Hot Blobs – Oceanic geothermal heat

Out of sight, out of mind

What drives ocean heating and global warming? National Academy of Sciences, Engineering and Medicine (NASEM) says in their ‘consensus’ report of Sept. 17, 2025 that global warming is mostly caused by greenhouse gases. This report was issued in rebuttal to the July 23, 2025, report of the Climate Working Group of the US Department of Energy which presented scientific views that carbon dioxide (CO2) has much less effect on climate change than estimated by the UN’s Intergovernmental Panel on Climate Change. These competing climate change reports generated much press and controversy. One part of the NASEM report referred to the ‘blobs’ of ocean heating as being driven by GHGs. Researchers Prof. Wyss Yim and Dr. Arthur Viterito have argued for years that ocean heating is largely affected by subsurface geothermal activity. This video explainer discusses the competing narratives of NASEM and the DOE Climate Working Group, and the implications of the rescission of the US EPA CO2 Endangerment Finding for Canada. Then the video explores Dr. Arthur Viterito’s theory that Mid-Ocean Spreading Zone Seismic Activity (MOSZSA) has a large influential on ocean and global warming.
