• Modeling Catastrophic Impacts, Risk Assessment of Climate Change

    The insurance and reinsurance sector are at the forefront of translating weather and climate information into financial and societal risks, but the industry’s focus has been on use of catastrophe models rather than incorporating climate change data and projections that can help characterize future conditions.

  • In Years After El Niño, Global Economy Loses Trillions

    In the years it strikes, the band of warm ocean water known as El Niño that spans from South America to Asia triggers far-reaching weather changes resulting in devastating floods, crop-killing droughts, plummeting fish populations, and an uptick in tropical diseases.

  • Long-Term Coastal Cliff Loss Due to Climate Change

    The dangers of coastal erosion are an all-too-familiar reality for the modern residents of California’s iconic mountainous coastal communities. New tool brings historical perspective to the topic of how to manage these disappearing coastlines.

  • Possible Future Health Impacts Related to Climate Mitigation

    Reduce fossil fuel use and air quality will improve, right? It might not be as straightforward as it appears, according to researchers. Some climate change mitigation measures may cause worsening of air quality.

  • Global Temperatures set to Reach New Records in Next Five Years

    Global temperatures are likely to surge to record levels in the next five years, fueled by heat-trapping greenhouse gases and a naturally occurring El Niño event. There is a 66% likelihood that the annual average near-surface global temperature between 2023 and 2027 will be more than 1.5°C above pre-industrial levels for at least one year.  There is a 98% likelihood that at least one of the next five years, and the five-year period as a whole, will be the warmest on record.

  • One in Six Properties in England Will Be Affected by Flood Risk by 2050: Study

    Flood risk affects English residential property values. New report shows that residential properties at risk of flooding are sold at 8.14% lower on average compared to non-affected properties. The report shines a light on the extent to which climate change and the increased propensity of natural disasters is affecting the housing market.

  • Commercial Investors Shift Perspective of Coastal Properties in Face of Climate Change

    Investors in commercial real estate are rethinking the values of coastal properties exposed to flood risk — even in northern U.S. locales that haven’t suffered flood damage, according to researchers. This shift in perspective has implications for investors and developers alike as they determine the value of coastal properties amid a changing climate.

  • Americans’ Support for Nuclear Power Soars to Highest Level in a Decade

    A Gallup survey released in late April found that 55 percent of U.S. adults support the use of nuclear power. That’s up four percentage points from last year and reflects the highest level of public support for nuclear energy use in electricity since 2012. As the country looks to decarbonize, the popularity of nuclear continues to climb.

  • Sustaining U.S. Nuclear Power Plants Could be Key to Decarbonization

    Nuclear power is the single largest source of carbon-free energy in the United States and currently provides nearly 20 percent of the nation’s electrical demand. New research sought to answer the question: Just how much do our existing nuclear reactors contribute to the mission of meeting the country’s climate goals, both now and if their operating licenses were extended?

  • Shutting Down Nuclear Power Could Increase Air Pollution

    Nearly 20 percent of today’s electricity in the United States comes from nuclear power. The U.S. has the largest nuclear fleet in the world, with 92 reactors scattered around the country. Many of these power plants have run for more than half a century and are approaching the end of their expected lifetimes. If reactors are retired, polluting energy sources that fill the gap could cause more than 5,000 premature deaths, researchers estimate.

  • “Statistically Impossible” Heat Extremes Are Here: Study Identifies the Regions Mmost at Risk

    In the summer of 2021, Canada’s all-time temperature record was smashed by almost 5℃. Its new record of 49.6℃ is hotter than anything ever recorded in Spain, Turkey or indeed anywhere in Europe. One of the most important questions when studying these extreme heatwaves is “how long do we have to wait until we experience another similarly intense event?”. This is a challenging question but, fortunately, there is a branch of statistics, called extreme value theory, that provides ways in which we can answer that exact question using past events.

  • Colorado River Water Plan Could Trigger Unprecedented Supply Cuts, Ripple Effects on Key Industries

    Decades of drought and overuse have brought the river’s water levels to historic lows. States in the Lower Colorado River Basin — Arizona, California and Nevada — now must choose between one of three options proposed by the federal government. The economic impact of the river’s dwindling water supplies is could be disastrous.

  • Poorly Understood Environmental Trends Could Become Tomorrow’s Security Threats

    There is an urgent need to understand how a range of emerging ecological challenges could trigger catastrophic instability and insecurity, argues a new report. The authors stress that uncertainty and knowledge gaps should galvanize rather than delay both research and action to prevent, mitigate or adapt to consequences that could be catastrophic.

  • “Flash Droughts” More Frequent as Climate Warms

    ‘Flash droughts’ have become more frequent due to human-caused climate change, and this trend is predicted to accelerate in a warmer future. Flash droughts, which start and develop rapidly, are becoming ‘the new normal’ for droughts, making forecasting and preparing for their impact more difficult.

  • Critical Metal Needs Rise as Cars, Trucks Decarbonize

    The demand for battery-grade lithium, nickel, cobalt, manganese and platinum will climb steeply as nations work to reduce greenhouse gas emissions through mid-century, but will likely set off economic snags and supply-chain hitches.
