[MCN] We must avoid 5C heating, or risk annihilation of everything we take for granted

Aug 6, 2018 ... Even if the Paris agreement is successfully implemented, the planet could still heat up by 5 degrees Celsius, scientists warn.

The magazine article quotes the scientists:

“Our study suggests that human-induced global warming of 2 degrees Celsius may trigger other Earth system processes, often called 'feedbacks,' that can drive further warming — even if we stop emitting greenhouse gases.” 

And:
“These tipping elements can potentially act like a row of dominos. Once one is pushed over, it pushes Earth toward another. It may be very difficult or impossible to stop the whole row of dominoes from tumbling over.”

“I just want it to be clear that the mainstream environmental movement has been asking very little of people for decades,” said Bea Ruiz, also an organizer with the U.S. national [ Extinction Rebellion ] team. “There’s no element of, ‘We are in an emergency. We all need to do more than what we’re doing.”

A recent Ambio article by some heavyweights in climate sets out the situation well enough. 

A team including the likes of Will Steffen, Paul Crutzen, Veerabhadren Ramathan, Johan Rockstrom, Marten Scheffer and Hans Joachim Schellnhuber begin the abstract of their article by saying “Over the past century, the total material wealth of humanity has been enhanced …”  

They end it saying,“we risk driving the Earth System onto a trajectory toward more hostile states from which we cannot easily return.”

Their analysis is echoed across the scientists side of the situation. But it doesn’t take a scientist to get the drift of what’s going on. 

Liam Denning is former investment banker, former editor of one of the Wall Street Journal’s most closely read columns —Heard on the Street — and a former columnist for Financial Times. Writing about the Green New Deal for Bloomberg, Denning has come to the conclusion that, “We have built our standard of living on forms of energy that we now know pose a threat to our very existence,” and that, “this is a conversation that is long overdue — and necessarily begins with a shout, not a whisper.”
