Covid lockdowns had a significant impact on carbon dioxide emissions. But not on the annual rate of increase as measured at Mauna Loa, because the increase is from natural sources. Shhh.
The amount of carbon in the oceans is significant, and the extent to which the oceans breathe out carbon dioxide makes human emissions somewhat insignificant when all the data is considered. I will be discussing all of this with a chemist, who actually lives in Hawaii, where atmospheric levels of carbon dioxide are measured at Mauna Loa. If you would like to be a part of this webinar, the next in my series Towards a New Theory of Climate Resilience, then consider registering. It will be at 2pm Friday 25th April my time, which is 6pm the day before in Hawaii. You can register at:
How Climate Works, Part 3. The Eruption of Mount Pinatubo with Bud Bromley
Date & Time
Apr 25, 2025 12:00 AM
Description
The volcanic eruption of Mount Pinatubo in June 1991 led to a significant cooling of the tropical ocean surface due to the cloud belt formed by the eruption. This cooling resulted in a temporary reduction in the rate of increase of atmospheric carbon dioxide (CO2) levels. Despite ongoing human CO2 emissions and natural sources of CO2, the cooling effect caused by the volcanic aerosols led to a rapid absorption of CO2 by the ocean, that is an important conclusion of a study by my friend and chemist, Bud Bromley. It demonstrates the ocean’s capacity to absorb large amounts of CO2 – much more than is emitted by humans. This absorption was followed by a rapid recovery and acceleration of CO2 levels once the cooling effect dissipated.
