Survey Ranks U.S. as Biggest Climate Change Denier
August 5, 2014 08:27 AM - RP Siegel, Triple Pundit

This may confirm suspicions that many of us have already had. Besides leading the world in consumer debt and military spending, the U.S. can now add climate denial to that list. That is, according to a Global Trends survey by the U.K.-based market research firm Ipsos MORI. The study polled 16,000 people in 20 leading countries on eight different topics, including the environment. Not only was the U.S. last, but it was last by a considerable margin.

Atlantic Ocean warming linked to Pacific trade winds
August 4, 2014 07:38 AM - Staff ClickGreen, ClickGreen

New research has found rapid warming of the Atlantic Ocean, likely caused by global warming, has turbocharged Pacific Equatorial trade winds. Currently the winds are at a level never before seen on observed records, which extend back to the 1860s. The increase in these winds has caused eastern tropical Pacific cooling, amplified the Californian drought, accelerated sea level rise three times faster than the global average in the Western Pacific and has slowed the rise of global average surface temperatures since 2001.

Study predicts climate change and pollution will combine to impact food production
August 2, 2014 09:50 AM - EcoRI News staff

Many studies have shown the potential for global climate change to cut food supplies. But these studies have, for the most part, ignored the interactions between increasing temperature and air pollution -- specifically ozone pollution, which is known to damage crops. A new study involving researchers at MIT shows that these interactions can be quite significant, suggesting that policymakers need to take both warming and air pollution into account in addressing food security.

Defending against sea level rise could make the problem worse
August 1, 2014 09:12 AM - Harriet Jarlett, Planet Earth Online

A combination of coastal defences and rising sea levels could change typical UK tidal ranges, potentially leading to a higher risk of flooding, say scientists. The researchers wanted to find out how tides around the UK might respond to changes in sea level over the next century depending on the level of coastal defences in place.

CO2 decrease cause of Antarctic ice sheet growth in ice age
July 31, 2014 06:15 AM - University of New Hampshire via ScienceDaily

Climate modelers from the University of New Hampshire have shown that the most likely explanation for the initiation of Antarctic glaciation during a major climate shift 34 million years ago was decreased carbon dioxide (CO2) levels. The finding counters a 40-year-old theory suggesting massive rearrangements of Earth's continents caused global cooling and the abrupt formation of the Antarctic ice sheet. It will provide scientists insight into the climate change implications of current rising global CO2 levels. In a paper published today in Nature, Matthew Huber of the UNH Institute for the Study of Earth, Oceans, and Space and department of Earth sciences provides evidence that the long-held, prevailing theory known as "Southern Ocean gateway opening" is not the best explanation for the climate shift that occurred during the Eocene-Oligocene transition when Earth's polar regions were ice-free.

Catching Waves in the Arctic
July 30, 2014 08:52 AM - University of Washington

As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water that is predicted to extend across the whole Arctic Ocean before the middle of this century. Storms thus have the potential to create Arctic swell — huge waves that could add a new and unpredictable element to the region. A University of Washington researcher made the first study of waves in the middle of the Arctic Ocean, and detected house-sized waves during a September 2012 storm. The results were recently published in Geophysical Research Letters.

General Motors, OnStar, EV's and the Smart Grid
July 29, 2014 01:09 PM - Editor, Justmeans

General Motors is bringing its OnStar-enabled Smart Grid solutions, to one of the largest electric vehicle collaborations to take place within the industry. Eight global automakers, including GM, and 15 electric utilities are working with the Electric Power Research Institute to develop and implement a standardized Smart Grid integration platform. "One thing that’s missing from most Smart Grid programs is a sense of collaboration," said Tim Nixon, chief technology officer, Global Connected Consumer, GM. "Companies will showcase a meaningful solution, but without widespread acceptance in the industry, its usability is limited. That's what makes this partnership unique."

Ozone + Rising Temperatures = Problems for Food Security
July 28, 2014 02:37 PM - Editor, ENN

A new study shows that interactions between increasing temperature and air pollution can be quite significant when it comes to addressing food security. Conducted in part by researchers at MIT, a study looked in detail at global production of four leading food crops — rice, wheat, corn, and soy. It predicts that effects will vary considerably from region to region, and that some of the crops are much more strongly affected by one or the other of the factors

The important role of community forests
July 25, 2014 07:49 AM - Yale Environment360

Expanding and strengthening the community forest rights of indigenous groups and rural residents can make a major contribution to sequestering carbon and reducing CO2 emissions from deforestation, according to a new report. The World Resources Institute (WRI) and the Rights and Resources Initiative said that indigenous people and rural inhabitants in Latin America, Africa, and Asia have government-recognized rights to forests containing nearly 38 billion tons of carbon, equal to 29 times the annual emissions of all the world’s passenger vehicles. By enforcing community rights to those forests, the study said, governments can play a major role in tackling climate change. In the Brazilian Amazon, for example, deforestation rates are 11 times lower in community forests than in forests outside those areas. In areas where community forest rights are ignored, deforestation rates often soar. The report made five major recommendations, from better enforcement of community forest zones to compensating communities for the climate and other benefits their forests provide.

Groundwater depletion and western US water supply
July 24, 2014 04:34 PM - NASA and UC Irvine

A new study by NASA and University of California, Irvine, scientists finds more than 75 percent of the water loss in the drought-stricken Colorado River Basin since late 2004 came from underground resources. The extent of groundwater loss may pose a greater threat to the water supply of the western United States than previously thought. This study is the first to quantify the amount that groundwater contributes to the water needs of western states. According to the U.S. Bureau of Reclamation, the federal water management agency, the basin has been suffering from prolonged, severe drought since 2000 and has experienced the driest 14-year period in the last hundred years.
