Plane-mounted laser imaging has allowed scientists to map the size, shape, and density of trees in the Sierra Nevada mountains in California, revealing how low- and moderate-intensity burns make forests more resilient to larger blazes.

A new map shows the height of Earth’s forests, from stubby saplings to timbers towering more than 50 meters tall, across the entire land surface.

Asia saw its warmest April on record

Deep sand movements stirred up by intense storms may offset some of the impacts of coastal erosion caused by sea level rise.

Despite the rapid melting of ice in many parts of Antarctica during the second half of the 20th century, researchers have found that the floating ice shelves which skirt the eastern Antarctic Peninsula have undergone sustained advance over the past 20 years.

Although vegetation is not the only type of debris caused by a hurricane, it is an important predictor of where roads will be blocked.

Some types of soil act more like concrete than a sponge, allowing water to flow off to flood streams, creeks and rivers.

Losing fur seals from the South Shetland Islands means losing crucial genetic diversity the species may need to adapt to rapid climate change.

Wildfires and development threaten that water supply

A blizzard, multiple rainstorms, and melting winter ice swelled rivers out of their banks and across a flat floodplain in Minnesota, North Dakota, and Manitoba.
