18 May 2012: EU Fisheries Observers
Are Intimidated, Bribed by Crews

Observers placed on European Union fishing boats to reduce the amount of illegal and unreported catches are often subject to threats, intimidation, and bribes when they try to do their jobs, according to a report in the Guardian. After interviewing more than 20 former and current fisheries observers and examining EU records, the newspaper said that the threats and harassment are common on Spanish and Portuguese fishing boats, which are notorious for egregious overfishing. The observers told the Guardian that crew members would steal their records of fishing violations, threaten them with an “accident” at sea, kick their cabin doors to keep them awake at night, and take elaborate steps — including making illegal hauls while observers were eating — to conceal the extent of overfishing. Independent observers are placed aboard every vessel operating in the Northwest Atlantic Fishery Organization. But because of fishing industry pressure, observers who spot violations are only allowed to summon an inspector on board, but cannot provide the inspector with any details or records of infractions.

11 May 2012: Eel Breeding Innovation
Sought to Conserve Wild Populations

Japanese biologists are racing to develop a type of food that would enable fish farmers to breed eels on a commercial scale using for the first time larvae produced in captivity, a step that could reduce pressures on collapsing eel populations worldwide. While farmers have long bred captive eels — a popular delicacy in many countries — until now they have only been able to do so on a commercial scale using baby eels trapped in the wild, a step that has exacerbated the catastrophic decline in wild eel populations from the Far East to North America. The reason, scientists say, is that it has been difficult and expensive to produce the foodstuff critical to the development of eel larvae: a mixture of marine detritus known as “marine snow.” Scientists so far have considered a wide range of possible ingredients, including the yolk from shark’s eggs. “Whoever gets there first has made a tremendous discovery; you’re recovering a cultural tradition,” David Righton, a scientist with the UK-based Cefas marine laboratory, told the Guardian. “Whoever does this is culturally important as well as becoming very rich.”

09 May 2012: Warming Waters Attract
New Fish Species to British Waters

Warming ocean temperatures have changed the distribution of many critical marine species off the British coast, as warm water fish are increasingly expanding into northern waters and cold-water species are swimming to colder depths, according to a new report. The report of the Marine Climate Change Impacts Partnership, published by the UK and Scottish governments, found that warm water species such as the bluefin tuna and thresher sharks are more frequently appearing in the waters off southwest England and squid have become increasingly abundant in the North Sea. One southern species, the bib, has moved north by 212 miles (342 kilometers) in the last two decades, while common North Sea species such as cod and lemon sole are swimming at an average of 5.5 meters deeper per decade. The report, based on an analysis of scientific studies, warns these changes pose potential threats for native species and the commercial fishing industry as changing water temperatures could introduce invasive species and new diseases.

09 May 2012: Groundwater Pumping Emerges
As a Factor in Sea Level Rise, Study Says

The vast amounts of water pumped out of the ground for irrigation, drinking water, and industrial uses will increasingly contribute to global sea level rise in the coming decades, according to a new study. According to researchers at Utrecht University, humans pumped about 204 cubic kilometers (49 cubic miles) of groundwater in 2000, much of which evaporated into the atmosphere before ultimately entering rivers, canals and, eventually, the world’s oceans. While in earlier decades the rise in sea level caused by groundwater removal was canceled out by the construction of dams, that changed by the 1990s as humans pumped more groundwater and built fewer dams. By 2000, groundwater extraction resulted in a sea level rise of about 0.57 millimeters annually — compared with about 0.035 millimeters in 1990. According to the study, published in Geophysical Research Letters, by 2050 the pumping of groundwater worldwide could cause sea levels to rise about 0.8 millimeters annually.

01 May 2012: Oil and Gas Companies See
Offshore Wind Potential in North Sea

An increasing number of oil service companies are working with renewable energy companies to develop offshore wind projects in the North Sea as the region’s fossil fuel resources dwindle and demand for clean energy rises. According to a report by Bloomberg News, companies such as Technip and Subsea 7 are seizing on the similarities between developing deepsea oil installations and building offshore wind platforms. For wind energy developers, as much as 25 percent of capital spending includes services that can be performed by oil and gas companies, said Jayesh Parmar, a UK-based consultant at Baringa Partners LLP. “The synergies available between offshore wind and oil and gas are most apparent in the North Sea,” Parmar said. “It makes sense here to be operating in both areas.” With numerous offshore wind projects planned, the European Wind Energy Association predicts that more than 446,000 people will work in the North Sea’s offshore wind sector by the end of the decade, twice the current workforce.

