Millions of asthmatics unable to breathe as giant cloud of Saharan sand and toxic air covers Britain in layer of smog

  • Air pollution set to hit 10/10 due to dust from Sahara mixing with local pollution and toxic air from Europe
  • Parts of the South Coast, West Country, Midlands and South Wales are worst affected by the problem
  • Dust has been generated from two source areas – one in central Algeria and another in southern Morocco
  • Meteorologists say it’s ‘particularly bad with weather conditions creating “perfect storm” for air pollution’
  • Those in affected areas advised to reduce strenuous outdoor exercise, especially if they get a sore throat
  • Adults and children with lung problems, heart problems and pensioners should avoid vigorous activity
  • Asthma sufferers may have to use inhalers more frequently for a few days until levels drop on Friday
  • But the dust does have positive aspects for fish in the Atlantic Ocean and the Brazilian rainforest

Millions of asthmatics were today having trouble breathing as a potentially-lethal cloud of Saharan sand, toxic air and local pollution sat over Britain.

One sufferer said she felt like she had ‘a baby elephant sitting on my chest’, while another said her lungs felt like they had ‘cobwebs’ inside them.

Even those without health difficulties have been told by experts to reduce outdoor exercise, with air pollution set to hit 10 out of 10 in some areas.

Britons are being warned they may suffer breathing problems, with parts of the South Coast, West Country, Midlands and South Wales worst affected.

Those in affected areas are advised to reduce the strenuous outdoor exercise they do, especially if they start to suffer from a cough or sore throat.

Washington mudslide’s confirmed death toll rises to 16

The confirmed death toll for the Washington state mudslide rose to 16 on Tuesday night, and officials said rescuers might have located eight more bodies. If so, that would bring the toll to 24.

The day was rainy and difficult for the more than 200 rescue personnel scouring the mud and slurry just east of Oso, using cadaver dogs and sometimes their hands to pick through the wreckage.

“We didn’t find any signs of life; we didn’t locate anybody alive,” Travis Hots, chief of Snohomish County Fire District 21, told reporters. “Our condolences go out to the families that have lost people here.”

About 49 homes were smashed in northwestern Washington, about an hour north of Seattle, when a massive segment of land cut away from a hill along the Stillaguamish River on Saturday.

Rescuers have found no survivors since the first day, and have been holding out diminishing hope for a miracle rescue. Instead, the death toll has continued to rise, with two more bodies recovered Tuesday, Hots said.

Hope for survivors of landslide dims as death toll rises as high as 24

After landslide, search for missing ahead

STORY HIGHLIGHTS
  • NEW: Two more bodies have been recovered and up to eight more have been located
  • NEW: Lists of missing and unaccounted for are being revised, an official says
  • The body of a Navy commander and his dog have been recovered, the family says
  • Landslide has affected or destroyed nearly 50 structures, officials say

Darrington, Washington (CNN) — Brenda Neal was still at the firehouse at midnight, watching as rescuers caked with mud returned from the search for survivors of a massive landslide in rural Washington state.

But they had no answers for her about her missing husband, Steven.

There was despair on their faces, she said.

Rescuer: Houses exploded from the mud

Rescuers on Tuesday continued to battle debris and mud — with the consistency of quicksand in some places — in the search for survivors, but hopes dimmed as news broke that more bodies were found.

“Unfortunately, we didn’t find any signs of life,” Snohomish County Fire District 21 Chief Travis Hots told reporters during a briefing.

The number of dead climbed to as high as 24 with the recovery Tuesday of two more bodies and another eight believed to have been located in the debris.

Authorities did not immediately release the identities of the dead nor did they provide details about where the bodies were found.

At least 176 people are unaccounted for. Officials have stressed those unaccounted for are not necessarily all victims of the disaster. They say they believe many names have been duplicated.

Three sheriff’s deputies who specialize in missing persons cases have begun reviewing the lists to get a more accurate count,Snohomish County Emergency Management Director John Pennington said.

Steven Neal’s family holds out hope, despite discouraging signs.

Neal is a plumber who was on a service call in the area where the landslide hit.

“None of us feel like he’s gone,” Brenda Neal said.

