Timewatch

In 1783, thousands in Britain died as a result of an environmental disaster, choking on poisonous gases from a huge volcanic eruption in Iceland. The ensuing winter was one of the harshest ever recorded and claimed even more lives. This forgotten disaster has remained a mystery for the past 200 years. 'Timewatch' reveals the evidence and reviews the likelihood of a repetition.
