As the world has talked for a dozen years about what to do next, new ship passages opened through the Arctic's once-frozen summer sea ice. In Greenland and Antarctica, ice sheets have lost trillions of tons. Mountain glaciers in Europe, South America, Asia and Africa are shrinking faster than before.

Climate Roulette

They say that everyone who finally gets it about climate change has an "Oh, shit" moment--an instant when the full scientific implications become clear and they suddenly realize what a horrifically dangerous situation humanity has created for itself. Listening to the speeches, groundbreaking in their way, that President Obama and Chinese President Hu Jintao delivered September 22 at the UN Summit on Climate Change, I was reminded of my most recent "Oh, shit" moment.

By Gerard Wynn Gerard Wynn – Tue Sep 29, 3:14 pm ET OXFORD, England (Reuters) – A rise of at least two meters in the world's sea levels is now almost unstoppable, experts told a climate conference at Oxford University on Tuesday. "The crux of the sea level issue is that it starts very slowly but once it gets going it is practically unstoppable," said Stefan Rahmstorf, a scientist at Germany's Potsdam Institute and a widely recognized sea level expert.

Climate researchers now predict the planet will warm by 6.3 degrees Fahrenheit by the end of the century even if the world's leaders fulfill their most ambitious climate pledges, a much faster and broader scale of change than forecast just two years ago, according to a report released Thursday by the United Nations Environment Program.

New NASA Research May Show "Runaway" Ice Melt Has Begun

Submitted by glenshewchuck on

The most optimistic view about Greenland and Antarctica ice melt is now off the table, and the worst case scenario about accelerating, self-perpetuating ice melt is front and center in climate science, according to science experts, reacting to news about fresh NASA-funded research being published in Nature this week. What does this mean for renewable energy start-ups? Start more companies and faster, would be the logical implication for the sector.

How Much Human Activity Can Earth Handle?

The scientific name is the Holocene Age, but climatologists like to call our current climatic phase the Long Summer. The history of Earth's climate has rarely been smooth. From the moment life began on the planet billions of years ago, the climate has swung drastically and often abruptly from one state to another — from tropical swamp to frozen ice age. Over the past 10,000 years, however, the climate has remained remarkably stable by historical standards: not too warm and not too cold, or Goldilocks weather.

Scientists Believe the True Cost of Climate Change Is Far Higher Than Anticipated

Scientists, led by Professor Martin Parry, the former co-chair of the Intergovernmental Panel on Climate Change, are set to warn that the UN negotiations aimed at combating climate change are based on unachievable low costs. The real costs are likely to be 2-3 times greater than estimates set out by the UN Framework Convention on Climate Change, according to a new report published by the International Institute for Environment and Development and the Grantham Institute for Climate Change at Imperial College London.
