Tiny Iceland is a prime exemplar of the complexities wrought by warming climate. It is 11 percent covered by ice, but it is basically also one very large, very active volcanic system. The island has seen fast-increasing temperatures since the 1970s, and glaciers–a big source of tourism and runoff for hydropower–are visibly receding. This cuts various ways. Iceland gets almost all its electricity and heat from hydropower and geothermal wells. Increased glacial runoff means increased generation potential; on the other hand, in 50 or 100 years, Iceland may be mostly land and very little ice, and the runoff could dry up.

The desert sultanate of Oman is home to some of the weirdest—and possibly most useful—rocks on earth. The stark Hajar mountains, near the border with Saudi Arabia, contain a chunk of earth’s mantle—a zone that makes up most of earth’s mass, but normally lies inaccessible to humans, far below the surface. Here, though, a sliver of mantle has made its way up to where we can see and touch it. The outcrop has drawn scientists looking for clues to the dynamics of the deep earth; the origins of life; and, most recently, ways to fight climate change.
