Eenvironmental risk assessment of sub-seabed carbon dioxide storage

Fri, 2015-05-15 08:33
A research project of carbon dioxide in the offshore sea bed is often discussed as a means to reduce further the increase of carbon dioxide to the atmosphere. The project has developed recommendations for the selection and monitoring of submarine storage sites as well as an approach to a sound environmental risk assessment. 27 partner institutions from nine European countries cooperated in the project. The outcome helps to adjust regulations, and to operate sub-seabed carbon dioxide storage sites more safely.

John Flanagan Trips Over a Climate Issue

The new majority leader of the State Senate sent environmentalists to Twitter in alarm with his comments on climate change.

Earthquakes reveal deep secrets beneath East Asia

Thu, 2015-05-14 15:28
A new supercomputer model combined earthquake data to create 3-D tomographic images to depths of 900 km, or 560 miles below East Asia. Notable features found include a high velocity structure beneath Tibetan Plateau; and a deep mantle upwelling under Hangai dome in Mongolia.This research could help find hidden hydrocarbon resources and explore deep structures elsewhere.

As carbon emissions climb, so too has Earth's capacity to remove CO2 from atmosphere

Thu, 2015-05-14 14:30
New research confirms that as carbon emissions continue to climb, so too has the Earth's capacity to absorb carbon dioxide from the atmosphere.

Climate scientists find warming in higher atmosphere: Elusive tropospheric hot spot located

Thu, 2015-05-14 09:57
Updated data and better analysis methods have found clear indications of warming in the upper troposphere and a 10 percent increase in winds over the Southern Ocean. The inability to detect this hotspot previously has been used by those who doubt human-made global warming to suggest climate change is not occurring as a result of increasing carbon dioxide emissions.

How rivers regulate global carbon cycle

Wed, 2015-05-13 13:26
River transport of carbon to the ocean is not on a scale that will solve our carbon dioxide problem, but we haven't known how much carbon the world's rivers routinely flush into the ocean, until now. Scientists calculated the first direct estimate of how much and in what form organic carbon is exported by rivers. The estimate will help modelers predict how this export may shift as Earth's climate changes.

Historical land use an important factor for carbon cycling in northern lakes

Wed, 2015-05-13 12:50
The historical past is important when we seek to understand environmental conditions as they are today and predict how these might change in the future, according to researchers whose analyses of lake-sediment records show how lake-water carbon concentrations have varied depending on long-term natural dynamics over thousands of years, but also in response to human impacts over the past several hundred years.

Atmosphere: Finding the missing particles

Wed, 2015-05-13 08:28
For the past 20 years, a large portion of the particles measured in the atmosphere were missing from models. At best, models were able to explain one-tenth of the carbon-rich secondary organic aerosols measured in the air. The problem turned out to be a series of fundamental assumptions used in the models due to a lack of experimental data. All of the assumptions have now been proven false.

Alaska’s Tricky Intersection of Obama’s Energy and Climate Legacies

President Obama’s move to open up Arctic waters to oil and gas drilling as he pursues an ambitious plan to fight climate change illustrates the tensions in his environmental agenda.

Obama’s Catastrophic Climate-Change Denial

The decision to allow Shell to drill for oil in Arctic waters defies warnings that we should leave carbon in the ground.

New study assesses risks of extreme weather to North Texas roads, runways

Tue, 2015-05-12 09:08
A new study explains how climate change and extreme weather will significantly disrupt infrastructure across the Dallas-Fort Worth region by the end of the 21st century. The assessment found the risks to transportation infrastructure from storms are more likely to happen during the spring season. Researchers found a higher likelihood of heat-related risks for infrastructure, particularly during the summer season.

Carbon emissions from peatlands may be less than expected

Mon, 2015-05-11 13:49
Researchers have discovered a dual mechanism that slows peat decay and may help reduce carbon dioxide emissions from peatlands during times of drought. The discovery might be used to reduce the risk that increased drought and global warming will change Earth's peatlands from carbon sinks into carbon sources, as many scientists have feared.

Research aims to restore riparian corridors and an iconic tree

Mon, 2015-05-11 13:49
Beginning on May 11, Forest Service scientists will plant different combinations of tree and shrub species in four riparian areas on the Finger Lakes National Forest in New York and monitor the success of these different treatments for improving carbon and nitrogen ratios in the soil as well as plant, insect and wildlife biodiversity. Another purpose of the research is to evaluate whether degraded stream corridors are suitable habitats for reintroduction of a forest icon, the American elm.

Solving corrosive ocean mystery reveals future climate

Mon, 2015-05-11 12:54
Around 55 million years ago, an abrupt global warming event triggered a highly corrosive deep-water current through the North Atlantic Ocean. The current's origin puzzled scientists for a decade, but an international team of researchers has now discovered how it formed and the findings may have implications for the carbon dioxide emission sensitivity of today's climate.

Influence of increased atmospheric carbon dioxide concentration on European trees

Mon, 2015-05-11 11:23
Increased atmospheric carbon dioxide concentrations have already caused large-scale physiological responses of European forests. In particular, the efficiency of water-use of trees, which is coupled to the uptake of carbon dioxide during photosynthesis of leaves and needles has changed significantly. According to the study of a large, interdisciplinary team of researchers, European broadleaf and coniferous trees have increased their water-use efficiency since the beginning of the 20th century by 14% and 22%, respectively.

New method developed to assess cancer risk of pollutants

Mon, 2015-05-11 09:56
A faster, more accurate method to assess cancer risk from certain common environmental pollutants has been developed by scientists. The study focused on an important class of pollutants known as polycyclic aromatic hydrocarbons, or PAHs, that commonly occur in the environment as mixtures such as diesel exhaust and cigarette smoke.

[Review] Soil and human security in the 21st century

Thu, 2015-05-07 20:00
Human security has and will continue to rely on Earth’s diverse soil resources. Yet we have now exploited the planet’s most productive soils. Soil erosion greatly exceeds rates of production in many agricultural regions. Nitrogen produced by fossil fuel and geological reservoirs of other fertilizers are headed toward possible scarcity, increased cost, and/or geopolitical conflict. Climate change is accelerating the microbial release of greenhouse gases from soil organic matter and will likely play a large role in our near-term climate future. In this Review, we highlight challenges facing Earth’s soil resources in the coming century. The direct and indirect response of soils to past and future human activities will play a major role in human prosperity and survival. Authors: Ronald Amundson, Asmeret Asefaw Berhe, Jan W.

Air pollution: Not breathing easy

UK Only Article:&nbsp; UK article only Issue:&nbsp; The dawn of artificial intelligence Fly Title:&nbsp; Air pollution Rubric:&nbsp; A Supreme Court ruling forces the government to deal with dirty air Main image:&nbsp; 20150509_BRP003_0.jpg BRITISH air is much clearer than it once was: in 1952 one “pea souper” smog in London (see photo) caused the deaths of around 4,000 people in a week. But it is not as clean as it could be. On April 29th the Supreme Court ordered the next government to come up with a plan by the end of the year to reduce the amount of nitrogen dioxide (NO{-2}), a noxious gas produced by diesel engines, in the atmosphere. The judgment could have big implications for several large infrastructure projects. It also suggests how, after years of campaigning by greener types, dirty air is finally becoming a political issue. Britain has long been exceeding limits set by the European Union on air pollution. In 2014 the Department for Environment, Food and Rural Affairs reported that, in the previous year, annual ...<div class="og_rss_groups"></div>
