"Global warming is crossing dangerous thresholds sooner than expected with the
world’s coral reefs now in an almost irreversible die-off, marking what
scientists describe as the first “tipping point” in climate-driven ecosystem
collapse.
The warning in the
Global Tipping Points report by 160 researchers, which
synthesises groundbreaking science to estimate points of no return, comes ahead
of this year’s COP30 climate summit, the annual gathering of nations to combat
human-induced climate change, being held at the edge of the Amazon rainforest
in Brazil in November.
That same rainforest system is now at risk of collapsing once the average
global temperature warms beyond just 1.5 degrees Celsius, based on
deforestation rates, the report said, revising down the estimated threshold for
the Amazon.
Also of concern if temperatures keep rising is the threat of disruption to the
major ocean current called the Atlantic Meridional Overturning Circulation, or
AMOC, which helps to ensure mild winters in northern Europe.
“Change is happening fast now, tragically, in parts of the climate, the
biosphere,” said environmental scientist Tim Lenton at the University of
Exeter, who is the lead author of the report.
Lenton noted positive signs when it came to phasing out the fossil fuels most
responsible for climate change.
Renewables, for example, accounted for more electricity generation than coal
this year for the first time, according to data from the nonprofit think tank
Ember.
“Nobody wants to be just traumatised and disempowered,” Lenton said.
“We still have some agency.”
The scientists implored countries at COP30 to work toward bringing down
climate-warming carbon emissions."
