which has to be tackled at government level if temperature rises are to be limited to 1.5C – the level considered the gateway to dangerous climate change.
However, a recent UN report, has said the ongoing use of fossil fuels means remaining below this temperature rise is now unlikely.
