Every delegate to the Copenhagen summit is being greeted by the sight of a vast fake planet dominating the city’s central square. This swirling globe is covered with corporate logos – the Coke brand is stamped over Africa, while Carlsberg appears to own Asia, and McDonald’s announces “I’m loving it!” in great red letters above. “Welcome to Hopenhagen!” it cries. It is kept in the sky by endless blasts of hot air.

This plastic planet is the perfect symbol for this summit. The world is being told that this is an emergency meeting to solve the climate crisis – but here inside the Bela Centre where our leaders are gathering, you can find only a corrupt shuffling of words, designed to allow countries to wriggle out of the bare minimum necessary to prevent the unraveling of the biosphere.

Staggering across the fringes of the summit are the people who will see their countries live or die on the basis of its deliberations. Leah Wickham, a young woman from Fiji, broke down as she told the conference she will see her homeland disappear beneath the waves if we do not act now. “All the hopes of my generation rest on Copenhagen,” she pleaded. Dazed Chinese and Indian NGOs explain how the Himalayan ice is rapidly vanishing and will be gone by 2035 – so the great rivers of Asia that are born there will shrivel and cease. They provide water for a quarter of humanity.
