Reasons for (cautious) optimism: the good news on the climate crisis
There is no shortage of things to say about what’s going wrong. The
extent of damage caused at 1.2C of global heating since pre-industrial levels
is proving greater than was forecast by climate scientists not that long ago.
As discussed last week,
the disastrous toll of the historic flooding in
Pakistan and heatwaves and droughts across the northern
hemisphere summer appear signs of escalation. A peer-reviewed study
found several disastrous climate tipping points, including the collapse of
Greenland’s ice cap and Gulf Stream currents in
the Atlantic Ocean, may now be unavoidable.
But there is also evidence that action to
combat the climate crisis is belatedly accelerating. Acknowledging that every
fraction of a degree of global heating avoided makes a difference, here are
some things to be positive about.
