Tornadoes in January! Wide area of U.S. faces unusual early threat

A wide area of the central and southeast U.S. faces the unusual threat of tornadoes in January over the next 12 to 18 hours as an approaching cold front clashes with unusually warm air, a meteorologist said on Tuesday.

The first tornado warning of the approaching storm was issued on Tuesday for western Missouri, said meteorologist Bill Bunting at the National Weather Service Storm Prediction Center in Norman, Oklahoma.

A warning is intended to signal residents to take cover because a tornado could be forming. A less urgent tornado watch is in effect for a region from extreme northeast Texas through virtually all of Arkansas, western Tennessee and extreme southern Illinois.

"It's a little unusual," Bunting said of the tornado threat. "We don't see this every winter with this kind of warmth preceding a storm system."

Snow, hail, heavy rain and thunder - the North Somerset area has experienced it all over the past two weeks.

And now the wild weather has caused a spectacle in the Bristol Channel, with local people capturing a picture of what appears to be a mini tornado in the estuary.

This picture was taken by Sue Hewitt, of Downend, who spotted the event while out walking along the coastal path between Clevedon and Portishead at around 1pm on Sunday.

Coral reefs going through 'extremely alarming' decline in the Caribbean

Coral reefs in the Caribbean are producing less than half of the key ingredient that makes their calcium skeleton compared to pre-industrial times, scientists said on Tuesday, describing the findings as "extremely alarming."

The amount of new calcium carbonate being added by coral reefs is at least half, and in some places 70 percent lower, than it was thousands of years ago.

Biologists have long sounded the alarm for reef-building corals, on which nearly half a billion people depend for their livelihood from fishing and tourism.

Previous research has estimated that coral cover is declining by as much as two percent per year in parts of the Indian Ocean and the Pacific. In the Caribbean, cover has shrunk by around 80 percent on average since the mid-1970s.

Report shows vast forest, shared by India and Bangladesh, is being rapidly destroyed by environmental change

A vast mangrove forest shared by India and Bangladesh that is home to possibly 500 Bengal tigers is being rapidly destroyed by erosion, rising sea levels and storm surges, according to a major study by researchers at the Zoological Society of London (ZSL) and others.

The Sundarbans forest took the brunt of super cyclone Sidr in 2007, but new satellite studies show that 71% of the forested coastline is retreating by as much as 200 metres a year. If erosion continues at this pace, already threatened tiger populations living in the forests will be put further at risk.

Enormous sinkhole swallows buildings in Guangzhou, China

Several buildings have fallen into an enormous sinkhole in Guangzhou, China, destroying at least five shops and taking out power for 3,000 residential units nearby, Shanghaiist reports.

The sink hole was 300 square meters wide (3229.2 square feet), and appears to be growing. Thankfully there does not appear to be any injuries at present.

This video shows the moment the sinkhole expanded, taking out much of the building and creating a chaotic scene.


Comment: We find it interesting that the number of sinkholes are increasing... is the planet literally 'opening up'?

Sea change: The Bay of Bengal's vanishing islands

Rapid erosion and rising sea levels are increasingly threatening the existence of islands off the coast of Bangladesh and India

School teacher Nurul Hashem lives in a grass hut set among coconut palms and pine trees, just yards from a pristine beach on the sparkling Bay of Bengal. It sounds idyllic, but he longs to return to the island of Kutubdia, 50 miles away, where his family home has been swallowed by ever-rising tides and is now out at sea under several feet of water.

To make matters worse, the local government, which welcomed him when he arrived three years ago, wants him and thousands of other families who have fled to the coast from the island, to make way for an airport and hotel developments.

Kutubdia is one of many islands off Bangladesh and India affected by increasingly rapid erosion and some of the fastest recorded sea-level rises in the world. These "vanishing islands" are shrinking dramatically. Kutubdia has halved in size in 20 years, to around 100 sq km. Since 1991, six villages on the island of fishermen and saltworkers have been swamped and about 40,000 people have fled. Like Hashem, most have relocated to the coast near Cox's Bazar.

NOAA: Coastal effects of climate change threaten 50 percent of Americans

Land that roughly 50 percent of Americans call home is under threat from the coastal effects of climate change, a study published Tuesday (PDF) by the National Oceanic and Atmospheric Administration (NOAA) warns.

"An increase in the intensity of extreme weather events such as storms like Sandy and Katrina, coupled with sea-level rise and the effects of increased human development along the coasts, could affect the sustainability of many existing coastal communities and natural resources," report co-author Virginia Burkett, of the U.S. Geological Survey, said in an advisory.

The study warns that approximately 50 percent of Americans live in coastal watershed communities - a number that is projected to grow - that face increasing flood risks due to storm surges, extreme weather and rising sea levels as the climate grows more unpredictable. These risks are compounded by changes to coastal ecosystems brought about by human activity, causing "toxic algal blooms" and depleted fish stocks, loss of wetlands and dying coral reefs.

Fisheries officers have sent samples of the dead animals to a wildlife pathologist at the Atlantic Veterinary College
The Department of Fisheries and Oceans is investigating after dozens of dead seals were found on a beach and in the waters off Prince Edward Island.

A group of students from the Charlottetown-based Atlantic Veterinary College found as many as 50 dead seals over the weekend.

The students came upon the bloody carcasses of grey seals either dead or dying. Many of seals were pups.

Meric-Ipsala road in the Thrace region of Turkey has been shut down to motor vehicle traffic on Sunday due to heavy snowfall which began in Edirne province.

Aside from the Meric-Ipsala road, 37 village roads have also been shut down to traffic due to heavy snowfall in the region.

Road crews are working to open the Meric-Ipsala road to traffic again on Sunday.

Snow thickness at Uludag, one of the favorite skiing centers of Europe, reached 215 centimeters on Sunday.

The Weather Department of the north-western province of Bursa said that they expected snowfall at Uludag on both Sunday and Monday.

An underground electrical equipment fire caused a power outage in parts of downtown Omaha Sunday night. As of 10:30 a.m. Monday, OPPD reported less than 100 customers in the area were still without power.

The outage stretches from 11th Street to just west of 20th, from Leavenworth to Farnam. OPPD said it plans to have power restored by sometime Monday evening.

Due to the outage, the Douglas County Courthouse will be closed Monday. Those who are scheduled to appear in court are being sent next door to the Douglas County City building. The MUD building at 17th and Harney is closed until further notice.
