I read El Reg frequently for their IT articles but only for fun on other topics where, IMHO, "misrepresentation" and "The Register" are synonymous.
Regarding the article in question, here's what the scientific paper concluded (I obtained a copy of the paper and verified this myself):
Quote:
Over the last 30-years temperatures in other tropical ocean
basins have been rising steadily, but at a slower rate than the
Atlantic (31). At the same time projections of surface
temperature increases under a doubled carbon dioxide climate
suggest that the Atlantic should be warming at a rate slower
than the other observations (32). We suggest this apparent
disconnect between observations and models may be due to
the influence of Atlantic dust cover. Our results imply that
since dust plays a role in modulating tropical North Atlantic
Ocean temperature, projections of these temperatures under
various global warming scenarios by general circulation
models should account for long-term changes in dust
loadings. This is especially critical as studies have estimated a
reduction in Atlantic dust cover of 40-60% under a doubled
carbon dioxide climate (33), which, based on model runs with
an equivalent reduction of the mean dust forcing, could result
in an additional 0.3-0.4°C warming of the northern tropical
Atlantic.
