Here are the top environmental links folks are Digging today:

• The Associated Press: "Scientists eye unusual swarm of Yellowstone quakes"

— Yellowstone has been set to vibrate for the last three days, as more than 250 tremors have kept the earth shaking and scientists guessing. "This is an active volcanic and tectonic area, and these are the kinds of things we have to pay attention to," a park seismologist told the AP. Yellowstone is the caldera of a volcano that last erupted 70,000 years ago.

• Deltoid: "Denialists scraping the bottom of the barrel"

— ScienceBlogs' Deltoid mocks the logical fallacies of global warming denier Christopher Booker, who seems to infer in a Telegraph column today that winter and an economic recession disprove manmade global warming.

The Telegraph [video]: "Great white shark circles kayakers and fishermen in Sydney"

— A newly released video shows kayakers in Australia being surprised by a great white shark, which circled their boat and at one point bumped into it, knocking one of the men into the water. He had to tread water while the shark circled him for a minute until he was rescued.

• "Malaysia uses satellite to fight illegal logging: report"

— Facing rapidly dwindling forests — 13 percent were lost in the 1990s alone — Malaysia is launching a program to spy on its forests via satellite, looking for illegal logging, land clearing and fires.

The Daily Mail: "Chilling game of hide and seek with a hungry polar bear"

— In a scary but inevitably amusing set of images, a man in Barrow, Alaska, is cartoonishly chased in circles around a pickup truck by a presumably hungry polar bear. He suffered more than 100 deep scratches but finally scrambled into another truck that was unlocked.
