A reminder that climatology isn’t an exact science:
A Russian scientist predicts a period of global cooling in coming decades, followed by a warmer interval.
Khabibullo Abdusamatov expects a repeat of the period known as the Little Ice Age. During the 16th century, the Baltic Sea froze so hard that hotels were built on the ice for people crossing the sea in coaches.
To paraphrase Michael Crichton, if weather forecasters can’t get it right more than 12 hours in advance, why should we believe they can predict what the Earth’s climate will be 50 years from now?
In other words, short of trying not to add pollutants to the air, any attempts to modify the weather on a global scale is probably grounded in assumptions based on insufficient information.
