The 'Exceptional' 2007 Drought

The American Southeast should not look as it does. Rows of cypress trees lining the streets are dead and brown. Lawns, which should be a brilliant green, are dry and withered. Streams, ponds, and lakes are all down several feet from their normal water levels. The clear, blue sky, once so beautiful in forecasting a bright, sunny day, has become unwelcome all across the parched South, from Alabama and Tennessee, through Georgia, to North and South Carolina. Parts of all five of these states are experiencing what the U.S. Drought Monitor calls a D4 or "exceptional" drought.

The Drought Monitor's producers—a partnership of the U.S. Department of Agriculture, the National Weather Service's Climate Prediction Center, the National Climatic Data Center, and the National Drought Mitigation Center at the University of Nebraska Lincoln—describe D4 drought conditions as "exceptional and widespread crop/pasture losses; shortages of water in reservoirs, streams, and wells creating water emergencies." It is the most intense category of drought—expected only once every one hundred years—and obviously the most difficult from which to recover. A "normal" amount of rainfall in subsequent years will not refill reservoirs and water tables to pre-drought levels.

Northern Georgia lies in the center of the exceptional drought area. In late August, 70 of the state's 159 counties were under the exceptional condition, and with continued hot and dry weather, additional counties are expected to be added to the list. According to the University of Georgia College of Agricultural and Environmental Sciences:

Soil moisture is near the 1st percentile across most of west and north Georgia. At this level, we would expect the soil to be moister in 99 of 100 years. Most streams across west and north Georgia are at or near record low flows for late August. The Chattooga River in the northeast mountains is approaching an all-time record low flow. The stream gage data for the Chattooga goes back 67 years.

In the next few months, "the best hope"—the University's term—for relief from the dire drought is from tropical weather systems, that is, tropical storms or hurricanes. Absent such an event or two, the outlook for the fall and winter is grim. In addition, long-range forecasts predict a drier, warmer winter for the U.S. Southeast.

Lake Lanier, the main reservoir for the city of Atlanta and its five million area residents, has received national media attention, both for its record low levels and the fact that it also supplies water to northern Florida, where certain endangered mussel species and sturgeon face a heightened threat due to the water scarcity. By law, Georgia must release 3.2 billion gallons of water per day downstream to fill Florida's hydroelectric needs as well as to preserve its wildlife.

Georgia Governor Sonny Purdue argues that, since water supplies have slipped under the three-month threshold, water outflows from Georgia need to be reduced, and Florida counties should place businesses and residents under water restrictions. The well-being of people, he declares, should take precedence over endangered fish. His point becomes even weightier, if, as it is expected, the director of the Georgia Environmental Protection Division, Carol Couch, recommends tightened water restrictions for the Atlanta area, which may include mandatory cutbacks on commercial and industrial users. If they are implemented, these water restrictions would be the most severe in the history of U.S. metropolitan areas.

Biblically, drought has long been seen as a sign of God's displeasure with His people. Both of the "blessing and cursing" chapters (Leviticus 26 and Deuteronomy 28) include drought among the curses for disobedience. For example, God says in Leviticus 26:18-20:

And after all this, if you do not obey Me, then I will punish you seven times more for your sins. . . . I will make your heavens like iron and your earth like bronze. And your strength shall be spent in vain; for your land shall not yield its produce, nor shall the trees of the land yield their fruit. (See Deuteronomy 28:23-24.)

Amos 4:6-8 illustrates God's use of drought—and the resulting famine—as a prod to induce repentance, a method of persuasion that Israel rarely heeded:

"Also I gave you cleanness of teeth in all your cities, and lack of bread in all your places; yet you have not returned to Me," says the Lord. "I also withheld rain from you, when there were still three months to the harvest. I made it rain on one city, I withheld rain from another city. One part was rained upon, and where it did not rain the part withered . . . yet you have not returned to Me," says the Lord.

