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.

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.

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.

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.

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.

Heavy rain and hailstones hit Tokyo and surrounding areas on Tuesday. Tokyo's Mitaka City was hit by hail in the afternoon. Some residents say that hailstones of up to 3 centimeters wide fell for about 30 minutes.

It covered residential areas, accumulating up to 10 centimeters. Residents used shovels to remove it from around their homes.

Weather officials say that warm, humid air and a cold air mass made atmospheric conditions unstable, causing cumulonimbus clouds to develop over Tokyo area. Some clouds were more than 10 kilometers high. Powerful updrafts occurred, and that lead to the hailstorm.

An early freeze in the Great Plains may cut corn production by 8%, according to Simon Atkins, CEO of Advanced Forecasting Corporation, who presented his long-range forecast in a webinar on Monday.

The cause: above-average volcanic eruptions around the world for the last nine months, including three in the last month - in Eastern Russia, Alaska and Indonesia. The release of sulfur into the atmosphere from volcanic eruptions reflects sunlight back out to space.

The meteorologist predicted cooler-than-normal summer temperatures "because of well-above-normal volcanic eruptions going back to the fall of 2013. We are not going to see many hot periods. Sure, there will be a few days here and there where temperatures reach 100 degrees in Oklahoma, but it's not going to be very common."

"What's going to be more common is more moisture coming in off the Eastern seaboard of the U.S., and it will be pushing frontal boundaries from east to west, cooling down even parts of the Midwest in July and August," he continued. "We think the first two weeks of September will be warmer. But then it will be getting quite a bit colder toward the end of September, and even into October."

These cooler temperatures could damage the corn crop, Atkins explained.

"We think there's going to be an early frost [in the Plains west of Kansas], which could reduce the number of bushels per acre of corn - maybe by around 8%, our current rate of prediction," he said. "It will be a killing freeze, at least 10 to 15 days earlier than normal."

Meanwhile, Atkins expects flash flooding in the Midwest this week, from Nebraska down to Arkansas, even reaching into parts of the Tennessee River Valley. "Some of these winds will reach 80 miles per hour with hail, producing lots of flash flooding. Some fields in the Midwest will suffer from too much rain," he said.

The northern Norwegian city of Tromso experienced a freak summer snowfall on Monday after freezing wind from the North Pole saw temperatures plummet.

It was the first time since records began that the city had seen snowfall in June. Local meteorologist Trond Lien said that sleet and snow showers hit the city on Monday night, and there has even been some snow lying on the ground. He said that the situation was "very rare", noting that it must have been a long time since it snowed on 16 June. He added that he had found records showing that Tromso had experienced snowfall in July, but he could find nothing to indicate snow in June.

Motorist Odd Arne Thomassen told reporters that he was driving over roughly four centimetres of snow when he was in Kvaenangsfjellet, in North Troms, early on Monday morning. He explained that it was not bad enough to make him feel he needed his chains on, but that there was certainly about four centimetres lying on the ground.

Yr.no, the weather forecasting venture between the Meteorological Institute and TV station NRK, predicted that other areas of the country would also experience snowfall. It said that high-lying areas of western and southern Norway would likely see snow, despite the fact that the capital Oslo is lapping up temperatures in excess of 20C.
