• Risks of Megafloods in California Increase

    California is currently contending with historic drought, but climate change is sharply increasing the risk of a catastrophic megaflood that could submerge large swaths of the state and displace millions of residents. The frequency of catastrophic deluges increases as temperatures rise.

  • World's Biggest Ice Sheet Could Cause Massive Sea Rise Without Action

    A new study shows that the worst effects of global warming on the East Antarctic Ice Sheet (EAIS) could be avoided. That depends upon temperatures not rising by more than 2°C above pre-industrial levels.

  • More Than 107M Americans Will Soon Live inside an Emerging “Extreme Heat Belt” with Temperatures above 125 F

    Fifty U.S. counties, home to 8.1 million residents, are expected to experience temperatures above 125°F in 2023, the highest level of the National Weather Services’ heat index. By 2053, 1,023 U.S. counties are expected to exceed this temperature, an area that is home to 107.6 million Americans and covers a quarter of the U.S. land area.

  • Wealthiest Homeowners Most at Risk of Wildfire Hazard

    The top 10 cent most valuable homes in the western United States are 70% more likely to be in high wildfire hazard areas than median-value properties, measured by county.

  • Support for Carbon Capture and Sequestration Key to Greener, More Reliable Grid

    Existing fossil-fuel capacity can play a significant role in reaching net-zero with both current and modified “Section 45Q” tax incentives for carbon capture and storage (CCS).

  • For Advance Drought Warning, Look to the Plants

    Among the extreme weather impacts resulting from climate change, drought is a growing problem around the globe, leading to frequent wildfires, threats to water resources, and greater food insecurity. Researchers find signals in vegetation can help forecast devastating ‘flash’ droughts.

  • Climate Change Is Making Flooding Worse: 3 Reasons the World Is Seeing More Record-Breaking Deluges and Flash Floods

    Although floods are a natural occurrence, human-caused climate change is making severe flooding events more common. I study how climate change affects hydrology and flooding. In mountainous regions, three effects of climate change in particular are creating higher flood risks: more intense precipitation, shifting snow, and rain patterns and the effects of wildfires on the landscape.

  • Using Historical Weather Data to Optimize Power Grid

    With the record-breaking heat and drought conditions states across the U.S. are currently facing, finding a solution to the growing need for reliable power from the electric grid is at an all-time high. Information about past outlier conditions could provide valuable context to help operators better manage the grid during extreme weather.

  • U.S. Senate Approves Bill Containing Texas’ “Ike Dike” Coastal Protection Project

    The U.S. Senate voted to authorize the U.S. Army Corps of Engineers to begin planning for a massive coastal barrier project in Galveston Bay meant to protect against hurricanes’ storm surge. Funding is not yet secured.

  • Europe’s Energy Choice

    Russia’s war in Ukraine and the disruption of Russian gas exports to Europe has triggered an energy crunch, with price spikes unlike anything seen since 1973. And the situation will get worse before it gets better. Responding to the immediate energy crisis in the right way will help to address the broader climate challenge. Authorities must both buffer the shock of the gas crunch in the short term, and accelerate the transition to clean energy in the long -term.

  • New Flood Maps Clarify the Risk Homeowners Face

    Flooding in urban areas cost Americans more than $106 billion between 1960 and 2016, damaging property, disrupting businesses and claiming lives in the process. Determining which areas are most likely to flood amid ever-changing land use and shifting rainfall and climate patterns can be expensive and complicated. New maps more realistically depict flood zones with less effort, lower costs.

  • U.S. Launches Heat.gov with Tools for Communities Facing Extreme Heat

    The administration launched Heat.gov, a new website to provide the public and decision-makers with clear, timely and science-based information to understand and reduce the health risks of extreme heat. Heat.gov will provide a one-stop hub on heat and health for the nation and is a priority of President Biden’s National Climate Task Force and its Interagency Working Group on Extreme Heat.

  • Extreme Heat Causes Record Wildfires, Acres Burned

    In 2022, 38,046 wildfires have burned 5,571,855 acres. This is the most acres burned-to-date in the past 10 years. Both numbers are well above the 10-year average of 32,286 wildfires and 3,328,244 acres burned. Temperatures will rise to 10- 15oF above normal across the Pacific Northwest and 5-10oF above normal in northern California and portions of the Great Basin.

  • 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.