Her daughter, Sara, agreed: “I think if anyone had a chance to getting through, it would be him.”

The waiting came to end Tuesday for the family of U.S. Navy Cmdr. John Regelbrugge, 49, whose body and that of his dog were found by his brothers, his sister-in-law, Jackie Leighton, told CNN. Still missing is Regelbrugge’s wife, she said.

On Monday, search efforts yielded a grim result — six bodies.

But searchers still are going through the area with the hopes of making rescues, Pennington said earlier Tuesday morning.

“I believe in miracles, and I believe people can survive these events. They’ve done it before,” and they can do it again, he told reporters.

The landslide covered about a square mile and was caused by groundwater saturation tied to heavy rain in the area over the past month. It affected Oso, with a population of about 180, and Darrington, a town of about 1,350.

Authorities have been warning the search area remains unstable

A volunteer rescue worker was injured Tuesday while working in an area where the landslide struck, according to a statement released by the Snohomish County Sheriff’s Office. The rescue worker was hit in the head by debris kicked up “in helicopter wash,” it said.

President Barack Obama, in the Netherlands on Tuesday, asked that “all Americans to send their thoughts and prayers to Washington state and the community of Oso.”

Obama said he had spoken with Gov. Jay Inslee and signed an emergency declaration.

Early hopeful signs, such as the rescue of a 4-year-old boy on the day of the landslide, have faded for some.

Vibrating Gwinnett Co. homes mystify neighbors

11:06 PM, Feb 27, 2014

GWINNETT COUNTY, Ga. — It is a steady staccato beat, unerring and continuous. Just low enough in frequency to be annoying, yet strong enough to literally shake a house.

Several in fact.

Nerves too have been shaken in this community along Little Mill Road in Gwinnett County, when neighbors awoke to the strange vibrations.

“This is my wine cooler,” said resident Gayle Akana, demonstrating the way the appliance vibrates. “And if you (touch it), it stops. And that’s what happened with the vibration when we like pressed against the wall or bed.”

Akana says her house shook for six hours.

“It was just shaking like crazy,” Akana said. “It was real quick; I can’t even replicate the sound it was making. It was just a constant shaking.”

At first she thought there was a problem with the pump or pipes in her backyard pond. But a quick check there showed nothing but sleeping koi. That’s when she went to the computer and noticed that Facebook started blowing up with other neighbors reporting the same mysterious phenomenon.

Description
Sunbathers, swimmers and casual visitors at the world’s longest beach, the Praia do Cassino (literally Casino Beach) in Rio Grande, Brazil, were captured by surprise this past Sunday when a bizarre natural phenomenon known as a Meteorological Tsunami, Meteotsunami or simply, weather-induced tsunami, hit the area. It caused the sea to swell and spill out a wave that reached all the way up to the parking spots (…or at least where people had parked their rides, possibly too close to the beach), and while humans escaped unscathed, their belongings, including dozens of vehicles, were damaged, as the body of water tossed the cars around on the sand. According to locals, this isn’t the first time that such a tsunami has been observed in the area. Meteorological tsunami (meteotsunami) “Tsunami-like phenomena generated by meteorological or atmospheric disturbances. These waves can be produced by atmospheric gravity waves, pressure jumps, frontal passages, squalls, gales, typhoons, hurricanes and other atmospheric sources.” “Meteotsunamis have the same temporal and spatial scales as tsunami waves and can similarly devastate coastal areas, especially in bays and inlets with strong ampli?cation and well-de?ned resonant properties.”

The powerful earthquake that hit Pakistan on Tuesday (Sept. 24) and killed more than 320 people struck along one of the most hazardous yet poorly studied tectonic plate boundaries in the world.

The magnitude-7.7 earthquake was likely centered on a southern strand of the Chaman Fault, said Shuhab Khan, a geoscientist at the University of Houston. In 1935, an earthquake on the northern Chaman Fault killed more than 30,000 people and destroyed the town of Quetta. It was one of the deadliest quakes ever in Southeast Asia.

Shaking from yesterday’s earthquake in Pakistan demolished homes in the Awaran district near the epicenter, according to news reports. The death toll will likely rise as survivors and emergency workers search the debris.

