Politicians and pressure groups always seem to talk in terms of targets. But what are the different targets and what do they mean. Here is an attempt to explain.

1 DEGREE C

This is where we are now. The world is already 1 degree C warmer than pre-industrial levels. Last year saw hurricanes, droughts, floods and fires. We are now heading towards 1.5 degree C.

HIGHWAYS: POTHOLES

Suffolk County Council has paid out thousands of pounds to people in Bury St Edmunds who have fallen over on badly maintained pavements. Local Lib Dem campaigner Ed Allen says "It's shocking that in four years only 10% of the claims for compensation have been successful.

"Even if any highways repairs are carried out, the slap-dash quality of them means that the repairs do not last very long."

We only have twelve years left to radically alter our impact on the planet and to limit the climate change dangers of extreme weather, drought, floods and poverty.

It is already ten years since parliament passed the Climate Change Act. It was a radical piece of legislation - made more radical by Lib Dem input.

Lib Dem MP and former Energy Secretary Ed Davey said: "For the first time, the Act set meaningful and achievable targets to help us decarbonise. It's a model that has been adopted all over the world. The biggest Lib Dem successes came on renewables and European co-operation "

Liberal Democrats are open and outward-looking. We passionately believe that Britain is better off in the EU.

We acknowledge the result of the 2016 referendum, but we believe the final decision should be made by the British people, not by politicians.

If you agree, please write to your MP and urge him or her to support a People's Vote.
