ANTHROPOGENIC Global Warming (AGW) theory is currently the most fashionable climate theory and its proponents have risked much by predicting a continuation in what has been a 150-year general warming trend.
There are already some indications this trend is stalling with no increase in average global atmospheric temperatures for 15 years [1].
For those who subscribe to any one of the many theories that purport to explain natural climate variability the stakes are not so high: whichever way temperatures swing we can claim to be right. Indeed simply claiming that climate change is natural does not constitute a theory amenable to falsification.
There has been some arguing recently over ocean temperatures, in particular heat content, and how it is trending. I am happy to concede the AGW proponents might have one remaining residual warming trend to cling to here.
