USGS sampling water in Hurricane Sandy’s aftermath to ensure public health
Excessive nutrients in U.S. rivers, streams, and coastal areas are a major issue for water managers, because they cause algal blooms that increase costs to treat drinking water, limit recreational activities, and threaten valuable commercial and recreational fisheries; U.S. Geological Survey crews are sampling water for nutrients, sediment, and pesticides to document water quality in areas affected by the hurricane

The science of hurricanes is imprecise, but delayed decisions on preparedness and adaptation may cost lives
It is difficult to tie a specific storm like Hurricane Sandy to the phenomenon of climate change; a professor of civil and environmental engineering says that this is a perfect example where the climate science may not yet be as precise as we would like, but important preparedness decisions still need to be made with some urgency; this is also an example where delayed decisions on preparedness and adaptation may cost human lives, destroy critical infrastructures, and damage economies; the importance of adaptation and preparedness in this context cannot be overstated

California worried about its own extreme weather
California will not see a superstorm like Hurricane Sandy because the Pacific Ocean is too cold to feed that kind of weather system, but researchers monitoring precipitation and snowpack say weather can have comparable effects

Sandy in perspective
Hurricane Sandy has left death and destruction in its path, and it broke a few records, but there were worse hurricanes; since 1900, 242 hurricanes have hit the United States; if Sandy causes $20 billion in damage, in 2012 dollars, it would rank as the seventeenth most damaging hurricane or tropical storm out of these 242; the Great Miami Hurricane of 1926 tops the list; Hurricane Katrina ranks fourth; from August 1954 through August 1955, the East Coast saw three different storms make landfall — Carol, Hazel, and Diane; each, in 2012, would have caused about twice as much damage as Sandy

Sea levels are rising ahead of predictions; scientists explain why
The last official Intergovernmental Panel on Climate Change (IPCC) report in 2007 projected a global sea level rise between 0.2 and 0.5 meters by the year 2100; current sea-level rise measurements meet or exceed the high end of that range and suggest a rise of one meter or more by the end of the century; scientists meeting next week at the Geological Society of America annual meeting will discuss whether estimates of the rate of future sea-level rise are too low

Experts: German nuclear exit offers economic, environmental benefits
Following the accident at the Fukushima Daiichi Nuclear Power Station in 2011, the German government took the nation’s eight oldest reactors offline immediately and passed legislation which will close the last nuclear power plant by 2022; this nuclear phase-out had overwhelming political support in Germany; elsewhere, many saw it as “panic politics”; a new collection of studies shows that the nuclear shutdown and an accompanying move toward renewable energy are already yielding measurable economic and environmental benefits

Rising sea levels make NYC vulnerable to more frequent, more intense floods
Scientists say that Hurricane Sandy has forced a recognition on New York City and on other coastal communities: the steady rise in sea levels means not only more floods, but more frequent and more devastating floods; three of the top 10 highest floods at the Battery since 1900 happened in the last two and a half years; after rising roughly an inch per decade in the last century, coastal waters in New York are expected to climb as fast as six inches per decade, or two feet by midcentury; the city is exploring a $10 billion system of surge barriers and huge sea gates

Study connects burning fossil fuels to sea level rise
A study has found that burning all the Earth’s reserves of fossil fuels could cause sea levels to rise by as much as five meters — with levels continuing to rise for typically 500 years after carbon dioxide emissions ceased

Leading U.S., U.K. scientists condemn conviction of Italian earthquake scientists
A judge in Italy last week sentenced six Italian seismologists and a former government official to six years in prison over the deadly 6 April 2009 earthquake in L’Aquila. The seven defendants were found guilty of manslaughter; Ralph J. Cicerone, president of the U.S. National Academy of Sciences, and Sir Paul Nurse, president of the U.K. Royal Society, issued the following statement

Researchers invent safe wireless vehicle charging technology
Researchers have invented a safe, efficient technology wirelessly to charge electric vehicles using “remote magnetic gears” — a rotating base magnet driven by electricity from the grid, and a second located within the car — and successfully tested it on campus service vehicles

USGS: Sandy will erode many Atlantic Coast beaches
Nearly three quarters of the coast along the Delmarva Peninsula is very likely to experience beach and dune erosion as Hurricane Sandy makes landfall, while overwash is expected along nearly half of the shoreline; the predictions of coastal change for the Delaware, Maryland, and Virginia peninsula is part of a larger assessment of probable coastal change released by the U.S. Geological Survey (USGS)

Hurricanes will test Florida buildings, built under new, post-Wilma building codes
In 2005 Hurricane Wilma was responsible for five deaths and millions of dollars worth of damage in Florida; building codes in the state were updated, and experts predict that these new buildings, most of which were designed with wind-tunnel testing, should perform well in all but the most severe conditions

Human activity can trigger an earthquake
Earthquakes occur when tectonic plates try to move past each other, and the friction between them holds them in place; the friction creates energy which builds up, and when the plates move past each other, the energy is released, triggering an earthquake; fracturing increases the fluid pressure inside faults; this increased pressure, in turn, lowers the stress threshold for triggering an earthquake enough for one to take place

Thawing permafrost to release nitrogen, carbon – doubling the amount of carbon in the atmosphere today
As much as forty-four billion tons of nitrogen and 850 billion tons of carbon stored in arctic permafrost, or frozen ground, could be released into the environment as the region begins to thaw over the next century as a result of a warmer planet; for context, this is roughly the amount of carbon stored in the atmosphere today
