It used to be that you spent staggering sums of public money when something had been proved beyond a scintilla of doubt.
Now these sums are being spent on fashionable theories. What really took the cherry was the bland assertion that although Earth’s surface temperatures were not rising there could well be such dangerous warmings in the deepest parts of the ocean.
Where we don’t have any monitors. So that’s all right then. Fat budgets all round and who needs real evidence?
Certainly not the IPCC.
