Antarctica Protected From Global Warming By Hole In Ozone Layer


From The Scotsman:

A HUGE hole in the ozone layer has protected Antarctica from the impacts of global warming, according to scientists.
The temperature across Antarctica has not risen over the past 30 years and there has been a 10 per cent increase in the amount of sea ice appearing during winter.

Climate change sceptics regularly cite the lack of warming in Antarctica as evidence
global warming is not happening.

Buried Treasure

Face from a Coffin. Egypt, Third Intermediate Period, 1075-656 B.C. Coffin sculptures such as this were first covered with gesso as a primer before being painted. The gesso and most of the paint have worn off, revealing the wood underneath. Three thousand years later, you can still see the sculptor's hand in the carving marks.

From Archaeology News/Forbes:

The Brooklyn Museum scours its archives for a show on ancient Egypt.

Besides ensuring tourism and providing storylines for scores of feature films, the mystique of ancient Egypt also launched a specific sort of museum show that has become de rigueur for large institutions: the blockbuster. When the traveling exhibition Treasures of Tutankhamun came to the Metropolitan Museum of Art in 1979, it broke all the museum's previous attendance records and became famous enough to merit a spoof on Saturday Night Live.

From The Air & Space Smithsonian:

It's all about the solar beta angle.


While it was a hydrogen leak on the pad that forced NASA to scrub the launch of space shuttle mission STS-127 on June 17, one main reason the agency had to wait several weeks to try again was something called a “solar beta angle cut-out.”

Solar what?

Before sending a shuttle aloft, mission planners carefully calculate the angle defined by its orbital plane around Earth and a line drawn from the center of Earth to the center of the sun. This “solar beta angle” changes constantly as Earth moves around the sun and the shuttle’s orbital plane precesses, or slowly shifts, due to the gravitational tug from Earth’s equatorial bulge.

Solar Panel Costs 'Set To Fall'

The fall in cost is due to the increased lifetime, the institute says

From the BBC:

The cost of installing and owning solar panels will fall even faster than expected according to new research.

Tests show that 90% of existing solar panels last for 30 years, instead of the predicted 20 years.

According to the independent EU Energy Institute, this brings down the lifetime cost.

The institute says the panels are such a good long-term investment that banks should offer mortgages on them like they do on homes.

Space Shuttle Jr. -- The Air & Space Smithsonian

After 2010, the only spaceplane in the U.S. inventory will be the Air Force's mysterious X-37.

It's been a long wait—in some ways, more than 50 years—but in April 2010, the U.S. Air Force is scheduled to launch an Atlas V booster from Cape Canaveral, Florida, carrying the newest U.S. spacecraft, the unmanned X-37, to orbit. The X-37 embodies the Air Force's desire for an operational spaceplane, a wish that dates to the 1950s, the era of the rocket-powered X-15 and X-20. In other ways, though, the X-37 will be picking up where another U.S. spaceplane, NASA's space shuttle, leaves off.

Peat Fires Drive Temperatures Up: Burning Rainforests Release Huge Amounts of Greenhouse Gases


From Science Daily:

ScienceDaily (Nov. 29, 2009) — Peatlands, especially those in tropical regions, sequester gigantic amounts of organic carbon. Human activities are now having a considerable impact on these wetlands. For example, drainage projects, in combination with the effects of periodic droughts, can lead to large-scale fires, which release enormous amounts of carbon dioxide (CO2) into the atmosphere, and thus contribute to global warming. Using laser-based measurements, Professor Florian Siegert and his research group at Ludwig-Maximilians-Universität (LMU) in Munich have now estimated the volume of peat burned in such fires with unprecedented accuracy.

What's The Environmental Impact Of Going Into Space?


Dirty Rockets -- Slate

We hear so much about the environmental impacts of transportation. What about space travel? How do rockets affect the atmosphere?

There's a simple reason why we hear a lot more about cars, ships, and planes than we do about rocket ships: There are lot more of them. Each flight into space does have a small impact on the planet it leaves behind, but—for the moment, at least—these launchings are very rare. Only a couple of rockets blast off every week around the world. As a result, space travel doesn't register on most environmentalists' radars.

The Great Climate Change Science Scandal


From Times Online:


Leaked emails have revealed the unwillingness of climate change scientists to engage in a proper debate with the sceptics who doubt global warming.

The storm began with just four cryptic words. “A miracle has happened,” announced a contributor to Climate Audit, a website devoted to criticising the science of climate change.

“RC” said nothing more — but included a web link that took anyone who clicked on it to another site, Real Climate.

There, on the morning of November 17, they found a treasure trove: a thousand or so emails sent or received by Professor Phil Jones, director of the climatic research unit at the University of East Anglia in Norwich.

Jones is a key player in the science of climate change. His department’s databases on global temperature changes and its measurements have been crucial in building the case for global warming.

Solar Power Costs 50% Lower Than Last Year


From Scientific American:

New research by leading alternative energy research firm New Energy Finance finds that solar power will cost less by about 50% at the end of 2009 compared to the end of 2008.

The costs are pre-subsidy, so they could be much lower if you take better government subsidies into account.

But it isn’t only solar that’s down in cost. It’s other renewable energy sources, too.
The research company found that equipment costs (in solar, wind, and other sectors) decreased throughout the year but these were offset by increasing financing costs. However, equipment prices are expected to continue falling whereas the financing market is expected to get better.
