NIST releases draft Community Resilience Planning Guide for public review
Over the last four years, the United States experienced forty-two extreme weather events which caused at least $1 billion in damage, for a total cost of about $227 billion and 1,286 lives lost. In all, there were 334 major disaster declarations in the United States between 2010 and 2014. The United States experienced about 500 natural disasters between 1994 and 2013, ranking second globally, behind China. The ten deadliest of these U.S. disasters killed more than 4,000 people. NIST issued a draft guide to help communities plan for and act to keep windstorms, floods, earthquakes, sea-level rise, industrial mishaps, and other hazards from inflicting disastrous consequences.

Web app helps Miami residents visualize how sea level rise affects their homes
Researchers have developed a web app, known as the Sea Level Rise Toolbox, which helps Miami-Dade residents visualize the possible impact of rising seas in South Florida on their neighborhoods. The Web app, using elevation data from the Google Elevation Service, and based on sea level rise calculations created by Peter Harlem, a scientist at FIU’s Geographic Information Systems (GIS) Center, is an interactive sea-level rise viewer where users can enter an address to visualize how up to a 6-foot rise in sea level may affect Miami-Dade County neighborhoods.

Nepal would have benefitted from a seismic early-warning system: Experts
As far back as the thirteenth century, Nepal experienced a major earthquake every seventy-five years or so, and just like the recent magnitude 7.8 quake, no one has been able to predict exactly when the next quake will strike. If forecasters are unable to anticipate quakes days or weeks ahead, then residents of earthquake prone areas may have to rely on early-warning systems which are able to provide a few seconds notice before an earthquake strikes. Earthquake early-warning systems have been deployed in a few seismic hot zones including Japan, Mexico, and California.

Israel worries about its own Big One
The magnitude 7.8 earthquake that struck Nepal, leaving more than 4,000 people dead, has alerted earthquake experts in Israel about the country’s own seismic risk, which could result in a large quake months or a few years from now. Israel, the Palestinian territories, and Jordan are sitting on a major fault line which constitutes “a real, as well as a current, threat to the safety, social integrity, and economic well-being of the people in the region,” reads a 2007 earthquake report.

Preventing a Fukushima-like disaster in Europe
In 2005, Europe was exposed to a potential risk of a nuclear disaster caused by the flooding of the Loviisa nuclear power plant in Finland. Sea levels rose by 1.73 meter above normal levels, due to a storm. As a result, flood defenses have been reinforced. Floods are likely to occur more frequently than anticipated when nuclear power plants where built, due to climate change. Improved safety management and further collaboration between experts are required to minimize the risk of flooding at coastal nuclear plants in Europe.

Flood disaster risk is more complex than expected
Researchers have shed further light on the complex issue of flood risk, with the latest findings showing the potential for flood risk to both increase and decrease in the same geographic area. There are two major types of floods from rivers: one is caused by heavy rain sustained over long periods of time that might affect large catchments over a wide geographic area; the other is caused by short but extremely heavy rain events, which might only last for thirty minutes and is usually localized, often called “flash flooding.” “At the global scale we’re increasingly confident that flood risk will change, because a warming atmosphere means more heavy rain. However, for any individual location the changes to flood risk will depend on each region’s rainfall patterns. Under certain circumstances the flood risk may actually decrease,” says one researcher.

More than half of hot extremes are the result of climate change
Torrential rains and blazing heat have been mentioned even in the oldest manuscripts and have always been part of the climate. A substantial proportion of today’s extreme high-temperature and heavy rainfall events, however, can be attributed to the observed warming. Scientists say it would be wrong to conclude that climate change has no effect on the frequency of such events based simply on the fact that weather extremes existed in the past. However, it is also clear that what is often referred to as “global weirding,” or the idea that all weather phenomena are becoming increasingly extreme, falls short.

