7 Tipping Points That Could Transform Earth

Show

When the Intergovernmental Panel on Climate Change issued its last report in 2007, environmental tipping points were a footnote. A troubling footnote, to be sure, but the science was relatively new and unsettled. Straightforward global warming was enough to worry about. But when the IPCC meets in 2014, tipping points — or tipping elements, in academic vernacular — will get much more attention. Scientists still disagree about which planetary systems are extra-sensitive to climate shifts, but the possibility can’t be ignored. ... Read more about 7 Tipping Points That Could Transform Earth

The Copenhagen Diagnosis

Show

Authors of the landmark 2009 climate report "The Copenhagen Diagnosis" estimate that by 2020 industrial nations must reduce their greenhouse gas emissions by around 40% below 1990 levels to secure a decent chance of avoiding dangerous human interference with the climate system. ...

Climate Change Speeds Up Since 1997 Kyoto Accord

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

Show

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. ...

Two Meter Sea Level Rise Unstoppable-Experts

Show

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. ...

New Analysis Brings Dire Forecast Of 6.3-Degree Temperature Increase

Show

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

Show

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?

Show

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. ...
