Human Life Expectancy Linked to Extinctions
April 16, 2014 04:14 PM - Dominic Rowland, MONGABAY.COM
Since the arrival of Homo sapiens, other species have been going extinct at an unprecedented rate. Most scientists now agree that extinction rates are between 100 and 1000 times greater than before humans existed. Working out what is driving these extinctions is fiendishly complicated, but a new study by scientists from the University of California, Davis and the Nebraska Cooperative Fish and Wildlife Research Unit suggests that human life expectancy may be partly to blame.
Electric car numbers double in one year
April 16, 2014 09:10 AM - Editor, The Ecologist
There are now more than 400,000 electric cars on the world's roads - twice as many as a year ago, and on current trends there will be a million by 2016. Leading the market are the USA, Japan and China - while Europe trails behind. The number of electrically powered automobiles worldwide climbed to just over 400,000 in early 2014. This figure was determined in an analysis conducted by the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW).
Weather throws a curve
April 16, 2014 07:14 AM - Robin Blackstone, ENN
Apparently the intense curve of the jet stream can predict the variability of an entire season and it is part of a 4,000 year pattern. Last winter's curvy jet stream in North America resulted in mild western temperatures and harsher cold temperatures in the east. University of Utah researchers reveal that a similar pattern became more pronounced 4,000 years ago, suggesting that it may worsen as Earth's climate warms.
Moth Study Reveals Hidden Climate Change Impacts
April 15, 2014 01:38 PM - Allison Winter, ENN
More and more studies are reporting climate change as the main culprit for not only species adaptation, but also for changes in population size. But a new study shows that population increases or decreases cannot only be attributed to increasingly warmer weather and that multiple factors play a role when it comes to species population.
Electricity Prices Fall In Europe As German Renewable Energy Output Increases
April 15, 2014 01:18 PM - Gina-Marie Cheeseman, Triple Pundit
For the fifth consecutive month, electricity prices in countries neighboring Germany have decreased, recently released Platts data reveals, due in large part to increased solar and wind generation in Germany.
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.
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.
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.
Largest Cleanup in EPA History Proposed
April 14, 2014 08:14 AM - ENN Staff
In an historic action that will protect people's health and the environment, and benefit riverfront communities, the U.S. Environmental Protection Agency proposed a plan to remove 4.3 million cubic yards of highly contaminated sediment from the lower eight miles of the Passaic River in New Jersey. The sediment in the Passaic River is severely contaminated with dioxin, polychlorinated biphenyls (PCBs), heavy metals, pesticides and other contaminants from more than a century of industrial activity. Ninety percent of the volume of contaminated sediments in the lower Passaic are in the lower eight miles of the river.
