ACIDIC GAS CLOUD ENGULFS UK SKIES
Brits have been warned to stay inside as a cloud of corrosive and acidic gas, which can cause serious health problems, covered the UK.
Weather maps showed a massive cloud of sulfur dioxide (SO2), spat out by the recent volcanic eruptions in Iceland, completely covering the country.
SO2 is predominantly produced from the combustion of coal or crude oil, but volcanoes also produce vast quantities of it when they erupt.
Inhaling the gas can cause symptoms such as a sore throat, coughing, a runny nose, burning eyes, tight lungs, and difficulty breathing.

Not sure where this article is from but there are many in the comments from the UK saying there is nothing in their skies.
The gas may be invisible in the upper atmosphere.
If it is in the upper atmosphere then it will whizz past. However, it is heavier than air, so doubt on the upper atmosphere thing - it will come down.
They used to tell us that when it rained it would be acid rain.
