Hurricane Sandy was the largest storm to hit the northeast U.S. in recorded history, killing 159, knocking out power to millions, and causing $70 billion in damage in eight states. Sandy also put the vulnerability of critical infrastructure in stark relief by paralyzing subways, trains, road and air traffic, flooding hospitals, crippling electrical substations, and shutting down power and water to tens of millions of people. But one of the larger infrastructure failures is less appreciated: sewage overflow.

Six months after Sandy, data from the eight hardest hit states shows that 11 billion gallons of untreated and partially treated sewage flowed into rivers, bays, canals, and in some cases, city streets, largely as a result of record storm-surge flooding that swamped the region’s major sewage treatment facilities. To put that in perspective, 11 billion gallons is equal to New York’s Central Park stacked 41 feet high with sewage, or more than 50 times the BP Deepwater Horizon oil spill. The vast majority of that sewage flowed into the waters of New York City and northern New Jersey in the days and weeks during and after the storm.

Scientists think that they have the answer to why the skin on human fingers and toes shrivels up like an old prune when we soak in the bath. Laboratory tests confirmed a theory that wrinkly fingers improve our grip on wet or submerged objects, working to channel away the water like the rain treads in car tyres. […]

Wrinkled fingers could have helped our ancestors to gather food from wet vegetation or streams, Smulders adds. The analogous effect in the toes could help us to get a better footing in the rain.

A thousand years ago, the Doge Pietro Orseolo II took his triumphant naval fleet to the sea entrance at the Lido and ceremoniously threw a diamond ring into the water, thus marrying his city to the Adriatic and securing Venice’s dominion over its waters and trade routes. […]

When Goethe visited Venice for just over two weeks in 1786, he climbed the campanile twice, at high tide and then at low tide. It was from this tower that, at the age of 37 and already famous, he saw the sea for the first time in his life. […]

Now we know for sure that the ocean is rising faster than Venice will subside.

Once in our history, the world-wide population of human beings skidded so sharply we were down to roughly a thousand reproductive adults. One study says we hit as low as 40. […] around 70,000 B.C., a volcano called Toba, on Sumatra, in Indonesia went off, blowing roughly 650 miles of vaporized rock into the air. It is the largest volcanic eruption we know of, dwarfing everything else… […] With so much ash, dust and vapor in the air, Sam Kean says it’s a safe guess that Toba “dimmed the sun for six years, disrupted seasonal rains, choked off streams and scattered whole cubic miles of hot ash (imagine wading through a giant ashtray) across acres and acres of plants.” Berries, fruits, trees, African game became scarce; early humans, living in East Africa just across the Indian Ocean from Mount Toba, probably starved, or at least, he says, “It’s not hard to imagine the population plummeting.”

Then — and this is more a conjectural, based on arguable evidence — an already cool Earth got colder. The world was having an ice age 70,000 years ago, and all that dust hanging in the atmosphere may have bounced warming sunshine back into space. So we almost vanished. […]

It took almost 200,000 years to reach our first billion (that was in 1804), but now we’re on a fantastic growth spurt, to 3 billion by 1960, another billion almost every 13 years since then.

The Mariana Trench is the deepest part of the world’s oceans. It is located in the western Pacific Ocean, to the east of the Mariana Islands.

The trench reaches a maximum-known depth of 10.994 km or 6.831 mi at the Challenger Deep, a small slot-shaped valley in its floor, at its southern end, although some unrepeated measurements place the deepest portion at 11.03 kilometres (6.85 mi).

The trench is not the part of the seafloor closest to the center of the Earth. This is because the Earth is not a perfect sphere: its radius is about 25 kilometres (16 mi) less at the poles than at the equator. As a result, parts of the Arctic Ocean seabed are at least 13 kilometres (8.1 mi) closer to the Earth’s center than the Challenger Deep seafloor.

For nearly a decade, scientists have told city and state officials that New York faces certain peril: rising sea levels, more frequent flooding and extreme weather patterns. The alarm bells grew louder after Tropical Storm Irene last year, when the city shut down its subway system and water rushed into the Rockaways and Lower Manhattan.

