The musicians have made the plea to leading politicians ahead of COP21, a United Nations conference on climate change which begins in Paris, France on Monday (30Nov15).

An extract from the letter, which has been published online, reads, "We are deeply concerned that our global economic and industrial systems are accelerating rates of extinction, desertification and soil depletion, degrading ecosystems, acidifying and littering our rivers and oceans, and resulting in a relentless rise in greenhouse gas emissions driving irreversible climate change.

"In short, we are overwhelming the planet's life support systems. The outcomes of COP21 and the political decisions taken over the next months will determine many of the long-term conditions that will affect us today and for many generations to come."

The stars have pledged to make their own businesses more sustainable and to use their fame to raise awareness, and in exchange, they are asking for leaders to make "an ambitious commitment to climate action, starting now, that will limit future global warming."

The letter concludes, "We understand the gravity of climate change and the historic opportunity represented by COP21. We will come together and intensify our efforts, but we need you to give us confidence in a sustainable future, to share our ambition... We Must, We Can, and together We Will act on climate change."

Other signatories include Coldplay, Yoko Ono, Iggy Pop, Colin Firth, Steve Coogan and Emma Thompson.
