Next time the heavens open and you curse yourself for leaving your brolly at home, be grateful you're not living in the Triassic period, when it rained non-stop for two million years.
This is just one of the fascinating insights into our planet's history explored by Chris Packham in this flagship BBC series.
In the first episode, Inferno, we travel back 253 million years, to the late Permian period, one million years before the biggest mass extinction the globe has ever seen, 'the Great Dying', which marks the end of the Permian period and the beginning of the Triassic.
