“We have to realize how big this thing is,” Gore said about Hurricane Harvey. “We have got to change.”
In the unsurpassed weather event for our lifetime, Harvey’s nearly 25 trillion gallons of water ravaged southeast Texas and Louisiana over the course of a week, totaling more than 51 inches in some places. It is estimated 13 million residents endured some type of flood watch or warning, and the storm displaced as many as 30,000 people, many of whose homes and businesses were utterly destroyed. But is man’s activity on earth causing it? Many climatologists point to the floodplain of Buffalo Bayou itself, the main artery of moving water out of a nearly sea-level Houston as proof that Houston has been flooding like this for thousands of years.
Warm air tends to hold and deposit more moisture. Slow moving storms that either sit or move to the warm Gulf of Mexico, restrengthen and come back as in 2001’s tropical storm Allison are the most devastating. All scientists agree that a warmer climate brings stronger storms, but are humans causing that warmer climate through CO2 emissions as claimed by Al Gore?
One look at the topography of Houston and the width of the bayou itself shows how it was carved out by the normal variance of climate change over thousands of years. In fact, the scar of the Earth shows major shifts in the building up of topography through ice ages and the deepening of gouges caused by major flooding more likely from warmer climates and more intense deluges. Ice core samples in the coldest areas of the Earth show our planet has been warming and cooling dramatically since the Big Bang built this third rock from the Sun.
Sometimes geology provides answers the skies cannot.
