Dear Editor:

The National Oceanic and Atmospheric Administration (NOAA) lists some of the effects of climate change.

The world's water resources are diminishing. Less snow accumulating in the West and in Alaska affects water storage. In the Midwest and northeast states increasing heavy downpours have caused flooding and increased problems with water quality.

A local plumber who came to our house last week mentioned that his continued licensing involves attending certification classes. He was told that because of frequent downpours that cause runoff rather than seepage, the ground water in Illinois is decreasing and may become a real problem.

Climate change is affecting our food supply. Increased temperature, diseases and weather extremes affect farming. Flooding has caused millions of dollars in agricultural damage in Iowa and Nebraska. Hogs have drowned, grain has been lost, and many farmers will be unable to plant in the spring.

Human health is affected by global warming, which increases water-borne diseases.

The ocean absorbs 30 percent of the carbon dioxide released by the burning of fossil fuels. This has caused the ocean to become more acidic, affecting marine life and thus our food supply.

Rising sea levels are caused by melting glaciers and ice sheets.

A report released in January by researchers in the United Kingdom (the University of East Anglia) has found a strong link between climate change, conflict and migration. Looking at asylum applications for 157 countries between 2006 and 2015, the report found that in many cases, warming-related drought sparked conflicts that sent refugees abroad.

If David Hanson calls all this only "a perceived threat," he's sticking his head in the sand.

David says I "ignore the effects and esthetics of covering millions of acres of land with solar cells." points out that 21,250 square miles of solar panels would supply enough electricity to power the country. That's a space of 145 miles on each side, or one-half of one percent of U.S. land. Meanwhile, 33,750 square miles are set aside to grow ethanol, and 40,223 square miles are now leased by the oil and gas industry.

From an editorial in the March 6 New Yorker, on line: "We are racing toward — in fact have already entered — an era of water shortage, wildfire, sea-level rise, and extreme weather."

There is no Planet B.
