• National Security Agencies Must Include Climate Risks and Their Analyses

    The Pentagon and other federal agencies were given a July deadline to draw up plans for potential climate risks, under an executive order by President Biden. Antonio Busalacchi and Sherri Goodman write that such plans are an essential first step, but the greater challenge for national security agencies is to continue to redirect their focus to changing climate conditions that pose a complex, two-pronged threat: social and political instability overseas and damage to U.S. infrastructure.

  • Administration Commits $3.46 Billion to Reduce Effects of Climate Change

    Communities across the country have been impacted by the effects of hurricanes, floods, wildfires, earthquakes, and other events. The increasing duration, intensity, and severity of such disasters—which are exacerbated by climate change as well as changes in population, land use, and weather patterns—are alarming and devastating. New funds made available by the government for hazard mitigation.

  • Warming to Affect Water Availability for Hydropower, Public Water Supply in Wales

    New research shows that as the temperature increases, water supplies in Wales dwindle, leading to shortages for both the hydropower industry and public water consumptions. As the temperature rises, more water will have to be released from reservoirs to satisfy consumer demands – but such releases will lower water levels in the reservoirs below the needs of hydropower generation.

  • “Less Than 1% Probability” that Increase in Earth’s Energy Imbalance Occurred Naturally

    The fundamental energy balance sheet for our planet is straightforward: Sunlight in, reflected and emitted energy out. If the Earth’s oceans and land surfaces send as much energy back up to space as the sun shines down on us, then our planet maintains equilibrium. But for decades the system has been out of balance, resulting in the growing number, intensity, lethality, and damage of extreme weather events. The reason: The increasing emission of greenhouse gases.

  • How Summer 2021 Has Changed Our Understanding of Extreme Weather

    A series of record-breaking natural disasters have swept the globe in recent weeks. Many of these events have shocked climate scientists. Some scientists are beginning to worry they might have underestimated how quickly the climate will change. Or have we just misunderstood extreme weather events and how our warming climate will influence them?

  • Climate Tipping Points Are Now Imminent: Scientists

    Around 13,000 researchers have called for urgent action to slow down the climate emergency as extreme weather patterns shock the world. They listed three core measures.

  • Extreme Heat Waves in a Warming World Don’t Just Break Records – They Shatter Them

    Scientists have warned for over 50 years about increases in extreme events arising from subtle changes in average climate, but many people have been shocked by the ferocity of recent weather disasters. We need to understand two things about climate change’s role in extreme weather like this: First, humans have pumped so much carbon dioxide and other planet-warming greenhouse gases into the atmosphere that what’s “normal” has shifted. Second, not every extreme weather event is connected to global warming.

  • Cities Unprepared for Intense, Frequent Heat Waves

    Urban centers across the world are unprepared to face brutal, climate change-driven natural disasters. Many emerging global climate risks, such as heat stress, will be especially damaging in urban areas, because of urban infrastructure both exacerbates and fails to handle extreme heat. With over 50 percent of the world’s population residing in densely populated urban areas, heat-related deaths, economic disruption, and infrastructural damage are becoming a growing concern.

  • High-Tide Flood Risk Is Accelerating, Putting Coastal Economies at Risk

    The frequency of high-tide flooding along the U.S. coasts has doubled since 2000, and it’s expected to increase five to 15 times more in the next 30 years. Already, areas at risk from sea level rise have seen decreases in property values, particularly where cities and homeowners haven’t taken steps to increase flood resilience. Insurance premiums are beginning to increase to reflect actual risk, and bond ratings are increasingly being tied to the resilience efforts of communities.

  • Exploring Hydrogen Storage

    Hydrogen is emerging as a low-carbon fuel option for transportation, electricity generation, manufacturing applications and clean energy technologies that will accelerate the United States’ transition to a low-carbon economy. However, a key challenge is to ensure the safe and effective storage of hydrogen.

  • Climate Change’s Role in Germany’s Deadly Floods

    Massive flooding has caused devastation across parts of central Europe. In Germany, more than 125 have been confirmed dead, with hundreds still missing and thousands driven from their homes. Scientists say that climate change had a role in it.

  • Climate Change to Bring More Intense Storms Across Europe

    Climate change is driving a large increase in intense, slow-moving storms, a new study finds. It is these slow-moving storms that have the potential for very high precipitation accumulations, with devastating impacts, as we saw in Germany and Belgium.

  • 5 Million Deaths a Year Linked to Abnormal Temperatures

    More than five million extra deaths a year can be attributed to abnormal hot and cold temperatures, according to a new study.

  • Tackling Climate Change by Storing up the Sun

    “This is the key, the linchpin that will set a lot of things in the right direction,” says Asegun Henry, an MIT mechanical engineering professor.

  • Mapping How Sea-Level Rise Adaptation Strategies Impact Economies, Floodwaters

    Sea levels are expected to rise by almost seven feet in the Bay Area by 2100. New research shows how traditional approaches to combating sea-level rise can create a domino effect of environmental and economic impacts for nearby communities.
