The Andes' pulsating rise
April 22, 2014 03:10 PM - Robin Blackstone, ENN
New research by Carmala Garzione, Earth and Environmental Sciences professor from the University of Rochester suggests that the Antiplano plateau in the central Andes Mountains along with the entire mountain range likely arose in a series of periodic rapid pulses instead of a more continuous gradual surface uplift. According to Garzione, "In geologic terms, rapid means rising one kilometer or more over several millions of years, which is very impressive."
The Evolution of Earth Day
April 22, 2014 10:29 AM - Allison Winter, ENN
Each year April 22nd, marks the anniversary of what many consider the birth of the environmental movement in 1970. Not only did this movement help pass landmark legislation like the Clean Air Act, Clean Water Act, and Endangered Species Act but it has also engaged more than 1 billion people who now participate in Earth Day activities each year.
Narcotics + Deforestation = Narco-Deforestation
April 21, 2014 02:12 PM - Robin Blackstone, ENN
Narco-Deforestation, a newly coined term for the destruction of sensitive forest ecologies in Central and South America has been identified as a greater threat to the South and Central American forests than other previously identified concerns such as legal logging and development. The drug traffickers are creating new autoroutes and airplane strips for greater access to and through the forests and jungles of the Central and South America. These new routes make it easier to transport drugs from Mexico to South America and vice-versa.
That sinking feeling on the Mississippi Delta
April 21, 2014 09:49 AM - Robin Blackstone, ENN
Every engineering control has its drawbacks. As communities upstream of the Mississippi Delta continue to emplace dams and other flood control measures to prevent community flooding, less sediment is pulled from the lands upstream. Flood control measures have eliminated about half of the annual supply of marshland sediment to the Mississippi Delta. The existing soils continue to compact and sink without sediment replenishment. But researchers have found that the river’s supply of sand, the key ingredient used by engineers for rebuilding, will remain constant for many centuries.
New data on what Greenland was like almost 3 million years ago

Glaciers and ice sheets are commonly thought to work like a belt sander. As they move over the land they scrape off everything — vegetation, soil and even the top layer of bedrock. So a team of university scientists and a NASA colleague were greatly surprised to discover an ancient tundra landscape preserved under the Greenland Ice Sheet, below two miles of ice. "We found organic soil that has been frozen to the bottom of the ice sheet for 2.7 million years," said University of Vermont geologist and lead author Paul Bierman. The finding provides strong evidence that the Greenland Ice Sheet has persisted much longer than previously known, enduring through many past periods of global warming.
The Atlantic Cup looks to raise awareness on Rhode Island’s increasingly polluted shorelines
April 18, 2014 11:32 AM - Guest Contributor, Jeff Pomeroy
The 2014 Atlantic Cup presented by 11th Hour Racing, now entering its fourth year as the United States premiere class 40 yacht race, continues to lead the way in clean sailing and increasing ecologically awareness in the sailing community. In 2012, the Atlantic Cup became the first carbon-neutral sailing race in the country by offsetting an estimated 23,030 pounds (10.45 metric tons) of CO2 from entering the atmosphere. Last year, in partnership with 11th Hour Racing and Green Mountain Energy Company, the Atlantic Cup was chosen as the first event to meet all the requirements to earn Sailors for the Sea Clean Regatta Platinum Level Status. The Atlantic Cup will once again maintain its commitment to being the most environmentally responsible sailing race in the U.S. by using biodiesel hydro generators, solar panels and fuel cells to limit the use of fuel during competition, recycling waste, and becoming a plastic water bottle free event.
Greenland was green
April 18, 2014 08:55 AM - Robin Blackstone, ENN
Greenland the second largest body of ice on Earth was actually green at one point in history. Researchers, including a scientist from Lawrence Livermore National Laboratory, have unearthed cryogenically frozen ancient dirt previously buried under nearly two miles of ice.
Scenario development yields environmental success story
April 17, 2014 03:37 PM - Robin Blackstone, ENN
With so much scenario modeling currently available, we are able to better predict our future and anticipate the outcomes of various habits and activities. While invaluable in the area of prediction, how has that information transformed our environmental status? Is our environmental future optimistic or dismal? Will we be able to celebrate Earth Day in the future knowing that we have responded appropriately to the bleak prophecies?
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.
