Mastiff on Mountain, North America, 1967
Photograph by Christopher Knight

Crumbling ice makes for a precarious journey for this mastiff sliding down a slope in North America.

As global warming pushes temperatures higher each year, scientists predict that permanent snow lines of mountains around the world will rise, closing skiing resorts, hurting tourism, swelling major rivers, potentially submerging low-lying areas, and significantly changing landscapes.

Photograph by Tim Laman

In Bangladesh's Sundarban Forest, a beekeeper fans smoke into a hive of giant honeybees to calm the swarming insects before collecting their honey. Found in forested areas of the Indian subcontinent, Indonesia, and central China, Apis dorsata, the giant honeybee, grows to nearly an inch (2.5 centimeters) long and builds hives as large as nine feet (three meters) in diameter.

Longnose Hawkfish, Namena Island, Fiji, 2004
Photograph by Tim Laman

Longnose hawkfish, like this brightly patterned creature resting in a bed of soft coral off Fiji Island's Namena Island, are tropical marine fish known for their needle-like snouts and striking red-and-white scales. The fish's common name originates from its hawklike habit of perching on the high ground of reefs, where it surveys its surroundings for predator or prey.

Aurora Borealis, Acadia National Park, Maine, 2005
Photograph by Michael Medford

Nature's light show—aurora borealis—bathes Maine's Acadia National Park in a pink glow. These dazzling patterns in nature, called aurora australis in the Southern Hemisphere, are created when charged particles outside the Earth's atmosphere collide with atoms in the upper atmosphere, producing a glowing display of curtains, arcs, and bands stretching across the sky.

Just-Hatched Froglets, Papua New Guinea, 2001
Photograph by George Grall

Carrying out his fatherly duty, a male Oreophryne frog in Papua, New Guinea, guards his clutch and two newly hatched froglets that rest atop the egg mass. Like many of the Microhylidae family, these frogs bypass the tadpole stage, developing fully within the egg. Male frogs embrace their clutch each night to keep the eggs moist and protect them from predators such as insects.

Yawning Cheetah, Okavango Delta, Botswana, 1999
Photograph by Chris Johns

The world's fastest land animal takes a moment to relax with a yawn on Botswana's Okavango Delta. The teeth of these fleet-footed predators are too small to use as daggers for large kill, but the cats have strong jaws that lock around the throat of prey until the victim stops breathing.

Lights on Street, Key West, Florida, 1999
Photograph by Jim Richardson

Headlights leave a stream of light in a time-exposed photograph of a busy Key West street. Key West is also known as the Conch Republic, a reference to a mock secession the island staged in protest of an April 23, 1982, roadblock the U.S. Border Patrol set up en route to Key West. When complaints that the roadblock hurt tourism went unanswered, the island's mayor declared the Keys' independence from the U.S.

Blue Mosque, Iran, 1999
Photograph by Alexandra Avakian

A tranquil reflecting pool mirrors a blue-tiled mosque in Iran. An Islamic republic since the country's autocratic monarchy was overthrown in 1978, Iran is ruled by a supreme religious leadership that controls most aspects of Iranian society. But a youthful populace—70 percent of Iranians are under 30—with increasing access to Western media is beginning to push against its boundaries.

Photograph by James P. Blair

A canoe glides past fishing boats at dusk on Bangladesh's flood-swollen Sitlakhya River. Notched into eastern India, this predominantly Muslim nation is a dominated by water, with the Bay of Bengal to the south, mighty rivers throughout, and seasonal monsoon and cyclones that flood up to a third of the country every year.

Leopard Seal With a Penguin, Antarctic Peninsula, 2006
Photograph by Paul Nicklen

Photographer Paul Nicklen watched as this 12-foot-long (3.7-meter-long) female leopard seal toyed with her catch, a live penguin chick. "She dropped it on my camera," he said. "Then she opened her mouth and engulfed the camera—and most of my head. After 45 minutes of more threats, she finally relaxed and ate."
