Thousands of Species Are Fleeing to Earth's Poles En Masse, a Pattern's Emerging

This sent chills down my spine.

We don't have much time left.

We know that global warming is forcing many animals around the world to flee their normal habitats, but now, an exhaustive analysis has shown marine species are booking it for the poles six times faster than those on land.

Drawing together 258 peer-reviewed studies, researchers compared over 30,000 habitat shifts in more than 12,000 species of bacteria, fungi, plants, and animals.

The resulting database, named BioShifts, is the first comprehensive analysis of its kind, and while the database is limited by our own, human research biases, the data we have certainly suggests marine species are following global thermal shifts much closer than land animals.

In the review, amphibians were found to be moving up slope at over 12 metres a year, while reptiles seem to be headed towards the equator at 6.5 metres a year.

Insects, which incidentally carry many diseases, were found to be moving poleward at 18.5 kilometres per year.

Relatively, that's a lot, but in the bigger picture, marine species were moving towards the poles at an average pace of nearly 6 kilometres per year, while land animals were only shifting upslope at a mean pace of nearly 1.8 metres per year (slightly faster than previous estimates for land species, but still comparatively slow).
