Climate change will be the “largest factor to human extinction,” according to an end-of-the-world warning.
Scientists have warned that if humans do not address the climate crisis, the end of the world as we know it could be just around the corner.
It comes less than a month after the UN’s Intergovernmental Panel on Climate Change (IPCC) declared climate change a “code red” for humanity. They warned of more catastrophic heatwaves, droughts, and flooding, as well as the breaking of a crucial temperature boundary in just over a decade. Experts have now sketched a dismal picture of humanity’s future.
Scientists warn that ignoring the climate crisis will cause humanity “untold agony.”
They claim that, while climate change will not directly cause extinction, it will play a significant role in triggering social breakdown and setting the stage for world conflict, such as through causing food and water scarcity.
“There’s no need to overestimate the climate threat,” said Michael Mann, a prominent professor of atmospheric science at Penn State University. The truth is awful enough to justify taking drastic measures.”
Professor Mann believes that a 3°C rise in global temperature would result in the collapse of our society infrastructure, as well as widespread instability and conflict.
One way this could be manifested is through the creation of food insecurity.
Warming the earth has a number of negative consequences for food production, including increasing the water deficit and, as a result, diminishing crop yields.
Luke Kemp, a research associate at the University of Cambridge, is interested in historical civilisation collapses as well as the threat of climate change.
He told Live Science that extinction events nearly typically involve numerous variables, but he believes that climate change would be the primary cause if humanity went extinct.
“If I had to say, what do I believe is the biggest contributor to the possibility of human extinction in the future?” he said. Then there’s climate change, without a doubt.”
All major mass extinction events in Earth’s history, according to the expert, have entailed some type of climatic shift.
This includes the Ordovician-Silurian extinction, which wiped out 85 percent of species around 440 million years ago, and the Triassic-Jurassic extinction, which destroyed 80 percent of species around 200 million years ago.
“While Homo sapiens is clearly not gone, we do have a history of other hominid species going extinct, such as Neanderthals,” Mr Kemp added.
“And in each of these circumstances, it.”
