The greenhouse energy effect. Of all the fundamentals that are factored into the science of climate change, this is one that stands at or near the top in importance because of its direct bearing on changes in Earth’s surface temperatures. … Continue reading →

I want to write some more about the greenhouse effect of precipitable water (PW), comparing it to the greenhouse effect produced by CO2 and a number of other gases. The effect is always produced in the same basic way—by any … Continue reading →

Some readers may notice the appearance of a new policy template in the upper right corner. It represents my feeling that the current practice of this science is not fully in tune with the workings of nature, or what we … Continue reading →
