Green tea and mushrooms

Sounds like the start of a joke.... but apparently it helps in fending off breast cancer.

And deep space is messy:

ScienceDaily (Mar. 17, 2009) — A new image from NASA's Spitzer Space Telescope offers a rare view of an imminent collision between the cores of two merging galaxies, each powered by a black hole with millions of times the mass of the sun.

The galactic cores are in a single, tangled galaxy called NGC 6240, located 400-million light years away in the constellation Ophiuchus. Millions of years ago, each core was the dense center of its own galaxy before the two galaxies collided and ripped each other apart. Now, these cores are approaching each other at tremendous speeds and preparing for the final cataclysmic collision. They will crash into each other in a few million years, a relatively short period on a galactic timescale.

What big teeth you have, Grandma:

A marine monster described as the most fearsome animal ever to swim in the oceans boasted a bite up to 11 times as strong as that of Tyrannosaurus rex.

The fossil remains of the huge pliosaur were dug up last summer from the permafrost on Svalbard, a Norwegian island close to the North Pole.

Analysis revealed that it was a turbo-charged swimmer. Its front flippers allowed the creature, dubbed Predator X, to cruise along comfortably but when prey came into range the power of its hind flippers kicked in to provide extra acceleration.

Measurements of its jaw and the killing power of its dagger-like teeth have shown that it could bite down with a force of 33,000lb per square inch compared with T. rex’s 3,000lb per square inch. Alligators have the strongest bite today with about 2,500lb per square inch.

And I doubt we're talking about crunching on coconuts, either.

Just a word of advice...

Don't buy a house near the beach. Buy the one on the hill, it will be beachfront property in a few years...

California's interagency Climate Action Team on Wednesday issued the first of 40 reports on impacts and adaptation, outlining what the state's residents must do to deal with the floods, erosion and other effects expected from rising sea levels.

Hundreds of thousands of people and billions of dollars of Golden State infrastructure and property would be at risk if ocean levels rose 55 inches by the end of the century, as computer models suggest, according to the report.

The group floated several radical proposals: limit coastal development in areas at risk from sea rise; consider phased abandonment of certain areas; halt federally subsidized insurance for property likely to be inundated; and require coastal structures to be built to adapt to climate change.

"Immediate action is needed," said Linda Adams, secretary for environmental protection. "It will cost significantly less to combat climate change than it will to maintain a business-as-usual approach."

Because the Arctic ice cap is melting:

(CNN) -- It could be the ultimate test of human endurance: Three British explorers are risking their lives in subzero temperatures to measure the melting Arctic ice cap.

The team is on a three-month, 621-mile (1,000-kilometer) hike to their final destination at the North Pole. Along the way, taking precise measurements to determine exactly how fast the ice cap is disappearing.

[snip]

The unique expedition was prompted by this chilling prospect: The Arctic ice cap is melting at an unprecedented rate, which may lead to a dramatic shift in average global temperatures.

"In 2007, sea ice loss was the worst in recorded history," said oceanographer Kate Moran, professor of oceanography and ocean engineering at the University of Rhode Island.

The last time that scientists can say confidently that the Arctic was free of summertime ice was 125,000 years ago, according to the Web site of the National Snow and Ice Data Center in Boulder, Colorado.

All that could vanish within our lifetime, warn climate scientists, who predict that the Arctic sea ice in the summer season could be gone between 2013 and 2040.

Include Greenland and the Antarctic in that:

Scientists will warn this week that rising sea levels, triggered by global warming, pose a far greater danger to the planet than previously estimated. There is now a major risk that many coastal areas around the world will be inundated by the end of the century because Antarctic and Greenland ice sheets are melting faster than previously estimated.

Low-lying areas including Bangladesh, Florida, the Maldives and the Netherlands face catastrophic flooding, while in the UK, the Thames estuary is likely to disappear by 2100. Cities like London will need new flood defenses.

“It is now clear that there are going to be massive flooding disasters around the globe,” said David Vaughan of the British Antarctic Survey. “Populations are shifting to the coast, which means that more and more people are going to be threatened by sea-level rises.”

And um... bulges of water roaring about the globe?

Scientists say the collapse of the West Antarctic Ice Sheet would have such profound effects it would shift the planet's rotation, sending a bulge of water into the Northern Hemisphere.

The enormous ice sheet, which many experts believe could collapse as the climate warms, is so heavy that as it melts it "will actually cause the Earth's rotation axis to shift rather dramatically," reports a team led by geophysicist Jerry Mitrovica, at the University of Toronto. The scientists say the North and South poles would move about half a kilometre if the entire ice sheet collapses and shifts more water north.

Coastal regions from Washington to Vancouver could expect sea levels to rise at least six metres, Mitrovica and his colleagues report Friday in the journal Science. Much of Florida would be drowned as would low-lying areas in Maritime Canada, the Arctic and along the Pacific coast.

