CO2 emissions rise beyond worst expectations
Barely a month ahead of the UN climate summit in Durban, new figures show that global CO2 emissions a rising at record pace. The grim numbers from the US Department of Energy say the amount of carbon dioxide pumped into our atmosphere in 2010 was 6 percent higher than the year before.
6 percent doesn’t sound much? Well, it corresponds to more than half a billion metric tons of CO2 extra! Or, as a commentator on this blog puts it “We’re really flooring the accelerator as we approach the cliff”

7 billion, and counting
There are now more than 7 billion people living on our planet! It’s a reason to celebrate and a stark reminder of how many people live and depend on the planet’s resources. Human population looks like it will continue to grow at breakneck speed, and that means it’s vital we make sure the earth can meet the needs of all 7, 8 or even 9 billion people – when we get to that point.
Climate change poses the biggest threat to meeting the basic food supply needed to nourish the world. Severe weather, changing rain trends and other turnarounds in global climate patterns have put important basic crops at risk – from wheat and corn to coffee. As the supply falls, the prices for food soar, making it too expensive for many in the world’s developing countries.
On top of that, more people means more energy use, and the need for clean, eco-friendly energy on a wide scale will become even more crucial in the coming years. So you’re now one of more than 7 billion people on the planet. What can every person do to keep the world safe?

Turning orange peel into plastic?
Next time you eat an orange, think twice about chucking the peel into a bin – it might just help generate low-carbon plastic or energy in the future. An international group of scientists has come up with an innovative way of recycling food waste such as orange peel or coffee grounds.
Researchers at the universities of York, Sao Paulo and Cordoba have found that high-powered microwave heating can help activate cellulose in a variety of food waste, triggering the release of several chemicals. These include limonene, used in various household chemicals, and bio-ethanol which can be used as a substitute for diesel fuel. These chemicals could ultimately be used to make many of the chemicals and materials that we currently need oil for. And it could help tackle the growing problem of food waste.
The project called OPEC, or the Orange Peel Exploitation Company, plans to tie up with the juice-making industry in Brazil, a huge producer of orange peel residue. As a first step, there are plans to build a pilot plant in York that would process about 10 kilograms of waste per hour.

Melt! is Europe’s largest indie and electro music festival. Taking place in July every year, the 2011 installment saw 150 DJs and bands perform in front of a 20,000 strong crowd. When the music plays the heat is on. That’s not always a good thing: instruments, lighting, logistics plus thousands of fans camping out on site are gobbling up huge amounts of energy. The CO2-emissions of the 3-day event are on a par with that of a small town. But this year climate protection is part of the act. Find out how in our latest GI report.
In addition here are interviews on the issue with some of the artists. Daniel of projecthires.com has quizzed the Melt!-line up about climate change and the need for action.