In the hours after the quake, a new island suddenly rose offshore in shallow seas near the town of Gwadar, about 230 miles (380 kilometers) southwest of the epicenter. Geologists with the Pakistan Navy have collected samples from the rocky pile, the Associated Press reported. From pictures and descriptions, many scientists think the mound is a mud volcano, which often erupt after strong earthquakes near the Arabian Sea. A second island has also been reported offshore of Ormara, about 170 miles (280 km) east of Gwadar, Geo News said.

“Other mud volcanoes have been triggered at this distance for similar size earthquakes,” Michael Manga, a geophysicist and expert on mud volcanoes at the University of California, Berkeley, told LiveScience’s OurAmazingPlanet.

Little known risk

The unexplained island may have focused unusual global attention on the earthquake, which hit in a region that frequently experiences devastating temblors. [Video: Island Appears After Pakistan Earthquake]

But despite the hazards faced by millions living near the Chaman Fault, a combination of geography and politics means the seismic zone remains little studied. The Taliban killed 10 climbers, including an American,  in northern Pakistan in June.

“Its location is in an area that is very difficult to do any traditional field work,” Khan told LiveScience’s OurAmazingPlanet. “I tried twice to submit proposals to [the National Science Foundation] and I got excellent reviews, but the review panel said I was risking my life to work in that area.”

But the National Academy of Sciences felt differently. With their support, Khan and his colleagues in Pakistan and at the University of Cincinnati are now studying the fault’s current and past movement. This will help the researchers forecast future earthquake risk.

“This fault has had very little work and no paleoseismology,” Khan said. “It is really important.”

Complex collision zone

Pakistan’s deadly earthquakes owe their birth to the juncture of three colliding tectonic plates: Indian, Eurasian and Arabian. The Indian and Eurasian plates grind past each other along the Chaman Fault, triggering destructive temblors.

Published September 25, 2013

On Tuesday, a 7.7-magnitude earthquake struck a remote part of western Pakistan, killing more than 260 people and displacing hundreds of thousands. It also triggered formation of a new island off the coast, which has quickly become a global curiosity.

But scientists say the island won’t last long.

“It’s a transient feature,” said Bill Barnhart, a research geophysicist with the U.S. Geological Survey. “It will probably be gone within a couple of months. It’s just a big pile of mud that was on the seafloor that got pushed up.”

Indeed, such islands are formed by so-called mud volcanoes, which occur around the world, and Barnhart and other scientists suspect that’s what we’re seeing off the Pakistani coast.

News organizations have reported that the Pakistani island suddenly appeared near the port of Gwadar after the quake. The island is about 60 to 70 feet (18 to 21 meters) high, up to 300 feet (91 meters) wide, and up to 120 feet (37 meters) long, reports the AFP.

Media reports have located the new island at just a few paces to up to two kilometers off the coast of Pakistan. It is about 250 miles (400 kilometers) from the epicenter of the earthquake.

The island appears to be primarily made out of mud from the seafloor, although photos show rocks as well, Barnhart told National Geographic. He has has been studying images and media accounts of the new island from his lab in Golden, Colorado.

“It brought up a dead octopus, and people have been picking up fish on [the island],” he said.

Stumps have been thawing from beneath the Mendenhall Glacier for about 50 years, but recently, considerably more have been found in upright positions with roots still intact.

An ancient forest has thawed from under a melting glacier in Alaska and is now exposed to the world for the first time in more than 1,000 years.

Stumps and logs have been popping out from under southern Alaska’s Mendenhall Glacier — a 36.8-square-mile (95.3 square kilometers) river of ice flowing into a lake near Juneau — for nearly the past 50 years. However, just within the past year or so, researchers based at the University of Alaska Southeast in Juneau have noticed considerably more trees popping up, many in their original upright position and some still bearing roots and even a bit of bark, the Juneau Empire first reported last week.

“There are a lot of them, and being in a growth position is exciting because we can see the outermost part of the tree and count back to see how old the tree was,” Cathy Connor, a geology professor at the University of Alaska Southeast who was involved in the investigation, told LiveScience’s OurAmazingPlanet. “Mostly, people find chunks of wood helter-skelter, but to see these intact upright is kind of cool.”

