Humankind is facing an imminent threat of extinction, according to new research released on Wednesday by the science journal Nature. The report Approaching a state shift in Earth’s biosphere reveals that our planet's biosphere is steadily approaching a 'tipping point', meaning all ecosystems are nearing sudden and irreversible change that will not be conducive to human life.
The authors describe what they see as a fast paced 'state shift' once the tipping point is reached, which contrasts with the mainstream view that environmental change will take centuries. "It's a question of whether it is going to be manageable change or abrupt change. And we have reason to believe the change may be abrupt and surprising," said co-researcher Arne Mooers, a professor of biodiversity at Simon Fraser University in Canada's British Columbia.
