Students can look at a globe or map and readily see that water dominates our planet. However, do students know that over 70 percent of the earth’s surface is covered by water? Do they realize the importance of the oceans?
Currently, 80 percent of all people live within 60 miles of a seacoast. Yet many adolescents still do not think […]

When we talk about the problems of global climate change, we tend to focus on cars and coal-burning power plants as major contributors. Yet there are other significant players, including consumer electronics. The number of cell phones, MP3 players, […]

A massive ice bridge, 40 km long and more than 500 m wide, that once connected two islands is no longer. See http://earthobservatory.nasa.gov/IOTD/view.php?id=36060 for a great visual: a labeled photograph of the area. The ice bridge had been in place for hundreds, probably thousands, of years and held back the Wilkins Ice Shelf. Now scientists […]

Success stories in animal preservation are not very common. Since 1973 when the Endangered Species Act was passed, only 16 species of over 1,350 have been delisted. The whooping crane is not one of them, although its numbers have increased from 21 in 1941 to over 350 today. On February 22, 2009, the NYTimes.com published […]

If you saw a newspaper or the news on TV at all last week, you must have heard about the catastrophic bushfires in southern Australia. Most were clustered 50 - 100 km northeast of Melbourne, capital city of the state of Victoria; yet there were other fires scattered across a wider area as well. The […]

Well, it’s the holiday movie season again. And once again, there’s a sci-fi thriller sure to attract students, The Day the Earth Stood Still. This is a remake of a 1951 movie. That plot involved an alien coming to Earth to warn of nuclear war. The remake has climate change as the demise of the […]

For us humans, especially in urban settings, the seasons come and go with regularity and cause relatively painless changes in our lives — longer days, shorter days, setting clocks forward or backward as we just did. But for most other animal species seasonal changes do not go unnoticed.  Further, when climate change impacts patterns of […]
