Jim Massa debunks another DeNile claim against abrupt global warming: Volcano heating of the oceans

 Jim someone just posted this reply to me so I dared them to post it on your channel and told them I would repost it here for you to reply to. Here you go: "also the heat in the ocean isn’t only caused by atmospheric chemical reactions. 9/10 it is more likely to be caused by geothermal activity on the ocean floor. For example I find it funny you make reference but I looked up the nasa reference you claimed and it literally mentioned that volcanic activity is the leading cause to the ocean temperature as more volcanic activity has occurred within the last 20 years than they ever had in centuries."

The great majority of volcanic activity is found at hydrothermal vents. yes, that water is super heated when it emerges and stays liquid due to the immense pressure. It also travels horizontally and quickly cools down. Any heat plumes that do rise soon bend horizontally. The heat contained does not reach depths shallower than 2000 m. Volcanic activity is typically at the plate boundaries. Same situation. Heat is quickly dispersed, cold water temps and very high pressure keeps the heat in the abyssal depths. On the rare occasion when a volcano's eruption is strong enough to send hot material through the entire water column, the impact to overall water temp is not significant. What must be remembered is the ocean heat found at depths up to 700 m down. What is the overriding source of that heat? It is not volcanism. It is GHG.

 @ScienceTalkwithJimMassa  Thanks Jim! I was reading Kevin Phillip's 2008 book on US Empire and the financial crisis - he mentioned Kivalina village in Alaska, and the New Yorker notes two years ago - it's one of 73 Alaskan native villages facing imminent disappearance due to abrupt global warming. It's kind of insane this doesn't get much mention in the corporate-state media. I guess the "lower 48" pretty much ignores Alaska though. haha. Oh yeah last night I listened to Neil Turok, this astrophysicist, and he mentioned how it was due to early life on the planet that creates a layer of graphite on the ocean floor, thereby enabling loss of friction to CREATE the first mountains on Earth from plate tectonics subduction! I never knew about that connection of early life creating a layer of graphite to reduce the friction enough of subduction!

 

 specific minerals (so called“fault lubricants”) such as chrysotile [Moore et al., 1996], smectite (montmorillonite)[Moore and Lockner, 2007], and talc [Moore and Lockner,2008] have low coefficients of friction (m≤0.2) underwater-saturated conditions when compared with most rock-forming minerals.
