The World Wide Web is loaded with information tools, but for anyone interested in the natural environment, Google Earth has to rank among the best. A simple search makes it quick to find and download. After starting the program, try putting some place names or coordinates into the search box at left.
Does anybody have a yearning for the "Good Old Days" to return - say, the 1960s? We drove around in cars with no seat belts. In a lightning storm, we were told to lay face down in a ditch (never mind the 12,000 gallons of water that might come rushing down on us).
It could happen here in Georgia.
As we prepare to start a new year, we can also expect to find ourselves in a changed world. The old dream of living off the land in a quiet cottage is giving way to an ever-increasing worldwide trend: the megacity.
In the debate about rising atmospheric CO2 levels, it's rarely mentioned that there's a host of unknown factors. That's not a reason to lay back and continue business as usual.
The 2012 climate conference in Doha, Qatar, on the Persian Gulf concluded without strong measures to control carbon dioxide emissions.
The simplest form of airplane flight is found in the glider. It uses only pockets of rising air, and the movement of air past its wings, to fly above the surface.
In places where there are water-related problems, engineering is often touted as the solution. As an example for what happens when you tinker with natural waterways, the river Rhine in Germany, often visited by Americans, stands out.
The water discussions in the Gainesville and Atlanta areas often bring up the term "drainage basin," which is the same thing as a "watershed."
With so many changes going on in our natural environment, you may be wondering what to expect in the months ahead. An earthquake in Guatemala 10 days ago killed 48, and another severe one happened in Myanmar last Sunday.
It gets dark an hour earlier now than it did last month. As we head for the shortest days of the year, outdoor and indoor lighting are very important.
It's rare for a hurricane like Sandy to bypass most of the East Coast and then enter the continent that far north.
Fall is the season for enjoying colors in North Georgia. But it's not just the colors of tree leaves that are changing. The sky shows a much greater variety of hues than we get at other times of the year.
In this country, the automobile is the most common form of transportation. You don't need to go far to observe the problems that come with it.
Sunshine. Then more than 6 inches of rain, setting an all-time record for Gainesville. Then sunshine again.
The March 22 mudslide in Oso, Wash., raises the question whether something like this could happen here. It's not likely, because we don't have the deep soil that led to the Western disaster.
Late spring and early summer are some of the best times to visit Europe, especially the Upper Rhine Valley.
The magnitude 5.1 earthquake that occurred around midnight on March 29 east of Los Angeles was a reminder of the unstable geologic conditions in Western states. Its epicenter was in a densely populated residential area of La Habra, Calif., just a quarter-mile from Sonora High School.
