Climate Change: We have met the enemy and they are us
April 14, 2014 09:35 AM - ENN Editor

According to McGill University physics professor Shaun Lovejoy, we have no one to blame but ourselves for global warming in the industrial era. Lovejoy and his research team have just completed an analysis of temperature data covering more than 500 years. This study all but rules out the possibility that global warming is just a natural fluctuation in the earth's climate.

April 10, 2014 12:10 PM - ENN staff

American Rivers yesterday announced its annual list of America's Most Endangered RiversĀ®, naming California's San Joaquin River the Most Endangered River in the country. Outdated water management and excessive diversions, compounded by the current drought, have put the San Joaquin River at a breaking point.

At more than 23,000 feet, why don't bar-headed geese get hypoxic?
April 9, 2014 10:04 AM - ENN Staff

The bar-headed goose migratory path takes it over the Himalayan Mountains each year between China and Mongolia to their Indian breeding grounds. This flight path puts them at 23,917 feet above sea level. University of Exeter led study followed these birds to gain insight into their ability to survive these extreme altitudes in hopes that their findings might have future implications for low oxygen medical conditions in humans.

Why Are Scientists Genetically Modifying Trees?
April 7, 2014 10:41 AM - Kevin Mathews, Care2

The Lorax may speak for the trees, but even he might want to stop to listen to researchers' new plans to genetically alter trees. What may outwardly seem like disconcerting news just might change how paper is made for the better. The engineered trees would allow manufacturers to create paper significantly easier. Moreover, it's not just the paper industry that benefits from this change — the effects would be advantageous to the entire planet.

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.

Badger Culls in England Will Not Expand
April 6, 2014 09:32 AM - Judy Molland, Care2

This is great news for most of the badger population of England. Plans to roll out the controversial badger cull pilots nationwide across England have been dropped by the Environment Secretary, Owen Paterson, after an independent report found the shoots were not effective or humane. The pilot programs were run in Gloucestershire and Somerset in an effort to stop the spread of Bovine Tuberculosis among cattle, and the environment department's original plan was to announce up to 10 new cull areas each year.

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.

Filipino vulnerability
April 3, 2014 11:24 AM - By Esperanza Garcia, Worldwatch Institute

Climate change has been a constant reality for many Filipinos, with impacts ranging from extreme weather events to periodic droughts and food scarcity. The most affected populations are coastal residents and rural communities that lack proper disaster preparedness.

American's energy usage jumps in 2013
April 2, 2014 01:08 PM - ENN Staff

Despite many individual efforts to decrease energy usage for 2013 increased by 2.3 Quadrillion thermal units over the previous year. These statistics have been monitored and presented by the Lawrence Livermore National Laboratory (LLNL) in the most recent energy flow charts measuring renewable, fossil and even nuclear energy.

IPCC warns over greater risk to food and water security
April 2, 2014 10:38 AM - F.Fiondella/IRI/CCAFS, SciDevNet

[NEW DELHI] The climate change-related risks from extreme events such as floods and heat waves will rise further with global warming, aggravating food and water insecurity, especially for some of the poorest communities, says the second instalment of the latest UN Intergovernmental Panel on Climate Change (IPCC) report.
