• Disasters Around the World Are Linked by the Same Root Causes

    Climate catastrophes, pandemics, and other crises ultimately stem from the same root causes, says an expert. These have more in common than people realize or plan for.

  • Hurricane Ida Shows the Increasing Impact of Climate Change Since Katrina

    While no two disasters are the same, looking at differences between past and present disasters can help us to better understand what is needed to prepare for future disasters. Given the scope of the emerging impacts of Hurricane Ida, we see that while this is not a repeat of a Katrina disaster, questions are being raised about the effect of climate change and the resiliency of lifeline infrastructure like electricity.

  • Future Flooding in Venice: Facing Sea Level Rise

    A new assessment of flood risk in Venice indicates that the impact of higher emissions on relative sea level rise during this century will be critical in planning future defense infrastructure for Venice and other coastal cities.

  • More Weather-Related Disasters Over Past 50 Years, Causing More Damage but Fewer Deaths

    A disaster related to a weather, climate, or water hazard occurred every day on average over the past 50 years – killing 115 people and causing $ 202 million in losses daily. But while the number of climate change-driven disasters has increased by a factor of five over the 50-year period, the number of deaths decreased almost three-fold. thanks to improved early warnings and disaster management.

  • As Western U.S. Is Experiencing a 1,000 Year Drought, Desalination Could Be a Solution

    The Western United States is currently experiencing what one paleoclimatologist called “potentially the worst drought in 1,200 years.” The region has had many droughts in the past, including “megadroughts” that last decades, but climate change is making dry years drier and wet years wetter. One possible solution is the desalination of seawater, but is it a silver bullet?

  • At Least 23 Killed in Flooding in New York City, New Jersey

    At least 23 people have died across New York City and New Jersey as a result of the historic flash flooding caused by the weather system formerly known as Hurricane Ida. The storm dumped so much rain in New York City that the local National Weather Service issued its first flash flood emergency for NYC and the neighboring city of Newark, New Jersey.

  • Hydropower Faces the Future Challenge of Extreme Weather?

    Hydropower has long been seen as a reliable renewable energy source. But during drought and heavy rain, hydropower plants often come to a standstill. Will climate change spell the end for this clean energy alternative?

  • Improving Flood Projections

    Climate change will lead to more and stronger floods, mainly due to the increase of more intense heavy rainfall. In order to assess how exactly flood risks and the severity of floods will change over time, it is particularly helpful to consider two different types of such extreme precipitation events.

  • 2020 Was Among Three Warmest Years on Record

    A new State of the Climate report confirmed that 2020 was among the three warmest years in records dating to the mid-1800s, even with a cooling La Niña influence in the second half of the year. The major indicators of climate change continued to reflect trends consistent with a warming planet. Several markers such as sea level, ocean heat content, and permafrost once again broke records set just one year prior.

  • What Caused Heavy Rainfall Which Led to Western Europe’s Severe Flooding

    Mid-July flooding resulted in at least 184 fatalities in Germany and 38 in Belgium and considerable damage to infrastructure, including houses, motorways and railway lines and bridges and key income sources. Road closures left some places inaccessible for days, cutting off some villages from evacuation routes and emergency response. What was the cause of these devastating floods?

  • The Impact of Extreme Waves on Offshore Structures

    Strong storms can trigger steep, breaking waves that slam into platforms and wind turbines with tremendous force. Scientists are studying the behavior of offshore structures subjected to these kinds of waves. Their goal is to increase safety at sea.

  • New Ways to Assess Climate Change Impacts on Agriculture

    Scientists agree climate change has a profound impact on U.S. agricultural production, but estimates vary, making it hard to develop mitigation strategies. Two agricultural economists take a closer look at how choice of statistical methodology influences climate study results. They also propose a more accurate and place-specific approach to data analysis.

  • Investments in Nature Needed to Stop the Next Pandemic: Experts

    A group of leading scientific experts from the U.S., Latin America, Africa and South Asia released a report outlining the strong scientific foundations for taking actions to stop the next pandemic by preventing the spillover of pathogens from animals to people. Among other findings, the report notes that protecting forests and changing agricultural practices are essential, cost-effective actions to prevent pandemics.

  • Tracking Water Storage: Improving Water Management During Floods, Droughts

    Researchers have created a balance sheet for water across the United States – tracking total water storage in 14 of the country’s major aquifers over 15 years. With longer-term droughts and intermittent intense flooding expected in the future, particularly in the arid western U.S., there is rising concern about overtaxing water resources in the region, especially for irrigated agriculture.

  • Artificial Intelligence Helps Unlock Extreme Weather Mysteries

    A new machine learning approach helps scientists understand why extreme precipitation days in the Midwest are becoming more frequent. It could also help scientists better predict how these and other extreme weather events will change in the future.
