As food prices spike again, aid agency warns cost of staples will double in 20 years

As food costs spike for the second time in three years, an international aid agency predicts the price of some staples such as corn will double in the next 20 years amid a permanent crisis caused by rising demand, flat crop yields and climate change.

The report by Oxfam released Tuesday said the demand for food will grow 70 to 90 per cent by 2030, without factoring in the impact of climate change. Increasingly frequent droughts, floods and changes in agricultural patterns from global warming will add pressure to what the agency calls an already broken system.

Hundreds of dead seals in Labrador

[via news.sympatico.cbc.ca]

People on the north coast of Labrador say scores of dead seals have been washing ashore since early December.

A conservation officer with the area’s Inuit government estimated late last week that hundreds of adult and young seals have died in the area between Hopedale and Makkovik this winter.

The Department of Fisheries and Oceans (DFO) is testing the carcasses, but Nunatsiavut conservation officer Ian Winters said many people in the area believe DFO hasn’t acted quickly enough.

EU: No More Illegal Timber

Posted by Nexus – 08/06/2010

Right now European institutions are deciding on legislation that would ban illegal timber, which devastates forests and enriches organized crime. But certain member states with large timber industries are blocking negotiations.

Within days, the European Union could ban illegal timber from entering the market — but powerful companies are blocking discussions.

Forests are the habitat and life source of many peoples and are essential in preventing climate change, but while there is high demand for timber, illegal logging thrives, killing species, and fuelling corruption and organized crime.

Secrets of Antarctica’s 15-Million Year-Old Lake

Posted by Nexus – 19/03/2010

Researchers have thawed ice estimated to be perhaps a million years old or more from above Lake Vostok, an ancient lake that lies hidden more than two miles beneath the frozen surface of Antarctica using novel genomic techniques to determine how tiny, living “time capsules” survived the ages in total darkness, in freezing cold, and without food and energy from the sun.

Lake Vostok is located beneath four kilometers of ice in East Antarctica. The lake is approximately 250 km long and 50 km wide. The overlying ice provides a continuous paleo-climatic record of 400,000 years, although the lake water itself may have been isolated for as long as 15 million years.

A strong, 6.6 magnitude earthquake hit northern Japan Sunday afternoon, said the Japanese government, which did not issue a tsunami warning.

The quake happened at 5:08 pm (0808 GMT) off the Pacific coast of Fukushima prefecture, the Japanese Meteorological Agency said.

“It is possible that the tidal level would change slightly. But there is no worry about damage,” the agency said.

Some train services automatically stopped immediately after the quake, before resuming normal operations.

Pillar at Sunset

Reddened light from the setting Sun illuminates the cloud banks hugging this snowy, rugged terrain.

Inspiring a moment of quiet contemplation, the sunset scene included a remarkable pillar of light that seemed to connect the clouds in the sky with the mountains below. Known as a Sun pillar, the luminous column was produced by sunlight reflecting from flat, six-sided ice crystals formed high in the cold atmosphere and fluttering toward the ground.

Last Monday, astronomers watched this Sun pillar slowly fade, as the twilight deepened and clearing, dark skies came to Mt. Jelm and the Wyoming Infrared Observatory.

Animation of Giant Iceberg Collision as Seen From Space

The collision in early February of the 60-mile-long B-9B iceberg with the protruding tongue of the Mertz Glacier in East Antarctica is captured here in a series of satellite radar images.

The crash created a second massive iceberg nearly 50 miles long and 25 miles wide, named C-28. The name means that it’s the 28th glacier since 1976 that has broken off from the quadrant of Antarctica that faces Australia.

Days Get Shorter Because of Chilean Earthquake

Posted by Nexus – 02/03/2010

[via gizmodo.com]

Apart from a colossal tsunami, here’s another effect of the 66.6 exajoules liberated by this weekend’s earthquake in Chile: NASA’s Jet Propulsion Laboratory says that days will now be shorter because the quake shifted Earth’s axis by three inches.

The change—which can only be measured thanks to computer models—will result in days that are 1.26 microseconds shorter than before. That’s 0.00000126 seconds shorter. There may have been more visible changes, like islands changing its position. One of them, Santa María, may have raised two meters after the shattering land move.

Chile earthquake: tsunami fears as death toll hits 147

Posted by Nexus – 27/02/2010

[via telegraph.co.uk]

At least 147 have been killed and nearly a quarter of the globe put on urgent tsunami alert after one of the most powerful earthquakes of modern times hit South America.

A tremor with a magnitude of 8.8 devastated large parts of southern Chile and sent huge waves racing at up to 400 miles an hour across the Pacific. Isolated ocean islands were reported to have suffered severe wave damage, and tsunami warnings were issued across a vast area stretching from Russia and Japan through to the Philippines and New Zealand.
