You Ought to Have a Look is a feature from the Center for the Study of Science posted by Patrick J. Michaels and Paul C. (“Chip”) Knappenberger. While this section will feature all of the areas of interest that we are emphasizing, the prominence of the climate issue is driving a tremendous amount of web traffic. Here we post a few of the best in recent days, along with our color commentary.
In this week’s YOTHAL edition, we’ll focus on some recent climate science findings that deserve further mention and are worthy of a deeper dive. If and when you have the time and/or inclination, you ought to have a look.
First up is a collection of papers that describe the results of a several experiments looking into cloud formation—or rather, into the availability and development of the aerosol particles that aid in cloud formation. The tiny aerosols are called cloud condensation nuclei (CCN) and without them, it is very difficult for clouds to form.
It’s well known that sulfate particles, formed as a by-product of fossil fuel burning (primarily coal and oil), make for a good source of CCN. In fact, the change in cloud characteristics resulting from this form of air pollution are thought to have asserted a cooling pressure on the earth’s surface temperature—a cooling that has acted to offset a certain portion of the warming caused by the co-incidental emissions of carbon dioxide and other greenhouse gases.
