New Army Corps of Engineers' policy instructs project designers to take rising sea levels into account
The Army Corps will from now on incorporate estimates of rising sea levels in all its plans for flood control, navigation, and other water projects; the corps has had a planning policy for rising sea levels since 1986, but the instructions were less than a page long, buried in a 1,000-page document and largely ignored; the new policy is articulated in a 44-page stand-alone document

U.K. agency to increase flood protection
The number of properties in England and Wales at significant risk of flooding could increase from 570,000 in 2009 to over 900,000 by 2035 at current levels of flood-defense investment; the Environment Agency says it is planning for the long haul, saying it is already planning to manage a predicted 1 meter rise in sea levels, and a predicted 10 percent increase in wave heights and wind speeds, both of which will increase the threat from coastal surges

Army Corps of Engineers in a $1 billion project to protect New Orleans' flank
The West Bank area of New Orleans is primed for growth, but experts warn that developers and residents should be aware of a problem: the bowl-shaped area is considered by experts as perhaps the city’s most vulnerable flank;’

U.S. Congress holds hearings on geoengineering
Geoengineering — the effort to design systems which would change the world’s climate — was once a fringe phenomenon; it has been moving into the mainstream, though, as more and more scientists are growing increasingly concerned that, even if we commit to cutting emissions drastically, we have already waited too long, and that by the time we actually reduce emissions, enough greenhouse gases will have accumulated to cause serious climate disasters

Using technology to prepare vulnerable communities for earthquakes
Satellite photographs and remotely measured surface heights from NASA will be used for assessing the vulnerability of natural slopes to earthquake-induced landslides; a team of U.K. scientists will also build up a database of slopes that failed in earthquakes; the information collected will include local geology, vegetation, slope angle, distance from the fault, and the amount of ground shaking

African desert rift confirmed as new ocean is forming
Geologists show that seafloor dynamics are at work in splitting African continent; scientists from several countries have confirmed that the volcanic processes at work beneath the Ethiopian rift are nearly identical to those at the bottom of the world’s oceans, and the rift is indeed likely the beginning of a new sea

Earthquake-proof airport terminal in Istanbul airport
Large swaths of Turkey are earthquake prone; the 1999 Kocaeli earthquake, for example, killed 17,000 people, injured 50,000, and destroyed 27,000 buildings, leaving 500,000 homeless; estimates of property losses range from $3 billion to $6.5 billion; engineers claim they have made the terminal at Istanbul Sabiha Gokcen International Airport earthquake-proof

Louisiana levee to use stabilizing fabric
The 1,600-foot earthen levee, which runs south from the Old Estelle Pump Station, has failed twice, once in the early 1990s and again in 2007 when two sections totaling 600 feet long slumped badly; Army Corps of Engineers will use geotextile fabric to stabilize known trouble spots before raising the levee from 10 feet to 14.5 feet

Despite concerns, development still heads to the coast
Many scientists predict that by 2100, sea levels would rise more than one meter; still, Florida has opened more vulnerable areas along the Atlantic coast to construction — and has done so more than any other state

Aussies worry about rising sea levels

Cosmic entropy could be 100 times greater than previously thought
Entropy increases as the number of ways the system can be arranged microscopically without changing the external appearance increases; new study shows that cosmic entropy is a 100 times greater than earlier estimates; the entropy of the universe must be below the maximum theoretical value or life and other complex phenomena will cease to exist; as the entropy gradually increases it will eventually approach the theoretical maximum, a state many physicists have called the heat death of the universe; the new study thus shows that our universe is closer to its death than previously thought

Without water reform Asia will face food shortage by 2050
There are three options for meeting the food needs of Asia’s population, which will expand by one-and-a-half billion people over the next forty years: The first is to import large quantities of cereals from other regions; the second to improve and expand rainfed agriculture; and the third to focus on irrigated farmlands

New Bay Bridge span designed to endure major quake
Twenty years ago a 250-ton section of the Bay Bridge fell into the water as a result of a 6.9 magnitude earthquake; the new bridge design will be able to withstand the largest plausible earthquake to occur within a 1,500-year period

The long view
Protecting the U.S. power grid
The U.S. power grid is made up of complex and expensive system components, which are owned by utilities ranging from small municipalities to large national corporations spanning multiple states. A National Academy of Sciences report estimates that a worst-case geomagnetic storm could have an economic impact of $1 trillion to $2 trillion in the first year, which is twenty times the damage caused by a Katrina-class hurricane.
More than 143 million Americans at risk from earthquakes
More than 143 million Americans living in the forty-eight contiguous states are exposed to potentially damaging ground shaking from earthquakes, with as many as twenty-eight million people in the highest hazard zones likely to experience strong shaking during their lifetime, according to new research. The research puts the average long-term value of building losses from earthquakes at $4.5 billion per year, with roughly 80 percent of losses attributed to California, Oregon, and Washington. By comparison, FEMA estimated in 1994 that seventy-five million Americans in thirty-nine states were at risk from earthquakes. In the highest hazard zones, the researchers identified more than 6,000 fire stations, more than 800 hospitals, and nearly 20,000 public and private schools that may be exposed to strong ground motion from earthquakes.
A large Ventura Fault quake could trigger a tsunami
Earthquake experts had not foreseen the 2011 magnitude-9 Japan earthquake occurring where it did, so soon after the disaster, scientists in Southern California began asking themselves, “What are the big things we’re missing?” For decades, seismic experts believed the Ventura fault posed only a minor to moderate threat, but new research suggests that a magnitude-8 earthquake could occur on the fault roughly every 400 to 2,400 years. The newly discovered risk may even be more damaging than a large earthquake occurring on the San Andreas Fault, which has long been considered the state’s most dangerous. Unlike the Ventura fault, the San Andreas Fault is so far inland in Southern California, that it does not pose a tsunami risk. A large earthquake on the Ventura fault, however, could create a tsunami that would begin “in the Santa Barbara Channel area, and would affect the coastline … of Santa Barbara, Carpinteria, down through the Santa Monica area and further south.”
Coastal communities can lower flood insurance rates by addressing sea-level rise
City leaders and property developers in Tampa Bay are urging coastal communities to prepare today for sea-level rise and future floods in order to keep flood insurance rates low in the future. FEMA, which administers the National Flood Insurance Program(NFIP), is increasing flood insurance premiums across the country, partly to offset losses from recent disasters such as hurricanes Katrina and Sandy. Cities can reduce insurance premiums for nearly all residents who carry flood coverage by improving storm-water drainage, updating building codes to reflect projected rise in sea-levels, moving homes out of potentially hazardous areas, and effectively informing residents about storm danger and evacuation routes.
California drought highlights the state’s economic divide
As much of Southern California enters into the spring and warmer temperatures, the effects of California’s historic drought begin to manifest themselves in the daily lives of residents, highlighting the economic inequality in the ways people cope. Following Governor Jerry Brown’s (D) unprecedented water rationing regulations,wealthier Californians weigh on which day of the week no longer to water their grass, while those less fortunate are now choosing which days they skip a bath.
