On this programme a few minutes ago David Attenborough said that sea
temperature over the Australian Great Barrier Reef are much higher than
normal this year. The present temperature anomaly maps don't agree with
this. For example see

Overall, an interesting programme but I worry about the number of
scientists that appear on such programmes making very positive
pronouncements that certain changes "will" occur as a result of global
warming rather than "may" occur. Nothing is certain until after it has
occurred. And what about the inevitable changes that no-one has even
thought about yet. Have the very complex feed-back loops been adequately
modelled. I am no expert on this but it's such a complex subject that I
find it very difficult to believe that the modelling is free from
significant flaws.
