Challenges and a call for Conservation Cooperation in the Arab world
March 8, 2014 08:31 AM - Mark Henley, SciDevNet
The Arab region's best chance of facing the challenges of food insecurity, water scarcity and natural disasters lies in collaborating on environmental preservation, a study says. The study, published in The Lancet (20 January), argues that current academic discussions about health, population and development in the Arab region fail to convey the true level of urgency.
Arctic sea ice melting one warm river at a time
March 7, 2014 09:32 AM - Maria-Jose Vinas, NASA Earth Science News Team
A new NASA study finds that warmer than normal waters from rivers draining into the Arctic Ocean each summer are eating away at the sea ice in the Arctic Ocean. Led by Son Nghiem of NASA's Jet Propulsion Laboratory in Pasadena, Calif., the research team used satellite data to measure the surface temperature of the waters discharging from Canada's McKenzie River into the Beaufort Sea during the summer of 2012 and noticed surface waters being warmed suddenly due to the sudden influx of warm river water This warmed the surface layers of the ocean, which in turn increased the melting of sea ice.
EPA Sets Cleaner Fuel and Car Standards
March 4, 2014 09:20 AM - ENN Staff
Yesterday the U.S. Environmental Protection Agency (EPA) finalized emission standards for cars and gasoline that will significantly reduce harmful pollution and in turn prevent thousands of premature deaths and illnesses related to respiratory ailments. Based on extensive input from the public and a broad range of stakeholders, including public health groups, auto manufacturers, refiners, and states, the standards will also enable efficiency improvements in the cars and trucks we drive.
Amazon Trees Diverse in Chemicals
March 4, 2014 08:17 AM - Jeremy Hance, MONGABAY.COM
In the Western Amazon—arguably the world's most biodiverse region—scientists have found that not only is the forest super-rich in species, but also in chemicals. Climbing into the canopy of thousands of trees across 19 different forests in the region—from the lowland Amazon to high Andean cloud forests—the researchers sampled chemical signatures from canopy leaves and were surprised by the levels of diversity uncovered.
COLLEGIATE CORNER: The faults of fracking
March 3, 2014 11:41 AM - Reid Short, Class of 2015, Wakefield High School, Arlington, VA
Hydraulic Fracturing is a process that sends pressurized liquid down to a target depth to fracture rock and draws out liquids, such as natural gas. This process is used to retrieve the gas from rock formations beneath the earth that were previously thought to be unsuitable for gas production (Helman) (Rao). Fracking is now being implemented all over the world. Many countries have turned to this method of extracting gas to lower fuel costs and balance their trade deficits, but these countries, including the United States, are allowing fracking to cause major damage to the environment. The water pollution, and air pollution that are caused by fracking, and the law exemptions it has, are inexcusable because of the damage and danger they cause to the environment.
Doubling the flood loss projections in Europe
March 3, 2014 10:36 AM - ENN Staff
As development and climate change continue, losses from extreme floods throughout the world skyrocket. Researchers from the International Institute for Applied Systems Analysis (IIASA), in Austria have projected that the losses in Europe could more than double by 2050. In the new study which is published in the journal Nature Climate Change, they contend that understanding the risk posed by large-scale floods is of growing importance and will be key for managing climate adaptation.
80% of Europeans want a low carbon economy to help tackle climate change
March 3, 2014 08:17 AM - ClickGreen Staff, ClickGreen
Four out of five people in the European Union recognize that fighting climate change and using energy more efficiently can boost the economy and employment, according to a special Eurobarometer opinion poll on climate change published today.
Is Global Warming responsible for weather extremes?
March 1, 2014 07:59 AM - Fred Pearce, Yale Environment360
Scientists are trying to understand if the unusual weather in the Northern Hemisphere this winter — from record heat in Alaska to unprecedented flooding in Britain — is linked to climate change. One thing seems clear: Shifts in the jet stream play a key role and could become even more disruptive as the world warms. This winter’s weather has been weird across much of the Northern Hemisphere. Record storms in Europe; record drought in California; record heat in parts of the Arctic, including Alaska and parts of Scandinavia; but record freezes too, as polar air blew south over Canada and the U.S., causing near-record ice cover on the Great Lakes, sending the mercury as low as minus 50 degrees Celsius in Minnesota, and bringing sharp chills to Texas.
And the spotted seal said, "Say whaaaat?"
February 28, 2014 03:26 PM - Tim Stephens, University of California – Santa Cruz
Two spotted seals orphaned as pups in the Arctic are now thriving at UC Santa Cruz's Long Marine Laboratory, giving scientists a rare opportunity to learn about how these seals perceive their environment. In a comprehensive study of the hearing abilities of spotted seals, UCSC researchers found that the seals have remarkably sensitive hearing in both air and water.
Melting summer ice in Antarctica
February 28, 2014 01:53 PM - , ClickGreen
Antarctica's Ross Sea is one of the few Polar Regions where summer sea-ice coverage has increased during the last few decades, bucking a global trend of drastic declines in summer sea ice across the Arctic Ocean and in two adjacent embayments of the Southern Ocean around Antarctica. But now, a modeling study led by Professor Walker Smith of the Virginia Institute of Marine Science suggests that the Ross Sea's recent observed increase in summer sea-ice cover is likely short-lived, with the area projected to lose more than half its summer sea ice by 2050 and more than three quarters by 2100.
