Rivers are Largest Source Of Mercury in Arctic Ocean, Study Says. 22 May 2012: Rivers are Largest Source Of Mercury in Arctic Ocean, Study Says A new study suggests that rivers may be funneling far more toxic mercury into the Arctic Ocean than previously believed, a finding that may portend even greater mercury concentrations in the future as the effects of climate change accelerate the region’s hydrological cycle.

Rivers are Largest Source Of Mercury in Arctic Ocean, Study Says

Despite the Arctic's remoteness, scientists have long known that mercury levels in Arctic mammals are among the highest on the planet, a factor largely attributed to mercury being deposited in the Arctic Ocean from the air. But according to Harvard scientists, circumpolar rivers — particularly three great Siberian rivers, the Lena, Ob, and Yenisei — may be contributing twice as much mercury as the atmosphere. According to the scientists, mercury levels in the Arctic tend to increase sharply during the spring and summer months.

As new maps are created and found, they will be added to the corresponding Pearltree #Watermaps. The Pearltree can be accessed, as for the energy security bibliography, by clicking on the Pearl on the right hand side of this paragraph, or in the embedded application below. You are welcome to share your findings by joining the team on Pearltree. Maps are both necessary tools for analysis and crucial delivery visuals for our foresight and warning products. They constitute a category of delivery form, which can, furthermore, be combined with other categories to suit at best our needs.

Active Fire Mapping Program. Climate change hits globe's water cycle. LIVERMORE, Calif., May 21 (UPI) -- The Earth's dry lands are getting drier and wet ones wetter as climate change shifts and accelerates the globe's water cycle, U.S. researchers say.

Climate change hits globe's water cycle

Changing patterns of salinity in the global ocean during the past 50 years show a clear fingerprint of climate change on the shift in worldwide rainfall and evaporation, they said. Scientists with the Lawrence Livermore National Laboratory in California along with colleagues at Australia's Commonwealth Scientific and Industrial Research Organization say the Earth's water cycle has strengthened by 4 percent 1950-2000. The cycle represents the ratio of rainfall rates with rates of evaporation.

"These changes suggest that arid regions have become drier and high rainfall regions have become wetter in response to observed global warming," LLNL researcher Paul Durack said. Changes in ocean salinity can be directly linked to climate change, researchers said. Now blue rating water standards for industry. The Union Ministry of Water Resources has asked the CII to frame guidelines for increasing water efficiency in Indian industries.

Now blue rating water standards for industry

The CII is likely to come up with the water standards by March next year News | NEW DELHI, INDIA: India is set to become the first country in the world to come up with "blue ratings" - on the lines of green ratings for eco-friendly ventures - for increasing management of water, fast turning a scarce resource, in industry. The Union Ministry of Water Resources has asked the Confederation of Indian Industry (CII) to frame guidelines for increasing water efficiency in Indian industries.

Egypt revolution doesn’t affect Nile Basin countries' stance on new agreement. Egypt’s revolution would not change Tanzania’s stance on a water-sharing agreement that would strip Egypt of its historical Nile water share, a Tanzanian minister said, according to privately owned Al-Shorouk newspaper.

Egypt revolution doesn’t affect Nile Basin countries' stance on new agreement

Mahadhi Maalim, deputy minister of foreign affairs and international cooperation, said upstream countries desperately need to make use of their water resources and not antagonize other countries. In April 2010, Rwanda, Kenya, Tanzania, Ethiopia and Uganda signed the Entebbe framework agreement, which aimed to redistribute Nile water shares. Burundi joined the agreement in March 2011.

Sudan and Egypt opposed the deal on the basis that it threatens their historical water share granted by a 1959 agreement made with Sudan under British occupation. Maalim said negotiation is the only and best way to resolve any conflict among the upstream and downstream countries when it comes to Nile water issues.

L’Atalante, navire de la flotte Ifremer©Ifremer/Michel GOUILLOU Source IFREMER La campagne océanographique franco-allemande BIONOD [1] (contraction de BIOlogie et NODules) a débuté le 27 mars à bord du navire L’Atalante de l’Ifremer. Elle se poursuivra pendant un mois et demi, jusqu’au 10 mai prochain, dans le Pacifique nord-est, dans la zone de Clarion-Clipperton, entre l’archipel d’Hawaï et la côte ouest du Mexique. La campagne BIONOD répond aux engagements de la France vis-à-vis de l’Autorité internationale des fonds marins [2] qui lui a attribué un secteur de 75 000 km2 pour l’exploration des nodules polymétalliques [3].

A Tour of Drought as it Unfolds Across the U.S. Last year at this time, all eyes were on Texas, where drought conditions were intensifying into what became that state’s worst single year drought on record, causing nearly $8 billion in economic losses. Recently, though, Texas has gone from famine to feast in the precipitation department, and drought concerns for the upcoming summer are focused farther to the west, as drought tightens its grip across a broad swath of the interior West and Southwest In addition to the West, drought conditions are also prevalent in the Southeast, Mid-Atlantic, and parts of the Northeast as well, along with a small pocket in the Upper Midwest.

In all, 56 percent of the Lower 48 states were experiencing drought conditions as of May 8, almost twice the area compared to last year at this time, according to data from the U.S. Drought Monitor.

Unsustainable water. South American drought fuels fears of food price shocks, as soya bean harvests suffer The viability of water supplies throughout key regions of China, India, Pakistan, South Africa and the US are under threat from unsustainable domestic, agricultural and industrial demands, according to a new study that maps water use down to 10km² worldwide. The growth economies of China and India, and the world’s largest economy USA are identified by risk analysis company Maplecroft, in its newly released Water Stress Index, as having vast geographical regions and sector areas where unsustainable water use is outstripping supply. Maplecroft states that the situation so serious, it has the potential to limit economic growth by constraining business activities, as well as hampering agricultural outputs.

Water stress has major implications for global supply chains, especially within the major growth economies.

Source found for missing water in sea-level rise. / SuperStock Human water use, for example in irrigation, makes a substantial contribution to sea-level rise. Climate change, with its associated melting ice caps and shrinking glaciers, is the usual suspect when it comes to explaining rising sea levels. But a recent study now shows that human water use has a major impact on sea-level change that has been overlooked.

During the latter half of the twentieth century, global sea level rose by about 1.8 millimetres per year, according to data from tide gauges. The "Inconvenient Truth" Film About Water.
