My recent articles only touch on some of the significant problems with fracking. There’s more to come. (And check out trailer for the new fracking movie starring Matt Damon http://bit.ly/TC8qNB) —  Stephen

UPDATE Jan 2013:

Yet another study reveals fracking has a huge problem of gas leaks. Up to  9% of the gas pumped out of the ground leaks into the atmosphere according to a study by National Oceanic and Atmospheric Administration (NOAA) published in Nature this week. Natural gas (methane) is a powerful greenhouse gas. If these leaks are widespread, fracking is worse than burning coal, accelerating global warming.

In Jan 2012 I detailed new research in the article below showing that replacing coal with natural gas from fracking does little to fight climate change (see below). Now two studies published that since then make an even stronger case that fracking for natural gas is a HUGE MISTAKE:

From Nature: Air sampling reveals high emissions from gas field. Methane leaks during production may offset climate benefits of natural gas.

From Environmental Research Letters: New study demonstrates switching to natural…

Ethanol, biofuel, oil palm, biodiesel and why they’re pushing up food prices, mostly bad for the environment and just a dumb bad idea. — Stephen

“The U.S. has led the fight to stem global hunger, now we are creating hunger,” said Lester Brown, president of the Earth Policy Institute.

Series of the latest articles that provide almost everything you need to know about why ethanol and biofuels will not reduce global warming but simply drive up fuel and food costs.

Ocean Acidification Leaves Mollusks Naked and Confused

When the carbon dioxide absorbed by the oceans dissolves in seawater, carbonic acid is formed and calcium carbonate, vital for the formation of the skeletons and shells of many marine organisms, becomes scarcer.

MONTEREY, California, Oct 2 2012 (IPS) –

Climate change will ruin Chilean sea snails’ ability to sniff out and avoid their archenemy, a predatory crab, according to Chilean scientists who presented their findings at an international science symposium here.

Researchers from Australia also revealed that as the oceans become more and more acidic, some fish become hyperactive and confused, and move towards their predators instead of trying to escape.

“The conditions in oceans are changing 100 times faster than at any time in the past,” said Jean-Pierre Gattuso, a marine biologist with CNRS-INSU and the Laboratoire d’Océanographie de Villefranche in France.

Climate change is making oceans warmer and more acidic. “We are beginning to understand what will happen. I think we can expect the worst,” Gattuso told Tierramérica*.

Connecting dots: extreme weather to oil, gas, coal

+15,000 temperature records already broken in the US this year 

By Stephen Leahy

UXBRIDGE, Canada, May 4, 2012 (IPS)

What are you doing on Saturday? Peter Nix, a retiree, will be standing on a railway track on Canada’s west coast blocking a coal train destined to ship U.S. and Canadian coal to Asia.

Nix will be joined by dozens of people near White Rock, British Columbia on May 5. They will be in good company as tens of thousands of people around the world participate in global day of action to “connect the dots” between climate change and extreme weather.

“There will be at least 1,200 actions in more than 100 countries,” says Jamie Henn, communications director for 350.org, a U.S.-based environmental group.
