GREEN CONSTRUCTION: International Green Construction Code to “compliment [green building] . . . systems and standards already in place” by “standardizing and codifying sustainability”

Leadership in Energy and Environmental Design (LEED) certification standards—developed by the U.S. Green Building Council—already exist, but an effective more user-friendly set of codes or guidelines that provide a framework for integrating sustainability into new building construction or renovation efforts are the logical next step in bringing energy-efficiency or green building standards to a wider market. From Talk Radio News Service:

The creation of the International Green Construction Code (IGCC), a framework to measure sustainable building development, construction and use, was announced today by International Code Council CEO Richard Weiland, during a press conference atop the roof of the National Association of Realtors building.

The ‘Safe, Sustainable and by the Book’ IGC Code, which is expected to be completed by April 2010, will add sustainable initiatives to existing construction codes. The code in the works will also provide a routine set of guidelines that will be easy for local and state governments to implement for the creation and renovation of green buildings.

The IGCC will also aid in the reduction of a buildings carbon emissions, said American Institute of Architects CEO Christine McEntee.

“Buildings are the largest source of energy consumption and green house gas emissions in America. [In the U.S.] buildings consume about 40% of the energy produced and also produce the same percent of carbon emissions,” said McEntee.

“We are encouraged by the desire of our government and many across the United States and around the world to move forward in ways that will acknowledge how design, engineering, construction management and enforcement can create a greener america and a greener globe,” said Weiland.

WILDLIFE: Alligator photographed in Georgia with deer kill

The extraordinary images below show an American alligator (Alligator mississippiensis) with what appears to be a freshly killed adult white-tailed deer. I imagine if the gator didn’t find the deer dead fresh that it took the deer swimming or crossing the waterway or via ambush.

The American alligator was once an endangered species, but it is now considered a recovered species. However, as these great predators continue to recover, conflicts with people will likely become more common. Furthermore, primarily because of fear and ignorance, humans have historically targeted large predators (the gray wolf is a good example). From the U.S. Fish and Wildlife Service:

The sight of a 12 to 14 foot-long alligator is something south Georgia folks see occasionally, but few have seen one take an adult deer out to lunch. Actually — for lunch.

The photographs of this deer-eating alligator were taken from the air by Terri Jenkins, a U.S. Fish and Wildlife Service District Fire Management Officer. She was preparing to ignite a prescribed fire at Harris Neck National Wildlife Refuge, about 40 miles south of Savannah, Georgia, on March 4, 2004. The photo has

“One advantage of fire work is you get to see that 12-14 footers are common from Santee National Wildlife Refuge in South Carolina to Coastal South Carolina to Georgia’s coast,” said Jenkins. “It looks like the alligator population is doing extremely well.”

This one was at least 12-13 feet long. Jenkins said that some bull alligators have a 35 inch girth.

The Service uses a helicopter capable of igniting controlled burns by dropping flaming fuel-filled ping pong balls on pre-selected areas. She works throughout parts of North Carolina, South Carolina and Coastal Georgia refuges and fish hatcheries. The Service uses prescribed fire to improve habitat and reduce the risk of catastrophic wildfires.

A very large alligator was shot in Texas back in 2005, because it was living in someone’s back yard. From Brazosport Facts:

“The first time I really got an idea of the size of it was when they got it,” Anita Rogers said.

Spring is mating season for the reclusive animals and the bulls tend to roam, said Joe Goff, who is not only the game warden who shot the animal, but has a house behind the Rogerses.

“In the last two weeks, we’ve had a number of nuisance alligator calls,” Goff said.

But Friday’s took the cake. Normally, game wardens will capture the animals and turn them over to alligator farms. Not this one.

“He’s too big,” Goff said. “We couldn’t capture him, he’s too dangerous. He’ll eat the females.”

Goff said the alligator swam to within 3 feet of him. Goff shot him with a .22-caliber rifle.

“He’s blind in his left eye,” Goff said. “It was spooky.”

Goff said the alligator will be given to a nuisance hunter who puts bids in with the state and will pay for the animal. The hunter then will clean the carcass and sell the meat and hide for processing.

While alligators can be a danger to pets, they’re generally not a threat to humans, said Charles Mann, a zookeeper in the reptile and amphibian department at the Houston Zoo.

“Certainly an alligator that gets up to 13 feet long gets that way by being very wary and probably tries to shy away from anything that could hurt it, mainly people,” Mann said.

Mann estimated the animal had to be at least 12 to 15 years old, but could be much older, based on its size.

“They grow about a foot a year until they’re 7 or 8 feet long, then past that they grow slower,” Mann said. “The record for longevity would be 50 or 60 years.”

Anita Rogers said she kept her dogs in the fence when she first heard the stories and heard the bellowing, which she likened to a giant bullfrog.

The Rogerses are glad the reptile is gone, but they don’t have problems with the smaller ones in the water.