There is nowhere on the coast of Canada or the U.S. that the sea level won't rise to at least six metres, Mitrovica said in an interview.

He and his colleagues stress that the collapse of the West Antarctic Ice Sheet, while a big concern, is not imminent and may not occur for centuries. "But these findings do suggest that if you are planning for sea level rise, you had better plan a little higher," says co-author Peter Clark at Oregon State University.

The United Nations Intergovernmental Panel on Climate Change has estimated that a collapse of the ice sheet would raise global sea levels by about five metres - a figure that has led to the "simplistic" idea that water will rise evenly around the planet, says Mitrovica.

For those who mock global warming

By pointing to the US's severe winter storm, here's what's happening in Australia:

South-eastern Australia is experiencing its worst heatwave in decades, with temperatures in excess of 43C (109F).

Health officials in South Australia say the searing heat may be to blame for an apparent increase in the number of sudden deaths among the elderly.

In neighbouring Victoria state, bush fires have destroyed at least 10 homes.

Nearly 500,000 people in the state are reported to have lost their power supplies, following severe pressure on the electricity grid.

An explosion was also reported at a substation in Melbourne, Australia's second-largest city.

"It is an extreme week. The system is not made to operate where you've got temperatures in the suburbs of 46C," said the head of Victoria state, John Brumby.

Commuters are facing long delays after the blackouts added to the problems on the rail network. Hundreds of train services were cancelled after the heat buckled tracks.

The phrase global warming is unfortunate as it should really be called climate change. The weather will become more extreme at both ends of the gauge, extreme heat, extreme cold. There will be more droughts, floods, fires. Meanwhile, glaciers are losing their ice and the poles are melting, the oceans are acidifying, creatures are going extinct.





Even if we negated our carbon footprints right now, this shift in climate will still continue for decades. We can thank the Bush administration for eight more years of delay in addressing this.

George Bush surprised world leaders with a joke about his poor record on the environment as he left the G8 summit in Japan.

The American leader, who has been condemned throughout his presidency for failing to tackle climate change, ended a private meeting with the words: "Goodbye from the world's biggest polluter."

He then punched the air while grinning widely, as the rest of those present including Gordon Brown and Nicolas Sarkozy looked on in shock.

Mr Bush, whose second and final term as President ends at the end of the year, then left the meeting at the Windsor Hotel in Hokkaido where the leaders of the world's richest nations had been discussing new targets to cut carbon emissions.

One official who witnessed the extraordinary scene said afterwards: "Everyone was very surprised that he was making a joke about America's record on pollution."

But maybe we can hope:

DAVOS, Switzerland (AP) — Nobel Peace Prize winner Al Gore urged President Barack Obama and other world leaders to seal a quick deal to fight global warming despite the pervasive financial crisis.

Gore called Obama "the greenest person in the room" for making environmental funding a big chunk of the $819 billion economic stimulus bill passed by U.S. lawmakers this week.

"I think it's important for the world leaders gathered here to fully appreciate the magnitude of the change in U.S. leadership," Gore said.

The former U.S. vice president and environmental advocate, speaking at the World Economic Forum in Davos, referred to frustration in many countries at the Bush administration's refusal to sign international pacts on reducing emissions of carbon, blamed for global warming.

If you're happy and you know it...

We haven't found out what's killing our honey bees yet:

WASHINGTON - Food prices could rise even more unless the mysterious decline in honey bees is solved, farmers and businessmen told lawmakers Thursday.

[snip]

About three-quarters of flowering plants rely on birds, bees and other pollinators to help them reproduce. Bee pollination is responsible for $15 billion annually in crop value.

In 2006, beekeepers began reporting losing 30 percent to 90 percent of their hives. This phenomenon has become known as Colony Collapse Disorder. Scientists do not know how many bees have died; beekeepers have lost 36 percent of their managed colonies this year. It was 31 percent for 2007, said Edward B. Knipling, administrator of the Agriculture Department's Agricultural Research Service.

"If there are no bees, there is no way for our nation's farmers to continue to grow the high quality, nutritious foods our country relies on," said Democratic Rep. Dennis Cardoza of California, chairman of the horticulture and organic agriculture panel. "This is a crisis we cannot afford to ignore."

Food prices have gone up 83 percent in three years, according to the World Bank.

We're turning our oceans into an acid bath:

FORT LAUDERDALE, Florida (Reuters) - Like a tooth dipped in a glass of Coca-Cola, coral reefs, lobsters and other marine creatures that build calcified shells around themselves could soon dissolve as climate change turns the oceans increasingly acidic.

The carbon dioxide spewed into the atmosphere by factories, cars and power plants is not just raising temperatures. It is also causing what scientists call "ocean acidification" as around 25 percent of the excess CO2 is absorbed by the seas.

