...Mars too could be home to similarly hearty subsurface life forms, as could two of Jupiter's other moons, Ganymede and Callisto. If the discovery here on Earth of tough little organisms living miles below ground, frozen in polar ice and hanging on in the broiling waters of deep-sea vents indicates anything, it's that biology emerges in very improbable places. The most remarkable thing we may come to conclude about 581c is that whatever secrets it holds may not be that remarkable...
...eventual life change. In the background, an orchestra grates out dissonant tones that gradually climax and make way for Oberst’s lyrics. He delivers a tired outline of the modern condition: “Future Markets, Holy Wars…the freedom-fighting simulcast…the polar icecaps centrifuge…First snowman built at the end of June…fifteen-minute fame.” Oberst eventually asks, “Would you agree times have changed?” The next song, “Four Winds,” busts through with...
...main reason has to do with the Arctic and Antarctic. As polar climates warm enough for trees to move in, the color of that part of the earth will change, as viewed from above. Green trees, which absorb more light, will replace whiter snow and ice, which reflect more rays back to space. Like a dark-colored car hood on a hot day, a dark-colored earth will warm. The group’s computer modeling experiments show that the localized warming due to the change in the earth’s surface reflectivity (called its “albedo?...
...situation is a little different in the tropical regions. Tropical soils are much darker than polar snows, so replacing open land with trees makes little difference as to how much light the land reflects. In fact, planting trees in the tropics actually cools the earth. Warm-weather trees help to draw water out of the ground and into the atmosphere, creating clouds that reflect light and keep the atmosphere cool...
Although military training and beauty pageants may seem to be polar opposites, Sinnott said that pageants and the military have a lot in common...
