Patrick Moore (“10,000 years ago? That was climate change. Today? Not so much’’) does not support the notion of climate change.

Research does not support Moore’s position.

However, if one hesitates to accept global climate change, it is prudent to proceed with caution when making decisions that affect global political, economic, agricultural, and security issues. This caution could be called “Look before you leap’’ or the “precautionary principle.’’

Let’s explore ways that society can replace old and inefficient 19th-century power sources, such as coal and oil. Let’s pursue short-term nuclear investments and solar, wind, geothermal, tidal, and other alternative power sources, along with new technologies and devices, that are more energy-efficient.

Investments in distributed energy production sites, using efficient and sustainable methods, can be placed closer to end users. Think of it as neighborhood production. Let’s install rooftop solar collectors, not to provide 100 percent of energy that’s needed, but rather, a percentage that local producers won’t need to make. These technologies could provide the industrial jobs our country needs for the future.

If climate change is shown to be a mistake, consider how much better off can we be with the replacement of old, economically wasteful industries by more efficient, economic, and environmentally sustainable operations?
