Power Shift is Australia’s first national youth climate summit. It’s the moment where our fast-growing youth movement for a safe climate future comes together.

Power Shift 2009 will leverage the momentum AYCC member groups - all of Australia’s biggest youth organisations - have built through their various programs and campaigns. We’re taking our movement beyond our schools, campuses and youth organisations to Sydney to demand - and create - a power shift to renewable energy, green jobs and safe cl

The world’s first ‘full scale’ floating wind turbine has been installed off the Norwegian coast by Statoil Hydro.

The 2.3 Megawatt turbine has 100 metres of ballast below the water to support the massive structure. It is expected to generate enough green electricity for the equivalent of 1600 UK homes.

Power Shift is happening in Sydney from July 11-13.

World Environment Day on Friday sees the worldwide release of a movie billed by producers as "the greatest green event ever", a high-budget documentary to save the planet from Yann Arthus-Bertrand.

This animation explains the carbon cycle and humans' conbritution to it.

Warming Arctic temperatures could lead to the release of significant methane emissions from thawing permafrost and marine deposits.

"Reducing our carbon emissions requires the deployment of multiple, diverse clean energy projects that can reliably supply secure power to the electrical grid. By developing efficient systems that drive down the cost of solar, BrightSource Energy’s solar thermal technology is playing a vital role."

As fossil fuels and shrinking forests overload the atmosphere with excess carbon, what part can soils play in a solution to global warming?

The answer may lie beneath the rainforests of central Amazon, in yellow soils long ago turned black known by the locals as terra preta.

Visiting Australia last week, US writer Bill McKibben spoke about "350.org", an environmental organisation he has founded to urge people around the world to take action on what he regards as an urgent situation.

Thousands of climate scientists agree that global warming is not only the most threatening environmental problem, but one of the greatest challenges facing all of humanity. We must demand a separation between oil and state. We can get off oil and slow down global warming. We can use energy more efficiently, and support renewable, clean energy sources; new green technologies that don't burn carbon, like hydrogen fuel cells, wind and solar power. We can vote for leaders who care about protecting your health,

No more than 350 parts per million is the safe concentration of carbon dioxide in the atmosphere for the planet. We are currently at 387 and rising.
