The problem – rising carbon dioxide in the atmosphere
The level of CO2 has been rising since the industrial revolution and is now at its highest for about 4 million years. The rate of the rise is even more striking – the fastest for 66m years – with scientists saying we are in “uncharted territory”.
The causes – fossil fuel burning
Billions of tonnes of CO2 are sent into the atmosphere every year from coal, oil and gas burning. There is no sign of these emissions starting to fall rapidly, as is needed.
