Mangrove Destruction Accounts For 10% Of CO2 Emissions
Posted by Washington Post: Juliet Eilperin on April 4th, 2011
REDORBIT: According to a study released on Sunday, mangroves are in important bulkhead against climate change.
The study found that destruction of these tropical coastal woodlands accounts for about 10 percent of carbon dioxide emissions from deforestation, which is the second largest source of CO2 after fossil fuel combustion.
Fewer trees would lead to less CO2 being absorbed from the air and would also release carbon stocks that have been accumulating in shallow-water sediment over millennia.

National Science Foundation: "Epidemiological" Study Demonstrates Climate Change Effects on Forests
Study of 27,000 trees shows early spring warming, summer drought as major factors
Some 280,000 tree-years of data show that magnolias are vulnerable to climate change.
An 18-year study of 27,000 individual trees by National Science Foundation (NSF)-funded scientists finds that tree growth and fecundity--the ability to produce viable seeds--are more sensitive to climate change than previously thought.
The results, published...

AFP: Mangroves, which have declined by up to half over the last 50 years, are an important bulkhead against climate change, a study released on Sunday has shown for the first time.
Destruction of these tropical coastal woodlands accounts for about 10 percent of carbon dioxide emissions from deforestation, the second largest source of CO2 after fossil fuel combustion, the study found.
Fewer trees not only mean less CO2 absorbed from the air, but also the release of carbon stocks that have been accumulating...
Carbon-rich mangroves ripe for conservation

Nature: Carbon-rich mangroves ripe for conservation
Failing to preserve mangrove forests could cause sizeable carbon emissions.
Until now, the amount of carbon locked up in mangrove forests was largely unknown
Mangrove forests in tropical regions of the Indian and Pacific Oceans store more carbon than previously recognized, according to a study published today in Nature Geoscience1. The findings indicate that much of the carbon in such forests is found in the surrounding soil, which is rich in organic...
Japan nuclear plant to release radioactive water into sea

The operator of Japan's Fukushima nuclear plant has started breaking its own regulations by discharging 11,500 tonnes of contaminated water into the Pacific to make space for more highly radioactive liquid.
The release of water that is 100 times the legal limit is an unprecedented breach of...

Penan community’s ancestral land destroyed
Posted by Washington Post: Juliet Eilperin on April 4th, 2011
Aliran: Hundreds of Penan facing eviction to make way for the Murum Dam are horrified to learn that the forest in the proposed resettlement area is being destroyed, reports Tomasz Johnson.
Hundreds of indigenous people in Borneo who are due to be evicted from their land to make way for a giant hydroelectric dam have discovered that the rainforest they hoped to move to is being destroyed.
The Penan are being forced to move by the Sarawak state government to allow the billion-dollar Murum dam project...
Japan may review CO2 cut targets
Posted by Washington Post: Juliet Eilperin on April 4th, 2011
Ria Novosti: Japan may review its greenhouse gas emission reduction target in the wake of a nuclear crisis set off by last month's massive earthquake and tsunami, Chief Cabinet Secretary Yukio Edano was quoted by Japanese media as saying.
He stressed, however, that the government has no definitive plans yet to review its climate change goal of cutting greenhouse gas emissions 25% by 2020 from 1990 levels, and it will depend on Japan's ability to tackle its worst ever nuclear accident at the Fukushima Daiichi...
Japan: Open door: Explaining the Fukushima crisis
Posted by Guardian: Chris Elliott on April 4th, 2011
Guardian: The still-unfolding tragedy of Japan may be told simply through the statistics of death and destruction. However, the scientific complexity underlying the crisis at the Fukushima Daiichi nuclear power plant is much harder to report.
There are many kinds of radiation and more than one view as to the short- and long-term effects of exposure. Trying to explain in a clear, accurate fashion what is happening to the plant's damaged reactors and the workers struggling to bring the plant under control...
Wildfires rage across five states of parched Southwest
Posted by Reuters: Elliott Blackburn on April 4th, 2011
Reuters: Wildfires fed off what were described as "perfect" conditions for burning again on Monday across drought-stricken Texas and nearby states.
High temperatures, dry grass, gusting winds and dry air contributed to fires that began over the weekend in Texas, Kansas, Colorado, Oklahoma and New Mexico, said Patrick Slattery, a spokesman for the National Weather Service.
More than three quarters of Texas was under severe or extreme levels of drought, according to the Texas Forest Service. Hot, dry...
