Egyptian art sheds light on changing ecosystem
September 19, 2014 07:47 AM - Bristol University

Depictions of animals in ancient Egyptian artefacts have helped scientists assemble a detailed record of the large mammals that lived in the Nile Valley over the past 6,000 years. A new analysis of this record shows that species extinctions, probably caused by a drying climate and growing human population in the region, have made the ecosystem progressively less stable. The study, published in Proceedings of the National Academy of Sciences (PNAS), found that local extinctions of mammal species led to a steady decline in the stability of the animal communities in the Nile Valley.

Fall foliage may be delayed, but will last longer

The fall foliage season that prompts millions of Americans to undertake jaunts into the countryside each year could come much later and possibly last a little longer within a century, according to new research. Climate change could postpone fall leaf peeping in some areas of the United States as summer temperatures linger later into the year, Princeton University researchers report in the journal Global Ecology and Biogeography.

Climate March and Summit
September 17, 2014 09:08 AM - Editor, The Ecologist

This Sunday 21st September hundreds of thousands of people have pledged to march in New York, London, Amsterdam and many other cities around the world to demand climate justice, standing with climate and dirty energy-affected communities worldwide. They are hoping to influence world leaders gathering in New York for their one-day Climate Summit taking place on 23rd September to exceed the poor expectations vested in them.

Electric vehicles getting even "Greener"
September 16, 2014 03:01 PM - Union of Concerned Scientists

Sixty percent of Americans now live in regions where electric vehicles (EVs) produce fewer heat-trapping global warming emissions per mile than the most efficient hybrids, according to an updated analysis from the Union of Concerned Scientists (UCS). In 2012, that number was just 45 percent. "Electric vehicles are doing more and more to fulfill their technological promise," said Don Anair, research director for UCS's Clean Vehicles Program. "If we want to reduce transportation pollution and oil use, a big part of the answer is to be like Bob Dylan and go electric."

Northern Lights Dazzle Skies Tonight

If you live in one of the visible areas on this map, you may be in for a treat tonight! According to AccuWeather.com, the solar flares of the Northern Lights are ranked as an X-class tonight, the highest class for a solar flare which may make the Northern Lights display as far south as Maryland on the East Coast, and as far down as Nebraska, further west.

California Drought: Why Farmers Must Adapt
September 12, 2014 08:40 AM - Gina-Marie Cheeseman, Triple Pundit

The entire state of California is in a drought. A big part of the state, including the fertile Central Valley, is experiencing the worst category of drought, exceptional. California supplies much of the fruits, vegetables and nuts the nation eats. In inland areas such as the Central Valley, as well as the combined Sacramento and San Joaquin valleys, agriculture truly rules.

How is a warming climate impacting coral reefs?
September 10, 2014 07:34 AM - Roger Greenway, ENN

How is a warming climate impacting life in the oceans? Fish can move to cooler areas, but coral reefs are anchored in place. Late-summer water temperatures near the Florida Keys were warmer by nearly 2 degrees Fahrenheit in the last several decades compared to a century earlier, according to a new study by the U.S. Geological Survey. Researchers indicate that the warmer water temperatures are stressing corals and increasing the number of bleaching events, where corals become white resulting from a loss of their symbiotic algae. The corals can starve to death if the condition is prolonged.

Greenhouse gases hit new record
September 9, 2014 11:07 AM - Alex Kirby, The Ecologist

The World Meteorological Organization (WMO) has reported that the amounts of atmospheric greenhouse gases reached a new high in 2013, driven by rapidly rising levels of carbon dioxide. The news is consistent with trends in fossil fuel consumption. But what comes as more of a surprise is the WMO's revelation that the current rate of ocean acidification, which greenhouse gases (GHGs) help to cause, appears unprecedented in at least the last 300 million years.

Block Island wind farm gets final approvals
September 5, 2014 06:00 PM - ecoRI News staff

Deepwater Wind has received the final federal approval needed to build the Block Island Wind Farm — a project that remains on-track to be the nation’s first offshore wind farm. The project’s lead federal permitting agency, the Army Corps of Engineers, granted its approval Sept. 5. With the Corps’ permit, the Block Island Wind Farm has now been completely reviewed, and approved, by nine state and federal agencies: Army Corps of Engineers, Federal Aviation Administration, U.S. Fish & Wildlife Service, National Oceanic and Atmospheric Administration, Environmental Protection Agency, Coast Guard, Rhode Island Coastal Resources Management Council, Rhode Island Department of Environmental Management and the Rhode Island State Historic Preservation Office.

Ozone pollution in India kills crops that could feed starving population
September 4, 2014 03:23 PM - ClickGreen Staff, ClickGreen

In one year, India's ozone pollution damaged millions of tons of the country's major crops, causing losses of more than a billion dollars and destroying enough food to feed tens of millions of people living below the poverty line. These are findings of a new study that looked at the agricultural effects in 2005 of high concentrations of ground-level ozone, a plant-damaging pollutant formed by emissions from vehicles, cooking stoves and other sources. Able to acquire accurate crop production data for 2005, the study's authors chose it as a year representative of the effects of ozone damage over the first decade of the 21st century.
