Ocean surface water temperatures are up due to AGW.
Unsubstantiated opinion.
Jo Nova says: The alarmists have abandoned air temperatures as a measure of global temperature, because the air temperature graphs are just too hard to argue with (like the second figure below, from the Skeptics Handbook). Instead they’ve switched to ocean temperatures, which they often disguise as ocean heat content (a huge number like 15×10²² Joules sounds much more scary than the warming it implies of 0.003° C/year).
I've never heard that humidity was rising but fresh water is becoming a valuable resource.
