Canada: Alberta's bees dying at record rates

For the second year in a row, Alberta beekeepers are hearing less buzzing from their hives.

A pest manager with the provincial government says bee populations in over-wintered colonies are down by 25 per cent -- 10 per cent more than normal.

Honey farmer Ernie Martens, who normally runs 1,000 hives in northern Alberta, estimates he's lost 70 per cent of his insects.

"We're trying to figure out ways to rebuild, but I'm not sure how," he said from his farm in La Crete, which is about 800 kilometres north of Edmonton.

US: 25-Thousand Bees Invade Jersey County School

Spring has sprung and bees are buzzing. Brighton Illinois beekeeper Gene Reilley spends a lot of time hunting for swarms of bees. This week he scooped up 25 thousand bees from the 5th grade classroom at Delhi Elementary school in Jersey County.

Students weren't frightened. One said, "Cool very cool." Another, "There was a lot of bees."

Students were removed from the classroom when the bees moved inside through a crack in the wall which has since been sealed. No children were hurt.

Germany Suspends Pesticide Approvals After Mass Death Of Bees

The German Office for Consumer Protection and Food Safety (BVL) has reportedly suspended the approval for eight pesticides after the mass death of bees in one state.

The German Research Centre for Cultivated Plants reported that 29 out of 30 dead bees it examined in Germany's Baden-Wuerttemberg state had been killed by contact with clothianidin, a product found in one of the seed treatment products.

The suspended products are: Antarc (ingredient: imidacloprid; produced by Bayer), Chinook (imidacloprid; Bayer), Cruiser (thiamethoxam; Syngenta), Elado (clothianidin; Bayer), Faibel (imidacloprid; Bayer), Mesurol (methiocarb; Bayer) and Poncho (clothianidin; Bayer).

Vast cracks appear in Arctic ice

Dramatic evidence of the break-up of the Arctic ice-cap has emerged from research during an expedition by the Canadian military.

Scientists travelling with the troops found major new fractures during an assessment of the state of giant ice shelves in Canada's far north.

The team found a network of cracks that stretched for more than 10 miles (16km) on Ward Hunt, the area's largest shelf.

Dramatic Impact Of Sea-Level Rise On Chesapeake Bay's Coastal Habitats

A new report, Sea-Level Rise and Coastal Habitats of the Chesapeake Bay, shows in vivid detail the dramatic effects of sea-level rise on the largest estuary in the US, which sustains more than 3,600 species of plants, fish and animals including great blue herons and sea turtles.

Sharks face extinction in world's oceans

Sixteen out of 21 oceanic shark and ray species, which are caught for their valuable fins and meat, face the threat of extinction, the IUCN Shark Specialist Group (SSG) said on Friday.

The SSG cited a study conducted by 15 scientists from 13 research institutes around the world.

Thresher sharks, silky sharks, short-fin mako, and the great white shark are under particular threat as they take a long time to mature and reproduce. Scientists have warned that the current trend could upset the overall balance of the marine environment.

Scientists Show Off California Fault Stress

HAYWARD -- The U.S. Geological Survey (USGS) conducted a walking tour on Thursday in Hayward, showing off the stress that is building up on the Hawyard Fault. USGS scientists say the Hayward fault is predicted to be the most likely fault in the Bay Area to generate a major earthquake by 2032. The fault runs from the South Bay to San Pablo Bay. The last major earthquake on the fault occured in 1868, though several small earthquakes have shaken the East Bay in recent months.

Scientists say the stress building up on the fault is visible. There are cracks in concrete and in some places, offset of 3 to 4 inches. There is a virtual tour set up on the USGS website showing areas under going stress.

Disaster Earthquake Scenario Unveiled For Southern California

Scientists have unveiled a hypothetical Scenario describing how a magnitude 7.8 Southern California earthquake - similar to the recent earthquake in China - would impact the region, causing loss of lives and massive damage to infrastructure, including critical transportation, power, and water systems.
