Thousands of species fled to the Earth's poles because of the warming climate

Global warming is forcing many animals around the world to flee from their normal habitats. But according to a complete analysis, marine species are fleeing six times faster than terrestrial species.

According to research published in Nature Ecology & Evolution, the scientists combined 256 studies that were peer reviewed and compared more than 30,000 changes to the habitat of more than 12,000 species of bacteria, fungi, and bacteria. animals and animals.

The database named BioShifts is the first comprehensive analysis on this issue. Data show that marine species are monitoring global thermal change more closely than terrestrial animals.

The authors said that terrestrial species are moving closer to the poles as the planet heats up "at a much slower rate than expected, especially in regions with warm climates."

Amphibians are found moving up the slope at a height of more than 12 meters per year, while reptiles are heading towards the equator at 6.5 meters per year. Insects are found moving at 18.5km / year.

In general, marine species are moving toward the poles with an average speed of nearly 6 km / year, while terrestrial animals only move upwards at an average speed of nearly 1.8 meters / year.

This difference between land and aquatic animals can exist for many reasons. This is probably due to temperature sensitivity, the air conducts heat 25 times less efficient than water, and many terrestrial animals can easily adjust their body temperature if desired.

In addition, domestic animals can move a lot easier if needed. On land, human activities often hinder the movement of animals.

"On land, habitat loss and fragmentation due to land use change may hinder the ability of terrestrial species to monitor shift isotherms' , the authors write.

According to scientists, these complex interactions need to be calculated to improve the biodiversity redistribution scenarios and their consequences for human health under future climate change. .

If the authors get it right, and marine life is watching the temperature change more closely, it can have profound and profound consequences.

As temperatures rise, marine creatures enter a narrower habitat range and cause them to swim towards the poles, which also threatens to deplete the cold water.

The same thing is happening on land. Animals found on high mountains are believed to be riding "escalators to extinction" as temperatures and competition push them to the brink. Just in the country, this 'escalator' seems to be moving faster.

However, the meta-analysis used to create the BioShifts database includes only 0.6% of known life on earth and the studied animals tend to be most attractive or important to human, concentrated mainly in the northern hemisphere.

So the scientists admit to calling this a global meta-analysis , but it's not.

'We can only work with what we have, and it seems that the animals we know are struggling to find new habitats in the face of a growing climate crisis.

And BioShifts is a way for us to help track those changes to predict what will happen next, ' the authors said.
