Climatologist Dr. Roy Spencer 'There is no Climate Crisis. There is no Climate Emergency. Yes, irregular warming is occurring.'
Deep Ocean Warming Could Be Mostly Natural: A related issue is how much the deep oceans are warming. As I have mentioned before, the (inarguable) energy imbalance associated with deep-ocean warming in recent decades is only about 1 part (less than 1 Watt per sq. m) in 300 of the natural energy flows in the climate system. This is a very tiny energy imbalance in the climate system. We know NONE of the natural energy flows to that level of accuracy. What that means is that global warming could be mostly natural, and we would not even know it.
A well-defined ocean warming trend originating off the United States East Coast is likely from super-heated and methane-enriched fluids emitted from numerous seafloor hydrothermal vents/hot springs (see figure 1 after the jump).
Supporting evidence: This trend has shown up on shallow Sea Surface (SST) maps since their advent in 1997 and has likely been present for thousands of years.
