The first breach of 1.5°C will be a temporary but devastating failure

The world has already warmed by about 1.2°C since pre-industrial times.
Within the next four years, there is a 48 per cent chance temperatures
could breach the 1.5°C threshold for the first time, according to the UK
Met Office.

At most, the world has nine years until breaching 1.5°C for at
least one year is inevitable, according to the Global Carbon Project. It
would be a totemic milestone. The 1.5°C target has become a guiding light
for the climate movement, after it was included as a “stretch goal” in
the 2015 Paris Agreement.

In the document, the world’s nations promise to
limit any global rise in average temperatures to “well below” 2°C and
to strive for warming of no more than 1.5°C. That inclusion of 1.5°C in
the agreement – fought for by campaigners and small island states at risk
of rising seas – focused scientific minds.

In 2018, the Intergovernmental
Panel on Climate Change published a report on the projected impact of
exceeding the 1.5°C target, which warned that warming beyond this level
would be far more damaging than first thought.
