Tunis, Tunisia: A remote seasonal salt lake on the edge of the Sahara leads a list of 15 new Ramsar Wetlands of International Importance being declared in the country on World Wetlands Day, February 2. Chott Elguetar, a 7,400 ha site with an intermittent lake, is vital to the survival of the threatened Scimitar Oryx, Addax and Dama Gazelle. It also contains traces of human religious and industrial activity that have been dated back 40,000 years.

World Wetlands Day (WWD) is an annual celebration held on the 2nd February in order to raise worldwide awareness of the importance of wetlands. The date is particularly significant, marking the anniversary of the adoption of the Convention on Wetlands, also known as the Ramsar Convention, which is an international treaty that represents the commitment of its members to the preservation of their wetlands.

The European Commission has unveiled a new set of water pollution rules, which will for the first time include certain pharmaceutical products. The Commission is proposing to add 15 chemicals to the list of 33 pollutants that are currently monitored and controlled in EU surface waters. The popular pain-relieving drug Diclofenac is one of three pharmaceuticals to be put on the European water watch-list, which law-makers say is another step towards improving the quality of rivers, lakes and coastal waters. The 15 substances include industrial chemicals as well as compounds used in biocides and plant protection products. They have been selected on the basis of scientific evidence that they may pose a significant risk to health.

It's good news for the human environment. The UPS Foundation today announced almost 120 grants totaling more than $6 million to non-profit organizations around the world that champion diversity and support diverse communities. For more than 60 years, UPS's philanthropic arm has funded organizations that support under-served and under-represented members of society. This year’s grants will support a wide range of programs, including those for wounded veterans, the hearing and visually-impaired, women and girls and culturally distinct populations.

New research led by scientists from Oxford University and Exeter University has shown that the invasion of the land by plants in the Ordovician Period (488-443 million years ago) cooled the climate and may have triggered a series of ice ages. During this period sea levels are very high and at the end of the period there was a mass extinction event. At the beginning of the period, around 480 million years ago, the climate was very hot due to high levels of CO2, which gave a strong greenhouse effect. The marine waters are assumed to have been around 45°C, which restricted the diversification of complex multi-cellular organisms. But over time, the climate become cooler, and around 460 million years ago, the ocean temperatures became comparable to those of present day equatorial waters. The dramatic cooling of the planet between 300 and 200 million years ago was also the result of the evolution of large plants with large rooting systems that caused huge changes in both of these processes. In the current results it was shown that the appearance of the first land plants had a similar effect and much earlier in time.

The UN High-Level Panel Global Sustainability released its report in Addis Ababa yesterday entitled Resilient People, Resilient Planet: A Future Worth Choosing. The panel’s 99-page report, which will serve as an input to the UN Conference on Sustainable Development in June, (otherwise known as the Rio+20 Summit) is a call to action, "to address the sustainable development challenge in a fresh and operational way." This document is incredibly rich, beautifully written and filled with a tremendous amount of good thought, clear vision, careful analysis, sober assessment, and useful suggestions for ways to move sustainable development from an abstract concept to the core of mainstream economics.

The National Oceanic and Atmospheric Association today designated the Atlantic sturgeon an endangered species, providing it greater legal protections, following a petition the Natural Resources Defense Council submitted in September 2009. NOAA's Fisheries Service today announced four subpopulations or distinct population segments of Atlantic sturgeon, which are treated as individual species under the law, will be listed as endangered under the Endangered Species Act: the New York Bight, the Chesapeake Bay, the Carolina, and the South Atlantic. The northernmost distinct population segment, the Gulf of Maine, will be listed as threatened.

After more than four years in the making, media reports and hype, visits to the Better Place Education and Test Drive Center and final delivery prices, Better Place Renault Fluence ZE electric cars are finally on their way to purchasers in Israel. In a high profile ceremony on Sunday, January 22, which we were invited to but could not make because of the rain, Better Place launched its first 100 cars sent off to customers from the Better Place Israel headquarters near Tel Aviv. The cars, all Renault Fluences that had been specially built for running exclusively on electricity were sent off in a ceremony that included Shai Agassi, Better Place USA CEO, Idan Ofer Chairman of the Board, and Moshe Kaplansky, CEO for Better Place Israel.

A University of Bristol team has dissolved iron in liquid surfactant to create a soap that can be controlled by magnets. The discovery could be used to create cleaning products that can be more easily removed after application and used in the improved recovery of oil spills at sea. Scientists from the University of Bristol have developed a soap, composed of iron rich salts dissolved in water, that responds to a magnetic field when placed in solution. The soap’s magnetic properties were proved with neutrons at the Institut Laue-Langevin to result from tiny iron-rich clumps that sit within the watery solution. The generation of this property in a fully functional soap could reduce environmental concerns over the use of soaps (lingering soap residue) in oil-spill clean ups and revolutionize industrial cleaning products.

People exposed to very high levels of arsenic in Chilean drinking water back in the 1950s and 60s are still showing a higher-than-normal risk of bladder cancer -- years after the arsenic problem was brought under control, a new study shows. The findings are not surprising, researchers say, since the cancer would take decades to emerge. But the results underscore the importance of continuing to screen high-risk people for bladder cancer, according to lead researcher Dr. Fernando Coz, a professor of urology at the Universidad de Los Andes in Santiago de Chile. The study, reported in the Journal of Urology, focused on people in the Antofagasta region of Chile. In the 1950s and 60s, drinking water in the region became contaminated with high levels of arsenic. Arsenic is semi-metallic element found in rock, soil, water and air. It is also released into the environment through industrial activities, and can be found in products like paints, dyes and fertilizers. High exposure has been linked to several cancers, including tumors of the bladder, liver and lungs.

