So far, about a million acres of trees have died from Alaska to California. An Endangered Species Act listing would have made it difficult to log the tree.

Ash, elm and rowan among trees threatened by pests and pollution, says biodiversity report

Biologists say early retreating sea ice is potentially causing vegetation productivity changes on the tundra across Alaska and the Arctic. Uma Bot, a climate variability expert with the University of Alaska–Fairbanks, says the land warms up more quickly when sea ice recedes earlier than usual. “‘Cause the tundra is temperature limited and if it has more …

The top of the world saw record-beating average temperatures flashing through all three summer months.

Climate change is making life difficult for the indigenous people - and wildlife - of the Sami region.

At some point even commercial tree removers will need help with disposal. And what should be planted in their place?

Average temperature for month amid Arctic heatwave was 58.1F (14.5C), nearly 1F above previous high set in July 2004

These tiny, black, thread-like pests dig into plants and like to hang about in gangs, which is why you see so many of them. It is as if they want to be as annoying as possible.

Bees, butterflies, and other insects are under attack by the very plants they feed on as U.S. agriculture continues to use chemicals known to kill.

This ubiquitous shrub of the Pacific Northwest is dying. Some scientists theorize that a disease or fungus could be the culprit, while others point to this past winter’s unusually dry weather.

Earth’s natural cycles can’t account for the recent warming seen over the past 100 years, new research suggests.

The inability of long-rooted trees to reach their subsurface water supply in the Sierra Nevada mountain range led to widespread forest die-offs following the drought of 2012-2015. A new study provides a better understanding of the climatic and biological mechanisms in play.

Mexico has spent US$17 million to remove over a half-million tons of sargassum seaweed from its Caribbean beaches, and the problem doesn't seem likely to end any time soon.

The ‘persistent and widespread decline’ of the province’s official tree is due to drier, California-like summer droughts of two to three months.

The spruce beetles found in Alaska belong to a genus of 17 bark beetle species that are so notorious for destroying trees that it’s named “dendroctonus,” or “tree killer.” Despite

The drought has had damaging economic and ecological impacts.

Sargassum is infesting Mexico’s coastline. Researchers are scrambling to stop an ecological crisis, and maybe even make something good of it.

The die off of Western Red Cedar trees on East Vancouver Island due to drought and severe weather has First Nations extremely worried. Cedar is a critical part of first nations culture and as Skye Ryan reports, there is growing concern the dying trees will have a ripple down effect.

Some Western red cedars are struggling after repeated bouts of drought conditions and experts say expect the tree to vanish for good in spots with shallow, dry, rocky soil.

Researchers have determined that, when ground ice is thicker, reindeer make for the coast. They don't eat kelp when they don't have to.
