The federal government’s new National Climate Assessment paints a grim portrait of climate change’s impacts on the United States. The 841-page report is full of graphics explaining how the rise of greenhouse gas emissions is already transforming the American West and the rest of the country. I’ve extracted the 14 images that I found most […]

When conditions change in the slightest—whether in temperature, base depth, or type of snow—devotees take note. But it can be hard to tell whether conditions on the local slopes in a given season […]
Mountains are especially vulnerable to climate change, so scientists are keeping a close watch on species such as the American pika (Ochotona princeps). This small mammal, which resembles a hamster and is a relative of the rabbit, lives in alpine and subalpine terrain across Western North America. Although relatively widespread and usually found in protected […]
