Over the past three decades annual climate talks under the United Nations banner have become part of the Zeitgeist of a large movement. They draw government officials, think tanks, civil society, journalists and the occasional hipsters into negotiations over which ride trillions of dollars and our future well-being on Earth.
Advantages of a global carbon cap and trade system include the great flexibility with which it allows countries to meet their cap. Global ratification will ensure there is no "leakage" of emissions to countries not party to the agreement. However, the scope of these regulatory instruments is still limited in practice.
With the polls tightening and the bookmakers shortening their odds, there is now a very real chance that Scottish people will vote for independence in two weeks time...

We don't. Controlling the inexorably rising utility bills that plague households requires a longer term, more sustainable approach. In short, it needs us to learn how to use less.
In September 2014, ten teams will face each other on the tarmac for the first ever racing series that will feature only electric cars - the FIA Formula E World Championship.

But he is ready to take them on.