24 Apr 2012: European Satellite Provides
Precise Data On Arctic Sea Ice Thickness

The European Space Agency’s (ESA) CryoSat satellite is now providing highly accurate data on the thickness and volume of Arctic Ocean ice. Using a high-resolution synthetic aperture radar that sends down pulses of microwave energy, the satellite can measure the difference between the top of the ice and water in the cracks, or leads, that separate the floes. By measuring the height of the ice above water, which usually represents only one-eighth of total ice thickness, the satellite can provide data on ice thickness to within 10 to 20 centimeters, or 4 to 8 inches. The CryoSat satellite was launched in 2010, and since then scientists have been validating the measurements against other data from plane-based instruments and direct, on-ice measurements. "We now have a very powerful tool to monitor the changes taking place at the poles,” said Volker Liebig, the ESA’s director of Earth Observation.

U.S. and UK officials have announced plans to work together in developing floating wind turbine technology, an innovation that could open new areas of the world’s oceans to wind energy generation. In a collaboration announced in London, U.S. Energy Secretary Steven Chu and UK Energy Secretary Edward Davey said they would help fund research into floating platforms that would support turbines in waters as deep as 500 feet, where wind speeds are consistently higher than near-shore wind farm sites. Officials hope floating turbine technology will reduce the costs of offshore wind, avoiding expenses associated with building on seabed foundations and allowing turbine repairs to occur in port rather than on the water. “Floating wind turbines will allow us to exploit more of our wind resource, potentially more cheaply,” Davey said.

A German startup has developed a new type of lightweight solar panel its developers say can be integrated into the design of buildings and even used in electricity-producing tinted windows. Designed by Dresden-based Heliatek, the technology utilizes small, organic molecules in the production of the solar cells. While such organic solar cells have become commonplace, this technology uses molecules called oligomers. They are more stable than the commonly used polymers, which developers say will make the cells more efficient and longer-lived. Because they are lighter and have greater flexibility than most panels, the company hopes they can be integrated into building construction as a cheaper alternative to mounted panels, according to MIT’s Technology Review. The company also is working with a manufacturer to use the semi-transparent panels as windows.

studies conducted over the past 50 years, scientists at Oregon State University (OSU) found that the loss of mammalian predators in forest ecosystems across North America, Europe and Asia — including killings to prevent ranching conflicts — has allowed an increase in populations of moose, deer, and other large herbivore species, which in turn has impaired the growth of young trees. According to the researchers, population densities of large herbivores were six times greater in areas without wolves. The researchers say the presence of predators not only limits the size of herbivore populations but affects their behavior, a factor they call the “ecology of fear.” “There’s consistent evidence that large predators help keep populations of large herbivores in check, with positive effects on ecosystem health,” said William Ripple, a professor of forestry at OSU and lead author of the study, published in the European Journal of Wildlife Research.

04 Apr 2012: Cracking of Matterhorn
Is Linked to Warming Climate

An increase in glacial meltwater atop the Matterhorn is causing large pieces of rock to tumble from the iconic Alpine mountain, a new study has found. Using a series of monitoring devices on 17 areas, researchers from the University of Zurich found that an increasing amount of water has penetrated exposed cracks and fissures on the 14,690-foot mountain, which straddles the Swiss-Italian border. During subsequent cycles of freezing and thawing, that water is triggering subtle movements beneath the rock surface, causing wider fissures. “There has been a big increase in the number of rock falls in the past decade that can’t be explained simply by the fact that we’re looking out for them more now,” Stephan Gruber, lead author of the study, told The Independent. The findings, he said, may suggest that similar processes are occurring at the same altitude elsewhere in the Alps. The study, which was initiated after a massive rock fall from the mountain in 2003, is published in the Journal of Geophysical Research.

03 Apr 2012: UK Revives £1 Billion Contest
To Boost Carbon Capture Sector

The UK has re-launched a £1 billion ($1.6 billion) competition to promote the large-scale adoption of carbon-capture technology, an investment that government officials hope will make the UK a global leader in the emerging low-carbon energy sector. Launched by the Department of Energy and Climate Change (DECC), the program will offer funding for the development of one or more plants capable of removing carbon emissions from coal-fired power plants and storing them underground. While some call such carbon capture and storage (CCS) technology a potentially critical part of reducing atmospheric levels of carbon dioxide, the sector remains unproven and costly at a large scale. Ed Davey, secretary of the DECC, predicted the sector could be worth £6.5 billion annually to the UK by the end of the 2020s and become operational at 12 to 20 large power plants, producing up to 30 gigawatts of power. An earlier CCS competition in the UK faltered when the final bidder withdrew because of disagreements over government funding.

02 Apr 2012: Some Corals More Resilient
To Increased Acidification, Study Shows

Some coral species may be better able to cope with the increasingly acidic condition of the world’s oceans than previously believed, a new study says. Writing in the journal Nature Climate Change, an international team of scientists describes an internal mechanism by which many coral species are able to buffer against the rising pH levels and still form healthy skeletons. According to the scientists, coral species with skeletons made of aragonite — including the well-known Porites and Acropora corals — contain molecular “pumps” that enable them to regulate internal acid balance. Corals that form calcite skeletons, however, do not have this mechanism. Also, the researchers found that coralline algae — which they describe as the “glue” that holds coral reefs together — remain vulnerable to ocean acidification. In another study, scientists at the Scripps Institution of Oceanography have documented how temperatures in the upper regions of the world’s oceans have increased by an average of .59 degrees F (.33 degrees C) over the last 140 years, with the greatest temperature increases occurring at surface levels, where temperatures rose by an average of 1.1 degrees F.

