An opinion piece by RICHARD LINDZEN& WILLIAM HAPPER for Nation Reviews' Capital Matters (link) contains this statement:
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.
NOTE: ....the warming would be small and benign...
And what if we add more CO2?
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 CO, from about 0.03 percent to 0.04 percent of atmospheric molecules. More CO has made a significant contribution to the increased crop yields of the past 50 years, as well. The benefits to plants of more CO are documented in hundreds of scientific studies.
So warming is small and benign and the increased CO2 causes increased crop yields...
Well worth a read of the whole article from two excellent scientists who
can attest that the research literature does not support the claim of a climate emergency. Nor will there be one.
