Earth is home to many millions of species that have evolved – and adapted or gone extinct – with successive dramatic shifts in climate over the last 500 million years.

The rapid heating of the planet in a climate emergency driven by profligate fossil fuel use threatens a measurable shift in climate conditions and is in any case coincident with what looks like the beginning of a mass extinction that could match any recorded in the rocks of the Permian, or other extinctions linked with global climate change.

The difference is that climate is now changing at a rate far faster than any previous episode. So can those animals that cannot migrate to cooler climates adjust to changing conditions?
