The shipping industry is starting to move away from pollutant-intensive heavy fuel oil. Scientists and private companies are betting on a clean replacement technology: hydrogen fuel cells.

When Hurricane Barry came ashore over the weekend, it did not do as much damage as feared, But it tested a number of systems and hurricane protection entities put in place after previous storms.

Heavy rains from Tropical Storm Barry are expected from Florida to Louisiana as the eye of the disorganized storm moves onto land. Flooding is the big concern.

The water in the Gulf of Mexico is hot and the Mississippi River is high. That could spell disaster for Louisiana.

The rain and flooding from Tropical Storm Barry are the biggest threat to Louisiana, particularly in the low-lying areas close to the coast. Evacuations are in place and people are concerned.

As sea levels rise, coastal flooding that used to happen only during storms is increasingly occurring on sunny days. That has local officials reconsidering everything from zoning to police budgets.

Forecasters are nervous that 5G communications could interfere with collecting weather information. 5G happens to use bandwidths that include the frequency emitted by moisture in the air.

Flood insurance is getting increasingly expensive. So Congress is trying to restructure the federal flood insurance program and figure out how to help people who live in flood-prone areas.

Federal flood insurance has become dramatically more expensive in some places, putting it out of reach for many people who live on floodplains.

When people who own dogs are stressed, their dogs also get stressed, a new study suggests. It's another indication of how emotionally synchronized dogs and their humans can be.

The flood risk maps put out by the federal government are notoriously outdated. Many elected officials have suggested fixing the problem by prioritizing funding for a mapping technology called LiDAR.

This week the central U.S. has flooded and experienced deadly and damaging tornadoes. When it comes to what Americans could see more of due to climate change — the links are present, but complicated.

The Arkansas River is rising well above its previous record, and it's forecast to stay that way for days. That's putting pressure on old levees and making it hard for some residents to evacuate.

NOAA forecasts that two to four major hurricanes will form this year in the Atlantic. But even an average year can cause record-breaking damage, as storms get bigger and wetter.

Flooding in America is getting more frequent and severe. Climate change is driving it.

The term "100-year flood" can be confusing and misleading, scientists, local emergency officials and homeowners all agree. Experts say there's a better way to communicate about flood risk.

PFAS are a family of chemicals accumulating in the soil, rivers, drinking water and the human body. How much exposure to these substances in clothes, firefighting foam and food wrap is too much?

A new catalog of Southern California earthquakes is 10 times larger than its predecessor list. The details of frequent, small quakes help scientists study what triggers large, destructive ones.

Maria was the rainiest storm known to have hit Puerto Rico. Scientists say a storm of such severity is nearly five times more likely to occur today, with warmer air and ocean water, than in the '50s.

After back-to-back hurricanes and wildfires, insurers are looking for more-resilient construction materials. That means building model homes and then blowing off their roofs or setting them on fire.
