Darcy Bourassa was just walking around his house on Tuesday when 'I must have stepped right in the perfect spot and went through.' "What I think was happening here is there's a lot of snow built up it's really insulated in the snow and it hasn't been cold this fall or this winter so there's not a lot of ice penetration underneath that snow."

Scientists analyzed 27 extreme weather events from 2016 and found that global warming was a “significant driver” for most of them. We look at five cases.

A NOAA-sponsored report shows that the warming trend transforming the Arctic persisted in 2017, resulting in the second warmest air temperatures, above average ocean temperatures, loss of sea ice, and a range of human, ocean and ecosystem effects.

Big and fluffy snowflakes fell across parts of south Texas on Thursday, including San Antonio and Austin.

Crews are working to clear snow off of the Richardson Highway near Valdez, after excessive snow has not relented, and an avalanche has poured over the isolated highway stretch.

A new study quantifies the rate at which Eklutna Glacier is losing its icy mass. Between 1957 and 2010, the loss of glacier mass averaged 5 percent a year.

Every winter, a massive infrastructure project takes place on the North Slope one thats designed to disappear. Ice roads are built to minimize the oil industrys footprint on the sensitive tundra, and melt away in spring. Many of the oil industrys multi-million dollar projects on the North Slope cant be built until the ice roads are finished each year.
