...frigid cold of the world's four largest deserts. Known as the 4 Deserts Race, the event takes in the salt plains of the Atacama in Chile, the riverbeds and hills of the Gobi in China, the undulating dunes of the Sahara in Egypt and the icy flats of Antarctica. Participants can tackle all the deserts or just one if they choose. And while organizers provide water and lay on tents and bathing facilities each night, everyone is expected to carry their own food and other essential gear...
...know that Antarctica is balmier and wetter than the surface of Mars? Yet I don't see people lining up to build condos in Antarctica. So how long? A thousand years. Never. We can visit them. But to land there and say, "What an oasis!"--not anytime soon...
...Continents have become classifications of convention, rather than strict geography.

Since that is not the case, it is clear that “continent” now includes national political borders, language isoglosses, and historical circumstances. For example, although Greenland is physically closer to North America, it is a Danish province, and thus a part of the European continent...
...Antarctica's Lake Bonney is an inaccessible place locked under 15 ft. of ice. But scientists may soon explore it, thanks to a 6.5-ft., 3,000-lb. NASA-funded robot sub just tested in Wisconsin's Lake Mendota. The sub performed so well, it could be diving in Lake Bonney by year's end. It may also serve as a prototype for a mission to the icy oceans on Jupiter's moon Europa...
...those frozen, hostile parts of the world that few of us will ever tread. But he's also a dedicated environmentalist who was early to ring the alarm bell on global warming, the effects of which he saw firsthand in his frequent polar expeditions, both in the Arctic and Antarctica. To help raise awareness of the damage climate change is wreaking on the polar regions, next month Steger will be leading a team of six young adventurers on a 1,400-mile, 60-day-long dogsled expedition across Ellesmere Island, in the far Canadian Arctic. The rest of us will...
