"The growing threat of abrupt and irreversible climate changes must
compel political and economic action on emissions.
Politicians, economists and even some natural scientists have tended to
assume that tipping points1 in the Earth system — such as the loss of
the Amazon rainforest or the West Antarctic ice sheet — are of low
probability and little understood. Yet evidence is mounting that these
events could be more likely than was thought, have high impacts and are
interconnected across different biophysical systems, potentially
committing the world to long-term irreversible changes.
Here we summarize evidence on the threat of exceeding tipping points,
identify knowledge gaps and suggest how these should be plugged. We
explore the effects of such large-scale changes, how quickly they might
unfold and whether we still have any control over them."
