Humans Already Slowed The Climate Crisis Once, New Research Shows
I hear people saying there is nothing we can do that will change anything. However, we did stop emissions of ozone-destroying class of greenhouse gas called chlorofluorocarbons and we shrunk the ozone hole.
Researchers from the University of New South Wales (UNSW), Australia,
have evaluated various climate scenarios using simulations combined
with a global climate model to judge what our planet might look like if
the 1989 Montreal Protocol had never taken place.
Their initial
goal was to see how a drop in ozone-depleting chemicals affected
atmospheric circulation around the Antarctic. They imagined a world
where CFCs continued to build at around 3 percent each year – a rate
that’s rather conservative given increasing demands of the material
towards the late 20th century.
It’s a world we can be grateful we no longer live in.
