• Climate change and cities: a wake-up call

    More than half the world’s population live in cities, many of which are increasingly vulnerable to the impacts of climate change; cities, however, are also emerging as the innovative “first responders” in dealing with climate change; climate change will stress cities in many ways — there will be more heat waves, threatening the health of the elderly and infirm; droughts will also become more commonplace in many cities, while in coastal communities too much water may be the problem, due to sea-level rise and more extreme coastal flooding

  • Deadly tornado kills four in Massachusetts

    On Wednesday, as many as seven tornadoes tore through Massachusetts resulting in the state’s first twister related deaths in sixteen years; the tornadoes touched down in the western and central part of the state, but hit Springfield, located ninety miles west of Boston, the hardest; more than forty people have been admitted to hospitals after sustaining injuries from the tornado and four people have been confirmed dead so far; emergency responders are currently picking through the wreckage to rescue any survivors trapped in the rubble

  • Ports unprepared for increase in Katrina-like storms

    A recent report by Stanford University researchers found that the majority of seaports around the world are unprepared for rising sea levels and increasingly violent storms; a majority of ports surveyed listed sea level rise and increasing extreme storms as some of their top concerns; only 6 percent of respondents said they have plans to build hurricane barriers in the next ten years, and less than 18 percent said they had plans to build dikes or other storm protection structures; to ease uncertainty among port authorities, researchers developed a computer model to provide cost estimates that take into account a port’s specific location as well as the cost of labor, materials, and equipment for fortifying a structure against rising sea levels

  • Former world leaders say global water crisis must be addressed

    In March 2008, the U.K. intelligence services, in a report to then-prime minister Gordon Brown, warned that the deteriorating fresh water situation around the world would soon lead not only to tensions over water between states, but to “water wars”; world leaders, at least former world leaders, agree that the global water situation is dire, and twenty of them, led by Bill Clinton, meet to discuss solutions

  • Human impact of rising oceans will extend well beyond coasts

    Identifying the human impact of rising sea levels is far more complex than just looking at coastal cities on a map; rather, estimates that are based on current, static population data can greatly misrepresent the true extent — and the pronounced variability — of the human toll of climate change; a new study focuses on four regions identified as highly susceptible to flooding: the tip of the Florida peninsula, coastal South Carolina, the northern New Jersey coastline, and the greater Sacramento region of northern California; the study finds that by 2030, more than nineteen million people will be affected by rising sea levels just in their four study areas

  • Germany to scrap nuclear power by 2022

    Germany yesterday announced plans to become the first major industrialized power to shut down all its nuclear plants in the wake of the disaster in Japan; phase-out due to be wrapped up by 2022; it means that the country will have to find the 22 percent of its electricity needs currently covered by nuclear reactors from another source; Monday decision is a U-turn for Chancellor Angela Merkel, and means that the current government has adopted the timetable for a nuclear phase-out set by the previous Social Democrat-Green coalition government a decade ago; it also cancels Merkel’s decision from November 2010 to extend the lifetime of Germany’s seventeen reactors by an average of twelve years, which would have kept them open until the mid-2030s

  • Global carbon emissions at record high

    Global carbon emissions are at their highest ever levels, increasing fears of a global temperature rise over the “dangerous” two degrees Celsius threshold; unpublished estimates from the International Energy Agency revealed that the world economy’s return to growth in 2010 coincided with a 1.6 gigaton rise in carbon dioxide emissions, the highest ever recorded jump

  • Global warming: Arctic access by land will diminish, but improve by sea

    Global warming over the next forty years will cut through Arctic transportation networks like a double-edged sword, limiting access in certain areas and vastly increasing it in others in absolute terms; winners are expected to be coastal communities, coastal resource-extraction operations, tourism, fishing, and shipping concerns; potential losers include inland mining and timber operations, inland oil and gas drilling, and smaller inland communities, often inhabited by indigenous peoples; Canada and Russia stand to lose the most winter-road potential as rising temperatures will prevent up to 400,000 square miles from hardening into potential roadways