The threat to hard-bodied marine organisms, such as coral reefs already struggling with warming waters, is alarming, and possibly quite imminent, marine scientists gathered this week for a coral reef conference in Fort Lauderdale, Florida, said.

We are running out of rain forests, wood, and land to grow crops:

Demand for land to grow food, fuel crops and wood is set to outstrip supply, leading to the probable destruction of forests, a report warns.

The Rights and Resources Initiative (RRI) says only half of the extra land needed by 2030 is available without eating into tropical forested areas.

We're losing the penquins:

RIO DE JANEIRO, Brazil - Hundreds of baby penguins swept from the icy shores of Antarctica and Patagonia are washing up dead on Rio de Janeiro's tropical beaches, rescuers and penguin experts said Friday.

And what we're not losing is being made toxic:

The Maine Center for Disease Control said Friday that lobster meat is perfectly safe but that people should not eat the tomalley — a soft green substance found in the body of the lobster.

High levels of toxic algae known as red tide have been recorded along Maine's coast this summer, forcing the state to close many areas to clam and mussel harvesting. Tomalley functions as the lobster's liver by serving as a natural filter for contaminants that are in the water.

And:

WASHINGTON - The tomato scare may be over, but it has taken a toll — it's cost the industry an estimated $100 million and left millions of people with a new wariness about the safety of everyday foods.

I'm reading Jared Diamond's Collapse which talks about societies which become unsustainable yet the people continue to misuse and use up their resources. Overpopulation is one factor. Inability to anticipate and plan for future disasters is another. What is happening now has been repeated several times before.

I just never expected to actually be here when everything broke all at once.

And so the fun begins

Birds not migrating:

But in a sign of the blurring of the seasons brought on by climate change, one of the birds has this year shunned migration to Africa and instead spent all winter in Britain.

In what experts say is the first documented evidence of the species "overwintering" here, a solitary swallow has been monitored from November to the end of February in a village near Truro, Cornwall.

Paul Stancliffe, a spokesman for the British Trust for Ornithology (BTO), called the discovery "incredible".

[snip]

In the BTO programme, a single wheatear was found to have overwintered in Burniston, near Scarborough, North Yorkshire, instead of in west Africa. Some 5,000 chiffchaffs, which normally migrate there or to Spain or Morocco, spent the winter in Britain. Mr Stancliffe said: "These are birds that would ordinarily migrate south of the Sahara. We believe it is because our winters are getting milder and birds are actually able to survive here through the winter."

The bird atlas programme will run until 2011, with 50,000 volunteers reporting sightings. The last time the exercise was carried out, in the 1980s, fewer than 1,000 chiffchaffs were found to be overwintering in Britain.

As further evidence of climate change, volunteers have also recorded "early returns" by many migrants this year, as well as unseasonably early nesting by birds that ordinarily remain here.

Salmon are dying via Kirk Murphy at Firedoglake:

The largest salmon run in the largest estuary on this hemisphere's Pacific Coast has collapsed. Why care about a bunch of fish and a big marsh? Well, healthy salmon runs require healthy water: fresh and salt. Crashing salmon runs tell us something in the water(s) has gone terrribly wrong. SF Bay fresh water is sucked up to supply central California crops and communities and Southern California taps. With over 17 million people in the LA area alone, and with California producing over half the nation's fruit, vegetables, and nuts, SF Bay water affects the price of your greens - and the health of your family, wherever they live. And the salmon tell us the Bay is very sick.

Polar ice is melting faster than expected (via Sorghum Crow):

WASHINGTON (Reuters) - The thickest, oldest and toughest sea ice around the North Pole is melting, a bad sign for the future of the Arctic ice cap, NASA satellite data showed on Tuesday.

But wait! We're saved! They've invented this:



Oddly it reminds me of the Mechanical Hound in Fahrenheit 451 .... which is why I want to beat it to death immediately.

It's actually an SOS signal

Prepare for the alien invasion!:

Hampton, VA (AHN) - Initial results of a National Aeronautics and Space Administration (NASA) satellite study of the polar night clouds indicate that the phenomenon is getting brighter and expanding, so that its visibility now reach farther from the poles.

Jim Russell, Hampton University's atmospheric science professor and lead researcher of the Aeronomy of Ice in the Mesosphere (AIM) satellite project, theorizes that global warming is causing the changes in night clouds. AIM is the first satellite to study the night clouds.

If I'm not underwater...

Thailand(AP)-- Cities around the world are facing the danger of rising seas and other disasters related to climate change.

Of the 33 cities predicted to have at least 8 million people by 2015, at least 21 are highly vulnerable, says the Worldwatch Institute.

