NASA: Warming Will Transform Natural World

21st Century Ecological Sensitivity - Changes in Plant Species

Global warming could bring a major transformation for Earth's plants and animals over the next century, a NASA study says, driving nearly half the planet's forests, grasslands and other vegetation toward conversion into radically different ecosystems.

The ecological stress could give a boost to invasive species, but at the expense of natives, reducing the diversity of plants and animals overall.

History Is Made in Australia

This is a historic moment. Australia's Parliament has put the nation's first carbon price into law. With this vote, the world has turned a pivotal corner in the collective effort to solve the climate crisis. This success is the result of the tireless work of an unprecedented coalition that came together to support the legislation, the leadership of Prime Minister Gillard, and the courage of legislators to take a vote that helps to safeguard the future of all Australians.

I have spent enough time in Australia to know that their spirit of independence as a people cannot be underestimated. As the world's leading coal exporter, there's no doubt that opposition to this legislation was fierce. But through determination and commitment, the voice of the people of Australia has rung out loud and clear.

Today, we celebrate. Tomorrow, we do everything we can to ensure that this legislation is successful.

Xenon Means Recent Fission in Reactor 2

Tepco claims level in gas too small to affect shutdown effort

Tokyo Electric Power Co. said Wednesday that some of the melted fuel in reactor 2 at the Fukushima No. 1 nuclear plant may have triggered a brief criticality event.

Although the Nuclear and Industrial Safety Agency said there have been no drastic changes in the reactor's temperature and pressure level, and the reactor itself is stable overall, the discovery may mean the goal of Tepco and the government to achieve cold shutdown of all three crippled reactors by the end of the year may not be possible.

Suggesting that criticality, or a sustained nuclear chain reaction, may have occurred temporarily, or partially, Tepco said one hundred thousandth of a becquerel per cubic centimeter of xenon-133 and xenon-135 was detected in gas samples.

New Trouble Reported at Japan Nuclear Plant

TOKYO — Officials detected a radioactive gas associated with nuclear fission at Japan's tsunami-damaged atomic power plant Wednesday, indicating there could be a new problem at one of its reactors. They injected a substance that neutralizes nuclear reactions as a precaution.

Gas from inside the reactor indicated the presence of radioactive xenon, which could be the byproduct of unexpected nuclear fission. Boric acid was being injected through a cooling pipe as a countermeasure because it can counteract nuclear reactions.

Arctic Ozone Loss 'Unprecedented,' Scientists Say

Environment Canada cuts could disable future Canadian measurements

Unusual winter weather in the atmosphere high above the Earth's surface caused an "unprecedented" loss of protective ozone over the Arctic this year, scientists say.

The ozone layer in the stratosphere, located about 15 to 35 kilometres above the Earth's surface, protects the Earth from the sun's ultraviolet rays and harmful effects such as skin cancer. While an ozone hole has formed in the stratosphere over the Antarctic each spring since the mid 1980s, a paper published in Nature on Sunday marks the first time scientists have reported a comparable loss over the Arctic.

Explosion at French Nuclear Waste Plant

An explosion at a French nuclear waste processing plant that killed one person and injured four others sparked fears of a radioactive leak on Monday.

An emergency safety cordon was thrown around the Marcoule nuclear site near Nimes in the south of France immediately after a furnace used to melt nuclear waste exploded and caused a fire. It was lifted later in the day after France's nuclear safety agency, the Autorité de Sûreté Nucléaire (ASN), said there was no danger to the public.

Reports said the body of one male worker at the plant had been "found carbonised", but there was no evidence that the explosion had caused any radioactive leak, though the ASN admitted there was the "possibility of a leak of low-level radioactivity, but no shooting of radioactivity in the air". There was no information as to the cause of the explosion.

The accident came just a week after the French president, Nicolas Sarkozy, bucked the anti-nuclear trend following Japan's Fukushima disaster and pledged €1bn (£860m) of new investment in atomic power.
