Earth Sense: Old safety tips are best left in the past
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).
Earth Sense: Exploring caves can be fun, but dangerous
It could happen here in Georgia. A cave enthusiast was crawling through a narrow passage, along with others. He decided to take a side turn and explore a particularly tight tunnel, 16 inches wide and 10 inches high. As the tunnel began to descend, he slid down a distance and got stuck.

Earth Sense: Changing river’s flow has drawbacks

The water discussions in the Gainesville and Atlanta areas often bring up the term "drainage basin," which is the same thing as a "watershed."
Earth Sense: Cold fronts will begin to change our weather
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.
Earth Sense: LED bulbs might be best alternative
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.
Earth Sense: Preparation for hurricane is vital
It's rare for a hurricane like Sandy to bypass most of the East Coast and then enter the continent that far north.
Earth Sense: Colorful fall skies determined by moisture
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.
