"Deforestation and other fast-moving changes in the Amazon threaten to
turn parts of the rainforest into savanna, devastate wildlife and
release billions of tons carbon into the atmosphere, two renowned
experts warned Friday.
“The precious Amazon is teetering on the edge of functional destruction
and, with it, so are we,” Thomas Lovejoy of George Mason University and
Carlos Nobre of the University of Sao Paulo in Brazil, both of whom have
studied the world’s largest rainforest for decades, wrote in an
editorial in the journal Science Advances. “Today, we stand exactly in a
moment of destiny: The tipping point is here, it is now.”
Combined with recent news that the thawing Arctic permafrost may be
beginning to fill the atmosphere with greenhouse gases, and that
Greenland’s ice sheet is melting at an accelerating pace, it’s the
latest hint that important parts of the climate system may be moving
toward irreversible changes at a pace that defies earlier predictions."
