The frightening expectation…a supercomputer warns of a “mass extinction” on Earth

Australian and European scientists have developed a “virtual Earth” to simulate global extinctions that will take place Climate changeduring this century.

The results indicate that 10 percent of all plant and animal species will be lost by 2050. The figure will rise to 27 percent by the end of this century..

Scientists blamed “resource over-exploitation, land-use change, over-harvesting, pollution, climate change and biological invasions,” according to the British Daily Mail.

The study was led by European Commission scientist Giovanni Strona and Professor Corey Bradshaw of Flinders University, Australia.

The researchers said thatPlanet Earth already entered into an event mass extinction Sixth, driven by human activity and climate change..

According to the International Union for Conservation of Nature’s Red List, there are more than 42,100 species threatened with extinction..

Bradshaw said: “Children born today could witness the virtual disappearance of thousands of plant and animal species by the time they reach the age of 70, from tiny orchids and the smallest insects to iconic animals like The elephants And thekoalas“.

and using “supercomputerScientists have created a world with more than 15,000 “food webs” to predict the fate of interconnected organisms. They said that the tool “can map extinctions everywhere on Earth,” noting that it “predicts a bleak future for global diversity, which confirms beyond measure.” There is no doubt that the world is in the throes of the sixth mass extinction..

They indicated that previous methods for evaluating trajectories extinction over the next century was “flawed” because it “didn’t include common extinctions.”.

Co-extinction is when a species becomes extinct because other species that depend on it “subject to climate change or changes in their habitat.”.

In this regard, Bradshaw explained: “Think of a predatory species (animals) losing prey to climate change. Or you can simply imagine that pests are losing their host due to deforestation, or a flowering plant is losing ‘pollinators’ to the heat.”

Co-extinction is now recognized as a major contributor to loss Biodiversity global, strongly amplifying the impact of primary factors such as climate change.

For the study, they hypothetically showed that species are linked to “who eats whom,” and then applied climate and land use changes to make future predictions..

“The model does not produce an exact replica of the Earth, but instead aims to construct an ecologically reasonable Earth,” the team explained.

Strona said: “We mobilized A virtual world From the ground up, we have predicted the fate of thousands of species (from objects) across the globe, to determine the likelihood of real-world turning points“.

We can then assess adaptation scenarios different climatic conditions, and correlations with other factors, to predict the co-extinction pattern..

It should be noted that the study was published in “Science Advances”It comes as the 2022 United Nations Conference on Biodiversity takes place (COP15) in Montreal, Canada.

The two countries agreed a landmark deal to protect nature, pledging to secure 30 percent of the planet as a protected area by 2030..
