let’s cleanse our minds of the bias of the climate alarmists…WSJ readers

We should waste little time and energy worrying about possibility of humans having a significant effect on our climate. But if we want something to worry about, consider what our government officials plan to do about this imagined problem. They insist that we quickly wean ourselves from the use of carbon containing fuels (coal, oil and natural gas) that emit CO2, that dangerous “greenhouse gas” that causes global warming. These fuels have proven to be efficient and environmentally acceptable for many years, but must now be supplanted by costly, subsidized, inefficient, intermittent and distantly located non-carbon methods such as windmills and solar panels. Furthermore, serious thought is being given to control CO2 emission selectively from exhaust gases from coal fired power plants, a concept from far left field. Mr. Ridley makes a strong case, based on unbiased science, showing that this benign and necessary-for-life component of our atmosphere is really not capable of producing significant climate change. So, what to do?

First, let’s cleanse our minds of the bias of the climate alarmists, including the Intergovernmental Panel on Climate Change, and then start to understand how our climate really works. A host of natural forces have produced wild variability over the centuries. The current fad of ascribing local, severe weather events to imagined climate change such as global warming is largely a waste of time.

Mr. Ridley correctly notes that carbon dioxide is not the only “greenhouse gas” that can affect climate and that water vapor is also a key factor. He explains that “a little warming (from whatever cause)” heats the oceans and makes the atmosphere more humid and that such humidity including cloud formations affects climate.

Global warming alarmists have put the cart before the horse. Higher levels of the trace gas, carbon dioxide, are a byproduct, not a cause, of global warming brought about by infinitely more powerful cosmic forces. It is a travesty to blame humankind for global warming and to deny us the power of fossil fuels, which will be essential to protect, feed and relocate large populations should natural forces beyond our control continue to raise sea levels.
