• California’s Wildfires Are 500 Percent Larger Due to Climate Change

    Californians may feel like they’re enduring an epidemic of fire. The past decade has seen half of the state’s 10 largest wildfires and seven of its 10 most destructive fires, including last year’s Camp Fire, the state’s deadliest wildfire ever. A new study finds that the state’s fire outbreak is real—and that it’s being driven by climate change. Since 1972, California’s annual burned area has increased more than fivefold, a trend clearly attributable to the warming climate. “Each degree of warming causes way more fire than the previous degree of warming did. And that’s a really big deal,” Park Williams, a climate scientist at Columbia University and an author of the paper, said. Among the many ways climate change might be messing with the environment, extra heat is among the simplest and most obvious. “Heat is the most clear result of human-caused climate change,” Williams said.

  • DHS S&T announces $35M Funding for Terrorism Prevention, Counterterrorism Research

    The rapidly evolving, diverse terrorist threat continually exploits technological advances to adapt the nature and expand the reach of its tactics. DHS S&T announces $35 million funding opportunity for Terrorism Prevention and Counterterrorism Research (TPCR). TPCR will support academic-led innovation that supports DHS in staying a step ahead of emerging terrorist tactics.

  • Climate Change Is Driving Many California Wildfires

    Against a backdrop of long-term rises in temperature in recent decades, California has seen ever higher spikes in seasonal wildfires, and, in the last two years, a string of disastrous, record-setting blazes. This has led scientists, politicians and media to ponder: what role might warming climate be playing here?

  • Can the “Masters of the Flood” Help Texas Protect Its Coast from Hurricanes?

    After centuries of fighting back water in a low-lying nation, the Dutch have become the world leaders in flood control. And their expertise is helping Texas design what would become the nation’s most ambitious — and expensive — coastal barrier.

  • Southwest to Endure 50 Days or More a Year When Temperature “Feels Like” Exceeding 105 Degrees

    Increases in potentially lethal heat driven by climate change will affect every state in the contiguous U.S. in the decades ahead. Few places would be unaffected by extreme heat conditions by midcentury and only a few mountainous regions would remain extreme heat refuges by the century’s end. The dangerously soaring heat across the U.S. is posing unprecedented health risks.

  • The Coming AI Metamorphosis

    Humanity is at the edge of a revolution driven by artificial intelligence. This revolution is unstoppable. Attempts to halt it would cede the future to that element of humanity more courageous in facing the implications of its own inventiveness. Instead, we should accept that AI is bound to become increasingly sophisticated and ubiquitous, and ask ourselves: How will its evolution affect human perception, cognition, and interaction? What will be its impact on our culture and, in the end, our history?

  • Do Patents Protect National Security?

    On 12 June, the Wall Street Journal broke the story that Chinese firm Huawei Technologies Co. had asserted more than 200 patents against Verizon Communications Inc., reportedly demanding more than $1 billion in licensing fees. On its face, this would seem to be a private patent dispute. But, in fact, it is an important turn of events for national security: The Verizon-Huawei dispute contradicts a view espoused by many experts, and even the Trump administration, about the relationship between national security and intellectual property rights such as patents.

  • Timber Skyscrapers Can Rewind the Carbon Footprint of the Concrete Industry

    Recent innovations in engineered timber have laid the foundations for the world’s first wooden skyscrapers to appear within a decade, a feat that is not only achievable, but one they hope will beckon in an era of sustainable wooden cities, helping reverse historic emissions from the construction industry.

  • California Plans to Better Use Winter Storms to Refill Its Aquifers

    With new rules coming into effect, California farmers and municipalities using groundwater must either find more water to support the aquifers or take cropland out of use. To ease the pain, engineers are looking to harness an unconventional and unwieldy source of water: the torrential storms that sometimes blast across the Pacific Ocean and soak California.

  • U.S. Costal Communities Face More than $400 Billion in Seawall Costs by 2040

    Coastal communities in the contiguous U.S. face more than $400 billion in costs over the next twenty years, much of it sooner, to defend coastal communities from inevitable sea-level rise, according to a new report. This is approaching the cost of the original interstate highway system and will require the construction of more than 50,000 miles of coastal barriers in 22 states by 2040, half the time it took to create the nation’s iconic roadway network.

  • The California Coast Is Disappearing under the Rising Sea. Our Choices Are Grim

    The California coast grew and prospered during a remarkable moment in history when the sea was at its tamest. But the mighty Pacific, unbeknownst to all, was nearing its final years of a calm but unusual cycle that had lulled dreaming settlers into a false sense of endless summer.

  • Searching for Truth: Q&A with Jennifer Kavanagh

    Senior RAND political scientist Jennifer Kavanagh helps lead RAND’s work on “Truth Decay,” the diminishing role of facts and analysis in American public life. Her research has helped set a national agenda to better understand and combat the problem, to explore its historical precedents, and to mitigate its consequences.

  • “Liquid Forensics” Checks Safety of Drinking Water

    Ping! The popular 1990 film, The Hunt for Red October, helped introduce sonar technology on submarines to pop culture. Now, nearly thirty years later, a team of scientists is using this same sonar technology as inspiration to develop a rapid, inexpensive way to determine whether the drinking water is safe to consume.

  • If Aliens Call, What Should We Do? Scientists Want Your Opinion.

    The answer to this question could affect all of our lives more than nearly any other policy decision out there: How, if it all, should humanity respond if we get a message from an alien civilization? And yet politicians and scientists have never bothered to get our input on it. Sigal Samuel writes in Vox that in the age of fake news, researchers worry conspiracy theories would abound before we could figure out how — or whether — to reply to an alien message.

  • Climate Change Made Europe’s Mega-Heatwave Five Times More Likely

    After a series of unusually hot summers, France and other parts of Europe last week experienced another intense heatwave that broke temperature records across the continent. Quirin Schiermeier writes in Scientific American that for one group of climate scientists, the event presented a rare opportunity: to rapidly analyse whether the cause of the heatwave — which made headlines around the world — could be attributed to global warming. After a seven-day analysis, their results are in: climate change made the temperatures reached in France last week at least five times more likely to occur than in a world without global warming.
