[MCN] Quick rant: Trade/travel and pandemics past, present, future

[Lance Olsen]

Trade/travel played key role in the Black Plague, the so-called “Spanish” flu, and today’s sprawl of coronavirus. Trade/travel is very likely to play an equally decisive role in the pandemics yet ahead.

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

The lead authors say:

“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.”
