The U.S. Is Spending Billions to Reduce Forest Fire Risks – We Mapped the Hot Spots Where Treatment Offers the Biggest Payoff for People and Climate
In a new study, my colleagues and I mapped out where forest treatments can do the most to simultaneously protect communities – by preventing wildfires from turning into disasters – and also protect the forests and the climate we rely on, by keeping carbon out of the atmosphere and stored in healthy soils and trees.

How ERCOT Is Narrowly Getting Through an Extreme Summer — and How Experts Say It Could Do Better
Record-high power demand and faltering electricity sources have tested the grid in the past month, forcing the Electric Reliability Council of Texas to dig deep into its toolbox to keep power flowing.

North America’s Summer of Wildfire Smoke: 2023 Was Only the Beginning
Canada’s seemingly endless wildfires in 2023 introduced millions of people across North America to the health hazards of wildfire smoke. While Western states have contended with smoky fire seasons for years, the air quality alerts across the U.S. Midwest and Northeast this summer reached levels never seen there before. The pressing question on many people’s minds: “Is this the new normal?” From our perspective as air quality scientists, we think the answer is likely “yes.”

Shutting Off Power to Reduce Wildfire Risk on Windy Days Isn’t a Simple Decision – an Energy Expert Explains the Trade-Offs Electric Utilities Face
Maui County is suing Hawaiian Electric, claiming the utility was negligent for not shutting off power as strong winds hit the island in the hours before the city of Lahaina burned. Electricity is critical infrastructure and a foundational bedrock to many other services, so utilities have to balance the risk of keeping power on with the risks created by shutting power off.

The Vital Role of the Civilian Community in Responding to Natural Disasters
Disaster preparedness is not about prediction. Leaders shouldn’t get caught up in trying to define what precisely we need to prepare for and when. Instead, they need to be ready for compounding national disruptions of any kind, at any time. Given the interconnectedness of our modern world, integrating broad economic, social and environmental preparedness will be better for resilience than mapping out overly detailed contingencies.

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.

Sediment Movement During Hurricane Harvey Could Negatively Impact Future Flooding
Enormous amounts of sediment, or sand and mud, flowed through Houston waterways during Hurricane Harvey in 2017, due in part to modifications made by humans to bayous, rivers and streams over the past century. Harvey was the largest rainfall event in U.S. history, and it moved 27 million cubic meters of sediment, or 16 Astrodomes, through Houston waterways and reservoirs. This could seriously impact future flooding events and be costly to the City of Houston.

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.

Towns Could Save Themselves from Wildfire — If They Knew About This Money
There is a huge pot of federal money available to communities across the country — an unprecedented amount that would allow towns to quickly tackle work that otherwise would take decades. But local leaders in many small towns say they have not heard of the program, and most have not drafted the protection plans needed to apply for grants – in fact, less than 10 percent of communities facing wildfire risk have a protection plan.

Climate-Fueled Wildfires Lead to Rethink on Fire Tactics
Climate change is making wildfires more frequent and more destructive, and long-time firefighting strategies are no longer working. Scientists are calling for a radical rethink of how we fight wildfires.

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.

A First: Hurricane Hilary Triggers Southern California’s First Tropical Storm Warning Ever
Hurricane Hilary headed for Mexico’s Baja peninsula as a powerful Category 4 storm on Aug. 18, 2023, and was forecast to speed into Southern California at or near tropical storm strength as early as Aug. 20. For the first time ever, the National Hurricane Center issued a tropical storm warning for large parts of Southern California.

The Surprising Reasons Floods and Other Disasters Are Deadlier at Night
It’s not just that it’s dark and people are asleep. Urban sprawl, confirmation bias, and other factors can play a role.
Why Flash Flood Warnings Will Continue to Go Unheeded
Experts say local education and community support are key to conveying risk.
