A World Without Ice by Henry Pollack Ph.D., Al Gore

By Henry Pollack Ph.D., Al Gore

A cowinner of the 2007 Nobel Peace Prize bargains a clear-eyed clarification of the planet's imperiled ice.

a lot has been written approximately worldwide warming, however the the most important courting among humans and ice has bought little focus-until now. As one of many world's best specialists on weather swap, Henry Pollack offers an available, finished survey of ice as a strength of nature and the aptitude results as we are facing the potential of a global with out ice.

A global with out Ice strains the influence of mountain glaciers on offers of consuming water and agricultural irrigation, in addition to the present result of melting permafrost and shrinking Arctic sea ice-a state of affairs that has degraded the habitat of diverse animals and sparked a world race for seabed oil and minerals. Catastrophic chances loom, together with emerging sea degrees and next flooding of low-lying areas around the world. A international with out Ice solutions our so much pressing questions on this pending challenge, laying out the mandatory steps for dealing with the unavoidable and heading off the unmanageable.

In deep fog a three-dimensional gray shroud settles in, completely disrupting one’s sense of orientation and distance. The Sun in the Antarctic summer is never far above or far below the horizon—it simply rides around the horizon, offering an ever-changing azimuth of illumination that casts pink hues and slowly changing long shadows that sweep across the landscape. The polar circle cuts through the Antarctic Peninsula about halfway through its lineal extent. South of the circle are long stretches of summer, when the Sun never sets, and north of that line the Sun dips just below the horizon for an hour or two, creating a very long “sunset” of delicate pinks, before returning to view and offering direct illumination once again.

The drinking water and agricultural water for almost one quarter of Earth’s population—a number that exceeds the population of the entire Western Hemisphere—come directly from mountain glaciers. An even greater number of people depend on the seasonal replenishment of water from the melting of winter snow to nourish crops at the outset of the growing season. The dramatic shrinking of Arctic sea ice over the past few decades has already triggered international posturing over oil and minerals that perhaps will be discovered on the ocean floor.

The initial focus of the commission was on space, energy, and high technology, but soon encompassed health, agriculture, science, and the environment as well. Within a year the two countries had signed an agreement that addressed environmental issues in the Arctic. Gore and Chernomyrdin both recognized that each country possessed geophysical data about the Arctic Ocean that no longer offered military advantage, because each country had independently acquired the same data. In a remarkable turnabout from the cold war posture, they decided to release the data to the international science community.
