From the climate files: British researchers have discovered that a species of microscopic plankton is migrating back to the North Atlantic, more than 800,000 years after its extinction in the region.
This is good news, you might be thinking; but, the shift is likely due to warming ocean temperatures and melting polar ice. And though the plankton is a food species, its return is not being welcomed, as it signals changes at the base of the marine food chain that could have harmful consequences for other species.
