NOAA, NASA: Antarctic ozone hole second smallest in 20 years

Warmer air temperatures high above the Antarctic led to the second smallest seasonal ozone hole in 20 years, according to NOAA and NASA satellite measurements. This year, the average size of the ozone hole was 6.9 million square miles (17.9 million square kilometers). The ozone layer helps shield life on Earth from potentially harmful ultraviolet (UV) radiation that can cause skin cancer and damage plants.

The Antarctic ozone hole forms in September and October, and this year, the hole reached its maximum size for the season on Sept. 22, stretching to 8.2 million square miles (21.2 million square kilometers), roughly the area of the United States, Canada and Mexico combined. In comparison, the largest ozone hole recorded to date was in 2000 at 11.5 million square miles (29.9 million square kilometers).

The Antarctic ozone hole began making a yearly appearance in the early 1980s, caused by chlorine released by manmade chemicals called chlorofluorocarbons or CFCs. The chlorine can rapidly break apart ozone molecules in certain conditions, and the temperature of the lower stratosphere plays an important role.

“It happened to be a bit warmer this year high in the atmosphere above Antarctica, and that meant we didn’t see quite as much ozone depletion as we saw last year, when it was colder,” said Jim Butler with NOAA’s Earth System Research Laboratory in Boulder, Colo.

Another DOE-Backed Solar Company Goes Bankrupt

A solar company that got a multi-million-dollar grant from the Department of Energy earlier this year announced Wednesday that it will file for Chapter 11 bankruptcy protection, making it the second taxpayer-backed green energy company to file for bankruptcy this week.

Satcon Technology Corp. announced the decision in a Wednesday news release. “This has been a difficult time for Satcon,” president and CEO Steve Rhoades said. “After careful consideration of available alternatives, the Company’s Board of Directors determined that the Chapter 11 filings were a necessary and prudent step, allowing the Company to continue to operate while giving us the opportunity to reorganize with a stronger balance sheet and capital structure.”

Satcon received a $3 million DOE grant in January to develop “a compact, lightweight power conversion device that is capable of taking utility-scale solar power and outputting it directly into the electric utility grid at distribution voltage levels—eliminating the need for large transformers.”

President Obama’s Taxpayer-Backed Green Energy Failures

It is no secret that President Obama’s and green-energy supporters’ (from both parties) foray into venture capitalism has not gone well. But the extent of its failure has been largely ignored by the press. Sure, single instances garner attention as they happen, but they ignore past failures in order to make it seem like a rare case.

The truth is that the problem is widespread. The government’s picking winners and losers in the energy market has cost taxpayers billions of dollars, and the rate of failure, cronyism, and corruption at the companies receiving the subsidies is substantial. The fact that some companies are not under financial duress does not make the policy a success. It simply means that our taxpayer dollars subsidized companies that would’ve found the financial support in the private market.

So far, 36 companies that were offered federal support from taxpayers are faltering — either having gone bankrupt or laying off workers or heading for bankruptcy. This list includes only those companies that received federal money from the Obama Administration’s Department of Energy and other agencies. The amount of money indicated does not reflect how much was actually received or spent but how much was offered. The amount also does not include other state, local, and federal tax credits and subsidies, which push the amount of money these companies have received from taxpayers even higher.

Global warming stopped 16 years ago, reveals Met Office report quietly released... and here is the chart to prove it

• The figures reveal that from the beginning of 1997 until August 2012 there was no discernible rise in aggregate global temperatures
• This means that the ‘pause’ in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996

The world stopped getting warmer almost 16 years ago, according to new data released last week. 

 The figures, which have triggered debate among climate scientists, reveal that from the beginning of 1997 until August 2012, there was no discernible rise in aggregate global temperatures.

This means that the ‘plateau’ or ‘pause’ in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996. Before that, temperatures had been stable or declining for about 40 years.

Human Greenhouse Gas Emissions Traced to Roman Times

By burning wood, humans have been significant contributors to greenhouse gas emissions as far back as the Roman Empire, researchers say.

The finding may lead scientists to rethink some aspects of climate change models, which assume humans weren't responsible for much greenhouse gas before the Industrial Revolution.
"It was believed that emissions started in 1850. We showed that humans already started to impact greenhouse effects much before," study co-author Célia Sapart of Utretcht University in the Netherlands said.
Methane is a potent greenhouse gas with 20 times the warming power of carbon dioxide, Sapart told LiveScience. Forest fires, wetlands and volcanic eruptions naturally release methane into the atmosphere. But human actions, such as raising cattle or burning fossil fuel, now account for more than half of the methane released.
