IPCC concludes: Renewable energy shift is a must
April 15, 2014 10:34 AM - ENN Editor
Conclusions from the Intergovernmental Panel on Climate Change's are simple: rapid shifts to renewable energy are needed to avert catastrophic global warming. The IPCC's report was produced by 1250 international experts and approved by each major government in the world. The report documented increases in human-caused greenhouse gases, the source of those gases, and their climatic effect. The most significant conclusions resulting from IPPC report are: - Current efforts to reduce greenhouse gases are not enough. - Energy supply is not the only thing driving emission increases. - Big changes will be needed to avoid disaster scenarios.
Bats can help protect rice farms against pests

[KUALA LUMPUR] Bats that prey on a major rice pest in Thailand could save paddy harvests worth millions of dollars and help contribute to better food security, scientists say in a paper published in Biological Conservation recently (March).
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.
2014 ten most endangered rivers
April 10, 2014 12:10 PM - ENN staff
American Rivers yesterday announced its annual list of America's Most Endangered Rivers®, 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 Outdated water management and excessive diversions, compounded by the current drought, have put the San Joaquin River at a breaking point.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.

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.
