The Tianshan No. 1 glacier is melting fast, receding by at least 30 feet each year. Scientists warn that the glacier — the source of the Urumqi River, which more than 4 million people depend on — may disappear in the next 50 years. Rob Schmitz/NPR hide caption
'Impossible To Save': Scientists Are Watching China's Glaciers Disappear
Many glaciers are melting in Alaska. Scientists believe climate change is at work. Shankar Vedantam/NPR hide caption
Bull trout are running out of time in Montana as their traditional waters heat up, biologists say. By moving more than 100 fish to higher elevations, fisheries scientists hope to save the species by seeding a new population in waters that will stay cooler longer. Jim Mogen/USFWS hide caption
Scientists Try Radical Move To Save Bull Trout From A Warming Climate
Floodwaters from rising sea levels have submerged and killed trees in Bedono village in Demak, Central Java, Indonesia. As oceans warm, they expand and erode the shore. Residents of Java's coastal villages have been hit hard by rising sea levels in recent years. Ulet Ifansasti/Getty Images hide caption

The small patch in the middle of the image is Aulacomnium turgidum, a type of bryophyte plant. Researchers in the Canadian Arctic say they are surprised the bryophytes were still green, even after being covered by ice. Courtesy of Caroline La Farge hide caption
