“There is no climate emergency.” April 16, 2021

“We are both scientists who can attest that the research literature does not support the claim of a climate emergency. Nor will there be one. None of the lurid predictions —dangerously accelerating sea-level rise, increasingly extreme weather, more deadly forest fires, unprecedented warming, etc. —are any more accurate than the fire-and-brimstone sermons used to stoke fanaticism in medieval crusaders.”

“True believers assert that this emergency can be averted only by eliminating greenhouse-gas emissions. Greenhouse gases include ubiquitous water vapor, methane, nitrous oxide, and above all, carbon dioxide, a gas released when fossil fuels are burned to power transportation, generate electricity, and are used to manufacture amenities of modern life.“

“Greenhouse gases in the atmosphere let sunlight warm the earth’s surface. But they absorb some of the heat radiation from the surface and atmosphere that would otherwise cool more efficiently by escaping directly to space. Greenhouse gases —and clouds —keep the earth’s surface temperature several tens of degrees Celsius warmer than it would be without them.“

So far, climate crusaders have refrained from vilifying water vapor and clouds, which make the largest c”ontribution to greenhouse warming of the earth. Carbon dioxide, demonized as “carbon pollution,” is an improbable villain. Green plants use the energy of sunlight to manufacture sugar and other organic molecules of life from carbon dioxide and water molecules. A byproduct of photosynthesis is the oxygen of our atmosphere. Each human exhales about two pounds of the ‘pollutant’ carbon dioxide every day.”

“No scientist familiar with radiation transfer denies that more carbon dioxide is likely to cause some surface warming. But the warming would be small and benign. In fact, history shows that warmings of a few degrees Celsius —which extended growing seasons—have been good for humanity. The golden age of classical Roman civilization occurred during a warm period. Cooling periods, which were accompanied by barbarian invasions, famines, and plagues, have been bad. Barbara Tuchman characterizes such periods as‘the calamitous 14th century in her book, A Distant Mirror.“

“More carbon dioxide will certainly increase the productivity of agriculture and forestry. Over the past century, the earth has already become noticeably greener as a result of the modest increase of CO2, from about 0.03 percent to 0.04 percent of atmospheric molecules. More CO2 has made a significant contribution to the increased crop yields of the past 50 years, as well. The benefits to plants of more CO2 are documented in hundreds of scientific studies.”

“There is no climate emergency. Americans should not be stampeded into a disastrous climate crusade. The medieval crusades did far more harm than good, destroying the lives of many decent people of all faiths, and leaving a bitter legacy that complicates international relations and social harmony to this day. A climate crusade that destroys economies and ultimately lives will be as bad, or worse.”
