By recycling at home, the UK has saved carbon dioxide equivalent to taking 5 million cars off the road from entering the atmosphere. This shows that small changes really do make a big difference.
However, more is needed. The Intergovernmental Panel on Climate Change (IPCC) warns that, if countries fail to act, the world will face catastrophic change - sea levels will rise, ocean temperatures and acidity will increase and our ability to grow crops, such as rice, maize and wheat, would be in danger.
The 20 warmest years on record have all been in the last 22 years with the last four years making up the top four. If this trend continues this could lead to a rise in temperature of between 3-5C by 2100. A rise in temperature of over 1.5C could have catastrophic, irreversible consequences for our climate.
