Climate Change 'Will Cause Civilisation to Collapse

By Jonathan Owen for The Independent/UK

Authoritative new study sets out a grim vision of shortages and violence – but amid all the gloom, there is some hope too

An effort on the scale of the Apollo mission that sent men to the Moon is needed if humanity is to have a fighting chance of surviving the ravages of climate change. The stakes are high, as, without sustainable growth, "billions of people will be condemned to poverty and much of civilisation will collapse".

This is the stark warning from the biggest single report to look at the future of the planet - obtained by The Independent on Sunday ahead of its official publication next month. Backed by a diverse range of leading organisations such as Unesco, the World Bank, the US army and the Rockefeller Foundation, the 2009 State of the Future report runs to 6,700 pages and draws on contributions from 2,700 experts around the globe. Its findings are described by Ban Ki-moon, Secretary-General of the UN, as providing "invaluable insights into the future for the United Nations, its member states, and civil society"

Permafrost Melting a Growing Climate Threat

From Reuters

SINGAPORE - The amount of carbon locked away in frozen soils in the far Northern Hemisphere is double previous estimates and rapid melting could accelerate global warming, a study released on Wednesday says.

Large areas of northern Russia, Canada, Nordic countries and the U.S. state of Alaska have deep layers of frozen soil near the surface called permafrost.

Global warming has already triggered rapid melting of the permafrost in some areas, releasing powerful greenhouse gases carbon dioxide and methane.

As the world gets warmer, more of these gases are predicted to be released and could trigger a tipping point in which huge amounts of the gases flood the atmosphere, rapidly driving up temperatures, scientists say.

"Massive amounts of carbon stored in frozen soils at high latitudes are increasingly vulnerable to exposure to the atmosphere," said Pep Canadell, executive director of the Global Carbon Project at Australia's state-funded Commonwealth Scientific and Industrial Research Organisation.

"The research shows that the amount of carbon stored in soils surrounding the North Pole has been hugely underestimated."
