Analysing data for over 2000 responses by animal and plant species


Analysing data for over 2000 responses by animal and plant species, scientists estimated that, on average, species have moved to higher elevations at 12.2 metres per decade and, more dramatically, to higher latitudes at 17.6 kilometres per decade.

Birds, mammals, reptiles, insects, spiders, other invertebrates, and plants featured in the evidence.