30 Mar 2012: Scientists Unlock Mystery
Of Where CO2 Was Hidden During Ice Ages

The question of why atmospheric concentrations of CO2 fall during ice ages, and where that CO2 is stored, seems to have been answered by Swiss and German scientists. Using a new method of measuring isotopes in CO2 trapped in Antarctic ice cores, the scientists determined that in periods of global cooling, the oceans absorb more CO2 and store it deep underwater. As the Earth warms because the tilt of its axis enables it to absorb more energy from the sun, changes in ocean circulation transport CO2 from the deep sea to the surface, where it is released into the atmosphere. The Swiss and German scientists were able to determine through an isotopic “CO2 fingerprint” that the released carbon dioxide came from the deep ocean. The research, published in Science, holds important lessons for climate science today, since atmospheric concentrations of CO2 — now close to 400 parts-per-million — are higher than they have been in 800,000 years and are warming the planet. Since warmer oceans absorb less CO2 than colder oceans, the mechanism of deep-sea storage of CO2 could be disrupted, further increasing carbon dioxide concentrations in the atmosphere.

26 Mar 2012: Denmark Aims to Achieve
35 Percent Green Energy by 2020

The Danish government has approved a series of goals to significantly reduce its carbon emissions and increase its use of green energy by 2020, an “ambitious green transition” officials say will affect all levels of society. The agreement, which was approved by parliament last week, targets cutting greenhouse gas emissions by 34 percent by 2020, compared with 1990 levels, and reducing gross energy consumption by 12 percent compared with 2006 levels. By 2020, Denmark plans to obtain 35 percent of its energy from renewable sources and 50 percent of its electricity from wind power. To achieve these goals, the agreement calls for improvements to Denmark’s smart grid, the retrofitting of buildings, expansion of biogas, and increased use of electricity and biomass for the transportation sector. “This will prepare us for a future with increasing prices for oil and coal,” Martin Lidegaard, Denmark’s minister for Climate, Energy and Building, told the Guardian. The Danish government has set a target to meet all of its energy needs from renewable sources by 2050.

21 Mar 2012: Proposed UK Plant Would
Capture 90 Percent of CO2 Emissions

A U.S.-led consortium has announced plans to build a new coal plant in Scotland that it says will be able to capture 90 percent of its carbon emissions. The so-called Caledonia Clean Energy Project, which would be built near Edinburgh, is perhaps the most ambitious carbon capture and storage (CCS) proposal so far in the UK, where earlier projects have struggled to get off the ground. The proposal — which would be developed by the Seattle-based Summit Power Group — received qualified endorsements from some UK environmental groups, but is expected to meet resistance since current plans would use some of the captured CO2 to increase oil production near the North Sea. Summit Power is already developing a similar $450 million project in Texas. In the UK, several carbon-capture projects have been dropped in recent years, and last year the government scrapped plans to invest £1 billion in a full-scale pilot project. While carbon-capture technology is in its early stages — and remains cost-prohibitive on a commercial scale — advocates say it could become a critical option in reducing CO2 concentrations in the atmosphere.

The drilling technique, known as fracking, involves blasting a mix of water, sand, and chemicals deep underground to shatter shale formations and free natural gas trapped within. “Some of the shales don’t respond as well to hydraulic fracturing,” Tillerson told reporters, according to Bloomberg News. “It’s going to take research and time in the lab to understand that.” Tillerson said some shale formations in the U.S. have also been impervious to fracking, and that the company is studying whether the use of different fluids or pumping techniques will make a difference. The rapid spread of the drilling technique has caused increasing concern among environmentalists and some local residents, who contend it may pollute water supplies.

05 Mar 2012: Protected Mediterranean Reefs
Show a Large Gain in Biomass and Diversity

A study of rocky reefs in the Mediterranean Sea shows that those accorded the highest protection, with all fishing prohibited, not only had a greater abundance and diversity of fish, but also demonstrated robust ecosystem health all the way down to the level of marine algae. Enric Sala, a National Geographic explorer-in-residence and marine ecologist at the Center for Advanced Studies of Blanes in Spain, led a study of rocky reefs in numerous regions of the Mediterranean. The study found “remarkable variation in the structure of rocky reef ecosystems,” with a three-decade-old protected area off of Catalonia in Spain showing large numbers of predatory and other fish, while unprotected reefs off the Greek and Turkish coasts were “bare.” The study, published in the journal PLoS ONE, found that that there was not a significant difference in ecological health between reefs that were partially protected, allowing some fishing and other activities, and those that had no protection at all. The conclusion, said Sala, is that to fully protect reefs and nurture biodiversity on them, “no take” fishing zones must be established and strictly enforced.
