Ice core samples from Mount Everest that represent 800 years of atmospheric history contain much higher levels of certain metals in the last three decades than in the previous seven centuries. The metals are linked to the rising use of fossil fuels in Asia during that same time period.
Economic growth and more burning of fossil fuels by industries and cars in central Asia since the 1970s has resulted in higher levels of metals deposited in recent layers of ice collected from Mount Everest.
Data from a recent study that examined the cores from the Himalayan Mountains are the first to show that levels of arsenic, molybdenum, tin and antimony in the ice samples have sharply increased during the last 30 years when compared to the previous 700 years. During those centuries, the metal levels varied but were fairly stable.

The federal government is encouraging farmers to spread a chalky waste from coal-fired power plants on their fields to loosen and fertilize soil even as it considers regulating coal wastes for the first time.
The material is produced by power plant "scrubbers" that remove acid rain causing sulfur dioxide from plant emissions. A synthetic form of the mineral gypsum, it also contains mercury, arsenic, lead and other heavy metals.
The U.S. Environmental Protection Agency says those toxic metals occur in only tiny amounts that pose no threat to crops, surface water or humans. But some environmentalists say too little is known about how the material affects crops, and ultimately human health, for the government to suggest that farmers use it on their land.

If you want to understand how people will remember the Obama climate legacy, a few facts tell the tale: By the time Obama leaves office, the U.S. will pass Saudi Arabia as the planet's biggest oil producer and Russia as the world's biggest producer of oil and gas combined. In the same years, even as we've begun to burn less coal at home, our coal exports have climbed to record highs. We are, despite slight declines in our domestic emissions, a global-warming machine: At the moment when physics tell us we should be jamming on the carbon brakes, America is revving the engine.

THE city government yesterday freed 40,000 hairy crabs into the mouth of Yangtze River near the Qingcaosha Reservoir, the first step in a five-year campaign to repair the ecosystem to improve the water quality in the reservoir that provides tap water for millions of residents.
The hairy crabs will help establish a complete food chain in the river to help more fish and other aquatic animals survive in the river...

The massive drought that has dried out Texas over the past year has killed as many as half a billion trees, according to new estimates from the Texas Forest Service.

The US Department of Energy (DOE) is embarking on a US $100-million research programme to investigate what will happen to the 1,500 billion tonnes of organic carbon locked up in frozen soils of the far northern permafrost when they thaw in the rapidly warming Arctic climate.

The countdown to the apocalypse is on.
We're one year away from Dec. 21, 2012, the date that the ancient Mayan Long Count calendar allegedly marked as the end of an era that would reset the date to zero and signal the end of humanity.
But will it?... Believers have taken the end-of-the world fears to the Internet with hundreds of thousands of websites and blogs. Yet others are capitalizing on the heightened interest. Films depicting the end of the world - including the 2009 movie, "2012" - are contributing to the mounting hype as well as to misinformation, experts say.

A new global body dedicated to environmental stewardship is needed to prevent a repeat of the deadlock which undermined the Copenhagen climate change summit, Gordon Brown will say tomorrow.
The UN’s consensual method of negotiation, which requires all 192 countries to reach agreement, needs to be reformed to ensure that the will of the majority prevails, he feels. The Prime Minister will say: “Never again should we face the deadlock that threatened to pull down those talks. Never again should we let a global deal to move towards a greener future be held to ransom by only a handful of countries. One of the frustrations for me was the lack of a global body with the sole responsibility for environmental stewardship..."

Man's best friend could be one of the environment's worst enemies, according to a new study which says the carbon pawprint of a pet dog is more than double that of a gas-guzzling sports utility vehicle.
But the revelation in the book "Time to Eat the Dog: The Real Guide to Sustainable Living" by New Zealanders Robert and Brenda Vale has angered pet owners who feel they are being singled out as troublemakers.
The Vales, specialists in sustainable living at Victoria University of Wellington, analysed popular brands of pet food and calculated that a medium-sized dog eats around 164 kilos (360 pounds) of meat and 95 kilos of cereal a year.
Combine the land required to generate its food and a "medium" sized dog has an annual footprint of 0.84 hectares (2.07 acres) -- around twice the 0.41 hectares required by a 4x4 driving 10,000 kilometres (6,200 miles) a year, including energy to build the car.

The kinds of increases in atmospheric carbon dioxide taking place today could have a significantly larger effect on global temperatures than previously thought, according to a new study led by Yale University geologists. Their findings appear December 20 in the advanced online edition of Nature Geoscience.... Their reconstructed CO2 concentrations for the past five million years was used to estimate Earth-system climate sensitivity for a fully equilibrated state of the planet, and found that a relatively small rise in CO2 levels was associated with substantial global warming 4.5 million years ago. They also found that the global temperature was 2 to 3 degrees Celsius higher than today while CO2 levels were only between about 365 and 415 parts per million (ppm) -- similar to today's concentration of about 386 ppm.... "Since there is no indication that the future will behave differently than the past, we should expect a couple of degrees of continued warming even if we held CO2 concentrations at the current level."

Appearing at Washington's Children's Hospital with public health leaders at her side, Environmental Protection Agency Administrator Lisa Jackson on Wednesday unveiled the nation's first-ever national standards for mercury and other toxic air pollution from power plants.
The sweeping regulations -- mandated by Congress in 1990 and delayed by prolonged litigation, lobbying, and legislative battles --will require utilities to cut at least 90 percent of their emissions of mercury, a neurotoxin known to cause brain damage and other health problems, particularly in developing fetuses and young children...EPA says the rule will prevent up to 11,000 premature deaths and prevent thousands of respiratory illnesses, which could translate into $90 billion in health and economic benefits a year.
