Why Hasn’t The Earth Warmed In Nearly 15 Years?

There is no statistically significant warming trend since November of 1996 in monthly surface temperature records compiled at the University of East Anglia. Do we now understand why there’s been no change in fourteen and a half years?

If you read the news stories surrounding a recent paper in the Proceedings of the National Academy of Sciences by Boston University’s Robert Kaufmann and three colleagues, you’d say yes, indeed. It’s China’s fault. By dramatically increasing their combustion of coal, they have increased the concentration of fine particles in the atmosphere called sulphate aerosols, which reflect away solar radiation, countering the warming that should be occurring from increasing atmospheric carbon dioxide.

Climate alarmists are now explaining away their failed predictions by claiming China’s power plants emit sulfur dioxide that cancels out carbon dioxide emissions. So should we burn more coal?

Among the emails unearthed during ClimateGate, when scientists working at or with Britain’s Climate Research Unit conspired to “hide the decline” in global temperatures, is one from Kevin Trenberth of the National Center for Atmospheric Research to Michael Mann, inventor of the now-discredited “hockey stick” graph that purported to show sudden and dangerous man-induced temperature rise.

Economists ride into sulphurous cloud of aerosols

By Andrew Orlowski

The refusal of the global temperatures to rise as predicted has caused much angst among academics. “The fact is that we can’t account for the lack of warming at the moment and it is a travesty that we can’t,” wrote one in 2009. Either the instruments were wrong, or the heat energy had gone missing somewhere.

Now a team of academics, after tweaking a statistical model to include sulphur emissions, suggest that coal power stations may be to blame for a lack of global warming since 1998. The IPCC’s 2007 assessment acknowledged the negative radiative forcing (aka, cooling effect) of both natural aerosols from volcanoes and manmade aerosols, but admitted the level of scientific understanding was low.
