With an El Niño on the way, 2013 could be the warmest year on record. But the climate-denial machine will keep on churning

IT HAS been another "normal" global-warming summer in the northern hemisphere. The US sweltered in the hottest July on record, following the hottest spring on record. More than 60 per cent of the contiguous US is suffering from drought, as are parts of eastern Europe and India. In the Arctic, sea ice cover is at a record low and the Greenland ice sheet shows what the US National Snow and Ice Data Center calls "extraordinary high melting". Global land temperatures for May and June were the hottest since records began in the 19th century.

Meanwhile, El Niño conditions are forecast to develop in the tropical Pacific Ocean, warming up ocean surface temperatures. Some observers have predicted that this will lead to record-breaking global temperatures next year.

If El Niño does arrive and temperature records are broken, there will inevitably be much discussion of the causes of the warming. So now is a good time to sort signal from noise in the global temperature records.


For the past 30 years, global temperature has shown a linear warming trend of 0.16 °C per decade (Environmental Research Letters, vol 6, p 044022). When looking for the cause of this warming, a physicist will look for the heat source. One possibility is that the oceans are releasing heat. But measurements show the opposite: the oceans are soaking up heat. The other possibility is that the heat is coming from above, and indeed it is: more radiation is entering the top of the atmosphere than leaving it. This is because increasing amounts of greenhouse gases in the atmosphere hamper the loss of heat into space.

BTW another "Scientific" Editor has let "name calling" (deniers) be a normal way to describe people who don't agree with "man made" climate change....and what do I think of so call scientific publications who promote this view........they should be removed from the label of scientific status.
