Rothamsted Temperature Record - Atmospheric Sulphur to Blame?
Rothamsted Research Sulphur (pdf) gives us a simple graph showing the decrease in Atmospheric Sulphur (No apologies to my valued American visitors, that is how we spell Sulfur!)
I have previously blogged about how Rothamsted shows a marked increase in minimum temperature compared to other UK sites, and that it probably was the one most affected by the decrease in smoky chimneys. (Woburn is 25 miles north west of Rothamsted and is an outlying station.)
As the amount of Sulphur rose in the 1970s we would expect it to be cold, and as the air is cleaned up starting in the 1980s we would expect it get warmer. The UK sulphur emissions have continued to fall according to official figures mirroring the rise in Rothamsted's minimum temperature.
So why do we not hear more about this huge change in atmospheric pollution, a pollution that the consensus is causes lower temperatures, and vastly more about a much smaller change in the CO2 levels?
