One of the world's last nomadic reindeer people near Mongolia's border with Russia have captivated people from far and wide.

Horntail wood wasp (family Siricidae), attracted by fire damaged wood, observed a year after the McHugh fire along the Seward Highway.

For decades, the crowds of small, dark sea geese on the tundra of southwestern Alaska's Yukon-Kuskokwim Delta have been thinning, a situation opposite that of geese on the North Slope.

On Sunday, Austin Ahmasuk went along the beach to his camp at the Sinuk River, about 28 miles from Nome, and shortly after hitting West Beach past the port, he found one dead seabird on the shore.

The celebrity glacier on the Kenai Peninsula, though relatively small and getting smaller, looms large in the public consciousness.

Deforestation and climate change appear to be amplifying droughts in the Amazon

Knowledge of animals, insects, agricultural techniques and weather patterns is honed from interaction with nature passed down through generations.

Climate change may be responsible for pushing Alaska’s Gray Whales up into estuaries and rivers like the Kuskokwim.

After hitting 100 degrees Wednesday, Portland’s light-rail trains are operating at slower speeds amid concern that the heat will cause tracks to expand and risk a derailment. In exchange for the slow service, inspectors are not checking riders for tickets.

Horned Puffin sighted near Smith Island in the Eastern Strait of Juan de Fuca, WA.

Scientists report the latest data from the Upper Gulf of Mexico, and the results aren’t good.

Human-polar bear interactions are part of life in Arctic communities, but as melting sea ice forces polar bears onto dry land, they are becoming more common and potentially more dangerous. This is the message of a recent scientific paper. Listen now

In 2015, South Asia experienced a deadly heat wave that killed roughly 3,500 people in Pakistan and India in a matter of months. New research suggests the region could face much worse by the end of the century.

The risk associated with any climate change impact reflects intensity of natural hazard and level of human vulnerability. Previous work has shown that a wet-bulb temperature of 35°C can be considered an upper limit on human survivability. On the basis of an ensemble of high-resolution climate change simulations, we project that extremes of wet-bulb temperature in South Asia are likely to approach and, in a few locations, exceed this critical threshold by the late 21st century under the business-as-usual scenario of future greenhouse gas emissions. The most intense hazard from extreme future heat waves is concentrated around densely populated agricultural regions of the Ganges and Indus river basins. Climate change, without mitigation, presents a serious and unique risk in South Asia, a region inhabited by about one-fifth of the global human population, due to an unprecedented combination of severe natural hazard and acute vulnerability.
