Nick Hedley | Five reasons why 2023 is obliterating climate records

In September, the global mean temperature was 1.8°C above the 1850 to 1900 average, and a full 0.5°C higher than the previous monthly record - a margin described by a well-renowned scientist as "absolutely gobsmackingly bananas". But rising temperatures are only a small part of the problem. It's what comes with them that's really concerning, says Nick Hedley.

It's been a record-shattering year for wildfires, floods, heatwaves, storm intensification rates, and ocean and air temperatures.
