US wood pellet exports to Europe hit record high
April 24, 2014 08:10 AM - ClickGreen Staff, ClickGreen
Europe's boom in biomass demand has led to a doubling of wood pellet exports from North America in just two years to reach 4.7 million tons in 2013, according to the latest data. North America exported wood pellets valued at over 650 million dollars in 2013, a dramatic increase of more than 250 percent in just two years, according to new research released by the North American Wood Fibre Review. The US South shipped almost three million tons last year, which was almost two-thirds of total export volume from North America, and with no slowdown in sight, North American wood pellet exporting companies keep building new facilities to manufacture pellets for the European market.
Odds of storm waters flooding Manhattan up 20-fold, new study finds

Maximum water levels in New York harbor during major storms have risen by nearly two and a half feet since the mid-1800s, making the chances of water overtopping the Manhattan seawall now at least 20 times greater than they were 170 years ago, according to a new study.
To bee or not to bee

Bumblebees are among the most loved and familiar of garden insects. The sight and sound of them buzzing from flower to flower is a quintessential part of summertime, but sadly these charismatic creatures are now struggling to survive. In our modern world of paved gardens and intensive agriculture our bumblebees find themselves hungry and homeless.
World's first Water Stewardship Standard is released
April 9, 2014 08:07 AM - ClickGreen Staff, ClickGreen
The first international Water Stewardship Standard, a global framework to promote sustainable freshwater use, has been released by the Alliance for Water Stewardship (AWS). The Standard defines globally applicable, consistent criteria for sustainable management and use of the world's limited freshwater resources. "We are excited to see global leaders join us on the journey towards sustainable and equitable water use," said Michael Spencer, Chair of AWS's board and representative of Water Stewardship Australia.

Una prueba de campo ha demostrado por primera vez que los niveles elevados de dióxido de carbono restringen la capacidad de las plantas para transformar los nitratos en proteínas
Nutritional quality of food crops decreases as CO2 levels rise
April 7, 2014 08:02 AM - ClickGreen Staff, ClickGreen
A field test has demonstrated for the first time that elevated levels of carbon dioxide restrict plants' ability to transform nitrate into proteins, indicating that the nutritional quality of food crops is at risk as climate change intensifies.
Wild Bees Improve Farm Revenues by Boosting Crop Yields
April 3, 2014 01:09 PM - Click Green Staff, ClickGreen
Investing in habitat that attracts and supports wild bees in farms is not only an effective approach to helping enhance crop pollination, but it can also pay for itself in four years or less, according to Michigan State University research. The paper, published in the current issue of the Journal of Applied Ecology, gives farmers of pollination-dependent crops tangible results to convert marginal acreage to fields of wildflowers, said Rufus Isaacs, MSU entomologist and co-author of the paper.
NASA study finds Arctic melt is now 15 days longer than 30 years ago

The length of the melt season for Arctic sea ice is growing by several days each decade, and an earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation in some places to melt as much as four feet of the Arctic ice cap’s thickness, according to a new study by National Snow and Ice Data Center (NSIDC) and NASA researchers.

Greenhouse gas emissions from food production may threaten the UN climate target of limiting global warming to 2 degrees Celsius, according to research at Chalmers University of Technology in Sweden.
Antarctic ice study reveals accelerated sea level rise

Six massive glaciers in West Antarctica are moving faster than they did 40 years ago, causing more ice to discharge into the ocean and global sea level to rise, according to new research. The amount of ice draining collectively from those half-dozen glaciers increased by 77 percent from 1973 to 2013, scientists report this month in Geophysical Research Letters, a journal of the American Geophysical Union.
