This week evolutionary ecologist Peter Mayhew has presented a set of findings which show the rate of climate change in the Earth to be detrimental to the number of species of animals on our planet. While findings in the past have shown that periods of warmth on our blue globe have also been times when the number of different species of animals has risen, the speed at which the Earth is warming here in the present is, as Mayhew suggests, too rapid for the increase in species to outweigh the number of species that are becoming extinct. The new study Mayhew presents works with a new way of looking at the number of species in each geological period studied with only well-sampled periods rather than with simple tallies of the first and last appearances of each species.
