• Montreal: The infrastructure cost of climate change

    Montreal’s climate is changing and will continue to do so at a rapidly increasing rate and with much more spatial variability in the future. “Climate plays a key role in the design and operation of urban infrastructure and to a large extent determines water and energy demands. As a result, changes in climate conditions will have direct impacts on how we design almost any aspect of the city, from its drainage system to its energy use,” explains one expert.

  • Detecting carriers of dirty bombs

    The threat of terrorism in Europe has been on the rise in recent years, with experts and politicians particularly worried that terrorists might make use of dirty bombs. Researchers have developed a new system that will be able to detect possible carriers of radioactive substances, even in large crowds of people. This solution is one of the defensive measures being developed as part of the REHSTRAIN project, which is focused on security for TGV and ICE high-speed trains in France and Germany.

  • Harvey’s losses “would reach $190 billion or 1 percent of the nation's GDP”: AccuWeather

    AccuWeather’s Dr. Joel N. Myers predicts that “The total losses from this storm would reach $190 billion or 1 percent of the nation’s gross domestic product (GDP), countering the expected growth in the economy for the rest of this year.” The one percent loss that AccuWeather is predicting will be spread out over the next 12 months, but the bulk of it will occur over the next four months. “This is the costliest and worst natural disaster in American history,” Myers said.

  • Biosecurity and synthetic biology: it is time to get serious

    Synthetic biology has only been recently recognized as a mature subject in the context of biological risk assessment — and the core focus has been infectious diseases. In the case of biosecurity, we’re already dependent on biology [with respect to food, health etc.] but we still have an opportunity to develop biosecurity strategies before synthetic biology is ubiquitous. There is still an opportunity to act now and put norms and practices in place because the community is still relatively small. “If scientists are not taking care of biosecurity now, other people will start taking care of it, and they most likely will start preventing researchers from doing good science.”

  • “Shape memory” metals for earthquake-resistant construction

    Researchers have found an economical way to improve the properties of some “shape memory” metals, known for their ability to return to their original shape after being deformed. The method could make way for the mass production of these improved metals for a variety of applications, including earthquake-resistant construction materials.

  • Climate change is part of every story now, including Harvey

    “Climate is not central [to the Houston story], but by the same token it is grossly irresponsible to leave climate out of the story, for the simple reason that climate change is, as the U.S. military puts it, a ‘threat multiplier,’” David Roberts writes. “Everything human beings do, we do in a climate (except hang out on the space station, I suppose). Our climate has been in a rough temperature equilibrium for about 10,000 years, while we developed agriculture and advanced civilization and Netflix. Now our climate is about to rocket out of that equilibrium, in what is, geologically speaking, the blink of an eye. We’re not sure exactly what’s going to happen, but we have a decent idea, and we know it’s going to be weird. With more heat energy in the system, everything’s going to get crazier — more heat waves, more giant rainstorms, more droughts, more floods. That means climate change is part of every story now.”

  • Flood-damaged books, documents may be salvageable with electron beam technology

    Documents, books and similar items soaked and muddied in the potentially sewage-laden flood waters produced by Hurricane Harvey may be salvageable with the use of electronic beam technology. The technology is useful for killing mold, fungus, and bacteria that invade moist environments.

  • “Mother nature always bats last, and she always bats 1,000": Rob Watson

    “[T]here’s an uncomfortable point that, so far, everyone is skating around: We knew this would happen, decades ago. We knew this would happen, and we didn’t care. Now is the time to say it as loudly as possible: Harvey is what climate change looks like. More specifically, Harvey is what climate change looks like in a world that has decided, over and over, that it doesn’t want to take climate change seriously” (Eric Holthaus).

  • Don’t blame climate change for the Hurricane Harvey disaster – blame society

    Yes, climate change can and does influence hurricanes. But climate change does not affect people’s vulnerabilities to the hurricane. Neither the climate nor the hurricane’s characteristics made Houston an industrial center of 2.3m people (2017 estimate), an increase of 40 percent since 1990. They did not force Texans to build along the coast or in floodplains without adequate measures, as occurs around the United States. They did not pave over green spaces leading to reduced rainfall absorption. Because vulnerability is not natural, many disaster researchers avoid the phrase “natural disaster.” A hurricane need not become a hurricane disaster – but society let a disaster happen. Blaming climate change, or even just the weather, for the hurricane disaster distracts from individuals’ and society’s responsibility for where we live, how we live and how we support people who cannot help themselves. This vulnerability, not nature and not climate change, causes hurricane disasters.

  • Analysis: Four things Houston-area leaders must do to prevent future flooding disasters

    An unprecedented amount of rain has fallen on the Houston area in the past few days, causing what is likely the worst flooding event that the nation’s sixth-largest metropolitan area has ever experienced — even worse than 2001’s Tropical Storm Allison. This may seem like a freak occurrence. But it is the third catastrophic flooding event this region of 6.5 million people has experienced in three years. And scientists and other experts say that much of the devastation could have been prevented. Here are four steps local leaders could have done to protect the Houston region from Harvey-related flooding — and what they must do to prevent such disasters in the future: Preserve and restore as much prairie land as possible; restrict development in floodplains and buy flood-prone homes; plan for climate change; educate the public.

  • Using metal-digesting microbes to recycle electronics

    If you have never heard of neodymium and dysprosium, you are probably not alone. But chances are, you and nearly every other working-age adult in the United States has a small amount of these metals in your pocket. This is because these so-called “rare earth elements” are key components for cellular phones, among many other high-tech devices. The problem with rare earth elements, as their name suggests, is that they are not often found in economically exploitable ore deposits. They are also very difficult to recycle from, say, used cellphones.

  • Harvey likely to erode, over-wash, inundate 94 percent of Texas beaches

    New projections from the U.S. Geological Survey indicate Hurricane Harvey is likely to cause significant beach erosion along the Texas coastline, with water overtopping dunes and in some cases inundating areas. USGS Coastal Change Forecast model is predicting that 94 percent of Texas’s 367 miles of coastline will undergo some level of beach erosion from the storm surge and large waves Hurricane Harvey produces.

  • Why Houston isn't ready for Hurricane Harvey

    The brunt of Hurricane Harvey is projected to miss Houston, but the sprawling metropolis is likely to face massive flooding from its third crippling storm in the past three years. It underscores a new reality for the nation’s fourth-largest city: Climate change is making such storms more routine. Meanwhile, unchecked development in the Houston area is wiping out the pasture land that once soaked up floodwaters.

  • Federal funding boosts West Coast’s ShakeAlert system

    The University of Oregon has received $1 million from the U.S. Geological Survey (USGS) to help strengthen the state’s monitoring and disaster-preparation efforts. The funds will be used to install, maintain and operate additional seismic-monitoring sites throughout Oregon, and for engaging pilot users of the ShakeAlert system and the public.

  • 139 countries could be powered by 100 percent wind, water, and solar energy by 2050

    The latest roadmap to a 100 percent renewable energy future from twenty-seven experts is the most specific global vision yet, outlining infrastructure changes that 139 countries can make to be entirely powered by wind, water, and sunlight by 2050 after electrification of all energy sectors. Such a transition could mean less worldwide energy consumption due to the efficiency of clean, renewable electricity; a net increase of over twenty-four million long-term jobs; an annual decrease in 4-7 million air pollution deaths per year; stabilization of energy prices; and annual savings of over $20 trillion in health and climate costs.
