Here is a bird-shaped iceberg near Petersburg, Alaska.  They often get hung up along the shores as the tide goes out, and they make peculiar noises through the night as they break up from their own weight.  Don't believe any misleading impressions from Michael Crichton's novel, State of Fear, that many glaciers around the world are getting larger. The vast majority, especially those around Alaska and Greenland, are melting at alarming rates.

This oft-photographed view of Bartolome Island, in the Galapagos archipelago, shows a tuff cone at right called Pinnacle Rock.  When I visit these 'enchanted islands' I am grateful to Charles Darwin for his insight.  His Theory of Evolution seems intuitively obvious now, and, given the recent biochemical data that support it, I'm amazed at the controversy that persists.  Man should now focus on understanding the evolution of the Earth's atmosphere, and respond with determined care.

My daughter, Rachel, took this photo of a Hawaiian goose, or Nene, near the summit of Haleakala in Maui.  Derived from the Canada goose, it was common in Captain Cook's day, was reduced to only 30 birds by 1952, and has now increased to about 900 in number.  It is easy to see evolution at work here, and the benefits of man's protection.

This photo was taken shortly after Christmas, 2005, from the road to Hana along the north shore of the island of Maui.  The power behind these rollers that have travelled across thousands of miles of open Pacific Ocean are marvelous to behold.  Fortunately for the people of Hawaii, their islands are young, volcanic and rise fairly abruptly out of the ocean.  Thus, as the global glaciers and polar ice caps melt, Maui will become two islands again, and Hawaiians will only lose some sugar cane, an aquarium, and some hotels between the two volcanos there.  But other islands and lowlands around the world will not fare as well.  Climate change is a serious issue, and should be taken seriously.
