From Jennifer Marohasy<\/a><\/p>\n\n\n\n

\u00a0By\u00a0jennifer<\/a><\/p>\n\n\n\n

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. \u200b This cooling resulted in a temporary reduction in the rate of increase of atmospheric carbon dioxide (CO2) concentrations. \u200b<\/p>\n\n\n\n

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.  At least that is an important conclusion of a study by my friend and chemist, Bud Bromley.<\/p>\n\n\n\n

Bud\u2019s study demonstrates that the oceans have a tremendous capacity to absorb large amounts of CO2 \u2013 much more than is emitted by humans. \u200b<\/p>\n\n\n\n

This absorption, after the eruption of Mount Pinatubo, was followed by a rapid recovery and acceleration of CO2 levels once the cooling effect dissipated.<\/p>\n\n\n\n

I\u2019m going to be interviewing Bud Bromley next month, specifically at 6pm Hawai\u2019i time on Thursday, 24th<\/sup> April (2pm Brisbane-time the next day, Friday April 25th<\/sup>).  This will be the fourth zoom meeting in my series Towards a New Theory of Climate Change.   If you would like to be a part of this Webinar please register at:<\/p>\n\n\n\n

https:\/\/us02web.zoom.us\/webinar\/register\/WN_QrVa8XEzSPS_GvUWnXkX0Q<\/a><\/p>\n\n\n\n

You will then be sent a confirmation email with a link that you will need to join the webinar, so please file the confirmation email carefully.<\/p>\n\n\n\n

Bud lives in Hawai\u2019i and is a chemist by training.\u00a0 <\/p>\n\n\n\n

He blogs at https:\/\/budbromley.blog\/<\/a><\/p>\n\n\n\n

Bud concluded from this Pinatubo study that human CO2 emissions are not causing the increase in atmospheric CO2. The amount of human CO2 emissions is negligible, less than a rounding error, considering the total carbon budget of the Earth.<\/p>\n\n\n\n

To be sure, Bud is of the considered opinion that contrary to what you have probably read, heard or been taught, the addition of human produced CO2 to the atmosphere by burning natural gas, oil and coal does not increase the global CO2 concentration of the atmosphere. Nor will sequestration of CO2 reduce CO2 concentration in the atmosphere.<\/p>\n\n\n\n

According to Bud, the CO2 concentration in the atmosphere today is the same as it would be if humans never existed.  Ouch.<\/p>\n\n\n

Life goes on in the oceans, and at coral reefs the fish and the corals are more affected by the sea tides that are a consequence of the gravitational pull of the Sun and the Moon.\u00a0 As we develop a new theory of climate change it is important that we have words for describing important processes.\u00a0 Let me suggest that the sea tides be considered external drivers unaffected by occasional events such as volcanic eruptions; such is the nature of external drivers.\u00a0 \u00a0Then there are internal state variables such as temperature that are affected by volcanic eruptions \u2013 and there are feedback mechanisms such that the rate of increase in the atmospheric concentration of carbon dioxide is hardly affected.<\/p>\n\n\n\n

The photograph of me underwater is from Britomart reef in November 2020. I noticed at this reef, as I have been noticing across the bay at the coral reefs fringing Great Keppel Island, that with coral bleaching there can be an expansion in the range of the sea anemones and their clown fish.<\/figcaption><\/figure>\n\n\n\n
