Egyptian art sheds light on changing ecosystem
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. >> Read the Full Article
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. >> Read the Full Article
Burlington, Vermont - Now 100% Powered by Renewable Energy
Burlington, Vermont, already considered to be one of the United States's most environmentally progressive cities, has added another line to its impressive green resume. Just recently, the city finalized its transition to relying 100% on renewable resources for its energy. Burlington is Vermont's large city, though that in itself is no big feat â€“ the city has a population of just 42,000. Then again, very few communities of even this size have managed to disassociate themselves from fossil fuels. In order to adequately tackle climate change, cities â€“ big and small â€“ need to prioritize finding and utilizing alternative energy solutions. Burlington had expressed a desire to commit to 100% renewable energy for more than a decade, but it became a real possibility when analysts discovered that it was not only a smart environmental choice, but financially viable, too. In the long run, both the city and residents will not be paying more for clean energy than they were when buying fossil fuels. >> Read the Full Article
Climate March and Summit
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. >> Read the Full Article
Electric vehicles getting even "Greener"
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." >> Read the Full Article
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. >> Read the Full Article
California Drought: Why Farmers Must Adapt
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. >> Read the Full Article
Petrol vs. Diesel
Climate change has made us question the things that we do, from buying food and using energy to riding planes and driving cars. One of the top questions surrounding climate change is this: Which fuel type is more environmentally friendly, petrol or diesel? Common knowledge would make us reply "diesel" right away, as engines running on diesel emit less carbon dioxide or CO2, and less CO2 is better to decrease the amount of greenhouse gases in the atmosphere. However, being eco-friendly isn't as simple as emitting less CO2. Diesel-powered vehicles may emit 20% less CO2 per kilometre travelled, but they may be more harmful for local pollution due to the tiny particles that are released by diesel engines into the atmosphere. The question really isn't which fuel or engine type is more environmentally friendly, as no form of engine that uses fossil fuels will ever become good for the environment. Rather, we should look at which has the capacity to inflict the least amount of damage to the environment. >> Read the Full Article
How is a warming climate impacting coral reefs?
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. >> Read the Full Article
Greenhouse gases hit new record
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. >> Read the Full Article
