• A Tropical Storm in California? Warmer Waters and El Niño Made It Possible.

    Tropical Storm Hilary made landfall in Mexico and crossed into California last weekend, knocking out power and drenching wide swaths of southern California. Los Angeles received 2.48 inches of rain on Sunday, breaking a single-day record from 1906 of 0.03 inches. Storm Hilary adds to the lengthy list of climate-fueled disasters this summer.

  • Scientists Are Helping Cities Adapt to Extreme Heat

    Extreme heat is dangerous and is one of the leading causes of weather-related deaths, and in a warming world, extreme heat is becoming the norm, not the exception. Scientists are working to mitigate the effects of extreme heat by developing strategies to build heat resilience which would allow communities to adapt to and thrive in a warming climate.

  • Wildfires Are Much Worse Than a Sign of Climate Change

    Summer headlines have screamed of climate extremes: Record temperatures, an ocean heat wave, and rampant wildfires. The fires present a dual problem: Not only are they a symptom of climate change — becoming bigger, hotter, and more common in regions where they can affect large population centers — but they also make the crisis worse. By burning vast layers of partially decomposed vegetable matter called peat, fires like those in Canada release even more greenhouse gases into the atmosphere.

  • Climate Change and U.S. Property Insurance: A Stormy Mix

    Accelerating risks and damage from climate change are spurring private insurers in the United States to limit coverage in a growing number of areas, thus imposing mounting stress on local communities and straining the country’s overall economic health.

  • Feds Ease Up on Colorado River Restrictions — for Now

    The water shortage crisis on the Colorado River is improving, but it’s far from over. The water levels in the river’s two main reservoirs have begun to stabilize, lessening the need for states in the Southwest to cut their water usage. This year’s wet winter helped save the river from collapse, but a reckoning is on the horizon.

  • Geoengineering Sounds Like a Quick Climate Fix, but Without More Research and Guardrails, It’s a Costly Gamble − with Potentially Harmful Results

    The underlying problem has been known for decades: Fossil-fuel vehicles and power plants, deforestation and unsustainable agricultural practices have been putting more carbon dioxide into the atmosphere than the Earth’s systems can naturally remove, and that’s heating up the planet. Geoengineering, theoretically, aims to restore that balance, either by removing excess carbon dioxide from the atmosphere or reflecting solar energy away from Earth. But changing Earth’s complex and interconnected climate system may have unintended consequences.

  • NREL Analysis Reveals Benefits of Hydropower for Grid-Scale Energy Storage

    Closed-loop pumped storage hydropower systems rank as having the lowest potential to add to the problem of global warming for energy storage when accounting for the full impacts of materials and construction, according to new analysis. These systems rely on water flowing between two reservoirs to generate and store power.

  • More U.S. Crops to Require Irrigation

    With climate change, irrigating more crops in the United States will be critical to sustaining future yields, as drought conditions are likely to increase due to warmer temperatures and shifting precipitation patterns. Yet less than 20% of the nation’s croplands are equipped for irrigation.

  • Heat, Drought, Population Growth Stress Aquifers Which Supply Water to Millions of Texans

    Diminishing springs and aquifers due to heat, drought and high for demand water highlight the urgency for Central Texas conservation districts to prioritize climate-focused management, potentially involving reduced pumping for sustainability.

  • Multi-Billion-Dollar Risk to Economic Activity from Climate Extremes Affecting Ports

    More than $122 billion of economic activity - $81 billion in international trade - is at risk from the impact of extreme climate events, according to new research. Systemic impacts – those risks faced due to knock-on effects within global shipping, trade and supply chains network - will hit ports and economies around the world, even if the local ports are not directly affected by extreme events.

  • Record-Warm Sea Surface Temperatures to Cause “Above Normal” Atlantic Hurricane Season

    Scientists at NOAA’s Climate Prediction Center have increased their prediction for the ongoing 2023 Atlantic hurricane season from a near-normal level of activity to an above-normal level of activity. The reason: current ocean and atmospheric conditions, such as record-warm Atlantic sea surface temperatures, are likely to counterbalance the usually limiting atmospheric conditions associated with the ongoing El Nino event.

  • FEMA Maps Said They Weren’t in a Flood Zone. Then Came the Rain.

    The most common reference for flood risk are the flood insurance rate maps, also known as 100-year floodplain maps, that the Federal Emergency Management Agency, or FEMA, produces. They designate so-called special flood hazard areas that have a roughly 1 percent chance of inundation in any given year. Properties within those zones are subject to more stringent building codes and regulations that, among other things, require anyone with a government-backed mortgage to carry flood insurance. Flaws in federal flood maps leave millions unprepared. Some are trying to fix that.

  • Moving Communities Away from Flooding Risks with Minimal Harm

    As sea levels rise and flooding becomes more frequent, many countries are considering a controversial strategy: relocation of communities. A Stanford analysis of planned relocations around the world reveals a blueprint for positive outcomes.

  • First Three Weeks of July 2023 Warmest on Record, Breaking Global Temperature Records

    Following the hottest June on record and a series of extreme weather events, including heatwaves in Europe, North America and Asia, and wildfires in Canada and Greece, show that the first three weeks of July have already broken several significant records. The first three weeks of the month was the warmest three-week period on record.

  • Paying the Costs of Climate Resilience

    The idea that climate pollution can be eliminated by political edict overestimates political power and underestimates economic power. It is not simply powerful economic interests that influence public policy, but the sense of economic well-being perceived and experienced by the mass public. The maintenance of that sense of well-being is a critical foundation of political stability. The transition to a renewable resource-based economy must be careful to reinforce and not undermine that sense of well-being.
