Global warming may have other causes

On May 8, Nevada County had high ozone levels. The United States has high greenhouse gases. Yet, when indications of global warming are reported, they take place in the polar regions. These places have no greenhouse gas production.

The 1930s Dust Bowl had mammoth dust storms. In the 1940s, New York City had terrible pollution levels. The Kuwait oil fires produced immense amounts of greenhouse gases. The air in Los Angeles is filled with smog. Thousands of volcanic eruptions have produced vast amounts of gases. No global warming disasters resulted.

Our Earth has a hot core. The Earth’s temperature increases one degree Fahrenheit for every 60 feet of depth. The core is estimated at 3,000 to 5,000 degrees centigrade. This heat is in evidence when volcanoes erupt and geysers and hot springs produce steam and boiling water.

Earthquakes are evidence of below-ground movements. Underlying plates are believed to have moved continents great distances. Below-ground disturbances may alter surface temperatures. This may be the cause of melting ice on the Earth’s surface. This may be the cause of global warming.
