Resilience and adaptation strategies can address the impacts of climate change
By the end of this century, Chicago could face the kind of searing summer heat that Las Vegas sees now. Phoenix could hit 110 degrees, 60 or more days a year. That’s not wild speculation. It’s the official position of 13 federal agencies on climate change, released late last year with a warning: Local governments need to do more to prepare. Every road they build, every storm drain they put in, will have to hold up under conditions that modern civilization has never seen. How do you plan for that? Researchers at RAND have been working on that problem for a while now.

Simulating forest and fire dynamics to understand area burn of future wildfires
Climate change and wildfire – it’s a combustible mix with costly devastation and deadly consequences. With a goal of understanding the link between the two variables, researchers over the years have studied the effects of climate and wildfire interactions in the Sierra Nevada mountain range. That research has evolved into learning about the distribution of trees, the extent of forest cover and carbon dynamics.

Long-distance earthquake detection
In traditional seismology, researchers studying how the earth moves in the moments before, during, and after an earthquake rely on sensors that cost tens of thousands of dollars to make and install underground. Now researchers have figured out a way to overcome these hurdles by turning parts of a 13,000-mile-long testbed of “dark fiber,” unused fiber-optic cable, owned by the DOE Energy Sciences Network (ESnet), into a highly sensitive seismic activity sensor that could potentially augment the performance of earthquake early warning systems currently being developed in the western United States.

L.A. showcases quake alert system
California is earthquake country, and residents of Los Angeles can now get some critical warning, when conditions are right, after a quake has started and seismic waves are heading their way. The long-delayed system, called ShakeAlertLA, is the first of its kind in the United States.

Marine organisms as detectors of enemy undersea activity
Goliath grouper, black sea bass, and snapping shrimp, along with bioluminescent plankton and other microorganisms, are set to be the unlikely additions to protecting U.S. assets. Researchers are developing new types of sensor systems that detect and record the behaviors of these marine organisms and interpret them to identify, characterize, and report on the presence of manned and unmanned underwater vehicles operating in strategic waters. The incorporation of biological signals will extend the range, lifetime, and performance of undersea surveillance technologies in strategic waters.

And now, land may be sinking
In the coming decades, cities and towns up and down the eastern seaboard will have to come to terms with the impact of rising sea level due to climate change. A new study, however, is suggesting that rising sea levels may be only part of the picture — because the land along the coast is also sinking.

Rising seas disrupt local economies
Impacts from climate change are not always easy to see. But for many local businesses in coastal communities across the United States, the evidence is right outside their doors – or in their parking lots. High-tide flooding resulting from climate change is already disrupting the economy of Annapolis, Maryland. As sea levels rise, the impacts are expected to get worse for coastal communities.

Huawei espionage arrests in Poland: A wake-up call to Europe
U.S. and European intelligence services have been warning that Huawei, a jewel in the crown of the China’s growing technology industry, cannot be trusted in its protestations that it does not cooperate with the country’s intelligence agencies, or that it respects the rule of law and the intellectual property of its competitors. European governments should exclude Huawei from their telecommunications infrastructure before the company becomes too enmeshed in the continent’s 5G systems to be fully, securely, and painlessly removed at a later date. Failure to do so would give China truly unprecedented tools to corrupt, influence, and subvert Western democracies and the rule of law that is so vital to their continued health and the health of the post-War international system.

Keeping the lights on during and after a disaster
The threat of an inevitable earthquake is the uncomfortable truth we all face in the Cascadia Subduction Zone, which stretches from Alaska to California. Because the last major earthquake in the area was in the 1700s, our infrastructure developed without an appreciation and understanding of earthquake resilience. That means the next major earthquake will likely devastate our buildings, roads, bridges, and utility providers, posing immediate risks for the health and safety of those who live in the region. And later, there will be long-term economic aftershocks.

Using data utilization to augment community resilience, disaster response
A civil engineering who researches resilience against extreme events and natural hazards is responding to lessons learned from California’s deadly Camp Fire by outlining how to utilize the power of data to improve disaster response and minimize economic loss and human harm in similar events.

Paradigm shift needed for making bridges tsunami-resistant
Over the past fifteen years, big earthquakes whose epicenters were in the ocean off the coasts of Japan and Indonesia have caused tsunamis that killed more than 250,000 people and caused more than $200 billion in damage. The damage includes washing away or otherwise dislodging hundreds of bridges, emphasizing the need to better understand the wave impacts’ underlying physics. Researchers argue in a new study that a paradigm shift is needed for assessing bridges’ tsunami risk.

Lawmakers tell Pentagon to redo climate change report
Earlier this month, the Pentagon, in compliance with a congressional mandate, released a landmark report which identified the 79 American military installations most vulnerable to the “effects of a changing climate.” Several Democrats on the House Armed Services Committee welcomed the report – but at the same time harshly criticized it for failing to include details requested by Congress, among them the estimates by each of the armed services of the cost of protecting or replacing the ten most vulnerable military bases.

Rising seas: to keep humans safe, let nature shape the coast
Even under the most conservative climate change scenarios, sea levels 30cm higher than at present seem all but certain on much of the U.K.’s coast by the end of this century. Depending on emission scenarios, sea levels one meter higher than at present by 2100 are also plausible. The knee-jerk reaction to sea level rise has traditionally been to maintain the shoreline’s position at all cost, by building new flood defense structures or upgrading old ones, but this traditional approach of “grey” engineered sea defenses locks society into ever increasing costs of replacement and maintenance. The alternatives are “nature-based solutions” to coastal flooding and erosion, which work with natural processes to reduce flood risk and incorporate ecosystems into flood defense.

Under-road heating system to keep Europe’s highways ice-free
Snow and ice can dramatically change the conditions of a road, where slippery surfaces make it harder to keep control of a vehicle, particularly when braking or turning. Under-road heating that melts ice and snow within 15 minutes and real-time information about icy road conditions could help prevent wintertime accidents.

Understudied terrorists put under a microscope
Bombs exploding, hostages taken and masked gunmen firing machine guns are all types of terrorist attacks we’ve seen. According to a new study, it’s the attacks we don’t see – cyberattacks – that happen more often and can cause greater destruction. “Little work has been done around the use of the internet as an attack space,” said Thomas Holt, Michigan State University professor of criminal justice and lead author. “The bottom line is that these attacks are happening and they’re overlooked. If we don’t get a handle understanding them now, we won’t fully understand the scope of the threats today and how to prevent larger mobilization efforts in the future.”
