Ice sheets melting, ocean currents, and the risk of climate tipping points
Ice sheets and ocean currents at risk of climate tipping points can
destabilise each other as the world heats up, leading to a domino effect
with severe consequences for humanity, according to a risk analysis.
Tipping points occur when global heating pushes temperatures beyond a
critical threshold, leading to accelerated and irreversible impacts. Some
large ice sheets in Antarctica are thought to already have passed their
tipping points, meaning large sea-level rises in coming centuries.
The new research examined the interactions between ice sheets in West Antarctica,
Greenland, the warm Atlantic Gulf Stream and the Amazon rainforest. The
scientists carried out 3m computer simulations and found domino effects in
a third of them, even when temperature rises were below 2C, the upper limit
of the Paris agreement.
Yhe study showed that the interactions between
these climate systems can lower the critical temperature thresholds at
which each tipping point is passed. It found that ice sheets are potential
starting points for tipping cascades, with the Atlantic currents acting as
a transmitter and eventually affecting the Amazon.
