Polar Ice Update, Record lows in the Arctic, Record Highs in the Antarctic
October 4, 2012 06:53 AM - ScienceDaily
This September, sea ice covering the Arctic Ocean fell to the lowest extent in the satellite record, which began in 1979. Satellite data analyzed by NSIDC scientists showed that the sea ice cover reached its lowest extent on September 16. Sea ice extent averaged for the month of September was also the lowest in the satellite record. The near-record ice melt occurred without the unusual weather conditions that contributed to the extreme melt of 2007. In 2007, winds and weather patterns helped melt large expanses of ice. "Atmospheric and oceanic conditions were not as conducive to ice loss this year, but the melt still reached a new record low," said NSIDC scientist Walt Meier. "This probably reflects loss of multi-year ice in the Arctic, as well as other factors that are making the ice more vulnerable." Multi-year ice is ice that has survived more than one melt season and is thicker than first-year ice.
Inuit Face Tensions with Outside World as their environment melts away
October 2, 2012 06:35 AM - Ed Struzik, Yale Environment360
With Arctic summer sea ice rapidly disappearing, the native Inuit of Canada are encountering not only unsettling changes in their subsistence way of life, but also a growing number of outsiders who will further transform their once-isolated homeland. Sakiasiq Qanaq has seen a lot of changes on the north coast of Baffin Island in recent years as the retreat of summer sea ice has continued unabated. But the Inuit hunter has never seen anything quite like this year, when sea ice loss in the Arctic hit a record low. First, the community's spring narwhal hunt, which usually yields roughly 60 of the tusked whales, produced only three. The sea ice was so thin that the Inuit couldn’t safely stand on it and shoot the narwhal as they migrated into Arctic Bay from Greenland through channels in the ice. Then an unprecedented number of killer whales, or orcas — rarely seen in heavy ice — showed up in the largely ice-free water, with Inuit hunters in nearby Pond Inlet observing three pods of orcas that reportedly killed some of the narwhals and scared off the others.
Norwegian Arctic Summers Warmest in 1,800 Years
September 30, 2012 10:13 AM - Yale Environment360
Summer temperatures on the Norwegian archipelago of Svalbard in the High Arctic are now higher than during any time over the last 1,800 years, including a period of higher temperatures in the northern hemisphere known as the Medieval Warm Period, according to a new study. In an analysis of algae buried in deep lake sediments, a team of scientists calculated that summer temperatures in Svalbard since 1987 have been 2 to 2.5 degrees Celsius (3.6 to 4.5 degrees F) warmer than during the Medieval Warm Period, which lasted from roughly 950 to 1250 AD. Scientists say this year's record declines in Arctic sea ice extent and volume are powerful evidence that the giant cap of ice at the top of the planet is on a trajectory to largely disappear in summer within a decade or two, with profound global consequences.
Smokey Robinson Launches Smoke Alarm site to Fight Water-Borne Diseases
September 29, 2012 09:24 AM - RP Siegel, Triple Pundit
Legendary R&B singer and songwriter Smokey Robinson has launched a social media site called Smoke Alarm as a way of getting the word out on important issues of the day. What makes Smoke Alarm so powerful is the number of celebrity participants he has on board, including Elton John, Hillary Duff, Daryl Hall, Eva Longoria and James Franco, among others who pass these messages along to their Facebook fans and Twitter followers. The site currently has over 44 million subscribers. The first issue that Smokey is tackling is a great one, the challenge of providing clean drinking water to millions of people around the world who do not have it.
Experts Hope to Establish Congressional Weather Commission
September 28, 2012 02:55 PM - Allison Winter, ENN
From energy freedom to ocean policy focusing on commerce, research, and defense, Congress has appointed a variety of environmental-based commissions in the past two decades. However, one issue that has yet to be addressed is weather—that is until now. Experts are asking Congress to create the first US Weather Commission. This commission would offer guidance of their weather expertise to policy makers who would then be able to make more efficient decisions when it comes to weather-related issues.
The Kathmandu Valley Needs Help!
September 27, 2012 05:56 AM - Joseph Mayton, The Ecologist
The once bustling Bagmati river has become the focal point of Nepal's struggle to bring modernity to this once isolated region. And the environment is struggling to survive, writes Joseph Mayton. It is "clean-up" day on Nepal’s major river, the Bagmati. Uniformed military personnel troll the banks of the river, picking up plastic bags and rubbish that has found its way onto the sides what once was the main thoroughfare for the Kathmandu Valley. Turning, with pieces in his hand, one officer lightly tosses the rubbish into the already polluted water.
Update - High Altitude Wind Energy Potential
September 26, 2012 05:35 AM - Dave Levitan, Yale Environment360
A host of start-up companies are exploring ways to harness the enormous amount of wind energy flowing around the earth, especially at high altitudes. But as these innovators are discovering, the engineering and regulatory challenges of what is known as airborne wind power are daunting. The wind turbines that increasingly dot the landscape peak at around 300 feet above ground, with the massive blades spinning a bit higher. The wind, however, does not peak at 300 feet. Winds are faster and more consistent the higher one climbs, maxing out in the jet streams at five miles and above.
New study analyzes challenges with international water-related projects
September 25, 2012 09:35 AM - Allison Winter, ENN
Large-scale water-related projects are a model global environmental issue. From dams controlling and rerouting water flow to providing access to clean drinking water and monitoring the nutrient quality of water resources, local, national, and international players often have to work together to manage these water resources. As trans-boundary issues are bound to arise, efforts need to be addressed in order to manage concerns. A new study of nearly 200 major international water-related projects over the past 20 years has identified existing and emerging challenges and how science can offer solutions.
23 Nuclear Plants in Tsunami Risk Zones, Study Finds
September 24, 2012 08:53 AM - Live Science Staff, Live Science
In March 2011, a devastating earthquake and tsunami set off a partial meltdown at the Fukushima nuclear plant on Japan's coast. A recent study led by European researchers found Fukushima is not alone, as 22 other plants around the world may be similarly susceptible to destructive tsunami waves, with most of them in east and southeast regions of Asia.
The Problem with Tree Plantations
September 22, 2012 08:08 AM - Isaac Rojas, MONGABAY.COM
Today, September 21, is the "International Day of Struggle against Monoculture Tree Plantations", an annual event organized by a coalition of social and environmental groups. Here, Isaac Rojas, a Costa Rican who is Friends of the Earth International coordinator of its Forest and Biodiversity Program, expresses his view point on industrial plantations. Public environmental awareness has come a long way since September 1962, when Rachel Carson's 'Silent Spring' was published, stimulating the birth of the environmental movement. This movement may be fifty years old, but nowadays you can feel 'green' by helping destroy forests instead of protecting them, for instance by clicking online a 'plant a tree' button on a seemingly well-meaning website.
