Scientists are analysing the striking sunsets painted by Turner and dozens of other artists to work out the cooling effects of huge volcanic eruptions. By working out how the climate varied naturally in the past they hope to improve the computer models used to simulate global warming. The team, at the National Observatory of Athens, is using the works of old masters to work out the amount of natural pollution spewed into the skies by eruptions such as Mount Krakatoa in 1883.