“They keep the bayou cleaned out,” Charles Rogers said.

Mann said the animals, which have been around for hundreds of millions of years, were almost wiped out before the federal government stepped in.

“It’s really a success story of the Endangered Species Act,” he said.

ASTRONOMY: Why don’t gas clouds in space dissipate?

Have you ever wondered why massive gas clouds in space don’t disperse or slowly vanish? TheBadAstronomer provides an explanation, but don’t ask a creationist.

NEPHOLOGY: Mysterious noctilucent cloud phenomenon increases; noctilucent cloud formations linked to space shuttle activity and possibly Tunguska explosion of 1908

Noctilucent CloudsNoctilucent clouds are extremely high-altitude atmospheric formations that glow at night. Furthermore, although these fascinating “clouds ride in the sky above 99.9 percent of the atmosphere and over 40 miles above the highest clouds . . . [and] skirt the lowest fringes of the aurora,”—so they are certainly suggestive of the auroras or northern and southern lights—they are an entirely different phenomenon. According to Wikipedia, noctilucent clouds

are tenuous cloud-like phenomena that are the “ragged-edge” of a much brighter and pervasive polar cloud layer called polar mesospheric clouds in the upper atmosphere, visible in a deep twilight. They are made of crystals of water ice. The name means roughly night shining in Latin. They are most commonly observed in the summer months at latitudes between 50° and 70° north and south of the equator.

They are the highest clouds in the Earth’s atmosphere, located in the mesosphere at altitudes of around 76 to 85 kilometers (47 to 53 mi). They are normally too faint to be seen, and are visible only when illuminated by sunlight from below the horizon while the lower layers of the atmosphere are in the Earth’s shadow. Noctilucent clouds are not fully understood and are a recently discovered meteorological phenomenon; there is no evidence that they were observed before 1885.

Noctilucent clouds can form only under very restrictive conditions; their occurrence can be used as a sensitive guide to changes in the upper atmosphere. Since their discovery the occurrence of noctilucent clouds has been increasing in frequency, brightness and extent. It is theorized that this increase is connected to climate change.

Noctilucent clouds are increasing and spreading into other latitudes. The observance of these clouds is also linked to solar activity, but it is thought that an increase in greenhouse gases may play a role too. More from New Scientist:

The clouds were first seen above polar regions in 1885, suggesting they may have been caused by the eruption of Krakatoa two years before. But in recent years the clouds have spread to latitudes as low as 40°, while also growing in number and getting brighter. The reason for the clouds’ spread is unclear, but some suspect it could be due to an increase in greenhouse gases. That’s because the gases actually cause Earth’s upper atmosphere to cool, and the clouds need cold temperatures to form.

Although the average number of noctilucent clouds has been increasing in recent decades, their abundance also seems to rise and fall with the sun’s 11-year cycle of activity. The clouds thrive when the sun is quiet and spews less ultraviolet radiation, which can destroy water needed to form the clouds and can keep temperatures too high for ice particles to form.

Because the sun has been abnormally quiet in recent years, noctilucent clouds could be especially bright and numerous this summer in the Northern hemisphere.

A recent study suggests “the Tunguska explosion of 1908 [was] caused by a comet hitting Earth . . . based on the behaviour of water vapour from the space shuttle’s exhaust” forming noctilucent clouds. From Xenophilia:

The research, accepted for publication (June 24, 2009) by the journal Geophysical Research Letters, published by the American Geophysical Union, connects the two events by what followed each about a day later: brilliant, night-visible clouds, or noctilucent clouds, that are made up of ice particles and only form at very high altitudes and in extremely cold temperatures.

“It’s almost like putting together a 100-year-old murder mystery,” said Michael Kelley, the James A. Friend Family Distinguished Professor of Engineering at Cornell who led the research team. “The evidence is pretty strong that the Earth was hit by a comet in 1908.” Previous speculation had ranged from comets to meteors.

The researchers contend that the massive amount of water vapor spewed into the atmosphere by the comet’s icy nucleus was caught up in swirling eddies with tremendous energy by a process called two-dimensional turbulence, which explains why the noctilucent clouds formed a day later many thousands of miles away.

.      .       .

The space shuttle exhaust plume, the researchers say, resembled the comet’s action.

A single space shuttle flight injects 300 metric tons of water vapor into the Earth’s thermosphere, and the water particles have been found to travel to the Arctic and Antarctic regions, where they form the clouds after settling into the mesosphere.

Kelley and collaborators saw the noctilucent cloud phenomenon days after the space shuttle Endeavour (STS-118) launched on Aug. 8, 2007. Similar cloud formations had been observed following launches in 1997 and 2003.

Following the 1908 explosion, known as the Tunguska Event, the night skies shone brightly for several days across Europe, particularly Great Britain — more than 3,000 miles away.