Miami Beach luxury real estate market is booming in the face of rising sea levels
By 2100, sea levels could rise by as much as six feet. Miami Beach, with its dense population and low altitude, is on the list of U.S. cities at greatest risk. This recognition has not slowed down the region’s luxury real estate market. To help drain city streets during high tides and floods, Miami Beach is installing an eighty pumping system units expected to cost between $300 and $500 million.Scientists are skeptical of plans to solve the city’s flood and tackle sea level rise problem with pumps, saying the only solution is rebuilding and retrofitting some city infrastructure at higher levels – and moving some neighborhood inland. “If you spend [the money] on the easy stuff, you’re not going to have any money left for the hard stuff,” says one geologist. “So my concern is the longer-term sea level rise that’s going to get real expensive — and if we’re all broke because we blew all that money saving a few places that should have been moved.”

As climate warms, vast amounts of carbon may be release from long-frozen Arctic soils
Scientists estimate there is more than ten times the amount of carbon in the Arctic soil than has been put into the atmosphere by burning fossil fuels since the start of the Industrial Revolution. To look at it another way, scientists estimate there is two and a half times more carbon locked away in the Arctic deep freezer than there is in the atmosphere today. Now, with a warming climate, that deep freezer is beginning to thaw and that long-frozen carbon is beginning to be released into the environment.

Nepal shows its vulnerability after devastating earthquake
For some time scientists have realized that the Kathmandu valley is one of the most dangerous places in the world, in terms of earthquake risk. And now a combination of high seismic activity at the front of the Tibetan plateau, poor building standards, and haphazard urbanization have come together with fatal consequences.

Oklahoma scientists warn about fracking-induced earthquakes
Using stronger language than in the past, the Oklahoma Geological Survey (OGS) announced on Tuesday that the state’s ongoing waves of earthquakes are “very unlikely to represent a naturally occurring process.” The OGS says that fracking was likely a cause for the increased seismicity. The state’s seismicity rate in 2013 was seventy times greater than the rate before 2008, and rapidly grew to about 600 times greater today, according to the OGS. The average oil well in Oklahoma requires about ten barrels of saltwater to be injected for every barrel of oil that can be pumped out.

Building healthier communities essential for recovering from disasters
U.S. communities and federal agencies should more intentionally seek to create healthier communities during disaster preparation and recovery efforts — something that rarely happens now, says a new report from the Institute of Medicine. By adding a health “lens” to planning and recovery, a community can both mitigate the health damage caused by disasters and recover in ways that make the community healthier and more resilient than it was before.

Climate change will worsen natural catastrophes’ impact on corporate creditworthiness: S&P
Generally, companies have so far managed to mitigate the effects of natural catastrophes through liquidity management, insurance protection, natural disaster risk management, and post-event recovery measures. The more frequent and extreme climatic events many scientists predict, however, could adversely affect companies’ credit profiles in the future. Standard & Poor’s says that greater disclosure of firms’ exposure to extreme natural catastrophes should encourage them to bolster their resilience to these events and thereby aid transparency.

U.S. action on climate change hobbled by economics and politics, not divided science: Study
The U.S. Congress successfully hears the “supermajority” consensus on the reality and causes of climate change, according to new research, which analyzed 1,350 testimonies from 253 relevant congressional hearings from 1969 to 2007. Among expert witnesses who expressed a view, 86 percent say that global warming and climate change is happening and 78 percent say it is caused by human activity. Under Republican-controlled Congresses, a three-quarter supermajority of scientists say that global warming and climate change are real and anthropogenic. Most significant of all, 95 percent of scientists giving testimonies support action to combat it. “Different perceptions and claims among lawmakers are a major hurdle to agreeing on action to address global warming and these were thought to simply reflect scientific uncertainty,” says one of the authors. “However, our findings show that congressional testimonies are in fact consistent with agreement in the climate science community and that the sources of controversies must lie elsewhere.”

New insights on man-made earthquakes
Earthquake activity has sharply increased since 2009 in the central and eastern United States. The increase has been linked to industrial operations that dispose of wastewater by injecting it into deep wells. Significant strides in science have been made to better understand potential ground shaking from induced earthquakes, which are earthquakes triggered by man-made practices.

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.
