Geothermal heat: an episodic heat source in oceans

Plate climatology (www.plateclimatology.com) is a theory introduced in 2014 by James Kamis.
Unlike the Sun which is the first order driver of earth’s climate, it is an underestimated second order driver which can contribute significantly to regional natural variations. The overall theory contends that periods of active earth tectonics and volcanism can be correlated to periods of active climate change and/or climate related events.

Geothermal Heat and Arctic Sea Ice Variability

Continuing his series of intriguing articles on the effects of volcanic eruptions on regional weather,
Wyss Yim (Geology, 1971-74) has been examining the effect on the extent of Arctic sea ice.

In previous issues of Imperial ENGINEER (Autumn 2013, Spring 2016, Autumn 2016, and Spring 2017), selected volcanic eruptions studied were found to have an important role in regional weather. Out of these, two eruptions releasing geothermal heat into oceans were particularly notable. The first eruption was entirely submarine, and the second eruption was initially submarine followed by both
submarine and sub-aerial activities. Both these eruptions were also responsible for causing the Arctic sea ice to undergo major retreat. In this article, satellite observation records in support of the two retreats are presented, provided by the National Snow and Ice Data Centre, Boulder.
