This interesting article by the UK's Tom Burke and John Ashton appeared a few days ago on Open Democracy. Worth a read. You can also take part in an online debate about it.
Quote: "Preserving a stable climate is essential for personal, economic and national security in the 21st century. The maintenance of security in all three modes is the primary task of government. A stable climate, like secure borders, safe streets, a healthy and educated population or efficient transport infrastructure is a public good. It can no more be achieved without public investment than can any other public good. Today there is a climate clock ticking out the future for us all."