They include Dhaka in Bangladesh; Buenos Aires, Rio de Janeiro; Shanghai and Tianjin in China; Alexandria and Cairo in Egypt; Mumbai and Kolkata in India; Jakarta in Indonesia; Tokyo and Osaka-Kobe in Japan; Lagos in Nigeria; Karachi in Pakistan; Bangkok in Thailand, and New York and Los Angeles in the United States, according to studies by the United Nations and others.

More than one-tenth of the world's population, or 643 million people, live in low-lying areas at risk from climate change, say U.S.and European experts. Most imperiled, in descending order, are China, India, Bangladesh, Vietnam, Indonesia, Japan, Egypt, U.S., Thailand, and the Philippines.

And speaking of new waterways:

WASHINGTON, Oct. 18 — For most of human history, the Arctic Ocean has been an ice-locked frontier. But now, in one of the most concrete signs of the effect of a warming climate on government operations, the Coast Guard is planning its first operating base there as a way of dealing with the cruise ships and the tankers that are already beginning to ply Arctic waters.
With increasingly long seasons of open water in the region, the Coast Guard has also begun discussions with the Russians about controlling anticipated ship traffic through the Bering Strait, which until now has been crossed mainly by ice-breaking research vessels and native seal and walrus hunters.
The Coast Guard says its base, which would probably be near the United States’ northernmost town, Barrow, Alaska, on the North Slope coast, would be seasonal and would initially have just a helicopter equipped for cold-weather operations and several small boats.
But given continued warming, that small base, which could be in place by next spring, would be expanded later to help speed responses to oil spills from tankers that the Coast Guard believes could eventually carry shipments from Scandinavia to Asia through the Bering Strait. Such a long-hoped-for polar route would cut 5,000 miles or more from a journey that would otherwise entail passage through the Panama Canal or the Suez.

About that global warming thing....

Copenhagen - Danish researchers have provided further evidence to suggest how the North Pole's ice cap is shrinking, reports said Monday. "The ice cap is at an extreme low. For the 50 years we have data from, we have never seen anything like it," Leif Toudal Pedersen of the Technical University of Denmark told the Jyllands-Posten newspaper.

A survey based on satellite imagery from Sunday suggested that the ice cap was 40 to 45 per cent less - or a reduction of 2.5 million square kilometres - than on average during the period 1997-2000, the newspaper reported.

[snip]

Global warming was a contributing factor, but this year strong currents have also swept large masses of ice from Siberia via the North Pole past eastern Greenland and further south where it melted, Pedersen said.

Ice free summers in the North Pole area could be a reality in 15 to 20 years as opposed to previous projections of 30 to 40 years, he said.

No matter what the White House says about it, it is happening.

Screw the polar bears!

Think of all the oil we can get to now!: (FYI: for those who are reading only this post, this is sarcasm.)

Arctic sea ice is expected to retreat to a record low by the end of this summer, scientists have predicted.

Measurements made by the US National Snow and Ice Data Center (NSIDC) showed the extent of sea ice on 8 August was almost 30% below the long-term average.

Because the region's melting season runs until the middle of September, scientists believe this summer will end with the lowest ice cover on record.

Researchers have forecast ice-free summers in the Arctic by 2040.

NSIDC data showed sea ice extent for 8 August as 5.8 million sq km (2.2 million sq miles), compared to the 1979-2000 August average of 7.7 million sq km (3.0 million sq miles).

The current record low was recorded in 2005, when Arctic sea ice covered just 5.32 million sq km (2.09 million sq miles).

[snip]

A team of scientists from the National Center for Atmospheric Research (NCAR), the University of Washington, and McGill University, found that "positive feedbacks" were likely to accelerate the decline of the region's ice system.

Sea ice has a bright surface that reflects 80% of the sunlight that strikes it back into space. However, as the ice melts during the summer, more of the dark ocean surface becomes exposed.

Rather than reflecting sunlight, the ocean absorbs 90% of it, causing the waters to warm and increase the rate of melting.

Scientists fear that this feedback mechanism will have major consequences for wildlife in the region, not least polar bears, which traverse ice-floes in search of food.

On a global scale, the Earth would lose a major reflective surface and so absorb more solar energy, potentially accelerating climatic change across the world.

Russia claims North Pole for oil exploration

Santa is pissed:

V MOSCOW — An expedition aimed at strengthening Russia's claim to much of oil and gas wealth beneath the Arctic Ocean reached the North Pole on Wednesday, and preparations immediately began for two mini-submarines to drop a capsule containing a Russian flag to the sea floor.

The Rossiya icebreaker had plowed a path to the pole through an unbroken sheet of multiyear ice, clearing the way for the Akademik Fedorov research ship to follow, said Sergei Balyasnikov, a spokesman for the Arctic and Antarctic research institute that prepared the expedition.

"For the first time in history people will go down to the sea bed under the North Pole," Balyasnikov told The Associated Press. "It's like putting flag on the moon."
