• What the Wildfires Tell Us about the Shortcomings of California’s Electric Grid

    In addition to the vast destruction they have caused, the wildfires that have engulfed California in recent weeks have laid bare serious concerns about the state’s electric grid. UCLA’s expert Eric Fournier explains why the architecture of California’s grid isn’t well suited for such extreme conditions and what it would take to improve it.

  • Humans Cause 97 Percent of Home-Threatening Wildfires

    People are starting almost all the wildfires that threaten U.S. homes, according to an innovative new analysis combining housing and wildfire data. Through activities like debris burning, equipment use and arson, humans were responsible for igniting 97 percent of home-threatening wildfires. Moreover, one million homes sat within the boundaries of wildfires in the last 24 years.

  • Combatting Potential Electromagnetic Pulse (EMP) Attack

    Electromagnetic Pulse (EMP) weapons have the potential to disrupt unprotected critical infrastructure within the United States and could impact millions over large parts of the country. DHS says it continues to prepare against evolving threats against the American homeland, most recently highlighting efforts to combat an EMP attack.

  • What’s Ailing California’s Electric System?

    California made headlines for all the wrong reasons recently with widespread rolling power outages in the middle of a heat wave and a pandemic. These blackouts were not an accident—they were intentionally scheduled by the grid operator, the California Independent System Operator (CAISO), due to a shortage of resources available to keep the lights on.

  • Devastating Hurricanes Could Be Up to Five Times More Likely in the Caribbean

    Global warming is dramatically increasing the risk of extreme hurricanes in the Caribbean, but meeting more ambitious climate change goals could up to halve the likelihood of such disasters in the region, according to new research.

  • Sea Level Rise Matches Worst-Case Scenario

    Ice sheets in Greenland and Antarctica whose melting rates are rapidly increasing have raised the global sea level by 1.8cm since the 1990s, and are matching worst-case climate warming scenarios. “The melting is overtaking the climate models we use to guide us, and we are in danger of being unprepared for the risks posed by sea level rise,” says one expert.

  • U.S. Flood Strategy Shifts to ‘Unavoidable’ Relocation of Entire Neighborhoods

    For years, even as seas rose and flooding worsened nationwide, policymakers stuck to the belief that relocating entire communities away from vulnerable areas was simply too extreme to consider — an attack on Americans’ love of home and private property as well as a costly use of taxpayer dollars. Christopher Flavelle writes that now, however, that is rapidly changing amid acceptance that rebuilding over and over after successive floods makes little sense. Using tax dollars to move whole communities out of flood zones is swiftly becoming policy, marking a new and more disruptive phase of climate change.

  • Water Efficiency Achievable Throughout U.S. without Decrease in Economic Activity

    A recent study showed that targeted efforts to increase water efficiency could save enough water annually to fill Lake Mead. It could happen without significantly compromising economic production, jobs or tax revenue.

  • The World's Biggest Waves: How Climate Change Could Trigger Large Landslides and “Mega-Tsunamis”

    Natural hazards which are triggered, made more frequent, or exacerbated by climate change can’t be prevented, but damage to infrastructure and populations can be minimized. This can be achieved through scientific understanding of the physical processes, site-specific engineering risk analysis and coastal management of hazard-prone regions.

  • U.K. Nuclear Power: The Next Huawei?

    London’s relations with China — hailed as entering a “golden era” only four years ago — have deteriorated badly over the coronavirus crisis and the Hong Kong issue, hitting a nadir when the U.K. finally bowed to U.S. pressure to ditch Huawei’s involvement in its new-generation internet (5G) rollout. China warned the U.K. it would face “consequences if it chooses to be a hostile partner” after London announced its Huawei’s decision. Nuclear power, once a key part of the U.K. energy plans, faces rising costs, cheaper renewables, and domestic opposition – but it also finds itself at the center of a row between London and Beijing that could prove fatal.

  • Using AI in New Way to Strengthen Power Grid Resiliency

    America’s power grid system is not only large but dynamic, which makes it especially challenging to manage. Human operators know how to maintain systems when conditions are static. But when conditions change quickly, due to sudden faults for example, operators lack a clear way of anticipating how the system should best adapt to meet system security and safety requirements. A new artificial neural network model, created by Argonne scientists, handles both static and dynamic features of a power system with a relatively high degree of accuracy.

  • Sea-Level Rise Linked to Higher Water Tables Along California Coast

    In the first comprehensive study of the link between rising sea levels and inland water tables along the California coast, researchers found an increased threat to populated areas already at risk from rising water tables, and the possibility of flooding in unexpected inland areas.

  • Resilience solutions for international power system planners

    When a power system fails, consequences can be catastrophic. At-risk communities may be left without access to lifesaving medical resources, while sanitation, manufacturing, and other critical services may be rendered powerless and unable to function. If a nation or region is geographically isolated or otherwise poorly equipped to respond, recovery time can take even longer.

  • Vulnerability of Solar Inverters

    Cyber-physical systems security researchers can disrupt the functioning of a power grid using about $50 worth of equipment tucked inside a disposable coffee cup. In a presentation delivered at the recent Usenix Security 2020 conference, the researchers revealed that the spoofing mechanism can generate a 32 percent change in output voltage, a 200 percent increase in low-frequency harmonics power and a 250 percent boost in real power from a solar inverter.

  • A Warming California Will See Reservoirs Overwhelmed by Floods

    By the 2070s, global warming will increase extreme rainfall and reduce snowfall in the Sierra Nevada, delivering a double whammy that will likely overwhelm California’s reservoirs and heighten the risk of flooding in much of the state.