In the first published results from a clinical trial using human embryonic stem cells, two legally blind patients who received an injection of hESC-derived cells in one eye have experienced no harmful side effects and appear to have slightly better vision. Although the result is preliminary, it is an important milestone for the struggling hESC field.

The speed of light is considered to be the limit at which no object can go faster. But here on Earth, nature has its own speed limit which affects its fastest creatures every day. The speed at which an animal can go, and human aircraft for that matter, is directly dependent upon how far that animal can see. Using complex mathematical equations, researchers at the Massachusetts Institute of Technology (MIT) have effectively quantified nature's speed limit. They found that given a certain density of obstacles, there exists a speed at which a bird can reasonably fly without collision.

The Sumatran elephant subspecies (Elephas maximus sumatranus) was downgraded to critically endangered on IUCN's Red List of Threatened Species on Tuesday, prompting environmental group WWF to call for an immediate moratorium on destruction of its rainforest habitat, which is being rapidly lost to oil palm estates, timber plantations for pulp and paper production, and agricultural use.

New research has found that solar output is likely to reduce over the next 90 years but that will not substantially delay expected increases in global temperatures caused by greenhouse gases. Carried out by the Met Office and the University of Reading, the study establishes the most likely changes in the Sun's activity and looks at how this could affect near-surface temperatures on Earth.

Storm water run-off, a major problem which has affected Singapore for two consecutive years, is thought to be partially due to urbanization of the country, and recommendations have been made for mitigation of this serious issue. An expert panel consisting of 12 members was created after last year's flash flooding across eastern and central Singapore to research potential solutions, and the panel explains that urbanization – that is, more concrete, buildings and roads due to a growing population – is one of the reasons behind the recent increase in storm water run-off which causes the flooding. Today Online mentions that the panel performed additional analysis as a joint effort with the Meteorological Services, and observed that there are clear trends in recent decades towards higher rainfall in terms of intensity and frequency. These findings are consistent with the Intergovernmental Panel on Climate Change's (IPCC) findings.

Global action against climate change is often difficult and excruciatingly slow. For the United States, policies to combat a warming Earth are at a virtual standstill. That is why it comes down to local and regional alliances to work together to make a difference. In the US, there are few areas more vulnerable to climate change than southern Florida. It is an area that will be easily inundated with flooding should seas continue to rise and hurricanes continue to batter them. Now, four south Florida counties have teamed together to prepare their communities for the menace that is to come.

When it comes to commercial whaling, things are rarely as simple as they seem. The fact that it continues, 30 years after the International Whaling Commission (IWC) voted for an indefinite moratorium, suggests that there has been some kind of failure on the part of environmentalists and other opponents of whaling; yet the number of whales being killed by whalers today is a fraction of what it was three decades ago, and a barely noticeable blip when set against the size of the industry at its peak. And although the whaling nations' self-assigned quotas may be higher than they were a few years ago, the actual catches fall some way short of those quotas.

A US-backed billion-dollar gold mine has attracted thousands of protestors in recent weeks. Many have the poor economic legacy of existing mines fresh in their minds, reports Gervase Pouldon in Cajamarca, Peru. For Segundo Ortiz, a worker at the San Antonio Market in Cajamarca, a city in the north of Peru, the reasons for taking to the street in protest are clear: 'It’s about protecting our water supply, nothing more.'

Puntung is a Sumatran rhino, one of roughly two hundred left in the world. Captured in a Borneo forest on Christmas Day, she is the latest addition to Malaysia's Borneo Rhino Sanctuary -- and experts say she may also be one of the last hopes for a species on the brink of extinction. Veterinarians want to introduce Puntung to Tam, a 20-year-old male Sumatran rhinoceros in the enclosure next door, in the hopes that they will breed -- although this cannot take place for a number of months yet, until Puntung is deemed ready. Estimated to be 10 to 12 years old, she was airlifted to the sanctuary in the Tabin Forest Reserve after her capture, and has since been adjusting to her new home, eating more than 60 kg (132 lb) of leaves each day. "She doesn't look stressed, she's eating well ... but the stress (of a new environment) is enough to offset her cycle, her normal cycle," said Zainal Zahari Zainuddin, a veterinarian with the Borneo Rhino Alliance. "So she may not have a cycle now. That's why we're monitoring her." Captive breeding is now regarded as the only way to boost the population of the two-horned Sumatran rhino, which at 500 to 600 kg (1,100 to 1,322 lb) and 1.3 metres tall (4.3 feet) is the world's smallest rhinoceros.

The concept of the hydrogen economy (HE), in which hydrogen would replace the carbon-based fossil fuels of the twentieth century was first mooted in the 1970s. Today, HE is seen as a potential solution to the dual global crises of climate change and dwindling oil reserves. A research paper to be published in the International Journal of Sustainable Design suggests that HE is wrong and SHE has the answer in the sustainable hydrogen economy. John Andrews of the School of Aerospace, Mechanical and Manufacturing Engineering, at RMIT University, in Bundoora, Victoria, Australia, explains how rather than there being a straight choice between hydrogen fuel cells and battery electric vehicles, it is time to accept that horsepower is a matter of "horses for courses." He adds that hydrogen can be produced using renewables -- water as the material source and wind power or solar as the energy supply for conversion. It thus offers a zero-emissions approach to fuel production for power generation using fuel cells to convert the hydrogen into electricity for all modes of transport as an alternative to petroleum fuels. Hydrogen generated by via wind power can also act as an energy-storage medium for times when wind and sun are unable to fulfill power requirements.
