Old Weather group volunteer Michael Purves poses for a photograph looking over the Pacific Ocean from the Dallas Road Waterfront Trail in Victoria, British Columbia, Canada, November 13, 2019. A group of far-flung volunteers called Old Weather is painstakingly extracting data from the handwritten logbooks of 19th-century ships to help us understand how the Earth's climate is changing. Founded a decade ago, Old Weather's volunteers have accumulated an astonishing 4 million observations of weather and ice, taken mostly from the logbooks of ships plying northern or Arctic routes.

Nestled between icy peaks and lapped in frozen ocean waters, the tiny town of Tasiilaq in southeastern Greenland is home to some 2,000 people. Colorful wooden houses dot the sub-Arctic landscape battered by one of the harshest climates on the planet. But global warming is reshaping the world's largest island, causing the ice sheet to melt at a faster rate than previously thought, according to recent research. As scientists study the threats posed by a warming climate, some of the immediate effects of climate change have been a double-edged sword for some in and around Tasiilaq.

A couple of polar bears, Felix (L), a nine-year-old, and Aurora, a six-year-old, walk inside its enclosure at the Royev Ruchey Zoo in Krasnoyarsk, Siberia, Russia, March 29, 2016. Zoo keepers have allowed the bears to live together hoping that they will mate. Both bears were rescued by people in the Arctic Ocean, and were brought to the Krasnoyarsk zoo. A weak orphaned cub, Felix was delivered to the zoo from a scientific polar station on the Wrangel Island in May 2006. Aurora and her sister, Victoria, were found without their mother along a coast of Russia's Taymyr Peninsula in May 2010, according to zoo representatives.
