The temperature of deep oceans is set by the temperature of the water under
the Arctic and Antarctic ice which has not changed. The temperature of ice is
still 0C despite AGW. Surface temperatures, where any rise in global
temperatures would be noticed first, have been measured and do show an
increase. The concentration of carbon dioxide in the atmosphere has also been
measured since 1960 and it also shows an increase. The only problem is why
temperature has not increased as fast as CO2, but the atmospheric temperature
rise is probably being delayed by the heat capacity of the oceans.
Cheers, Alastair.
