The world is wasting water on a truly colossal scale, according to the United Nations. More than 80 per cent of the used water on Earth is neither collected nor treated – the equivalent to the planet leaving the taps full on and the plugs out.
Using techniques from drug discovery, and state-of-the-art advances in mathematics, computational algorithms and supercomputing, researchers have developed a tool for identifying the most efficient porous materials for CO2.
Inefficiency, rather than water scarcity, is the greatest global water challenge according to new research published today, which says fears of water shortages are unfounded as major river basins contain enough resources to double food production...
You've heard of carbon footprints. A recent paper delves into humanity's water footprint, the various components that contribute to it, and the international trade of water that's been incorporated into products.
India’s water desalination business is set to triple to $1.2 billion by 2017 as rising demand from industry spurs the South Asian country to build more purification plants, according to a research report.
UNITED NATIONS — The world’s nations achieved a U.N. goal of cutting in half the proportion of people without access to safe drinking water five years ahead of the 2015 target, the United Nations announced Tuesday.
The world's oceans may be turning acidic faster today from human carbon emissions than they did during four major extinctions in the last 300 million years, when natural pulses of carbon sent global temperatures soaring, says a new study in Science.
In the last hundred years, atmospheric CO2 has risen about 30 percent, to 393 parts per million, and ocean pH has fallen by 0.1 unit, to 8.1--an acidification rate at least 10 times faster than 56 million years ago, says Hönisch. The Intergovernmental Panel on Climate Change predicts that pH may fall another 0.3 units by the end of the century, to 7.8, raising the possibility that we may soon see ocean changes similar to those observed during the PETM.
The effects of ocean acidification today are overshadowed for now by other problems, ranging from sewage pollution and hotter summer temperatures that threaten corals with disease and bleaching. However, scientists trying to isolate the effects of acidic water in the lab have shown that lower pH levels can harm a range of marine life, from reef and shell-building organisms to the tiny snails favored by salmon. In a recent study, scientists from Stony Brook University found that the larvae of bay scallops and hard clams grow best at pre-industrial pH levels, while their shells corrode at the levels projected for 2100. Off the U.S. Pacific Northwest, the death of oyster larvae has recently been linked to the upwelling of acidic water there.
