• How Will We Protect American Infrastructure from Cyberattacks

    As the Colonial Pipeline hack and subsequent shutdown reminded us so recently, our infrastructure’s digital connectedness — while bringing benefits like convenience, better monitoring and remote problem-solving — leaves it vulnerable to cyberattacks.

  • How America Turned the Tables on Huawei

    By Natalie Liu

    The United States started warning allies and partners in 2019 that having the Chinese telecom firm Huawei build their 5G telecom infrastructure risked exposing their citizens’ and their official data to Chinese state surveillance. The Trump administration argued that countries should keep Huawei out, both for their own sake and for the sake of collective security among democratic allies.

  • New Building Standard Can Map Out Tornado Threat for the First Time

    Of the natural hazards in Mother Nature’s arsenal, tornadoes are some of the most vicious. But while other hazards are regularly considered in building designs, tornadoes have not been part of the equation for most structures in the United States, even in highly tornado-prone regions. Now, an upcoming edition of a critical building standard gives tornadoes some much needed attention.

  • Overseas Climate Change Could Devastate U.K.

    The effects of climate change overseas could have a potentially devastating impact on the economy here in the UK. The UK economy is particularly exposed to risks because of London’s prominent role at the center of the global insurance market. Climate change will lead to rising sea levels and wildfires, as well as an increase in the frequency of extreme weather events such as droughts, floods, and severe storms.

  • Acceleration of Coastal Overtopping around the World

    The combination of sea level rise, tides, storm surge and waves has increased the overtopping of natural and artificial coastal protection by nearly 50 percent in the last two decades. By combining satellite data and digital models, the researchers have shown that coastal overtopping, and consequently the risk of flooding, is set to further accelerate over the 21st century, by up to 50-fold under a high emission global warming scenario, especially in the tropics. This increase is principally caused by a combination of sea level rise and ocean waves.

  • Coastal Cities of the Future

    By Karen B. Roberts

    It’s time to put all the options on the table when it comes to discussing climate change adaptation. Managed retreat — the purposeful movement of people, buildings and other assets from areas vulnerable to hazards — has often been considered a last resort. But experts say it can be a powerful tool for expanding the range of possible solutions to cope with rising sea levels, flooding and other climate change effects when used proactively or in combination with other measures.

  • Managed Retreat Conference

    The Columbia Climate School and its Earth Institute, will hold a virtual conference 22-25 June 20201 on the subject of managed retreat. conference will address a range of scientific, social, policy, and governance issues around managed retreat (also known as strategic realignment and planned relocation).

  • Rare Earth Metals at the Heart of China’s Rivalry with U.S., Europe

    What if China were to cut off the United States and Europe from access to Rare Earth Elements (REEs), 17 minerals with unique characteristics which are essential to electric vehicles, wind turbines, drones, batteries, sophisticated military gear, and much more? This is a time of growing geopolitical friction among these three, and the United States and Europe want to change the current dependence on China, where, today, these minerals are largely extracted and refined.

  • The Geopolitics of Rare Earth Elements

    The Covid-19 pandemic has exposed fragility in the global supply chains for not only pharmaceuticals and crucial medical supplies but also some critical minerals. Chief among them are rare Earth elements (REEs), which are necessary for clean energy equipment, advanced military gear, and consumer goods. About 80 percent of the world’s REEs are produced and refined in China.

  • Cyber Regulation Could Be Coming Following Spate of Hacks, Ransomware Attacks

    By Jeff Seldin

    The United States may soon look to regulate private companies, mandating higher standards for cybersecurity following a series of damaging hacks and ransomware attacks against key firms and critical infrastructure. Cybersecurity experts say that malign actors are currently operating with impunity and that too many private sector organizations have, so far, failed to take the necessary precautions. “Enlightened self-interest, that’s apparently not working,” Chris Inglis, tapped to be the country’s first national cyber director, told members of the Senate Homeland Security and Governmental Affairs Committee. “Market forces, that’s apparently not working.”

  • U.S. Attorney General Warns Ransomware “Getting Worse and Worse”

    By Masood Farivar

    U.S. Attorney General Merrick Garland warned Wednesday that ransom-motivated cyberattacks are “getting worse and worse,” echoing other top Biden administration officials who have sounded the alarm about the problem in recent weeks.  “We have to do everything we possibly can here,” Garland told lawmakers. “This is a very, very serious threat.” 

  • Fastly’s Global Internet Meltdown Could Be a Sign of Things to Come

    By David S. Wall

    For an hour on the morning of June, dozens of the world’s most-visited websites went offline. Together, these websites handle hundreds of millions of users. This case illustrates the fragility of an internet that’s being routed through fewer and fewer channels. When one of those major channels fails, in what is called a “single point of failure”, the results are dramatic, disruptive and incredibly costly. It’s urgent we address this significant vulnerability if we’re to avoid another global internet meltdown – but this time caused by criminals, not code.

  • Broad Swath of the Web Knocked Offline by Outage

    A broad swath of the World Wide Web has been knocked offline by an outage at edge cloud CDN specialist Fastly. The company runs an “edge cloud,” which is designed to speed up loading times for websites, protect them from denial-of-service attacks, and help them deal with bursts of traffic. The technology requires Fastly to sit between most of its clients and their users. That means that if the service suffers a catastrophic failure, it can prevent those companies from operating on the net at all.

  • Fastly Global Internet Outage: Why Did So Many Sites Go Down — and What Is a CDN, Anyway?

    By Paul Haskell-Dowland

    If you were having difficulty accessing your favorite website on Tuesday time, you’re not alone. A jaw-dropping number of major websites around the globe suddenly became unavailable with no immediately obvious explanation — before reappearing an hour later. To understand why it happened, you need to know what a CDN (content delivery network) is and how crucial they are to the smooth running of the internet.

  • Envisioning Safer Cities with Artificial Intelligence

    Over the past several decades, artificial intelligence has advanced tremendously, and today it promises new opportunities for more accurate healthcare, enhanced national security and more effective education, researchers say. But what about civil engineering and city planning? How do increased computing power and machine learning help create safer, more sustainable and resilient infrastructure?
