• Californians mull life with less water

    Following Californian governor Jerry Brown’s decision to enforce mandatory water restrictions for the first time in history, Californians are planning for changes in their daily lives. Experts say, though, that California cannot resemble its drier neighbor, Arizona. “Without water, you can’t live in California,” Stanford University’s Bill Whalen. “It ties into the California psyche. They have plush lawns and nice gardens that require lots of water. They have the ocean and Lake Tahoe skiing. You have a nice car. You want it clean. You need water. You can’t have California agriculture without water. You lose the nation’s salad bowl.”

  • NASA putting satellite eyes on threat to U.S. fresh water

    Algal blooms are a worldwide environmental problem causing human and animal health risks, fish kills, and taste and odor in drinking water. In the United States, the cost of freshwater degraded by harmful algal blooms is estimated at $64 million annually. In August 2014, officials in Toledo, Ohio, banned the use of drinking water supplied to more than 400,000 residents after it was contaminated by an algal bloom in Lake Erie. NASA has joined forces with the U.S. Environmental Protection Agency, National Oceanic and Atmospheric Administration, and U.S. Geological Survey to transform satellite data designed to probe ocean biology into information that will help protect the American public from harmful freshwater algal blooms.

  • Californians hoping the state would innovative itself out of a water crisis

    California’s water agencies have relied on innovation to cope with the worsening drought and depleting water resources. Irrigation systems have evolved overtime to help the agriculture sector maintain crop yields as temperatures rise and wells begin to dry up.Some are hoping the state would innovate itself out of a water crisis.

  • As the drought worsens, California’s conservation measures fall short

    As the drought worsens, California is doing a poor job of conserving water. Water use has declined by only 2.8 percent in February compared with the same time in 2013. Some Southern Californians are actually increasing their water use. “These are sobering statistics — disheartening statistics, considering how hard we have been working on this,” said Felicia Marcus, chairwoman of California’s water control board, which reported the findings. “We are very concern about these numbers. They highlight the need for further action.”

  • 70 percent of glaciers in Western Canada will be gone by 2100

    There are over 17,000 glaciers in B.C. and Alberta and they play an important role in energy production through hydroelectric power. The glaciers also contribute to the water supply, agriculture, and tourism. A new study says that 70 percent of glacier ice in British Columbia and Alberta could disappear by the end of the twenty-first century, creating major problems for local ecosystems, power supplies, and water quality.

  • Calif. business leaders: State’s worsening water situation threatens economic havoc

    California’s drought outlook is alarming to the point that Governor Jerry Brown recently announced the first-ever mandatory restrictions on water usage, aimed at reducing the state’s urban water use by 25 percent. For much of its history, California has measured up to its challenges while maintaining a healthy economy. Business leaders in the state say that the time has come for California once again to take bold actions to ensure a sustainable future. “We have a choice between protecting our economy by protecting our environment — or allowing environmental havoc to create economic havoc,” said former U.S. Treasury Secretary Robert Rubin, who now co-chairs the Risky Business Project.Driscoll’s CEO Miles Reiter agrees: “The state of California has to deal with groundwater, or we’re going to ruin this state,” he said.

  • $500 million, 5-year plan to help Miami Beach withstand sea-level rise

    Miami Beach is investing up to $500 million in a new five-year plan to fortify its coastline against flooding caused by sea-level rise. Between seventy to eighty pumps that will be installed to drain the streets of water as it comes in. Additionally, the city is planning to raise roadways and sidewalks by 1.5 to 2 feet along the western side, which faces the Biscayne Bay. Florida is already seen as one of the most vulnerable states to climate change. Over the past 100 years, sea levels along the coast have risen 8 to 9 inches and are expected to rise by between three and seven inches within the next fifteen years, according to federal government projections.

  • California imposes first mandatory water restrictions in state history

    Standing on a patch of brown grass in the Sierra Nevada mountains, which is usually covered with several feet of snow at this time of the year, California governor Jerry Brown announced the first mandatory water restrictions in state history. “Today we are standing on dry grass where there should be five feet of snow,” Brown said yesterday. “It’s a different world… we have to act differently.”About 30 percent of California’s water supply comes from the Sierra Nevada snowpack, so less snow means less snowmelt, which means less water.

