Global Study of Salmon Shows: 'Sustainable' Food Isn't So Sustainable



Consider improving the food misses the point in the increasingly popular as a result of three years of education systems worldwide salmon production. However, organic production and land use concerns, or simple measures such as "promoting food miles" more research. focus on environmental improvement of production and distribution of the world you can find additional benefits.

Diatoms Reveal Climate Changes


This 500-year period in northern Scandinavia and Sweden, have changed over the flow of air may increase the amount of rainfall in the winter. It appears in the comments. New geography at the University of Stockholm.

Knowledge of these changes is the cause of climate change on our historical inevitability of climate change in how we understand the mechanisms behind the effects of human activities on them.

Ancient High-Altitude Trees Grow Faster as Temperatures Rise


Rapid growth of the post is added to supply high-altitude temperatures in the Pines of the world's oldest tree found in bristlecone 1950, according to new research.

The Pines 3700 years ago, extensive growth over the period 1951-2000 was close to the timberline, and the University of Arizona-led research team reported. Temperature region over the past 50 years has increased, especially in the highlands.

Climate Policy Imperils China, India

BARCELONA, Spain, Nov 5 (Reuters) – China should roughly halve its greenhouse gas emissions by 2050 to keep the world on a safe climate path, the head of the U.S. delegation at U.N. climate talks in Barcelona said on Thursday.

Leading industrialised countries say that the world must halve greenhouse gases by 2050 to avoid the worst effects of climate change, and have committed to lead by cutting their own emissions by 80 percent.

China should cut by about 50 percent, leaving space for poorer countries to grow their economies, Jonathan Pershing told Reuters.

“If you put China in there at a 50 percent reduction, if we’re a bit higher, that gives lesser developed countries a bit lower. If they are in that middle band, plus or minus some percentage, that seems about right.”

If it is to meet the targets on a course to repeat the performance of China’s current energy. 5, the annual plan for the future, he added. “They’re wrong,” he said.

North Atlantic Fish Populations Shifting As Ocean Temperatures Warm


Several types of northwest Atlantic about half the value of these 36 fish stocks. Change the commercials in the 14-year period of some interest. Disappeared from the waters of the United States most Americans, they move far away from the coast by a new study by NOAA scientists.

The results are published in the journal Marine Ecology Progress Series, they change the temperature and the border with Canada, Cape Hatteras, from North Carolina, shows the impact of coastal fisheries.
