Australia: Climate change to bring more heatwaves
Posted by AAP: Evan Schwarten on April 5th, 2011
AAP: Australia can expect more heatwaves, fewer cyclones and possibly more floods as a result of climate change, extreme weather experts say.
Research meteorologist Dr John McBride from the Centre for Australian Weather and Climate Research told reporters in Cairns it was clear that the predicted rise in global temperatures would result in more heatwaves.
"There will be more heatwaves, most certainly," he said.
However, he said the picture was less clear when it came to the impact of climate...

Radioactive water at 5 million times limit found at Japan plant
Posted by Reuters: Mayumi Negishi and Yoko Nishikawa on April 5th, 2011
Reuters: The operator of Japan's crippled nuclear power plant said on Tuesday it had found water with 5 million times the legal limit of radioactivity as it struggles for a fourth week to contain the world's biggest nuclear disaster in quarter of a century.
Underlining the concern over spreading radiation, the government said it was considering imposing radioactivity restrictions on seafood for the first time in the crisis after contaminated fish were found in seas well south of the damaged nuclear reactors....
Study Demonstrates Climate Change Effects On Forests
Posted by Washington Post: Juliet Eilperin on April 5th, 2011
redOrbit: 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 tomorrow in the journal Global Change Biology, identify earlier spring warming as one of several factors that affect tree reproduction and growth.
They also show summer drought as an important but overlooked risk factor for tree survival,...
Study sees climate change impact on trees
Posted by Washington Post: Juliet Eilperin on April 5th, 2011
United Press International: Tree growth and fecundity -- the ability to produce viable seeds -- are more sensitive to climate change than previously thought, an 18-year U.S. study found.
The study of 27,000 individual trees by National Science Foundation-funded scientists identified earlier spring warming as one of several factors that affect tree reproduction and growth. It also found summer drought was an important risk factor for tree survival, and species in four types of trees -- pine, elm, beech, and magnolia -- are...

ScienceDaily: Mangroves Among the Most Carbon-Rich Forests in the Tropics; Coastal Trees Key to Lowering Greenhouse Gases
Coastal mangrove forests store more carbon than almost any other forest on Earth, according to a study conducted by a team of U.S. Forest Service and university scientists.
Their findings are published online in the journal Nature Geoscience.
A research team from the U.S. Forest Service's Pacific Southwest and Northern research stations, University of Helsinki and the Center for International...
