• Plants Demand More Water as Climate Warms, Leaving Less for People

    As climate changes, plants in North America, much of Eurasia, and parts of central and South America will consume more water than they do now, leading to less water for people, according to a new study. The research suggests a drier future despite anticipated increases in precipitation in populous parts of the United States and Europe that already face water stresses.

  • World Scientists Declare Climate Emergency

    A global coalition of scientists says “untold human suffering” is unavoidable without deep and lasting shifts in human activities that contribute to greenhouse gas emissions and other factors related to climate change. In a paper published in BioScience, the authors, along with more than 11,000 scientist signatories from 153 countries, declare a climate emergency, present graphics showing trends as vital signs against which to measure progress, and provide a set of effective mitigating actions.

  • California Wildfires Signal the Arrival of a Planetary Fire Age

    Another autumn, more fires, more refugees and incinerated homes. For California, flames have become the colors of fall. Stephen Pyne writes that free-burning fire is the proximate provocation for the havoc, since its ember storms are engulfing landscapes. But in the hands of humans, combustion is also the deeper cause. Modern societies are burning lithic landscapes - once-living biomass now fossilized into coal, gas and oil - which is aggravating the burning of living landscapes. “Add up all the effects, direct and indirect – the areas burning, the areas needing to be burned, the off-site impacts with damaged watersheds and airsheds, the unraveling of biotas, the pervasive power of climate change, rising sea levels, a mass extinction, the disruption of human life and habitats – and you have a pyrogeography that looks eerily like an ice age for fire,” he writes. “You have a Pyrocene. The contours of such an epoch are already becoming visible through the smoke. If you doubt it, just ask California.”

  • First Statewide Testing of ShakeAlert in the United States

    Earlier this month, the U.S. Geological Survey and the State of California pressed the “go” button to allow the first-ever statewide public testing of the California Early Earthquake Warning System, which is powered by USGS’s earthquake early warning alerts, called ShakeAlerts. Alerts will be delivered by two independent methods, first over the federal Wireless Emergency Alert (WEA) system and second through the University of California Berkeley’s MyShake smartphone app.

  • Faster Computing Helps in Predicting Earthquake Damage to Infrastructure

    Researchers are using high-performance computing systems to better predict how structures will respond to an earthquake along one of the Bay Area’s most dangerous faults.

  • Techno-Fix Futures Will Only Accelerate Climate Chaos – Don’t Believe the Hype

    By Joanna Boehnert and Simon Mair

    Thanks to the efforts of climate activists, the climate and ecological emergency has never been more prominent. But acknowledging the problem is just a starting point. Now this momentum must be harnessed to dramatically reduce greenhouse gas emissions and reverse habitat destruction.

  • Should New York Build a Storm Surge Barrier?

    By Sarah Fecht

    It’s been seven years since Superstorm Sandy brought the city that never sleeps to a grinding halt. The Superstorm Sandy anniversary also marks seven years since New York started talking about building storm surge barriers to protect itself from future storms. At a recent event hosted by Columbia University, experts discussed a study that is evaluating the feasibility of building storm surge barriers around New York and New Jersey. The panelists also debated whether such a measure is a good idea.

  • The Hidden Politics of Climate Engineering

    At this point, the greatest danger of climate engineering may be how little is known about where countries stand on these potentially planet-altering technologies. Who is moving forward? Who is funding research? And who is being left out of the conversation?

  • House Democrats Set to Introduce First-of-Its-Kind Climate Refugee Bill

    Since 2008, catastrophic weather has displaced an average of 24 million people per year, according to data from the Swiss-based nonprofit Internal Displacement Monitoring Centre. That number could climb to anywhere from 140 million to 300 million to 1 billion by 2050. The World Bank estimated last year that climate change effects in just three regions ― sub-Saharan Africa, South Asia and Latin America ― could force 143 million people to flee by the middle of the century. House Democrats are set to introduce the first major piece of legislation to establish protections for migrants displaced by climate change, ramping up a push for a long-overdue framework for how the United States should respond to a crisis already unfolding on its shores.

  • How Climate Change Will Help China and Russia Wage Hybrid War

    Americans and Europeans may not yet notice the existential threat climate change poses, but they had better pay attention to it. Their adversaries could use climate change as a new front in hybrid warfare. “In several African countries we’re already seeing rural settlements disrupted by development projects funded and executed by China,” Howard Jones, CEO of the Born Free Foundation. Told Defense One’s Elizabeth Braw. “Those projects include altering the flows of entire river systems and putting good land to use for export of food and resources to China. Put this together with climate change and pre-existing poverty and we have a huge problem. And why would China care?” Braw adds: “Indeed, China, Russia, and other hostile states can use climate change as a new tool in blended aggression (often called hybrid warfare) against the West.”

  • Deflecting Massive Asteroids With a Nuclear Impulse

    Researchers have completed the first ever in-depth investigation into how an asteroid would respond to a nuclear deflection attempt. “The whole purpose of studies like this is to help us shorten the response timeline if we were to see something coming at us,” said one researcher. “We don’t want to have to scramble to figure out whether to use an impactor or a nuclear device on a particular asteroid. These studies help us define those thresholds.”

  • Climate change: Steep Warming Curve for Europe

    Climate is changing: Droughts, floods, and extreme weather events influence agriculture, economy, and society. Improved adaptability of industry and society to the future climate, however, requires reliable statements on medium-term climate development, in particular for certain regions. Researchers develop a new system for a more precise prognosis of the climate in the next ten years.

  • Bans on Rebuilding in Disaster-Prone Areas Ignore Homeowners Preferences – Raising Costs Works Better

    As California’s wildfire season intensifies, a growing number of residents in the state want to ban people from building in areas at greatest risk. That’s because taxpayers bear the burden of protecting homes in dangerous areas when fire breaks out – and they often help foot the bill when it’s time to rebuild. A recent assessment showed that 1 in 4 Californians live in an area at “high risk” of wildfire. And people tend to want to rebuild in the same spot that was hit by a disaster. Alexander Smith writes that as a behavioral economist who studies the psychology of decision-making, he tries to understand people’s motivations before taking a position in a policy debate. He believes there’s a better way for policymakers to achieve the same goal of getting people to avoid building in disaster-prone areas without forcing people from their homes.

  • Monitoring Hurricanes: Better Life-Saving, Property-Preserving Decisions

    When a natural disaster strikes, first responders step in to reduce harm and save lives. They risk their lives in highly unpredictable environments — often without clear knowledge of the dangers they are facing or where they are needed most. Now, imagine if responders could make use of cutting-edge disaster forecasting models in conjunction with real-time data to predict a disaster’s impact and then use that information to make better-informed decisions. Fewer lives would be lost and more people would receive the help they need.

  • Robotic Lifeguard EMILY Proves Itself in the Wake of Hurricane Dorian

    The responders who came to the rescue a day after Hurricane Dorian finished lashing Abaco Island in the Bahamas had a tool to get ashore, so they could provide medical care and supplies to stricken islanders. It was EMILY the robotic lifeguard—officially known as the Emergency Integrated Lifesaving Lanyard—a remote-controlled unmanned surface vehicle that has proven its mettle saving imperiled swimmers during natural disasters and humanitarian crises.
