Hydrothermal vents may contribute more to the thermal budget of the oceans than previously assumed

“This could change our understanding of the contribution of hydrothermal activity to the thermal budget of the oceans. Our discovery is also exciting because it could provide the answer to a long standing mystery: We do not know how animals travel between the large hydrothermal vents, which are often separated by hundreds to thousands of kilometres from each other. They may be using these smaller sites as stepping stones for their dispersal.”
Fascinating insights and videos from the Max Planck Institute. The existence of similar vents round antarctica has to be worthy of more investigation. Ever since I have been studying so-called "anthropogenic global warming" I have wondered about the amount of the input into our "greenhouse" of the earth's own "central heating".
When I have raised this question on occasion it has been dismissed as derisory but I think it is just another of those climatic variables that gets dismissed in the rush to blame CO2 for all the "residual" warming we cannot currently explain by any other mechanism. Until we know the impact of the earth's own natural temperature variability (the "known unknowns") we cannot begin to estimate the role of other possible sources of warming.
Whereas the earth's hot core has co-existed alongside "snowball earth" conditions when the entire surface has been ice-covered it MUST have some measureable impact!
