List of most-at-risk L.A. buildings to be released
Scientists have compiled a list of concrete buildings in Los Angeles which could be at risk of collapsing in a major earthquake. The list identifies about 1,500 concrete structures built before 1980 which need further study to determine their risk level. Structural engineers insist that hundreds could die if any of the buildings collapsed.

Sea-level rise could exceed one meter in this century: experts
Sea-level rise in this century is likely to be 70-120 centimeters by 2100 if greenhouse-gas emissions are not mitigated, a broad assessment of the most active scientists who research in the area, and who are the most prolific publishers on that topic, has revealed. In contrast, for a scenario with strong emissions reductions, experts expect a sea-level rise of 40-60 centimeters by 2100. Ninety international experts, all of whom published at least six peer-reviewed papers on the topic of sea-level during the past five years, provided their probabilistic assessment.

Understanding Greenland Ice Sheet melting helps sea-level forecasts
New insight into how glacier movement is affected by melting ice in summer could help predictions of sea level rise. In 2012, an exceptionally warm summer caused the Greenland Ice Sheet to undergo unprecedented rates of melting. Researchers have found, however, that fast summer ice flow caused by significant melting is cancelled out by slower motion the following winter.

Smaller asteroids could cause bigger problems
On 15 February an asteroid burst over the Russian city of Chelyabinsk. Scientists estimate that the Chelyabinsk event was equivalent to an explosion of about 500 kilotons of TNT. At its peak, the airburst appeared to be thirty times brighter than the sun. The asteroid fireball that injured about 1,500 people and damaged more than 7,000 buildings, collapsing roofs, and breaking thousands of windows. Scientists say that because the frequency of a strike of an asteroid of this size has exceeded expectations, with three such strikes in just over a century – Chelyabinsk in 2013, Tunguska in 2008, and a large airburst in the South Atlantic in 1963 — the number of similar-sized asteroids capable of causing damage may be greater than suspected.

Study finds more spending on fire suppression may lead to bigger fires
Researchers found that fire management can fall into the firefighting trap: Energy and resources are spent mostly on fire suppression — putting out fires in the moment — while less attention is devoted to fire prevention, such as clearing brush and building fire lanes during the off-season. After severe fires, policymakers funnel even more funds into fire suppression for the next season, but this attention to fire suppression may undermine prevention efforts. The result, counterintuitively, is even worse fires the following season, due to the buildup of fire-prone materials such as dried tinder and dead trees. The researchers emphasize balancing fire suppression with prevention measures.

Financial decision making, risk taking in the face of changing climate
Maximizing returns on financial investments depends on accurately understanding and effectively accounting for weather and climate risks, according to a new study by the American Meteorological Society. An AMS report concludes that financial investments face a range of risks due to existing weather patterns and climate variability and climate change. Even small changes in weather can impact operations in critical economic sectors. At the same time, climate variability and change can either exacerbate existing risks or cause new sources of risk to emerge.

Cyberattacks more serious domestic threat to U.S. than terrorism: FBI
The heads of the Federal Bureau of Investigation(FBI), Department of Homeland Security(DHS), and National Counterterrorism Center(NCTC) have declared cyber attacks as the most likely form of terrorism against the United States in the coming years. “That’s where the bad guys will go,” FBI director James Comey said about cyberterrorism. “There are no safe neighborhoods. All of us are neighbors [online].”

U.S. financial industry pushes Congress to pass cybersecurity bill
Three financial-industry trade groups have issued a letter to senior members of the Senate Select Committee on Intelligenceto re-energize a campaign for moving forward with cybersecurity legislation. The trade groups, representing the U.S. largest financial institutions, said their ability to prevent cyberattacks will be hindered unless Congress acts.

Inkblots bolster security of online passwords
Computer scientists have developed a new password system that incorporates inkblots to provide an extra measure of protection when, as so often occurs, lists of passwords get stolen from websites. This new type of password, dubbed a GOTCHA (Generating panOptic Turing Tests to Tell Computers and Humans Apart), could foil growing problem of automated brute force attacks, and would be suitable for protecting high-value accounts, such as bank accounts, medical records, and other sensitive information.

Coordinating responses to cloud, infrastructure vulnerabilities
Cybercrime presents a significant threat to individual privacy, commerce, and national security. In order to tackle this cross-border threat properly, agents involved in managing and monitoring cyber-risk-critical assets need to be able to cooperate and co-ordinate their prevention strategies. Platforms enabling coordinated cross-border responses already work well for handling malicious activity on the traditional Internet. The advent of cloud computing, however, has created a new set of challenges for security professionals in securing the platforms that deliver the cloud.

The Philippines is victim of geography, poor infrastructure, poverty
Owing to its location and geography, the Philippines is one of the most natural disaster-prone countries in the world. On average the country experiences nine major typhoons and 900 earthquakes annually, and it has twenty-five active volcanoes. Poor infrastructure and pervasive poverty exacerbate the impact of disasters, making them even more deadly and destructive. “In a cruel cycle, poverty and underdevelopment make disasters worse, and disasters make poverty and underdevelopment worse,” one observer notes.

Climate scientists say renewables are not enough
Some of the world’s top climatologists have declared their support for nuclear energy as a complementary energy source, alongside wind and solar as energy, which would cut fossil fuel pollution and reduce the growth of global warming. The scientists say that opposing fossil fuels and promoting renewable energy sources offer but a limited solution.
