"In 2023, we saw a raft of news stories about climate tipping points, including
the accelerating loss of Greenland and Antarctic ice sheets, the potential
dieback of the Amazon rainforest and the likely weakening of the Atlantic
Meridional Ocean Circulation.

The ice sheets, Amazon rainforest and the Atlantic ocean circulation are among
nine recognised global climate tipping elements. Once a tipping point is
crossed, changes are often irreversible for a very long time. In many cases,
additional greenhouse gases will be released into the atmosphere, further
warming our planet.

New scientific research and reviews suggest at least one of Earth’s “tipping
points” could be closer than we hoped. A milestone review of global tipping
points was launched at last year’s COP28.

What will these tipping points mean for Australia? We don’t yet have a good
enough understanding to fully answer this question.

Our report, released overnight, includes conclusions in three categories: we
need to do more research; tipping points must be part of climate projections,
hazard and impact analyses; and adaptation plans must take the potential
impacts into account."
