A Quote by Jill Tarter
Life has evolved to thrive in environments that are extreme only by our limited human standards: in the boiling battery acid of Yellowstone hot springs, in the cracks of permanent ice sheets, in the cooling waters of nuclear reactors, miles beneath the Earth's crust, in pure salt crystals, and inside the rocks of the dry valleys of Antarctica.

Typically we don't think of cities as being particularly extreme environments, but few places on earth get as hot as a rooftop or as dry as the corner of a heated living room.
All human life has its seasons and cycles, and no one's personal chaos can be permanent. Winter, after all, gives way to spring and summer, though sometimes when branches stay dark and the earth cracks with ice, one thinks they will never come, that spring, and that summer, but they do, and always.
There is good evidence that Venus once had liquid water and a much thinner atmosphere, similar to Earth billions of years ago. But today the surface of Venus is dry as a bone, hot enough to melt lead, there are clouds of sulfuric acid that reach a hundred miles high and the air is so thick it's like being 900 meters deep in the ocean.
The geysers and hot springs of the Yellowstone are another proof of recent volcanic activity.
Consciousness is the mere surface of our minds, of which, as of the earth, we do not know the inside, but only the crust.
I do like a little romance... just a sniff, as I call it, of the rocks and valleys. Of course, bread-and-cheese is the real thing. The rocks and valleys are no good at all, if you haven't got that.
As a scientist, my attention became totally focused on global warming some 15 years ago by the elegant and powerful measurements of carbon dioxide trapped in ice cores taken as much as 2 miles deep from the great East Antarctica ice sheet.
If [science] tends to thicken the crust of ice on which, as it were, we are skating, it is all right. If it tries to find, or professes to have found, the solid ground at the bottom of the water it is all wrong. Our business is with the thickening of this crust by extending our knowledge downward from above, as ice gets thicker while the frost lasts; we should not try to freeze upwards from the bottom.
It's very clear that global climate change is occurring on earth, but it's also been very clear that that has always happened on earth. We've always had a changing climate on earth. We all know about ice ages. We know when our continent was covered with ice sheets. We know glaciers come and they go. It puzzles me that people forget that.
Water covers about 70 percent of the Earth's surface. Of this total, only about 2.5 percent is fresh water, and most of this is frozen in the ice caps of Antarctica and Greenland, in soil moisture, or in deep aquifers not readily accessible for human use.
When Charles Darwin wrote The Origin Of The Species, no one could have known that the ice cap would melt, that the waters would rise and that life on earth would have to evolve in order to live beneath the sea once more or perish. We came from water and now, with the help of stem cell technology and cloning, we must go back to it to survive.When the waters rise, humanity will go back to the place from whence it came.Make no mistake, this is not sci-fi, this is evolution
Ice cores, which are long cylinders scientists extract from glaciers, ice sheets or ice caps, contain gas bubbles, pollen, dust particles, or chemical isotopes that give scientists clues about what Earth's temperature and atmosphere were like when the ice caps first formed.
More than 30 of America's 100 nuclear power reactors have the same brand of General Electric reactors or containment system used in Fukushima.
Viewed from the distance of the moon, the astonishing thing about the earth, catching the breath, is that it is alive. The photographs show the dry, pounded surface of the moon in the foreground, dry as an old bone. Aloft, floating free beneath the moist, gleaming, membrane of bright blue sky, is the rising earth, the only exuberant thing in this part of the cosmos.
It is the hope of those who work toward the breakout from planet Earth that the establishment of permanent, self-sustaining colonies of humans off-Earth will ... make human life forever unkillable, removing it from the endangered species list, where it now stands on a fragile Earth overarmed with nuclear weapons. Second, the opening of virtually unlimited new land areas in space will reduce territorial pressures and therefore diminish warfare on Earth itself.
There is something in such laws that takes the breath away. They are not discoveries or inventions of the human mind, but exist independently of us. In a moment of clarity, one can at most discover that they are there and take them into account. Long before there were people on the earth, crystals were already growing in the earth's crust. On one day or another, a human being first came across such a sparkling morsel of regularity lying on the ground or hit one with his stone tool and it broke off and fell at his feet, and he picked it up and regarded it in his open hand, and he was amazed.
