Get this - last weekend over 700 shameless French men and women stripped down to pose nude in Burgundy vineyards to warn the world about the impact of global warming on the French wine industry. It’s all part of the campaign to urge political leaders to take action in the lead up to the U.N.’s Climate Change Conference in Copenhagen in December.

So how, you may ask, is climate change affecting the French wine industry? According to a recent Greenpeace report, who helped organise the naked get-together, warmer temperatures mean that the harvest is taking place earlier.

“Wines end up having higher sugar levels and alcohol content while retaining less acids - which means they are unbalanced with an overripe flavour and heavier texture.”

Spencer Tunick was the man who organised the photography. He has plenty of experience in this field, having been organising these mass nude art pieces for more than 15 years all over the world. In 2007 he worked with Greenpeace to do one (at a cool 10 degrees C) with six hundred dedicated Swiss posing nude on a melting glacier (the Aletsch) in Switzerland. The objective, of course, to draw attention to global warming and the shrinking glaciers, although I can think of a few other shrinking things at that temperature.

In an open letter to President Obama, President Merkel and other heads of state, Greenpeace writes:

“We’re not asking you to take your clothes off in Copenhagen - but we do expect you to be there - to sign a fair, ambitious and binding deal to save the future of our planet. A half-decent climate treaty simply won’t do.”