  • More tornadoes headed to Joplin, Missouri

    As emergency responders pick through the wreckage from Sunday’s massive tornado in Joplin, Missouri, residents are preparing for another monstrous storm that could generate more deadly tornadoes; meteorologists anticipate that thunderstorms will hit Joplin once again on Tuesday night; rescue workers raced to sift through the rubble in search of survivors before the next storm hits; it is estimated that 30 percent of the city has been destroyed after the tornado carved a three-quarter mile wide path of destruction; so far officials have confirmed that at least 117 people are dead, more than 600 injured, and approximately 1,500 are still missing from one of the country’s deadliest tornadoes in over sixty years; initial projections rate the monstrous tornado as an EF-4 with wind speeds of 166 to 200 miles per hour; it is reported that the mile-wide funnel contained two cyclones inside; President Obama is currently overseas in the United Kingdom, but plans to visit Missouri this weekend after returning from Europe

  • China admits to critical flaws at world’s largest dam

    Last week, the Chinese government made a rare announcement and publicly admitted that there were critical problems at the Three Gorges dam, the world’s largest hydroelectric dam, lending support to the growing opposition to future dam projects; with the approval of Chinese Premier Wen Jiabao, the country’s second in command, last Thursday the State Council announced that the Three Gorges dam had been plagued by a series of problems “urgently in need of resolution”; problems include ecological deterioration, geological disasters, and the lingering uncertain status of more than one million people displaced by the dam; this is the first time such a high-ranking government official has publicly acknowledged the dam’s problems

  • Western states could face disastrous floods from record snowpacks

    Western states could soon face disastrous floods like the Midwest due to record snowpacks; heavy winter storms and an abnormally cold and wet spring have resulted in record snow levels for May in states across the west including Montano, New Mexico, Colorado, and California; officials worry that if June is particularly hot and sunny, the snow could melt too quickly and inundate the region’s rivers with torrents of water; officials are particularly concerned about flash floods as they can occur with little warning; officials are bracing for the worst holding emergency drills and releasing thousands of gallons of water to make room in reservoirs

  • Tornado kills at least 116 in Joplin, Missouri

    Residents and emergency responders are searching for survivors in Joplin, Missouri after a tornado tore through the town Sunday evening; the tornado tore a 6-mile-long, half-mile wide path through the middle of town; much of the city’s south side was leveled, with churches, schools, businesses, and homes reduced to ruins by winds of up to 165 mph; so far 116 people have been found dead, and officials expect the death toll to rise; officials have estimated 2,000 buildings were damaged; among the ruined buildings is St. John’s Regional Medical center, the city’s major hospital; the hospital was struck directly by the tornado and lost portions of its roof, façade, and windows; the Joplin twister was one of 68 reported tornadoes across seven Midwest states over the weekend

  • Hydropower gaining traction around the world

    As more nations turn to renewable energy sources, wind and solar have often grabbed all the attention, but hydropower has been steadily making quiet gains. While hydroelectricity is becoming more prevalent, its future is riddled with uncertainty and difficult questions; in 2008, hydroelectricity generated more than 250 billion kilowatthours of electricity, roughly 67 percent of all renewable energy produced that year; new dam projects are also generating a lot of criticism from environmentalists and local residents who worry about the people who will be displaced as well as the dams’ environmental impacts; ironically hydroelectric dams will be affected by climate change, the very thing it is designed to combat

  • Risk of wetland habitat loss in southern United States

    Between 1992 and 1997, more than 500,000 acres of wetlands were lost in the United States; 75 percent of those losses were attributed to development or agriculture; the greatest loss during this period occurred in the southern United States, with development as the main reason for wetland habitat loss; wetlands are important not only as a habitat for wild life, but as a line of defense against catastrophic floods and intense storms

  • Using river sediment to repair the coast

    The water of the Mississippi River swells beyond levees and flood-control barriers, flooding large areas, destroying costly infrastructure assets, and inflicting economic harms; not all is bad, though: large floods like the current one carry huge quantities of sediment that eventually deposit on the riverbed, making the river shallower, or are carried out to the Gulf of Mexico; the vast amount of water going south will replenish Louisiana’s coastal wetlands, and the sediment carried by the water will restore long stretches of eroding coastline and rebuild barrier islands in the Gulf
