Ocean Acidification is Accelerating and Severe Damages are Imminent

Urgent action is needed to limit damages to marine ecosystems, including coral reefs and fisheries, due to increasing ocean acidity, according to 155 of the world's scientific experts who will release the Monaco Declaration this Friday.

The Declaration is based on results from the Second International Symposium on the Ocean in a High-CO2 World, held at the Oceanography Museum in Monaco last October and organised by the International Geosphere-Biosphere Programme (IGBP), UNESCO's Intergovernmental Oceanographic Commission, the Scientific Committee on Oceanic Research (SCOR) and the International Atomic Energy Agency (IAEA).

The ocean absorbs a quarter of the carbon dioxide emitted into the atmosphere from human activities. Observations from the last 25 years show increasing acidity in surface seawater, following trends in increasing atmospheric CO2.

Australian heatwave claims homes, lives

Australia's second-largest city Melbourne ground to a halt on Saturday, crippled by a once-in-a-century heatwave that has claimed almost 30 lives and razed at least 17 homes.

Wildfires raged through the southeastern state of Victoria, where authorities said flames had come dangerously close to major electricity transmission lines which supplied power to Melbourne on Saturday.

More than 500 000 homes and businesses in Melbourne were left without power on Friday night after an electrical substation exploded in the heat, bringing the city to a standstill. Temperatures in Victoria topped 43°C for a record-breaking third consecutive day on Friday, when 10 homes and a timber plantation were destroyed in a 6 500 hectare blaze.

"Immortal" Jellyfish Swarm World's Oceans

© Stefano Piraino and Maria Pia Miglietta Turritopsis dohrnii, a potentially "immortal" jellyfish species that can age backward, is silently invading the world's oceans.
A potentially "immortal" jellyfish species that can age backward - the Benjamin Button of the deep - is silently invading the world's oceans, swarm by swarm, a recent study says.

Like the Brad Pitt movie character, the immortal jellyfish transforms from an adult back into a baby, but with an added bonus: Unlike Benjamin Button, the jellyfish can do it over and over again - though apparently only as an emergency measure.

About as wide as a human pinky nail when fully grown, the immortal jellyfish (scientific name: Turritopsis dohrnii) was discovered in the Mediterranean Sea in 1883. But its unique ability was not discovered until the 1990s.

South Aftrica: A shark in our river? Dead right for the ecosystem

Cape Town - Cool-headed Witsand residents have accepted their toothy marine neighbour with some pride and are not about to be scared away from their beloved Breede River by any shark, big or small, they say.

Witsand hit the headlines this week when a four-metre female Zambezi shark, heavily pregnant with at least four pups, was caught 5,5km upriver from the fishing village.

Locals said they were more amazed than frightened at the appearance of the shark, estimated to weigh about 650kg.


Mature Arctic Ivory Gull spotted In Massachusetts for first time in over a century

The temperatures were in the single digits, but not low enough to keep the gawkers away. A celebrity was in town, behind the East Bay Grille, a visitor not seen in these parts in decades, if not longer.

But these weren't paparazzi, and this wasn't a Hollywood star. Rather, they were avid birdwatchers - about 20 in all - braving the frigid air as they scanned the bay and the edges of the breakwater with binoculars and spotting scopes.

Alaska Volcano Expected to Erupt Soon

In the shadows of Mount Redoubt, Alaskans are calmly waiting for the volcano to erupt -- an event that could occur at any time.

"The level of seismic activity" has "increased markedly" in recent days at the 10,197-foot peak located about 100 miles southwest of Anchorage, the state's most populous city, according to the Alaska Volcano Observatory.

"We don't have a crystal ball," said Peter Cervelli, a research geophysicist with the observatory, which is aggressively monitoring the volcano.
