• Climate Change Significantly Increases Population Displacement Risk

    The risk of people being forced from their homes by flooding increases by half for each additional degree of global warming, as an international research team led by the Weather and Climate Risks Group at ETH Zurich demonstrate.

  • The Cost of a Key Climate Solution

    Perhaps the best hope for slowing climate change – capturing and storing carbon dioxide emissions underground – has remained elusive due in part to uncertainty about its economic feasibility. Researchers have estimated the energy demands involved with a critical stage of the process.

  • A Sponge to Soak Up Carbon Dioxide in the Air

    Human activity is now leading to the equivalent of 40 billion tons of carbon dioxide emitted into the atmosphere each year, putting us on track to increase the planet’s temperature by 1.5 degrees Celsius over pre-industrial levels by 2040. Increasingly, scientists are recognizing that negative emissions technologies (NETs) to remove and sequester carbon dioxide from the atmosphere will be an essential component in the strategy to mitigate climate change.

  • Responding to Climate Change: U.S. Should Cautiously Pursue Solar Geoengineering

    Given the urgency of the risks posed by climate change, the U.S. should pursue a research program for solar geoengineering — in coordination with other nations, subject to governance, and alongside a robust portfolio of climate mitigation and adaptation policies, says a new report. The report emphasizes that solar geoengineering is not a substitute for reducing greenhouse gas emissions.

  • Tsunamis It Comes in Waves

    Tsunamis pose a real threat to the California coast, even if the triggering earthquakes occur elsewhere. And it doesn’t take a 50-foot tsunami out of a science-fiction film to inflict severe damage. Researchers are helping ensure coastal cities are ready.

  • Sea Levels Are Rising Fastest in Big Cities – Here’s Why

    It is well known that climate-induced sea level rise is a major threat. What is less well know is the threat of sinking land. And in many of the most populated coastal areas, the land is sinking even faster than the sea is rising.

  • Post-wildfire Landslides Becoming More Frequent in Southern California

    Southern California can now expect to see post-wildfire landslides occurring almost every year, with major events expected roughly every ten years, a new study led by U.S. Geological Survey researchers finds.

  • Sustainable Water Management Key to Scaling Up Bioenergy Production

    To avoid a substantial increase in water scarcity, biomass plantations for energy production need sustainable water management, a new study shows.

  • Sea-Level Rise up to Four Times Global Average for Coastal Communities

    Coastal populations are experiencing relative sea-level rise up to four times faster than the global average – according to new research. is the first to analyze global sea-level rise combined with measurements of sinking land.

  • Solar-Powered Lunar Ark as “Modern Global Insurance Policy”

    Researchers are taking scientific inspiration from an unlikely source: the biblical tale of Noah’s Ark. Rather than two of every animal, however, their solar-powered ark on the moon would store cryogenically frozen seed, spore, sperm and egg samples from 6.7 million Earth species. The ambitious project proposed by a University of Arizona team aims to preserve humankind - and animal-kind, plant-kind and fungi-kind - in the event of a global crisis.

  • Major Floods Increased in Temperate Climates but Decreased Elsewhere

    Severe river floods are escalating in temperate climates and putting at risk populations, livelihoods and property, according to new research. The research shows that dangers of extreme river flooding demand close monitoring of rivers for decades to come, to understand and account for the potential impact of such changes.

  • Sustainable Water Management Key to Scaling Up Bioenergy Production

    Bioenergy is frequently considered one of the options to reduce greenhouse gases for achieving the Paris climate goals, especially if combined with capturing the CO2 from biomass power plants and storing it underground. To avoid a substantial increase in water scarcity, biomass plantations for energy production need sustainable water management, a new study shows.

  • Coastal Changes Worsen Nuisance Flooding on Many U.S. Shorelines

    Nuisance flooding has increased on U.S. coasts in recent decades due to sea level rise, and new research co-authored by the University of Central Florida uncovered an additional reason for its added frequency. Researchers show that higher local tide ranges, most likely from human alterations to coastal areas and estuaries, has increased the number of nuisance flooding days in many coastal locations in the U.S.

  • The Texas Blackouts Showed How Climate Extremes Threaten Energy Systems Across the U.S.

    Pundits and politicians have been quick to point fingers over the debacle in Texas that left millions without power or clean water during February’s deep freeze. Many have blamed the state’s deregulated electricity market, arguing that Texas prioritized cheap power over reliability. But climate extremes are wreaking increasing havoc on energy systems across the U.S., regardless of local politics or the particulars of regional grids.

  • Climate Change Has Caused Billions of Dollars in Flood Damages

    Flooding has caused hundreds of billions of dollars in damage in the U.S. over the past three decades. Researchers found that 36 percent of the costs of flooding in the U.S. from 1988 to 2017 were a result of intensifying precipitation, consistent with predictions of global warming.
