What we really have here is strong La Nina running on over 6 months now, combined with a Cold PDO and weakly active sun running on over 6 years. Those are the present conditions. Not last years average atmospheric temp. The atmosphere temps have been falling and are right now close to normal. Only two decent hot spots in shallow ocean water right now and they are no where near Australia or Brazil. Right now there are no El Nino effects and no Global Warming effects possibly occurring during the actual flooding.
My second cup of coffee got cold. Proof positive that there is anthrowarming.
