Greenhouse Gases Continue To Climb Despite Economic Slump
Two of the most important climate change gases increased last year, according to a preliminary analysis for NOAA’s annual greenhouse gas index, which tracks data from 60 sites around the world. Researchers measured an additional 16.2 billion tons of carbon dioxide (CO2) -- a byproduct of fossil fuel burning -- and 12.2 million tons of methane in the atmosphere at the end of December 2008. This increase is despite the global economic downturn, with its decrease in a wide range of activities that depend on fossil fuel use.
"Only by reducing our dependence on fossil fuels and increasing energy production from renewable resources will we start to see improvements and begin to lessen the effects of climate change," said scientist Pieter Tans of NOAA's Earth System Research Laboratory in Boulder, Colo. "At NOAA we have monitored carbon dioxide emissions and other greenhouses gases for decades and will continue to do so to help assess the situation and advise decision makers." ...

As World Warms, Water Levels Dropping In Major Rivers
Rivers in some of the world's most populous regions are losing water, according to a comprehensive study of global stream flows. The research, led by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo., suggests that the reduced flows in many cases are associated with climate change, and could potentially threaten future supplies of food and water... The scientists, who examined stream flows from 1948 to 2004, found significant changes in about one-third of the world's largest rivers. Of those, rivers with decreased flow outnumbered those with increased flow by a ratio of about 2.5 to 1. ...

from London Daily Telegraph:
Climate change could speed up as pollution decreases
The new research found that plants have been taking in more carbon dioxide over the last 40 years because pollution makes it easier for plants to convert sunlight to energy.
However as the world produces more electricity from renewables and transport is made cleaner, the skies will be clearer - slowing the ability of plants to absorb the greenhouse gas and therefore contributing to global warming. The study, published in Nature, warned that the reduced ability of plants to absorb carbon dioxide as the air becomes cleaner makes it even more important to cut emissions in the future....The increase in the amount of carbon dioxide, which is a greenhouse gas, may have helped to slow global warming. However as the world cuts pollution it will speed up again. ...

Dust Storms Escalate, Prompting Environmental Fears
The Colorado Rockies, including the headwaters of the Colorado River and the Rio Grande, have experienced 11 serious dust storms this year, a record for the six years researchers have been tracking them.
More important, an increasing amount of airborne dust is blanketing the region, affecting how fast the snowpack melts, when local plants bloom and what quality of air residents are breathing.
The dust storms are a harbinger of a broader phenomenon, researchers say, as global warming translates into less precipitation and a population boom intensifies the activities that are disturbing the dust in the first place. ...

Earth in the balance
...the overall condition of the planet has worsened since 1970, as its human population has nearly doubled to 6.8 billion. Natural resources like fresh water and tropical forests are dwindling, and it's becoming more difficult to hide our waste, much of which is plastic and will be around long after our children -- and theirs -- have lived through future Earth Days.
But after nearly 40 years, saving the Earth is finally at or near the forefront of American politics, pushed there by growing awareness of global climate change and a national energy policy that leans too heavily on imported oil and other limited fossil fuels.... ...

Worst Environmental Problem? Overpopulation, Experts Say
Overpopulation is the world's top environmental issue, followed closely by climate change and the need to develop renewable energy resources to replace fossil fuels, according to a survey of the faculty at the SUNY College of Environmental Science and Forestry (ESF)... Overpopulation came out on top, with several professors pointing out its ties to other problems that rank high on the list.
"Overpopulation is the only problem," said Dr. Charles A. Hall, a systems ecologist. "If we had 100 million people on Earth -- or better, 10 million -- no others would be a problem." ...

As Climate Warms, Species May Need to Migrate or Perish
...A number of studies indicate that global warming will rob many species of their current habitat, pushing them towards extinction. Some conservation biologists argue that the only way to save some species may be to move them to new ranges that they can’t get to themselves.
This strategy — which goes by various names including assisted migration, assisted colonization, and, most recently, managed relocation — only emerged in the scientific literature in 2007. Over the past two years it has attracted widespread interest. A number of scientists are now investigating how they can pick new homes for endangered species and move them safely. ...

South Korea lights the way on carbon emissions with its £23bn green deal
The secretary for future vision is considering how many South Koreans it takes to change a million lightbulbs. No joke.
Kim Sang-hyo, the president's extravagantly titled right-hand man, is trying to create more than 940,000 green jobs and improve his country's energy efficiency at the same time. Switching every bulb in every public building in South Korea to light-emitting diodes by the end of this year is one, very small, element in the master plan of what has been described as the greenest new deal on the planet....Over the next four years, the government promises to build a million green homes, improve the energy efficiency of a million more, invest £1.2bn on research into low-carbon technologies and spend £4.8bn on high-speed railways and other forms of "clean" transport. ...

Keeping Slim Is Good For The Planet, Say Scientists
Maintaining a healthy body weight is good news for the environment, according to a study which appears April 20 in the International Journal of Epidemiology. Because food production is a major contributor to global warming, a lean population, such as that seen in Vietnam, will consume almost 20 percent less food and produce fewer greenhouse gases than a population in which 40 percent of people are obese (close to that seen in the USA today)... When it comes to food consumption, moving about in a heavy body is like driving around in a gas guzzler', say the authors. ...

Berkeley mayor gives up his car for the bus
Some mayors tool around in Priuses and hybrid Civics. But Berkeley Mayor Tom Bates has taken green transit a step further. No more cars for him, at all.
The 71-year-old mayor is trading in his 2001 Volvo for an AC Transit pass and a sturdy pair of walking shoes.
"I'm trying to reduce my carbon footprint to the absolute minimum," he said. "I figure, if I really want to go someplace I can just rent a car."
Bates' long farewell to the Volvo began about a year ago, when he started walking to work as a way to lose weight and stay in shape. The 18-minute trek from his home in South Berkeley to City Hall was so invigorating he started walking everywhere he could - to Berkeley Bowl, the BART station, city council meetings. ...

China considers setting targets for carbon emissions
The Chinese government is for the first time considering setting targets for carbon emissions, a significant development that could help negotiations on a Kyoto successor treaty at Copenhagen later this year, the Guardian has learned.
Su Wei, a leading figure in China's climate change negotiating team, said that officials were considering introducing a national target that would limit emissions relative to economic growth in the country's next five-year plan from 2011... While that is a minority view and final decisions are some way off, the proposals are striking because they are at odds with China's official negotiating stance. ...

PERU: Water Isn't for Everyone
The melting of glaciers resulting from climate change and the lack of adequate water management policies seem to be the main causes behind the water shortages that are fuelling conflicts in Peru.
This warning is being sounded from a variety of sectors.
Nearly 50 percent of the 218 social conflicts recorded by the national ombudsman’s office as of February 2009 were triggered by socio-environmental problems, many of them related to water management issues, states the report "Water Faces New Challenges: Actors and Initiatives in Ecuador, Peru and Bolivia", published by the international anti-poverty organisation Oxfam on Mar. 20.
Two southern departments, Moquegua and Arequipa, are at loggerheads over water. And rural communities in the Andean highlands region along the Yauca River have experienced violent clashes that have even claimed lives. ...
