7 October

This is the second US hurricane in a fortnight. The reason is the same reason Australia has been so wet in the past 2 years. The oceans are boiling. Water in the Gulf there is 1-3 degrees hotter than normal. That doesn’t sound a lot, but that’s confusing temperature with heat. Heating that enormous mass of water by only a degree (temperature) is an *enormous* amount of heat (energy) that needs to go somewhere.
