Professor Ole Humlum, formerly of the University of Oslo, Norway points out that new data on rising ocean temperatures raise interesting questions about the source of the heat. “We can detect a great deal of heat rising from the bottom of the oceans. This obviously cannot be anything to do with human activity. So although people say the oceans are warming, in reality there is still much to learn.”
'Since 1979, Arctic and Antarctic sea-ice extents have had opposite trends, decreasing and increasing, respectively.'
'Tropical storms and hurricanes...no overall trend towards either lower or higher activity. The same applies for the number of continental hurricane landfalls in the USA, in a record going back to 1851.'
"Northern Hemisphere snow cover extent...since 1972, however, snow extent has been largely stable."
Rahmstorf: "The comparative study by researchers from the University of Exeter now shows that in particular the warming since 1975 – i.e. most of the modern global warming – is clearly too strong in the sensitive models. More recent analyses by ETH Zurich, for which more models have already been evaluated, confirm this conclusion. This is a reason to breathe a sigh of relief: there is currently some evidence that these models are not better than the old ones, but are simply too sensitive."
