Scientists: water woes ahead
Within a generation, water demand in many countries is forecast to exceed supply by an estimated 40 percent.
In other parts of the world prone to flooding, catastrophic floods normally expected once a century could occur every twenty years instead; meanwhile, spending on technologies and services to discover, manage, filter, disinfect, and desalinate water, improve infrastructure and distribution, mitigate flood damage, and reduce water consumption by households, industry, and agriculture is expected to rise to a trillion dollars annually by 2020 -

Mitigation policy could halve climate-related impacts on water scarcity
Even without the effects of climate change, as much as 40 percent of the world’s population will be living under water scarce conditions by 2020; climate change is expected to influence future water scarcity through regional changes in precipitation and evaporation; most climate models suggest rainfall is likely to decrease in the subtropics and increase in mid-latitudes and some parts of the tropics; in the latter, mitigation efforts could actually reduce the amount of extra water potentially available

Canada's water could be answer for anticipated global water shortages
Global demand for water is projected to exceed supplies by 40 percent in 2030, and Canada may be the answer to minimizing water shortages; it is estimated that in the next twenty years, one third of the world will only have half the water it needs to cover daily needs; to prevent these shortages, researchers are scrambling to develop technologies and practices to reduce water consumption, discover new re-processing techniques, and improve infrastructure; Canada’s water experts are well-suited to assist in this effort as they have gained valuable experience from managing 9 percent of the world’s fresh water supplies

New Zealand quake could take ten years and $15 billion to clean up
David Carter, New Zealand’s acting economic development minister, estimates that it could take ten years to rebuild Christchurch after a 6.3 magnitude earthquake rocked the town last month; the cost of rebuilding is estimated at $15 billion and climbing; nearly a third of the buildings in its business district have been declared unsafe; New Zealand prime minister John Key ruled out an earthquake tax for fear it would hurt the economy, which has been hit hard by the recession; New Zealand is actively soliciting international aid to help with its recovery; Christchurch has a population of roughly 377,000 and makes up about 15 percent of the nation’s economy

Britain struggles to contain rampant copper thefts
Britain is struggling to stop thieves that are stealing large quantities of copper from rail yards; the cost of these thefts to the British government has doubled to roughly $1.25 billion a year; the price of copper has hit all-time highs at just over $10,000 per ton, which has driven organized gangs to conduct dangerous raids on rail way stations; the gangs climb on to the tracks and use power tools to cut down all the copper cables they can including train signaling, electricity, and data cables; thefts are expected to increase as the demand from China is projected to push copper prices even higher

Growth of geothermal energy market lags behind wind and solar
According to a recently released report, the geothermal energy market is expected to grow over the next twenty years, but will still trail far behind wind and solar; currently only twenty-six countries in the world use geothermal energy to generate power, and as of 2010 there was a total global capacity of 10,715 megawatts; in June 2010, total global capacity of wind-powered generators was 175 gigawatts; by 2020 as much as 14.4 gigawatts of new geothermal capacity will be added at a 3 percent annual growth rate; the market value is estimated to be $6.8 billion by 2020; the expansion of geothermal energy still faces several impediments; at least 350 projects currently underway face financing, drilling rig, and skilled labor shortages

Toxic metals from Superfund site endangers wetlands in Ventura County
The Environmental Protection Agency (EPA) recently announced that an old metal recycling plant in Oxnard, California, now a federal Superfund site, was leaking lead, zinc, and other dangerous chemicals into nearby wetlands; when the plant closed, it left nearly 700,000 cubic yards of unattended waste laden with heavy metals and small amounts of radioactive thorium; high costs have hindered cleanup efforts and local residents have become frustrated with the drawn out efforts; the wetlands that are endangered by the old metal recycling plant are located in Ormand Beach and are home to several rare and endangered species

Scientists warn solar storms could be "global Hurricane Katrina"
Scientists warn that massive solar storms could be the equivalent of a “global Hurricane Katrina”; these storms could cause $2 trillion in damages to communications equipment, power grids, and GPS systems; experts are particularly concerned about solar flares due to the increased reliance on electrical communication systems and the approach of a period of intense solar activity; solar flares can cause power surges that are powerful enough to knock out electrical grids and induce electric currents in oil pipelines; in 2013 the sun will enter a peak in its eleven year solar cycle that is expected to generate a significant number of powerful solar flares; last month a solar flare generated magnetic storms and power surges that disrupted communications and grounded flights

Radioactive waste contaminates drinking water, EPA does nothing
Recent Environmental Protection Agency (EPA) documents show that Pennsylvania’s drinking water has been contaminated with radioactive waste from natural gas drilling; energy companies have been extracting natural gas with a new drilling technique called “hydrofracking”; this process results in millions of gallons of wastewater that is contaminated with dangerous chemicals like highly corrosive salts, carcinogens, and radioactive elements; EPA documents reveal the process has been contaminating drinking water supplies across the country with radioactive waste; in Pennsylvania more than 1.3 billion gallons of radioactive wastewater was trucked to plants that could not process out the toxins before it released the water into drinking supplies

Building codes increasingly unable to withstand extreme weather
Basic infrastructure around the world has had increasing difficulty in withstanding more extreme weather patterns; with record snow falls in the Northeastern United States, hundreds of roofs have collapsed under the weight of snow and in 2008 heavy snows in China caused 223,000 homes to collapse resulting in $1 billion in insured damages; engineers and insurers worry that current building designs may not be able to withstand more extreme weather patterns; engineers have built more robust safety mechanisms into their designs, but municipal building codes that determine the minimum standard have lagged behind; insurance companies have changed their policies to offer lower premiums to homes that are better built and have refused to insure homes in high-risk areas

Magnetic battery to monitor buried nuke waste for 100 years
There is a new way to monitor deeply buried nuclear waste: University of Bristol researchers have developed a “battery” that uses a magnetic spring to create the necessary power to send a message from a repository to the outside world 100 years on; Doug Parr, chief scientist at Greenpeace in the United Kingdom, is unimpressed. “Spent fuel remains hazardous for 240,000 years. It’s good to see there’s a possibility of monitoring for the first 100 years — that just leaves the other 99.96% of the time to worry about”

Maryland wants Florida's high speed rail funds
As Republican governors in Florida, Wisconsin, and Ohio reject federal funding for high speed rail projects, states like Maryland are clamoring to receive those funds; Maryland Senators Benjamin L. Cardin and Barbara A. Mikulski sent a letter to Transportation Secretary Ray LaHood requesting that $2.4 billion dollars in high speed rail funding originally designated for Florida be redirected to projects in the Northeast Corridor; each year 250 million rail passengers use the corridor and passenger use is projected to increase by 60 percent by 2030; the White House plans to spend $53 billion on high speed rail projects over the next six years and $8 billion in the coming fiscal year alone