  • Extended Oregon drought raises concern over state’s water security

    Facing the fourth straight year of drought, Oregon officials are worried that the state’s water security may be in jeopardy, as is already the case in California, which has just announced its first-ever mandatory water restrictions. a historically warm winter this season has continued to shrink snowpack throughout the Oregon Cascades, including the usual five-foot levels which accumulate on Mt. Hood, leading experts to suggest that even bigger problems lie ahead. Without the usual snowfall, Oregonians can expect fewer healthy fish in the rivers, fewer seed sprouts, and more wild fires. Moreover, the need for more irrigation could hamper the state’s already hobbled farming economy.

  • Water scarcity a contributing cause of wars, terrorism in Middle East, North Africa

    The UN defines a region as water stressed if the amount of renewable fresh water available per person per year is below 1,700 cubic meters. A region is experiencing water scarcity if the figure is below 1,000 cubic meters, and below 500 amounts to “absolute water scarcity.” Water scarcity driven by overuse, poor land management, and climate change, is one of the causes of wars and terrorism in the Middle East and North Africa. If governments fail to respond, shortages of major resources, including food and energy, will cause greater insecurity and conflict.

  • For soybean growers, hidden cost of climate change exceeds $11 billion

    Even during a good year, soybean farmers nationwide are, in essence, taking a loss. This is because changes in weather patterns have been eating into their profits and taking quite a bite: $11 billion over the past twenty years. This massive loss has been hidden, in effect, by the impressive annual growth seen in soybean yields thanks to other factors. That growth, however, could have been 30 percent higher if weather variations resulting from climate change had not occurred, according to a new study.

  • U.K. coastal railways at increasing risk from climate change

    Footage of a railway line suspended in mid-air and buffeted remorselessly by the storm that had caused the sea wall to collapse beneath it made for one of the defining images of 2014. Scenes such as those witnessed at Dawlish in Devon are set to become more frequent as a result of climate change, and the U.K. government and rail companies must face up to difficult funding decisions if rural areas currently served by coastal lines are to continue to be connected to the rail network. For railway builders in the mid-nineteenth century the coast was cheaper, flatter, and easier than using inland sites, one expert points out. “We wouldn’t have built these railway lines where they are if we had today’s knowledge.”

  • World population may outpace water supply by mid-century

    Population growth could cause global demand for water to outpace supply by mid-century if current levels of consumption continue. It would not, however, be the first time this has happened, a new study finds. Using a delayed-feedback mathematical model which analyzes historic data to help project future trends, the researchers identified a regularly recurring pattern of global water use in recent centuries. Periods of increased demand for water — often coinciding with population growth or other major demographic and social changes — were followed by periods of rapid innovation of new water technologies that helped end or ease any shortages. The researchers’ conclusions: Technological advances will be needed in coming decades to avoid water shortages.

  • Rising sea level will double Hawaii’s coastal erosion by mid-century

    New research brings into clearer focus just how dramatically Hawaiʻi beaches might change as sea level rises in the future. Chronic erosion dominates the sandy beaches of Hawaiʻi, causing beach loss as it damages homes, infrastructure, and critical habitat. Researchers have long understood that global sea level rise will affect the rate of coastal erosion. The research team developed a simple model to assess future erosion hazards under higher sea levels, taking into account historical changes of Hawaiʻi shorelines and the projected acceleration of sea level rise reported from the IPCC. The results indicate that coastal erosion of Hawaiʻi’s beaches may double by mid-century.

  • Policy makers discount damages from future climate tipping points – but they should not

    Most methods that weigh up the costs and benefits of tackling climate change ignore climate tipping points, and especially the uncertainty surrounding them. Instead, they assume that future damages from climate change are known perfectly and can therefore be discounted at a rate comparable to the market interest rate – thus reducing the willingness to pay now to protect future generations. New research shows, however, that the prospect of an uncertain future tipping point should greatly increase the amount we are willing to pay now to limit climate change. The study argues that society should set a high carbon tax now to try and prevent climate change reaching a point of no return.
