Florida moves to protect coastal roads from sea level rise
Alton Road is a few blocks west of the Atlantic Ocean, and is Miami Beach’s lowest point, at 2.8 feet above sea level. Trouble is, as a result of sea level rise, inundation tide now routinely reaches 3.4 feet above sea level. Geologist have long warned of the impact sea level rise would have on Florida’s coastal infrastructure, and they view Alto Road as Ground Zero, saying that at some point in the near future, water from flooding will not recede. The Florida Department of Transportation (FDOT) is taking steps to protect coastal transportation infrastructure from sea level rise.

New York public transit systems preparing for sea-level rise
The Metropolitan Transportation Authority (MTA), which operates many New York state public transit lines, is beginning measures to factor for future sea-level rises within its projected five-year capital plans.Tobey Ritz, chief engineer of capital engineering at Metro-North, said: “It’s not so much for us to pick which study [of sea-level rise] is right, but to look at the entire range [of sea-level rise predictions], look at the time frames that are predicted and then consider when is the right time to act.”

Intelligent urban planning to drive climate change solutions
A leaked report from the Intergovernmental Panel on Climate Change (IPCC) suggests that intelligent urban planning and investment in public transportation, especially in developing countries, could be the key factors in lower greenhouse gas emissions and reversing the effects of climate change.

Major step toward stronger encryption technology announced
Researchers the other day announced the first successful trial of Quantum Key Distribution (QKD) technology over a live “lit” fiber network. The trial paves the way for more advanced research into QKD, the next frontier of data encryption technology, which will deliver even greater levels of network security.

Odds of storm waters overflowing Manhattan seawall up 20-fold, new study says
Maximum water levels in New York harbor during major storms have risen by nearly two and a half feet since the mid-1800s, making the chances of water overtopping the Manhattan seawall now at least twenty times greater than they were 170 years ago, according to a new study. Whereas sea-level rise, which is occurring globally, has raised water levels along New York harbor by nearly a foot and a half since the mid-nineteenth century, the research shows that the maximum height of the city’s “once-in-10-years” storm tide has grown additionally by almost a foot in that same period.

Dams will not reduce flow of sand to Mississippi River Delta
The wetlands of the Mississippi River Delta are slowly sinking and rapidly eroding, but new research has found the river’s supply of sand — the material engineers most need to rebuild the delta — will stay constant for centuries. The new study is encouraging news for scientists and government officials who are working to shore up southeastern Louisiana’s rapidly disappearing wetlands.

Helping Kansas counties deal with deficient bridges
Seventy-eight of the 105 counties in the state of Kansas have bridges on low-volume rural roads in dire need of repair, replacement, or removal. With an estimated cost of $150,000 per bridge — and nearly 1,000 bridges across the state in the structurally deficient or functionally obsolete categories — replacement bridges are an expensive proposition. A new study offers a way to determine which bridges should be repaired, and which should be closed.

Dynamic atolls give hope that Pacific Islands can defy sea rise
It is widely predicted that low-lying coral reef islands will drown as a result of sea-level rise, leaving their populations as environmental refugees. New evidence, however, now suggests that these small islands will be more resilient to sea-level rise than we thought. The new findings suggest that, rather than being passive lumps of rock that will be swamped by rising seas and eroded by storms, the islands are dynamic structures that can move and even grow in response to changing seas. Although the islands may survive into the future, the changes could still affect issues like fresh water and agriculture, potentially making life on these islands much more difficult than it is today.

More, bigger wildfires burning western U.S.
Wildfires across the western United States have been getting bigger and more frequent over the last thirty years — a trend that could continue as climate change causes temperatures to rise and drought to become more severe in the coming decades, according to new research.

Long-term predictions for Miami sea level rise could be available soon
Researchers say that Miami could know as early as 2020 how high sea levels will rise into the next century. Scientists conclude that sea level rise is one of the most certain consequences of climate change. The speed and long-term height of that rise, however, are unknown. Some researchers believe that sea level rise is accelerating, some suggest the rate is holding steady, while others say it is decelerating. Scientists say that numbers should continue to be crunched every decade, creating more certainty in long-term planning — and helping develop solutions for a changing planet.

How building codes save homes from cyclones, and how they don’t
During Queensland’s preparations for Severe Tropical Cyclone Ita, Queensland Premier Campbell Newman advised residents who lived in older houses (those built before 1985) to evacuate their homes as they were not likely to stand up to the storm’s destructive winds. That was the year that building regulations changed to require new houses in cyclone-prone areas to be able to withstand higher winds. But how were these regulations determined, what do they mean for modern homes, and why do regulators always seem to wait until after a severe storm before updating the codes?

West Point wins Cyber Defense Exercise, launches Army Cyber Institute
The U.S. Military Academy at West Point has won the annual Cyber Defense Exercise (CDX) which brought together senior cadets from the five service academies for a 4-day battle to test their cybersecurity skills against the National Security Agency’s (NSA) top information assurance professionals. West Point’s win comes just as the academy announced plans for its Army Cyber Institute(ACI), intended to develop elite cyber troops for the Pentagon.

How the Heartbleed bug reveals a flaw in online security
The Heartbleed bug – which infects an extremely widespread piece of software called OpenSSL — has potentially exposed the personal and financial data of millions of people stored online has also exposed a hole in the way some security software is developed and used. The Heartbleed bug represents a massive failure of risk analysis. OpenSSL’s design prioritizes performance over security, which probably no longer makes sense. But the bigger failure in risk analysis lies with the organizations which use OpenSSL and other software like it. A huge array of businesses, including very large IT businesses with the resources to act, did not take any steps in advance to mitigate the losses. They could have chosen to fund a replacement using more secure technologies, and they could have chosen to fund better auditing and testing of OpenSSL so that bugs such as this are caught before deployment. They didn’t do either, so they — and now we — wear the consequences, which likely far exceed the costs of mitigation.

California implements earthquakes’ lessons
In California, government engineers study structures that did not survive the earthquake, with plans to make improvements to building codes. The most important code changes tend to occur because earthquakes uncover weaknesses in contemporary construction standards.”Every time the earth shakes there’s something a little different about it,” says one official.

Feds struggle to plug power grid security holes
Many of the current vulnerabilities in the power grid are attributable to newly adopted smart-grid technology, which allows operators to transmit energy from a diverse pool of resources. Smart-grid technology relies on devices in remote locations which constantly communicate with substations, those access points can be compromised by hackers.
