Obama offers strategic redefinition, expansion of DHS mission
In July 2002, nearly a year before DHS was created under former president George W. Bush, a handful of advisers hastily drafted in private a 90-page national homeland security strategy; that document was later criticized for being partially responsible — by overemphasizing terrorism at the expense of natural disasters — for the Bush administration’s botched response to Hurricane Katrina; in October 2007 the Bush administration updated its homeland security strategy; the Obama administration has now revised and expanded Bush’s 2007 changes; the new strategy states that preventing terrorism remains the cornerstone of homeland security, but it expands the definition of homeland security to include other hazards, among them mass cyberattacks, pandemics, natural disasters, illegal trafficking, and transnational crime

Cold war offered odd benefit: it limited species invasions
During the cold war, when an Iron Curtain divided the European continent, there were few introduced bird species in Western Europe; following the collapse of the Soviet Union and the removal of the Iron Curtain, trade and the movement of people between east and west increased – and with it the introduction of non-native bird species; these non-native species do not have natural enemies in the local habitat, so they do damage to agriculture and domestic birds, and carry disease

Climate change experts argue for international geoengineering effort
Solar-radiation management (SRM) would involve releasing megatons of light-scattering aerosol particles in the upper atmosphere to reduce Earth’s absorption of solar energy, thereby cooling the planet; another technique would be to release particles of sea salt to make low-altitude clouds reflect more solar energy back into space; long-established estimates show that SRM could offset this century’s predicted global average temperature rise more than 100 times more cheaply than achieving the same cooling by cutting emissions

Haiti earthquake a reminder that disasters are preventable
While earthquakes are inevitable in earthquake zones, and hurricanes and tornadoes are inevitable under certain weather conditions — “there are no inevitable disasters,” a University of Colorado expert says; “There is no such thing as a natural disaster”; the scope of death and injury, the magnitude of damage to buildings and infrastructure, are the result not of nature – but of man-made decisions; what we see in Haiti is the result of decades of corrupt and ineffective Haitian governments, indifferent to the welfare of the Haitian people

Need seen for single U.S. disaster recovery agency
The Obama administration has launched a series of meetings around the country which bring together government officials and representatives of non-profit, volunteer, and faith-based organizations to identify and share best practices and innovations in the area of disaster recovery; insights gathered at these meetings and at other similar meetings will go into recommendations for improving disaster recover policy to be presented to the Obama administration in April

Experts: U.K. must act now to prepare for rising sea level
A joint study by the leading U.K. civil engineering and architectural associations says that steps must be taken now to protect coastal towns from rising sea levels; the reports says policy makes should consider three options for tackling rising sea level: “retreat” — moving critical infrastructure and housing to safer ground; “defend” — building town or city-wide sea defenses; and “attack” — extending the existing coastline and building out on to the water

Maximum height of extreme waves up dramatically in Pacific Northwest
A new assessment concludes that the highest waves in a “100-year event” along the Pacific Northwest’s coast may be as much as 46 feet, up from estimates of only 33 feet that were made as recently as 1996, and a 40 percent increase; the new findings raise special concerns for flooding, coastal erosion, and structural damage; “The Pacific Northwest has one of the strongest wave climates in the world, and the data clearly show that it’s getting even bigger,” says one of scientists involved

Haitian architects, urban planners say the need is to build a better Haiti
A group of Haitian architects, engineers, and urban planners has met every day since the devastating quake, discussing not how to rebuild the country, but how to start anew; they should start with the country’s building code; one high government official participating in the meetings says dismissively: “There is a two-page building code [in Haiti]… that nobody used”

Cities say new FEMA flood maps contain many errors
In 2004 the Federal Emergency Management Agency (FEMA) started the $200 million-per-year project as a way to utilize advances in mapping technology better to identify areas susceptible to flooding; FEMA officials say the new maps will allow for better zoning and help prevent future catastrophes like the June 2008 flood in Iowa, which caused an estimated $10 billion in damage; cities, developers, and residents say new FEMA flood plain maps are full of mistakes that could prove costly

Engineers urge overhaul of Haiti's archaic, anarchic building practices
In Haiti, the poorest country in the Western Hemisphere, building codes, if they even exist, exist on paper only; all governments in Haiti, including the present one, have been corrupt, predatory, and utterly indifferent to the welfare of the people; a recent OAS report detailed a litany of flaws in Haiti’s attitude to buildings: weak or missing reinforcement, structures on steep slopes with unstable foundations, inadequate or nonexistant inspections, poor designs, materials, and techniques; Kit Miyamoto, a California structural engineer who went to Haiti last week: “No code, no engineering, means death”

Army engineers: Haiti's bad roads not damaged by quake
Engineers from the U.S. Army Corps of Engineers say that many of Haiti’s roads are not any worse than they were before because they have always been in poor condition; 80 percent of the major destruction is around the city’s capital; 200 million cubic yards of debris will need to be removed from Port-au-Prince

Scientists: Only nukes can stop planet-threatening asteroids
A new report by the U.S. National Research Council (NRC) says that the United States is not doing enough to protect itself – and the world – from Near Earth Objects (NEOs); the panel says that the only hope humanity has to against the larger asteroids – those bigger than 1 km; if they hit Earth, they would release energies in the hundred-thousand-megaton range – is to use nuclear weapons to try and push them off course

Panel calls for global asteroid defense agency
Existing surveys are incapable of finding 90 percent of near-Earth asteroids that are 140 meters across or larger by 2020 — a goal set by the U.S. Congress in 2005; a panel of scientists recommends setting up an international body that would be prepared to spring into action and defend the planet if an asteroid is discovered on a likely impact course

More money needed to boost England's flood defenses
The U.K. floods of 2007 caused £3.2 billion in damage and recovery costs; U.K. Environment Agency (EA) says that there is a need to double the country’s investment in flood defenses to £1 billion a year by 2035 – or damages from future floods further - disruption, damage to infrastructure, and loss of business — could rise by 60 percent

Seabed cable signals to sense tsunamis
The current tsunami warning system relies on a global seismometer network to detect earthquakes that may indicate that a tsunami has formed; deep-ocean pressure sensors and coastal tide gauges are the only tools available to detect and measure an actual tsunami; the electric current induced in submarine cables may provide an additional way to confirm and track a tsunami; researchers suggest monitoring voltages changes across the vast network of communication cables on the seabed to enhance the current tsunami warning system

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.
