Young students compete at the Sea Level Measurement Device Design competition
Global warming is bringing about a rise in the mean sea level, and this increases the risk of coastal flooding brought by storm surges during the passage of tropical cyclones. Two-hundred young students – from 4th grade to junior high — from twenty-five primary, secondary, and international schools designed and produced sea level measurement devices to compete for various prizes in the Sea Level Measurement Device Design Competition held last Sunday at the University of Hong Kong.

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.

U.S. must invest in energy infrastructure to upgrade outdates systems
Energy Secretary Ernest Moniz is calling for a renewed focus on U.S. energy infrastructure, saying new and improved oil pipeline projects are just a portion of a long list of work needed to modernize the country’s outdated system for transporting oil, natural gas, and electricity.In the government’s first Quadrennial Energy Review (QER), an almost 500-page analysis released last week, Moniz calls for building new pipelines, repairing old ones, and insulating electric grids and transformers from storms and terrorist attacks.”It is the right time, maybe it’s a little after the right time, for us to make these kind of investments in energy infrastructure,” he said.

Disaster and recovery: The unexpected shall come to be expected
In the days following the Nepal earthquake, the media has been focusing on the heart-wrenching human interest and hero-tragedy stories, but what must be emphasized is that this disaster was anticipated. More importantly, we now have the tools and building technologies to mitigate the impact of even major earthquakes. The frequency of earthquakes has not changed over the past few million years, but now millions of people live in vulnerable situations. The unexpected must come to be expected. Much-needed humanitarian assistance must transition into long-term development efforts. Simply put, instilling a culture of disaster risk reduction, investing in hazard mitigation, building as best as we can, and retrofitting what remains, will save lives.

Deepwater Horizon consequences continues to plague Gulf Coast communities
Five years after the worst environmental disaster in U.S. history, communities along the Gulf of Mexico continue to struggle with the aftermath of the Deepwater Horizon oil spill, according to researchers. While most of the nation’s attention continues to focus on the environmental and financial toll of the spill that killed eleven workers and flooded Gulf waters with millions of gallons of oil, the less obvious consequences, including those related to public health, may prove the most long-lasting, the researchers say.

Nano-coated mesh captures oil but lets water through
The unassuming piece of stainless steel mesh does not look like a very big deal, but it could make a big difference for future environmental cleanups. Water passes through the mesh but oil does not, thanks to a nearly invisible oil-repelling coating on its surface. In tests, researchers mixed water with oil and poured the mixture onto the mesh. The water filtered through the mesh to land in a beaker below. The oil collected on top of the mesh, and rolled off easily into a separate beaker when the mesh was tilted. The nano-coated mesh could clean oil spills for less than $1 per square foot.

Aquifer Storage and Recovery should be phased in to reverse Everglades decline
The aquifer storage and recovery (ASR) is a key component in the Central Everglades Restoration Plan (CERP), a joint state-federal effort to reverse the decline of the Everglades ecosystem. CERP aims to “get the water right” by improving the quantity, timing, and distribution of water flows. Over a century of canal drainage and water management has led to extensive losses of natural water storage, leaving the Everglades in critical need of new storage. Although uncertainties about ecological impacts are too great to justify near-term, large-scale implementation of the ASR in the Everglades, the ASR could be phased in to answer several important scientific questions and provide some early restoration benefits, says a report from the National Research Council (NRC).

U Oregon expands role in Pacific Northwest earthquake early warning system
The University of Oregon will soon be playing an active role in preparing West Coast residents for the next magnitude 9 earthquake. Working in cooperation with the Pacific Northwest Seismic Network (PNSN), the UO will maintain fifteen seismometers previously owned by the National Science Foundation (NSF). The seismic network is a cooperative between the UO and the University of Washington, and is a key player in the development and testing of a West Coast earthquake early warning system. The recent passage of Oregon Senate Bill 5543, which was signed 30 March by Gov. Kate Brown, paved the way for the state of Oregon to acquire the seismometers with a one-time appropriation of $670,000.

Resilient rivers respond quickly to dam removal
More than 1,000 dams have been removed across the United States because of safety concerns, sediment buildup, inefficiency, or having otherwise outlived usefulness. A paper published the other day finds that rivers are resilient and respond relatively quickly after a dam is removed. Studies show that most river channels stabilize within months or years, not decades, particularly when dams are removed rapidly.

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.

Israel’s navy protects more than the country’s coast
Cyber warriors working for Israel’s navy are constantly engaged in protecting against intense cyber intrusions which targets the country’s digital infrastructure, according to a senior navy source. “The navy understands that cyber conflicts are wars in their own right, beyond conventional conflicts that we have grown accustomed to. In cyber war, one can engage without firing a single bullet. Attacks can come before a conventional war. There are no official cease-fires. It goes on all of the time,” the source said.

Water scarcity increase Middle East instability
At least1.6 billion people worldwide face water scarcity because their countries lack the necessary infrastructure to move water from rivers and aquifers. In the Middle East, this lack of water infrastructure combines with the effects of global warming — including prolonged in droughts — to make the entire region politically and economically unstable. Food supplies are diminished as farmers find it difficult to find water for crops, and even basic sanitary requirements are not met due to poor access to clean water, thus increasing the spread of disease.

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.

Safety procedures have not kept up with new, deeper offshore oil drilling operations
Just five years after the BP Deepwater Horizon oil spill disaster, which leaked roughly 134 million gallons of oil into the Gulf of Mexico, federal agencies have approved even deeper series of next-generation wells, which critics cite as too new to be properly regulated. Concerned scientists and industry officials are arguing that the recently allowed wells have not yet developed proper corresponding safety procedures to prevent a disaster similar, or worse, than the one which befell the Macondo well.
