Recent storms cover Lake Winnipeg beach with hundreds of dead birds


After Tuesday’s storm the water of Lake Winnipeg rolled up and over Patricia Beach, leaving hundreds of dead birds behind as the water receded.

Flooding isn't just taking a toll on humans and crops, it is also impacting wildlife.

After Tuesday's storm the water of Lake Winnipeg rolled up and over Patricia Beach, leaving hundreds of dead birds behind as the water receded.

Michael Almey, who owns a cottage on Patricia Beach, said the birds covered the beach.

"They were all obviously drowned, victims of the storm, the surge of the tide," said Almey.

A naturalist on site told us the baby seagulls were too young to fly away during the storm but may have survived had the storm hit a week or two later.

Residents said conservation crews plan to start clean-up Friday.

Sea ice in Antarctic hits second all-time record in a week

A graph of the latest all-time record of Southern Hemisphere sea ice area, expressed as an anomaly.
Antarctic sea ice has hit its second all-time record maximum this week. The new record is 2.112 million square kilometers above normal. Until the weekend just past, the previous record had been 1.840 million square kilometers above normal, a mark hit on December 20, 2007, as I reported here, and also covered in my book.

Mark Serreze, director of the National Snow and Ice Data Center, responded to e-mail questions and also spoke by telephone about the new record sea ice growth in the Southern Hemisphere, indicating that, somewhat counter-intuitively, the sea ice growth was specifically due to global warming.

"The primary reason for this is the nature of the circulation of the Southern Ocean - water heated in high southern latitudes is carried equatorward, to be replaced by colder waters upwelling from below, which inhibits ice loss," Serreze wrote in an e-mail. "Upon this natural oceanic thermostat, one will see the effects of natural climate variations, [the rise] appears to be best explained by shifts in atmospheric circulation although a number of other factors are also likely involved."

Early signs of autumn in UK 'already appearing in natural world'

Sycamore seeds are well developed and hawthorn berries are already red, says National Trust

After an early spring and summer, the year is now racing towards autumn ahead of schedule, conservationists have said.

As the year reached the half-way mark, the National Trust said wildlife seemed to have come through the wettest and stormiest winter on record and nature had hurtled "helter-skelter" through the seasons since.

Now signs of autumn are already in the hedgerows and woods, National Trust naturalist Matthew Oates said.

"Looking at this year, where does it want to be? It raged its way through winter, then we went into an incredibly early spring, and then it rushed helter-skelter through spring without stopping for breath," he said.

Another global warming prediction bites the dust

The National Wildlife Federation recently warned that "Lake Erie water levels, already below average, could drop 4-5 feet by the end of this century." The announcement also warned, in a section entitled "Threats from Global Warming," that "within another 30 years Lake Superior may be mostly ice-free in a typical winter."

On Thursday, Huffington Post Canada observed that "the (Great Lakes) basin has experienced the longest extended period of lower water levels since the U.S. and Canada began tracking levels in 1918." The article blamed the lower water levels on "climate change," of course.

On, Friday, Julie Bosman at the New York Times reported a new 5-year study that concluded that "water levels in the lakes were likely to drop even farther, in part because of the lack of precipitation in recent years brought on by climate change."

Uh huh. Except that Great Lakes water levels are rising. A lot.

Ice age reboot: Ocean current shutdown viewed as culprit

The thermohaline circulation is a global ocean current that redistributes warm surface water and cold, dense deep water.
A dramatic slowdown in deep ocean currents matches a major reset in Earth's ice ages about 1 million years ago, new evidence from the South Atlantic seafloor suggests.

The discovery doesn't mean the ocean current stall-out is the only culprit behind the change in Earth's incessant ice ages, the study authors said. However, the findings provide new evidence that Earth's oceans can significantly alter its climate.

"We cannot tell for sure what broke the cycle," said lead study author Leopoldo Pena of the Lamont-Doherty Earth Observatory in New York. "Our evidence shows the oceans played a major role."

