Researchers drawing on 100-year-old sources of salmon data have found that recent returns of wild adult sockeye salmon to the Skeena River—Canada’s second largest salmon watershed— are 75 per cent lower than during historical times

A new video from NASA provides a glimpse of global wildfire trends over the past two decades, showing where fires have intensified due to agricultural practices, including in Africa and Southeast Asia, and climate change.

Depending on your side of the aisle, climate change either elicits doomsday anxiety or unabashed skepticism. 

The recent increase in fires adds to the concern from the international scientific community that the Amazon could turn from a wet and fire-resistant jungle into a savannah-like tinder box that would contribute to the rising levels of atmospheric carbon dioxide.

In addition to their role in plant fertilization and reproduction, pollens and spores have another, hidden talent: With a simple treatment, these cheap, abundant and renewable grains can be converted into tiny sponge-like particles that can grab on to pollutants and remove them from water, scientists report. Even better, these treated particles don’t trigger allergies.

A new species of gigantic tumbleweed once predicted to go extinct is not only here to stay — it’s likely to expand its territory. 

Gathering data on Washington state's west side fires may help determine risks for people who have built homes and communities near wooded areas.

The ocean is vast, and fish swim.

With every unfinished meal since Band Aid, you’ve heard it: “people are starving in Africa, y’know”. 

Logging in Melbourne's largest water catchment has led to a loss of water equivalent to the amount used by 250,000 people each year, new research from The Australian National University (ANU) shows.
