What is this? Bone heads anonymous??? It's possible for cold water to be significantly warmer than average, while still being very cold for humans to swim in. I reckon your average 5 year old could get their head around that concept. Anyway, if you are capable, think about how much energy it takes to increase the temperature of an ocean a couple of degrees. If you want, you can give me your answer in terms of number of nuclear power plants. (Hint: it's a big number)

It can take none in actual fact if the change is simply due to current direction changes and or eddies - on a large scale as has been documented b CSIRO in the past for different areas.Will a monster eddy current off the coast of Sydney bring a new marine heatwave? (unsw.edu.au) Over the past month, an enormous eddy – fully 400km wide and 3km deep – has been spinning up just off southeastern Australia. It’s being fed by the warm East Australian Current, which brings warm water from the tropics down to more temperate waters. This eddy is bigger and warmer than most eddies in the region, especially at this time of year. It has been growing over the past month, and is pushing up against cold waters to the south. Where the two systems meet there are very strong temperature differences – up to 5°C over just 4km.
You can get some insight into how.
Some of us can think for ourselves rather than be led by coloured pictured designed to fool the kids.
