Polar Bear Week
Polar Bear Week
While November might bring us a step closer to the holiday season, polar bears have other plans. They gather along the shores of Hudson Bay in Manitoba, Canada, waiting for sea ice to form so they can head back out to hunt seals. That annual spectacle inspired Polar Bear Week, observed during the first week of November, a celebration of the Arctic"s largest land predator. Polar bears are powerful swimmers, expert hunters, and remarkably adapted to life in one of Earth"s harshest environments. Yet shrinking sea ice means many spend longer on land, making it harder to find food and raising the risk of encounters with people.Desktop Version

Its Halloween!
Forget the fog machine. Frankfurt, Germany, has something far more effective: a Gothic cathedral with a tower that looks ready for a midnight séance.

Colorful bald cypress, Xuancheng, Anhui, China
People paddle through a glowing maze of bald cypress in Xuancheng, Anhui, where autumn transforms flooded woodlands into a tapestry of amber, copper, and deep rust. Known scientifically as "Taxodium distichum," bald cypress is unusual among conifers because it sheds its soft, feathery needles each fall, turning reddish-brown before they drop. In North America, it is famous for thriving in swamps, floodplains, and other wet habitats, often developing knobby root projections called "knees" that rise above the surrounding soil and water.Desktop Version

Black lava beach, El Golfo, Lanzarote, Canary Islands, Spain
On Lanzarote, part of Spain"s Canary Islands, geology got carried away. Dark sand meets the Atlantic beneath cliffs streaked with ocher and rust, the handiwork of volcanic activity spanning millions of years.
