“I am troubled by the lack of common sense regarding carbon dioxide emissions. Our greatest greenhouse gas is water. Atmospheric spectroscopy reveals why water has a 95 percent and CO2 a 3.6 percent contribution to the 'greenhouse effect.' Carbon dioxide emissions worldwide each year total 3.2 billion tons. That equals about 0.0168 percent of the atmosphere's CO2 concentration of about 19 trillion tons. This results in a 0.00064 percent increase in the absorption of the sun's radiation. This is an insignificantly small number.”

“The bleak truth is that, under normal conditions, most of North America and Europe are buried under about 1.5km of ice. This bitterly frigid climate is interrupted occasionally by brief warm interglacials, typically lasting less than 10,000 years. The interglacial we have enjoyed throughout recorded human history, called the Holocene, began 11,000 years ago, so the ice is overdue, Chapman wrote. All those urging action to curb global warming need to take off the blinkers and give some thought to what we should do if we are facing global cooling instead.”

“Are global temperatures rising? Surely, they were rising from the late 1970s to 1998, but 'there has been no net global warming since 1998.' Indeed, the more recent numbers show that there is now evidence of significant cooling [...] Mankind is responsible for just a fraction of one percent of the effect from greenhouse gases, and greenhouse gases are not responsible for most of what causes warming (e.g., the Sun).”
