Six Degrees: Our Future on a Hotter Planet A free talk on climate change by Mark Lynas author of 'High Tide' and 'Carbon Counter', as well as writer for the Times, Guardian & Independant. Monday June 18th 6pm to 7pm • Special menu at the Warehouse Cafe. Bookings are available (call 0121 633 0261). Enjoy a meal in the company of Mark Lynas. Booking signing will also take place. 7pm to 8pm • Mark Lynas presents his talk at Journey’s Metropolitan Community Church, (opposite the Warehouse Cafe and Birmingham Friends of the Earth) followed by a short Q&A. 8pm to 9pm• Post-talk book signing will take place at the Warehouse Cafe. What it is about Scientists predict that global temperatures will rise by between one and six degrees over the next century. But what will these temperature rises actually mean? For the first time, Mark Lynas brings together the major scientific projections, degree by degree, showing how life will change on a hotter planet. He reveals why the western US, southern Europe and Australia are likely to become uninhabitable. He shows the chaos and destruction that will result unless urgent action is taken to cut back greenhouse gas emissions, and he explains how we can avoid the worst impacts. It makes a sobering talk. But Forewarned is forearmed. Detail from the author Like many who watched the hurricane disaster strike New Orleans last year, I was shocked at the deprivations endured by the victims – left to fend for themselves in terrible conditions in the world’s richest country. It was shocking in itself, but I also felt something else: that this was a window into the future, a glimpse of what may be in store for us all if nothing is done about global warming. I kept wondering: where next? How and what will happen as the world warms bit by bit? With up to six degrees of global warming on the cards over the next hundred years, according to the Intergovernmental Panel on Climate Change (IPCC), what will happen to our coasts, our towns, our forests, our rivers, our croplands and our mountains? Will we all, as some environmentalists suggest, be reduced to eking out a living from shattered remains of civilisation in Arctic refuges, or will life go on much as before – only a little warmer? Hence my Six Degrees project, which was published as a book in March 2007 by Fouth Estate (HarperCollins). Over the last two years I have sifted through thousands of scientific papers, published in dozens of academic journals, each with a prediction which is relevant to the century ahead. I categorised them all by degree, and on the basis of this unique compendium of data began to write chapters, each telling the story of how our world will change with each degree of global warming. Here are summaries of the first three chapters – to see how it ends, you’ll have to buy the book itself. You can buy it on the night. (You can also read a degree-by-degree outline, published on the front page of the Independent newspaper on 3 February 2007, which uses some of the material to be published in the book, and see a brief glimpse of the ‘six degree world’, also as published in the Independent.) One DegreeDeserts invade the High Plains of the United States, in a much worse repeat of the 1930s dustbowl. Whilst the epicentre is Nebraska, states from Canada in the north to Texas in the south suffer severe agricultural losses. Mount Kilimanjaro loses all its ice. The Gulf Stream switches off – perhaps, plunging Britain and Europe into icy winter cold. Irreversible feedbacks take hold in the Arctic as ice disappears, and the permafrost line shifts north. Rare species wiped out in the Queensland rainforest, Australia. Coral reefs around the world suffer increasing losses from bleaching and are wiped out. Coral atolls submerge under the rising seas. Two DegreesOceans turn increasingly acidic, wiping out calcareous plankton and further hitting surviving coral reefs – much of the marine food chain endangered. One summer in every two has heatwaves as strong as the 2003 disaster in Europe, when 30,000 died. Drought, fire and searing heat strikes the Mediterranean basin. Greenland tips into irreversible melt, accelerating sea-level rise and threatening coastal cities around the world. Hundreds of millions live in peril of the rising seas. Polar bears, walrus and other ice-dependent marine mammals extinct in the Arctic. Glaciers in Peru disappear, threatening water supplies to Lima. Declining snowfields also threaten water supplies in California. A third of species worldwide face extinction as the climate changes – the worst mass extinction since the end of the dinosaurs. Three DegreesThe Kalahari desert spreads across Botswana, engulfing the capital in sand dunes, and driving millions of refugees out to surrounding countries. A permanent El Nino grips the Pacific, causing weather chaos around the world, and drought in the Amazon. The whole Amazonian ecosystem collapses in a conflagration of fire and destruction – desert and savannah eventually take over where the world’s largest rainforest once stood. Huge amounts of carbon pour into the atmosphere, adding another degree to global warming. Water runs short in Perth, Sydney and other parts of Australia away from the far north and south. Hurricanes strike the tropics half a category stronger than today’s, with higher windspeeds and rainfall. Agriculture shifts into the far north – Norway’s growing season becomes like southern England is today. But with declines in the tropics and sub-tropics due to heat and drought, the world tips into net food deficit. The Indus river runs dry due to glacial retreat in the Himalayas, forcing millions of refugees to flee Pakistan. Possible nuclear conflict with India over water supplies.
