The Earth Alive and Well?
Jimmy Carter
“It is good to realize that if love and peace can prevail on earth, and if we can teach our children to honor nature's gifts, the joys and beauties of the outdoors will be here forever.”
Chief Seattle’s Thoughts 1854
How can you buy or sell the sky, the warmth of the land? The idea is strange to us.
If we do not own the freshness of the air and the sparkle of the water, how can you buy them?
Every part of this earth is sacred to my people.
Every shining pine needle, every sandy shore, every mist in the dark woods, every clearing and humming insect is holy in the memory and experience of my people.
The sap which courses through the trees carries the memories of the red man.

Earth’s Climatic ZonesEarth’s Climatic Zones
(a) Rays of sunlight penetrate the lower atmosphere andwarm the earth's surface.
(b) The earth's surface absorbs much of the incoming solar radiation and degrades it to longer-wavelength infrared (IR) radiation, which rises into the lower atmosphere. Some of this IR radiation escapes into spaceas heat and some is absorbed by molecules of greenhouse gases and emitted as even longer wave-length IR radiation, which warms the lower atmosphere.
(c) As concentrations of green-house gases rise, their molecules absorb and emit more infrared radiation, which adds more heat to the lower atmosphere.

State will sue over polar bear listing, Palin saysSPECIES STATUS: Unreliable data, threat to energy development cited.By DAN JOLINGThe Associated PressPublished: May 22nd, 2008 01:26 AMLast Modified: May 22nd, 2008 10:10 AMThe State of Alaska will sue to challenge the recent listing of polar bears as a threatened species, Gov. Sarah Palin said Wednesday.
She and other Alaska elected officials fear a listing will cripple oil and gas development in prime polar bear habitat off the state's northern and northwestern coasts.Palin argued there is not enough evidence to support a listing. Polar bears are well-managed and their population has dramatically increased over 30 years as a result of conservation, she said.