The team has tentatively identified the trees as either spruce or hemlock, based on the diameter of the trunks and because these are the types of trees growing in the region today, Connor said, but the researchers still need to further assess the samples to verify the tree type.

A protective tomb of gravel likely encased the trees more than 1,000 years ago, when the glacier was advancing, Connor said, basing the date on radiocarbon ages of the newly revealed wood. As glaciers advance, Connor explained, they often emit summer meltwater streams that spew aprons of gravel beyond the glacier’s edge. [Images: Shrinking Alaska Glacier Spied from Space]

A gravel layer about 4 to 5 feet (1.2 to 1.5 meters) high appears to have encased the trees before the glacier ultimately advanced enough to plow over them, snapping off limbs and preserving the stumps in an ice tomb.

10.07.2013 Climate Change Antarctica [Pine Island Glacier] Damage level
Details

….

Climate Change in Antarctica on Wednesday, 10 July, 2013 at 10:15 (10:15 AM) UTC.

 

Description
Pine Island Glacier (PIG), the longest and fastest flowing glacier in the Antarctic, has spawned a huge iceberg. The block measures about 720 sq km in area – roughly eight times the size of Manhattan Island in New York. Scientists have been waiting for the PIG to calve since October 2011 when they first noticed a spectacular crack spreading across its surface. Confirmation that the fissure had extended the full width of the glacier was obtained on Monday. It was seen by the German TerraSAR-X satellite. This carries a radar instrument that can detect the surface of the ice stream even though the Antarctic is currently in the grip of winter darkness. The berg that broke away was part of the PIG’s ice shelf – the front segment of the glacier that lifts up and floats as it pushes out into the ocean. The shelf will reach tens of km beyond the grounding line. German researchers have been receiving images from TerraSAR-X every three days or so, hoping to understand better the processes that drive the glacier forward and prompt it to fracture. This will help them improve the computer models that are used to forecast future changes in the Antarctic. “We were very keen to see how the crack propagated,” said Prof Angelika Humbert, a glaciologist with the Alfred Wegener Institute. “We need proper calving laws, to be able to describe the evolution of ice sheets over centuries,” she told BBC News.

Very big tabular bergs will come off the end of the ice shelf every 6-10 years. Previous notable events occurred in 2007 and 2001. It is a very natural process and scientists say it should not be tied directly to the very real climate changes that are also affecting this part of the West Antarctic Ice Sheet. Satellite and airborne measurements have recorded a marked thinning and a surge in velocity of the PIG in recent decades. This has been attributed in part to warmer waters getting under, and melting, the ice shelf. The PIG’s grounding line has pulled back further and further towards the land. The glacier’s behaviour means it is now under close scrutiny, not least because it drains something like 10% of all the ice flowing off the west of the continent. “The PIG is the most rapidly shrinking glacier on the planet,” explained Prof David Vaughan from the British Antarctic Survey (BAS). “It’s losing more ice than any other glacier on the planet, and it’s contributing to sea level rise faster than any other glacier on the planet. That makes it worthy of study.” BAS has recently deployed a series of instrumented “javelins” along the PIG to monitor its movement. When the big crack propagating across the 30km width of the PIG was first photographed in 2011 by a Nasa airborne expedition, many assumed the moment of final calving would come quite quickly.

That it took almost two years for the tabular berg to break away is something of a surprise, concedes Prof Humbert. What should not be a surprise, she says, is that it has occurred in deep winter when the ocean is covered in sea-ice. This relatively thin covering would always be overwhelmed by the internal stresses in the massive ice shelf. What will be interesting now, she adds, is to see how long it takes for the berg to move out of the bay in front of it. It could take several months. TerraSAR-X will provide the tell-tale data. The world’s largest recorded iceberg was the tabular block that became known as B-15. When it broke off the Ross Ice Shelf in 2001, it had a surface area of about 11,000 sq km. It took years to melt away as it moved out into the Southern Ocean.

Published February 2, 2012

 

With a gargantuan crack slowly splitting it apart, Antarctica‘s fastest-melting glacier is about to lose a chunk of ice larger than all of New York City, scientists say.

(Also see “Manhattan-Size Ice Island Cracks in Half.”)

