Some embarrassing findings for the Greenies

The two current articles below are amusing to read in conjunction. The facts sure are pesky



OZONE: A GREAT GREENIE "SUCCESS" HAS ACHIEVED NOTHING (SURPRISE!)

It shows how dubious Greenie atmospheric physics can be

A satellite has detected record losses of ozone over Antarctica this year, further damaging the shield that protects Earth from cancer-causing ultraviolet rays. In the past decade, the level of ozone in Earth's atmosphere has fallen by about 0.3 per cent, increasing the risk of skin cancer, cataracts and harm to marine life, the European Space Agency said overnight. The presence of a hole in the ozone layer over the Antarctic was first recognised in 1985.

The World Meteorological Organisation (WMO) said earlier this month that the hole was nearing its record size of 29 million sq km set in 2000. However, the depth of the hole was greater this year than in 2000, bringing the amount of lost ozone to 40 million tonnes on October 2, beating 2000's record of 39 million tonnes, ESA said in a statement. The ozone loss over Antarctica is calculated by measuring the hole's area and depth. "Such significant ozone loss requires very low temperatures in the stratosphere combined with sunlight," ESA atmospheric engineer Claus Zehner said. "This year's extreme loss of ozone can be explained by the temperatures above Antarctica reaching the lowest recorded in the area since 1979," Mr Zehner said. [Hey! Where did the global warming go??]

The WMO and the U.N. Environment Program (UNEP) said in August that the protective layer may return to pre-1980 levels by 2049 over much of Europe, North America, Asia, Australasia, Latin America and Africa. The agencies said that in Antarctica, ozone layer recovery would likely be delayed until 2065. Chlorofluorocarbons (CFCs) containing chlorine and bromine have been blamed for thinning the ozone layer because they attack ozone molecules, causing them to break apart. Many CFCs, once commonly used in refrigeration, air conditioning and industrial cleaning, were banned by the 1985 Vienna Convention and its Montreal Protocol of 1987. Despite that, CFCs had still not vanished from the air, ESA said.

Air samples show recent build-up of CO2

Odd that the earth hasn't been warming up in recent years, then (See above)

The world's oldest library of airsamples has recorded the biggest increases in atmospheric carbon dioxide since sampling began in 1978. CSIRO air librarian Paul Fraser said the levels of the primary greenhouse gas have been growing at an increasing rate each year since 1978 and may reach an annual increase of two parts per million by the end of this year. Global CO2 levels have increased from 340ppm to 380ppm in the past 30 years due to combustion of fossil fuels. Mainstream climate scientists argue the world needs to stabilise levels to around 450ppm by 2050 to avoid the catastrophic impacts of climate change.

Dr Fraser said while the library had revealed CO2 emissions had grown by 70 per cent a year since the 1970s, methane emissions had stabilised in the past seven years. To find this data, the CSIRO captures a 40km-long sheet of clean air from the Southern Ocean as it blows through Cape Grim on the rugged northwest coast of Tasmania. Dr Fraser said the recording instrumentation was so sensitive that samples could be contaminated by the gases released by ships beyond the horizon. "We sometimes collect tanks and find that they are a bit strange and the assumption is that something has got into the airstream that we weren't aware of," Dr Fraser said. "You could have a drop in the wind and the local vegetation could impact on it, or maybe cows - so we like to keep the wind speed nice and high and the wind direction off the ocean."

Wind is sampled each season and stored in pressurised cylinders at the CSIRO Marine and Atmospheric research centre near Melbourne, where it is analysed for both greenhouse and ozone-depleting gases. While long-term trends are relatively stable, Dr Fraser said there was some natural variation as a result of El Nino and La Nina weather patterns and natural events such as the eruption of Mount Pinatubo in 1991 and the Indonesian bushfires in 1998.
