In the wake of recent scandals in climate science, many people seem to have forgotten that unambiguous evidence for climate change is everywhere: including in the changing locations of species. The locations of thousands of species have been tracked, including plants, animals, and insects. Since 1950, they have been moving northward at a rate of about 6.5 kilometres per decade. Meanwhile, the lines denoting regions with a given temperature range (isotherms) have been shifting north at 56 km per decade. Gardeners and birdwatchers can tell you that the climate is changing.
A colony of Galapagos sea lions have migrated 1,500 km. Meanwhile, other plants and animals are moving poleward and uphill. When species get pushed to the edges of continents or the top of mountains, they will be in grave danger. Likewise, when animals are forced to move northward faster than the plants they depend on can do so, it strains food webs.
Say what you will about the personal conduct of climate scientists, the evidence of a changing climate is everywhere. Hopefully, human beings will understand this and begin to curb it before too many species are pushed to the wall, and before our own becomes too threatened.