The crevasse stretches 19 miles (30 kilometers) long and up to 260 feet (80 meters) wide, as shown in a picture taken by NASA’s Terra satellite in October and featured this week as a NASA Image of the Day.

Snaking across the floating tongue of the Pine Island Glacier in West Antarctica, the crack is expected to create an iceberg 350 square miles (907 square kilometers)—versus 303 square miles (785 square kilometers) for Manhattan, Brooklyn, Queens, Staten Island, and the Bronx combined, according to NASA.

As for when the iceberg might shove off, “that is very difficult to predict,” said oceanographer Eric Rignot of NASA’s Jet Propulsion Laboratory, “but in the coming months for sure.”

Glacier “Contributing Most to Sea Level”

Usually there’s nothing extraordinary about a glacier calving, said glaciologist Ted Scambos of the National Snow and Ice Data Center (NSIDC) in Boulder, Colorado.

Glaciers that flow into the sea, like the Pine Island Glacier, go through a normal cycle in which the floating section grows, stresses mount, and an iceberg breaks off, Scambos said.

“That is nothing unusual in most cases.”

Giant Wave Impact in Chile on Friday, 05 July, 2013 at 07:35 (07:35 AM) UTC.

Description
Waves as high as seven metres pounded homes and businesses on Chile’s coastline. The extreme conditions started on Wednesday with weather experts warning they could last until the weekend. High winds caused the tidal surges which have led emergency services to issue weather warnings to 11 regions in the South American country predicting strong winds, high tides and large waves. In the city of Vina del Mar about 120 kilometres west of the capital Santiago the waves washed over sea defences flooding coastal streets and damaging homes and businesses. Seaside resorts also suffered and one port was forced to close to all vessels. In another area eight homes were flooded and 32 people affected.

….

Huge waves hit Chile and Peru

Waves as high as 7m (22 ft) have hit parts of Chile and coastal areas are on alert as high winds and tidal currents sweep across parts of South America’s coast.

Footage showed huge waves surging onto the streets of Antofagasta in Chile where at least one injury was reported following the dangerous weather.

In Peru, parts of the country’s coastline were hit with waves as big as 5m (16 ft) and the weather caused flooded streets in the seaside city of Chimbote.

Lower pollution levels linked to worse hurricanes

Scientists from Britain’s Meteorological Office have fingered a new suspect in their attempt to solve the mystery of tropical storms. It is, unexpectedly, air quality.

If North Atlantic hurricanes are more destructive or more frequent, it may be linked to lower levels of atmospheric pollution. Conversely, sulphate aerosols and other particles from factory chimneys, vehicle exhausts, domestic fires, power stations and other human economic advances may have played a role in keeping tropical storms under control, at least a little, during the 20th century.

Climate scientist Nick Dunstone and fellow-researchers at the Met Office’s Hadley Centre in Exeter, Devon, report in the Nature Geoscience journal there is at least circumstantial evidence that aerosols play a more significant role in the storm cycle than anyone had expected.

The reason it has been difficult to separate the effect is a simple one: when humans burn fossil fuels, they release greenhouse gases that slowly but inexorably warm the atmosphere, and therefore the oceans. Atmosphere and ocean are together a climate system: put more energy in, and it must go somewhere. The likely consequences, most people have thought, are extremes of wind and rain.

However, for most of the 20th century, humans released greenhouse gases and also all sorts of other waste at the same time: specifically, sulphate aerosols that, as urban smog, darkened buildings, increased the acidity of the falling rain, rotted limestone structures and condemned hundreds of thousands to bronchial illnesses and, ultimately, to early graves.

It didn’t seem possible to separate the effects – at least, not until Britain, western European nations and North America introduced increasingly strict clean air legislation.

This started to give scientists and climate modellers a chance to tease out the different effects of the two pollutants. Aerosols are important absorbers of sunlight, and they are also important in cloud chemistry – water vapour droplets have to condense on something. But important in what way? Do clouds reflect sunlight and cool the region? Or do they build up prodigious quantities of moving water and turn into the frenzies of a tropical storm? Or, overall, do sulphates cool the atmosphere a little and counteract global warming − and, if so, under what conditions?
