Earth Sense: A few simple steps can save energy

Energy is expensive, and yet it gets wasted all the time. For example, observe drivers on our mountainous roads. Many use their brakes going uphill, when it would have been sufficient to just step off the gas pedal and let gravity slow the car to the desired speed.

Earth Sense: Food supply, overconsumption a growing problem

Earth Sense: Snow is as iffy in North Ga. as it is in Bethlehem

Pretty Christmas cards with snow-laden New England landscapes are arriving. The desert town of Bethlehem, birthplace of Christ 2,000 years ago, is located 6 miles south of Jerusalem in today's West Bank in the Palestinian Territory. It probably didn't look like Bangor, Maine, back then, and it doesn't now.

Earth Sense: Warm oceans can bring Arctic blasts howling South

A week ago, a winter storm brought record low temperatures to the Western states. Cold outbreaks aren't uncommon there in early December, but the severity of the chill amazed forecasters and the general population alike.

Earth Sense: Flooding is dangerous for Central European residents

When Germany's Elbe River flooded in May this year, Hamburg and other communities along the waterway felt reminded of the catastrophic storm flood of February 1962. I remember TV images of people clinging to rooftops that were the only portions of houses still above the water.

Braselton hospital a model for green construction

Back in the 1950s, most hospitals were eerie places: Tiled walls, dimly lit hallways, gruff personnel. It would be tough to find such an old-style, stark facility in this country today.

Earth Sense: Volcanic calamities may be just a tick away

The Pacific "Ring of Fire" is living up to its name again. After some rumblings in October, Mount Sinabung on the island of Sumatra (Indonesia) erupted with ash falls and lava flows last week. Five-thousand people were forced to flee the surrounding areas.

Earth Sense: Killer, powerful storms are part of a worldwide pattern

In 1520, when Ferdinand Magellan's little fleet emerged from the storm-whipped straits of the tip of South America into a vast ocean to the west, it seemed so peaceful to him that he named it "Pacific Ocean."

Earth Sense: Right bulbs, driving habits can save energy

Colder weather is here, and we use more energy for lighting and heat. Even the car burns more gas when it has to start up at low temperatures. But it's also a time when we can realize energy savings. If you're still using the old-fashioned "Edison" incandescent bulbs, you're wasting electricity.

Earth Sense: Keeping an eye on the shade

In these times of terrorist attacks, the appearance of an "Urban Forest Strike Team" may raise concerns in some people's minds. But this particular task force has a purpose that's entirely in the interest of Georgia communities.

Earth Sense: Tornadoes don’t always follow patterns

People in Iowa, Nebraska and South Dakota aren't unfamiliar with tornadoes. But during the night of Oct. 4, well outside severe weather season, a dozen strong tornadoes ripped across the Great Plains.

Earth Sense: Severe quakes are common in Pakistan

Recently, southwestern Pakistan was rocked by a 1-2 punch of major earthquakes. The first one Sept. 24 had a magnitude of 7.7. For comparison, the Loma Prieta Quake which struck the Santa Cruz-San Francisco, Calif., area in 1989 was a 6.9. That was sufficient to collapse parts of Interstate 880, burying motorists beneath concrete. On the Bay Bridge, an entire section disengaged, causing cars to fall into the gap.

Earth Sense: Why we need old-growth forests

If you take a trip to the Blue Ridge Parkway this season to watch the leaves turn color, you'll be treated to nice views. But much of the wooded countryside consists of second-growth forest, following long periods of attempts to farm the land. In the Eastern U.S., reserves of old-growth forest have become small and are threatened by logging and development. Some estimates indicate that our old-growth inventory has shrunk to 10 percent of what it was in the 1600s.

Continental air drift will bear teeth

There's no room for doubts when the weather forecast calls for "100 percent chance of precipitation." Such was the case on the last day of summer, Sept. 21. An enormous cold front stretched a line of clouds and rain showers from its southernmost point, the State of Michoacan in central Mexico, to Killiniq Island. That's the northernmost tip of Quebec and Labrador, 4,000 miles from Mexico City.

Earth Sense: When unexpected heavy rains occur, move to higher ground

Superstorm Sandy, which covered the East Coast with floodwaters from Florida to Maine in 2012, is still a household name. But memories of Sandy were overshadowed by the torrential rains that hit Baltimore, Long Island and Connecticut on Aug. 12.
