How Climate Change Impacing Infrasturcture: Heatwaves Cause Major Problems for U.S. Infrastructure Study reveals

Breaking News, Climate Actions

New York's Third Avenue Bridge got stuck for hours when its metal expanded in the heat, preventing it from closing. Roads have buckled on hot days in several states, including Washington and Wisconsin. Amtrak warned passengers about heat-related problems, leading to a daylong outage between New York and New Jersey. High temperatures pose a growing risk to power lines and rails, causing delays for the train system. The worsening heat is hitting an already troubled U.S. infrastructure system. The American Society of Civil Engineers gave U.S. infrastructure a grade of C- in its 2021 report. Despite some improvements, such as a reduction in the number of poor-condition bridges from over 12% to 7.5% in a decade, many bridges remain old and hard to maintain. Forty percent of the road system i...

Rapid Glacier Melt Threatens Global Freshwater Supplies and Ecosystems

Breaking News, Climate Actions

Roughly one out of every four people on Earth depends on freshwater supplied by glacial regions, which cover 10 percent of our planet's surface. However, this crucial resource is in crisis. New research highlights the alarming pace at which these frozen ecosystems are changing. A study conducted by an international team of scientists reveals that glaciers in the tropics are melting faster than previously forecasted, retreating to sizes researchers did not expect to see for many years. "This shocked us, frankly," said Andrew Gorin, a paleoclimatologist at the University of California, Berkeley, speaking to New Scientist. "I think this is clear evidence that at least one region in the world has now departed the hospitable climatic conditions that have fostered the development of human civ...

Cooling Urban Heat Islands: New Study Highlights the Role of Surrounding Countryside

Breaking News, Climate Actions

Scientists at the University of Surrey's Global Centre for Clean Air Research (GCARE) and Southeast University (China) have discovered that cooling "urban heat islands" may depend significantly on the surrounding rural areas. The study, which analyzed 20 years of data, reveals that rural regions can effectively reduce city temperatures, especially when the rural ring around a city extends for at least half the city's diameter. Urban heat islands, characterized by significantly higher temperatures in city centers compared to their rural surroundings, are a growing concern as global temperatures rise. Traditional approaches to mitigate these effects have focused on integrating green spaces, wetlands, and waterways within urban areas. However, the scarcity of urban land makes these measure...