In this modern, scientific age, we tend to consider droughts like the current one to be merely extremes of the meteorological cycle. Yet, God is sovereign over His creation, and He is still at work among the descendants of His people Israel. With its extensive exposure to Christian principles, the modern nations of Israel should know what God expects of them in their conduct, but America, Britain, Canada, Australia, and the other Israelite countries have increasingly ignored God and His way. As a result, their cultures have become secular, greedy, and self-indulgent.

It should be no wonder, then, that such a broad swath of the United States is experiencing this exceptional drought. Will the citizens of America's Bible Belt return to God? If not, what worse disasters can be expected in the future?

Storm of the Century

Over the past two days, more than fifteen inches of snow fell on south Charlotte where I live, encasing everything in a thick, crystalline blanket. My house, topped with more than a foot of white stuff, looks like some mad, Southern imitation of a Courier and Ives picture, even to the wisps of smoke escaping from the chimney. Sadly, the old, grey car parked in my driveway in no way resembles the ubiquitous sleigh in those wintry illustrations.

Statistically, this weather system produced the storm of the century for the region. The Charlotte area—which averages about one snowstorm a year, and that of only a few inches—had not received this much snow at once since 1902. In this metropolitan area of more than a million people, a frozen deluge like this one brings everything to a slippery halt, since the city owns only two-dozen trucks that can be used for salting and plowing the roads. According to the city fathers (and mothers), its money is better spent on building an arena for billionaire Robert "Bobcat" Johnson and implementing an unnecessary light-rail system. No amount of money is too much to spend to make Charlotte a "World-Class City"! Meanwhile, they warn that our dire financial circumstances warrant future tax increases.

Children love days like this. For starters, they are out of school, even my home-schooled kids. There is no sense making them slog away at the books when all their neighborhood friends are out sledding (down my driveway, of course), throwing snowballs at each other (from behind their newly constructed "forts"), eating snow (either inadvertently from a snowball in the face or deliberately), carving snow angels (and—mothers love this—getting soaking wet in the process), and building snow men (and women). On days like these, our clothes dryer gets a good workout, as each kid comes in at least twice to disrobe, go to the bathroom, grab a snack, and don a new set of warm clothes for the next go-round. In the meantime, Mom loads the dryer to be prepared for their inevitable return to repeat the process.

Dogs enjoy days like this too—at least my dog, Sydney, does. She is a black Labrador Retriever-Border Collie mix, but her genes seem heavy on the Lab part. In the snow, stark black against the glistening white, she is in her element (Labrador Retrievers were developed in Newfoundland). Even though the snow had piled higher than her back, she was game, bounding over the drifts as a dolphin hurdles the waves. She ate the snow just as much as the boys did, and then she was back to racing among them and trying her best to involve herself in their games.

Around here, though, the fun of a snowstorm is over all too quickly. The temperatures rarely remain cold enough for the snow to linger very long. Two days, maybe three, and the snow has melted, making the ground sodden and in some places muddy. The pristine glitter and excitement of freshly fallen snow give way to a big, wet mess.

Certainly, the city cannot remain under the spell of a rare snowfall for more than a day or so. Parents have to get back to the old grind, businesses need to make their profits, and government must return to spending its citizens' money profligately. The supermarkets need to restock their bread and milk, and the hardware stores must reorder batteries, snow shovels, and space heaters. And the snowplow drivers, electrical linemen, and emergency workers need a little time off—not to mention the intrepid meteorologists.

I have learned one lesson from this massive, once-in-a-century storm: As technologically advanced as we are, as much as we claim to have conquered nature, it is an empty boast. The forces involved in something this huge are far beyond mankind's ability to influence, much less control. This storm should give even the environmentalists pause in their wrong-headed push to convince us that man has caused global warming.

It reminds me of what God said to Job to cut him down to size: "Have you entered the treasury of snow, or have you seen the treasury of hail, which I have reserved for the time of trouble, for the day of battle and war?" (Job 38:22-23). Or, what David said to God, "What is man that You are mindful of him? And the son of man that You visit him?" (Psalm 8:4). We are so puny, and if it takes the storm of the century to make this point, then it is a good thing. Fun too.