For unknown reasons, about 950,000 years ago, Earth's ice age cycles suddenly lengthened, from 41,000 years to 100,000 years. The planet's thermostat was tweaked at the same time, with ice ages growing colder than before.

Wrong time, wrong place: Rare Arctic Beluga whale seen in Massachusetts

A Beluga whale sighted in the Taunton River.
In Connecticut, we're used to seeing Beluga whales at Mystic Aquarium, but residents in Fall River, Massachusetts are getting an unusual sight in an unusual place. A Beluga whale was spotted in the Taunton River over the past several days.

"It's very rare to see a Beluga by itself this far south," Dr. Tracy Romano of Mystic Aquarium told WNPR. "It was last sighted here a week ago, on the 18th."

Romano, Mystic Aquarium's Executive Vice President of Research and Zoological Operations, is leading the team while it looks for the whale in the Taunton River. She said Belugas prefer Arctic and sub-arctic waters, and travel in pods. "This unusual sighting in our own back yard is anomalous behavior for a Beluga," she said, "and we would like to find out why."

The torrential rainfall that descended on Oslo on Thursday smashed all historical records, with a colossal 44.5mm of rain falling in just a single hour between four and five on Thursday afternoon.

Water streamed down the city's streets on Thursday afternoon, causing gridlock in much of the city centre, while hailstorms left parts of the city covered in a layer of freak summer ice.

The previous highest rainfall rate the city has seen since records began in 1937 came came in 1980, when 41.5mm of rain fell in an hour over the summer.

"It seems as though we had nearly one month's rainfall in three hours," Marit Helene Jensen told Aftenposten after the rain subsided yesterday evening.


Boy builds snowman in late June in Mörrum, southern Sweden

Sweden's meteorological agency SMHI warned of storms hitting the south on Thursday and the town of Mörrum wasn't spared.

"The hailstorm must have lasted about ten minutes and it was absolutely crazy. There was several inches of it on the ground," Göran Odenhammer, father and occasional snowman builder, told The Local.

Odenhammer and his seven-year-old son David ventured outside to inspect the hail and did what comes naturally - have fun in the snow/hail during the Swedish summer.


Ancient ocean currents may have changed pacing and intensity of ice ages

Leo Pena (above) and colleagues analyzed fossil plankton shells to reconstruct ocean circulation over the last 1.2 million years.
For decades, climate scientists have tried to explain why ice-age cycles became longer and more intense about 900,000 years ago, switching from 41,000-year cycles to 100,000-year cycles. In a new study in the leading journal Science, researchers found that the deep ocean currents that move heat around the globe stalled or even stopped, possibly due to expanding ice cover in the north. The slowing currents increased carbon dioxide storage in the ocean, leaving less in the atmosphere, which kept temperatures cold and kicked the climate system into a new phase of colder but less frequent ice ages, they hypothesize.

"The oceans started storing more carbon dioxide for a longer period of time," said Leopoldo Pena, the study's lead author, a paleoceanographer at Columbia University's Lamont-Doherty Earth Observatory. "Our evidence shows that the oceans played a major role in slowing the pace of ice ages and making them more severe."

The researchers reconstructed the past strength of earth's system of deep-ocean currents by sampling deep-sea sediments off the coast of South Africa, where powerful currents originating in the North Atlantic Ocean pass on their way to Antarctica. How vigorously those currents moved in the past can be inferred by how much North Atlantic water made it that far, as measured by isotope ratios of the element neodymium bearing the signature of North Atlantic seawater. Like a tape recorder, the shells of ancient plankton incorporate this seawater signal through time, allowing scientists to approximate when the currents grew stronger and weaker off South Africa.

They confirmed that over the last 1.2 million years, the conveyor-like currents strengthened during warm periods and weakened during ice ages, as previously thought. But they also discovered that at about 950,000 years ago, ocean circulation weakened significantly and stayed weak for 100,000 years; during that period the planet skipped an interglacial - the warm interval between ice-ages - and when the system recovered it entered a new phase of longer, 100,000-year ice age cycles. After this turning point, the deep ocean currents remain weak during ice ages, and the ice ages themselves become colder, they find.
