Ten Grim Climate Scenarios If Global Temperatures Continue to Rise

The summer of 2018 was intense: deadly wildfires, persistent drought, killer floods and record-breaking heat. Although scientists exercise great care before linking individual weather events to climate change, the rise in global temperatures caused by human activities has been found to increase the severity, likelihood and duration of such conditions.

Globally, 2018 is on pace to be the fourth-hottest year on record. Only 2015, 2016 and 2017 were hotter. If humankind carries on its business-as-usual approach to climate change, there’s a 93 percent chance we’re barreling toward a world that is 4 degrees Celsius warmer by the end of the century, a potentially catastrophic level of warming.

In 2017, more than 15,000 scientists from 184 countries co-signed their names to an updated — and even bleaker — version of a 1992 manifesto that predicted depletion of freshwater sources, overfishing, plummeting biodiversity, unsustainable human population growth. All are even worse now.

“We have unleashed a mass extinction event, the sixth in roughly 540 million years, wherein many current life forms could be annihilated or at least committed to extinction by the end of this century.”

But they stressed that, “Soon it will be too late to shift course away from our failing trajectory, and time is running out.”

See what could happen…
