Mother Nature continues to try to convince the climate change naysayers how wrong they are and how frightful and expensive global warming is becoming.
The latest example is the massive tornado that destroyed more than half of a Nebraska town about 100 miles northwest of Omaha. Several people were injured Monday and at least two were killed when the tornado hit in Pilger.
The National Weather Service reported that at least two tornadoes struck within a mile of each other.
Human use of fossil fuels continues to create greenhouse gases, warming the planet. Polar ice is melting, putting more moisture in the air and generating more horrific storms.
People are having to contend with the cleanup after tornadoes like the one that hit Pilger. But there are also more violent hurricanes, longer droughts and accompanying fires.
Switching to renewable energy sources such as solar, wind and geothermal have to be a mandate for humanity. Otherwise, people will have to brace for more unpredictable and disastrous weather.
