• Amid Climate Change and Conflict, More Resilient Food Systems a Must: Report

    Increased demand for water will be the No. 1 threat to food security in the next 20 years, followed closely by heat waves, droughts, income inequality and political instability.

  • Why UK Railways Can’t Deal with Heatwaves – and What Might Help

    Like most construction materials, steel, which rails are made from, expands when air temperature increases. When this movement is restrained by the anchorage, which holds the rail and the sleeper (the rectangular supports for the rails) in place, internal stresses build up, and compression buckles or kinks the rail. Trains cannot travel over rail lines with kinks. In the US, kinks caused by the sun caused over 2,100 train derailments in the past 40 years, equivalent to around 50 derailments per year.

  • Climate Change, Land-Use Changes Increase Likelihood of Flood Events

    The German government estimates the total losses resulting from the disastrous floods in July 2021 at 32 billion euros. To improve future preparedness for such extreme events, researchers advise that risk assessments take greater account of the landscape and river courses, how they change, and how sediments are transported. In addition, projections show an increase in the spatial extent and frequency of such extreme events, as well as higher amounts of precipitation.

  • How Not to Solve the Climate Change Problem

    When politicians talk about reaching “net zero” emissions, they’re often counting on trees or technology that can pull carbon dioxide out of the air. What they don’t mention is just how much these proposals or geoengineering would cost to allow the world to continue burning fossil fuels. I’ve been working on climate change for over four decades. Let’s take a minute to come to grips with some of the rhetoric around climate change and clear the air, so to speak.

  • Europe Heat Wave: U.K. Records Hottest-Ever Temperature

    Western Europe continues to bake in extreme heat, with the UK recording a temperature over 40 degrees Celsius for the first time, and wildfires burning through French forests. Relief is expected later in the week.

  • Britain Isn’t Built to Withstand 40°C – Here Is Where Infrastructure Is Most Likely to Fail

    Climate change is intensifying heatwaves in the UK, an affluent country with the capacity and resources to adapt to warmer temperatures. Still, very little has been done over the past ten years to address overheating in buildings and the rising risk to critical infrastructure. The country is unprepared to handle temperatures of more than 38°C consistently for long periods, which is more common in Mediterranean countries.

  • Water Resources to Become Less Predictable with Climate Change

    Many regions of Earth rely on the accumulation of snow during the winter and subsequent melting in the spring and summer for regulating runoff and streamflow. Water resources will fluctuate increasingly and become more and more difficult to predict in snow-dominated regions across the Northern Hemisphere.

  • U.S. Dominated by Remarkable Heat, Dryness

    June kicked off a very warm and dry start to meteorological summer for the U.S. The U.S. struck with 9 separate billion-dollar disasters so far this year. The average June temperature across the contiguous U.S. was 70.7 degrees F — 2.2 degrees above average.

  • Protecting the Coastline

    Barrier islands protect the coastline from storms, storm surge, waves and flooding. They can act as a buffer between the ocean and beachfront property. But as sea level rises, barrier islands retreat, or move closer toward the shore, which diminishes the buffer and protection. Oceanographers develop new model to better predict barrier island retreat.

  • Climate Models May Underestimate Future Floods

    Climate models may be significantly underestimating how extreme precipitation will become in response to a rise in greenhouse gases in the atmosphere, a new study finds. It all comes down to raindrop physics, says one researcher: Even a slight change in the percentage of each falling raindrop to reach the Earth’s surface can mean the difference between a climate of light drizzles and one that creates unprecedented deluges.

  • To Reach the Public, Highlight the Health Implications of Climate Change: Expert

    Among the health effects of climate change: Increases in extreme heat can lead to more heat-related illness and death from heat stroke and dehydration. Poor air quality can cause more lung infections, asthma and allergy attacks, bronchitis, and deaths. Rising temperatures can also increase the geographic range of disease-carrying insects and animals, resulting in faster and wider spread of diseases like Zika virus. Rising temperatures and extreme weather conditions make it easier for food and water to become contaminated by bacteria, viruses, parasites, and other toxins.

  • Water Scarcity Drives EU Countries to Restrict Access to Drinking Water

    Climate change is making itself felt across the continent, as severe droughts and scarce rain have forced water restrictions in southern European countries. In northern Italy, more than 100 cities and towns have imposed water consumption limits on residents.

  • Winners Announced in DHS $195K Challenge to Counter Extreme Temperatures

    DHS announced the winners of the Cooling Solutions Challenge prize competition. The winners were each awarded funding, which totaled $195,000, for their innovative and creative ideas that sought climate-friendly cooling solutions to protect people in extreme heat conditions.

  • Unprecedented Change in Europe’s Fire Regime Driven by Climate Change

    A new study reveals an unprecedented change in the fire regime in Europe which is related to climate change. The study detected summer and spring seasons with unprecedented values of fire risks over the last years, so many areas of southern Europe and the Mediterranean are reaching extreme conditions conducive to fires.

  • June Heat Waves Break Records Across the Globe

    It’s not your imagination: This summer is already hotter than normal, from the Russian Arctic to the muggy Gulf Coast. With July and August — usually the hottest summer months — still to come, the early extreme heat offers a grim picture of summer’s growing danger.
