Updated and more accurate federal maps put a cluster of homes near Capisic Brook in a zone that faces once-in-a-century risks.

In one of the planet’s coldest places, 130 kilometers south of Russia’s Arctic coast, scientist Sergey Zimov can find no sign of permafrost as global warming permeates Siberia’s soil. As everything from mammoth bones to ancient vegetation frozen inside it for millennia thaws and decomposes, it now threatens to release vast amounts

The Canadian Armed Forces has begun setting up two water purification units at the Sylvia Grinnell River on Monday morning to help Nunavut’s capital with its ongoing water emergency. The military had been waiting for the City of Iqaluit’s approval before setting up the units. The two parties agreed on the location Sunday night, said

Rising Arctic temperatures are causing permafrost to thaw, putting the world’s largest city built on frozen ground in deep trouble.

Video | In northern Siberia, the warming climate is leaving people feeling like the ground is "going out from under their feet."

Protecting the coast of Tuktoyaktuk from the onslaught of climate change is estimated to cost at least $42 million and is only guaranteed to last until 2052. Over the project’s 30-year lifespan, over 60,000 cubic metres of sand are expected to be brought to keep the beach intact.

Approximately 31 Alaska Native communities face imminent climate change due to floods and erosion. This can lead to the disappearance of culture and lifestyle changes. The four tribes are in the process of relocating from a rapidly disappearing village.

Within a set of glaciers and mountains near Juneau, there’s seismic activity almost every day in the summer. They’re called ice quakes. They’re not as widely understood as earthquakes, but researchers are monitoring them closely.

The U.S. Forest Service said it plans to approve Coeur Alaska’s plan to expand facilities at the Kensington Gold Mine, extending the life of the mine by another 10 years.

A contractor tore down six structures in the past few weeks, part of a process to remove erosion-threatened places that began almost a decade ago.

A researcher's quest to understand a mysterious mass extinction leads to cud-chewing culprits.

Global climate warming is most severe in the Arctic. One consequence is a widespread reduction in permafrost. Continuous, stable permafrost can act as a physical glue that helps anchor unstable slopes. Increasingly, scientists are reporting collapse of rock slopes in the High Arctic.

“We’re dropping in elevation because we live on ice cubes,” says a scientist trying to map permafrost.

Micah Hahn, an assistant professor of environmental health at the University of Alaska Anchorage, says while it might seem obvious that wildfire smoke causes health impacts, there had actually never been a nuanced, scientific look at those impacts. The biggest impact was for asthma-related emergency department visits. This was really across the board and across age groups and in geographic areas.

Fearing that runoff from the December rains might have carried contamination to Henderson Farm in Haines, the American Bald Eagle Foundation has told its renters they won't be able to farm their plots this year.

Upgrades are needed on the tarmac

Climate warming has accelerated the permafrost degradation, which influences the processes of water supply, runoff and discharge in the Source Area of the Yellow River (SAYR) in the northeast of Qinghai-Tibet Plateau.

A federal regulator has lifted a stop-work order on tree cutting and grass mowing along the route of the Trans Mountain pipeline expansion project.

For 30 years now, climate change has been driving the sands further into the Nogai steppe, gradually transforming the traditional homeland of a the people that once dominated much of southern Russia from green and pleasant pasture to barren desert.

Work will stop until 21 August after the discovery of an Anna’s hummingbird nest during construction of TransMountain pipeline
