For decades, climate change has had detrimental impacts on Pacific salmon populations. Spawning streams are overheating and droughts are drying up salmon habitats entirely, impacting many food webs from the Rocky Mountains and Coast Ranges to the Pacific Ocean.

Soils across western Washington and southern British Columbia were saturated for much of the season.

According to a new report from NOAA Fisheries, the U.S. South Atlantic marine ecosystem is showing signs of chronic stress and changing ocean conditions, in addition to pressure from a growing coastal population.

Climate change is prompting more wasting disease, but it also hurting the root system of these grasses.

It’s easy to say “just plant more trees” to mitigate air pollution. But how? Where? And what kind?

Ecologists estimate that 15 to 37% of plant and animal species will go extinct as a direct result of the rapidly changing climate.

More than half of nation was in drought by the end of November

Using data gathered from a specially equipped jet that spent a month flying through and studying wildfire plumes, scientists have a better understanding now of how wildfire smoke impacts air quality.

There is growing public awareness that climate change will impact society not only through changes in mean temperatures and precipitation over the 21st century, but also in the occurrence of more pronounced extreme events, and more generally in natural variability in the Earth system.

Retreating glaciers in the Pacific mountains of western North America could produce around 6,150 kilometers of new Pacific salmon habitat by the year 2100, according to a new study.