On Tuesday, as New Yorkers woke up to submerged neighborhoods and water-soaked electrical equipment, officials took their first tentative steps toward considering major infrastructure changes that could protect the city’s fragile shores and eight million residents from repeated disastrous damage. […]

“The construction of this city did not anticipate these kinds of situations. We are only a few feet above sea level,” Mr. Cuomo said during a radio interview. “As soon as you breach the sides of Manhattan, you now have a whole infrastructure under the city that fills — the subway system, the foundations for buildings,” and the World Trade Center site. […]

After rising roughly an inch per decade in the last century, coastal waters in New York are expected to climb as fast as six inches per decade, or two feet by midcentury, according to a city-appointed scientific panel. That much more water means the city’s flood risk zones could expand in size. […]

What scientists, who have devoted years of research to the subject, now fear most is that, as soon as the cleanup from this storm is over, the public will move on.

Bas Jan Ader (1942-1975) was a conceptual artist, performance artist, photographer and filmmaker. He lived in Los Angeles for the last 10 years of his life. […]

Ader was lost at sea while attempting a single-handed west-east crossing of the Atlantic in a 13 ft pocket cruiser, a modified Guppy 13 named “Ocean Wave.” The passage was part of an art performance titled “In Search of the Miraculous.” Radio contact broke off three weeks into the voyage, and Ader was presumed lost at sea. The boat was found after 10 months, floating partially submerged 150 miles West-Southwest of the coast of Ireland. His body was never found.

Heaven is hotter than hell

Proof:

The temperature of heaven can be rather accurately computed. Our authority is the Bible, Isaiah 30:26 reads,

Moreover, the light of the moon shall be as the light of the sun and the light of the sun shall be sevenfold as the light of seven days.

Thus, heaven receives from the moon as much radiation as the earth does from the sun, and in addition seven times seven (forty nine) times as much as the earth does from the sun, or fifty times in all. The light we receive from the moon is one ten-thousandth of the light we receive from the sun, so we can ignore that. With these data we can compute the temperature of heaven: The radiation falling on heaven will heat it to the point where the heat lost by radiation is just equal to the heat received by radiation. In other words, heaven loses fifty times as much heat as the earth by radiation. Using the Stefan-Boltzmann fourth power law for radiation

(H/E)⁴ = 50

where E is the absolute temperature of the earth, 300°K (273+27). This gives H the absolute temperature of heaven, as 798° absolute (525°C).

The exact temperature of hell cannot be computed but it must be less than 444.6°C, the temperature at which brimstone or sulfur changes from a liquid to a gas. Revelations 21:8: But the fearful and unbelieving… shall have their part in the lake which burneth with fire and brimstone.” A lake of molten brimstone [sulfur] means that its temperature must be at or below the boiling point, which is 444.6°C. (Above that point, it would be a vapor, not a lake.)

We have then, temperature of heaven, 525°C. Temperature of hell, less than 445°C. Therefore heaven is hotter than hell.

Refutation:

In Applied Optics (1972, 11 A14) there appeared a calculation of the respective temperatures of Heaven and Hell. That of Heaven was computed by substituting the values given in Isaiah 30 26 in the Stefan-Boltzman radiation law. […] This is hard to find fault with. The assessment of the temperature of Hell stands, I suggest, on less firm ground.

Sweden’s successful waste-to-energy program converts household waste into energy for heating and electricity. But they’ve run into an unusual problem: they simply aren’t generating enough trash to power the incinerators, so they’ve begun importing waste from European neighbors. […]

Sweden has recently begun to import about eight hundred thousand tons of trash from the rest of Europe per year to use in its power plants. The majority of the imported waste comes from neighboring Norway because it’s more expensive to burn the trash there and cheaper for the Norwegians to simply export their waste to Sweden.

In the arrangement, Norway pays Sweden to take the waste off their hands and Sweden also gets electricity and heat. But dioxins in the ashes of the waste byproduct are a serious environmental pollutant. Ostlund explained that there are also heavy metals captured within the ash that need to be landfilled. Those ashes are then exported to Norway.

Plate tectonics is the process that underpins much of our understanding of the Earth. It explains many aspects of the Earth, from magnetic patterns in oceanic rocks to the distribution of plants and animals. How unusual is it? Well, it doesn’t seen to be happening on other rocky planets in our solar system. Many geologists have argued that plate tectonics wasn’t active during the earth’s early history. As astronomers find many rocky planets in other solar systems, the question of understanding how ‘typical’ plate tectonics has implications beyond the earth. How long has it been going on – how old is it?
