"The planet could cross critical global warming thresholds sooner than previous
models have predicted, even with concerted global climate action, according to
a new study using machine learning.

The study estimates that the planet could reach 1.5 degrees Celsius of warming
above pre-industrial levels in a decade, and found a “substantial possibility”
of global temperature rises crossing the 2-degree threshold by mid-century,
even with significant global efforts to bring down planet-warming pollution.

Data shows average global temperature has already climbed risen around 1.1 to
1.2 degrees since industrialization.

“Our results provide further evidence for high-impact climate change, over the
next three decades,” noted the report, published on Monday in the journal the
Proceedings of the National Academy of Sciences.

Under the 2015 Paris Climate Agreement, countries have pledged to limit global
warming to well below 2 degrees – and preferably to 1.5 degrees – compared to
pre-industrial levels.

Scientists have identified 1.5 degrees of warming as a key tipping point beyond
which the chances of extreme flooding, drought, wildfires and food shortages
will increase dramatically.

Temperature rises over 2 degrees could bring catastrophic and potentially
irreversible impacts, including pushing three billion people into “chronic
water scarcity.”"
