Ten years ago, the world committed itself to keeping global warming well below 2°C (and preferably below 1.5°C) above the pre-industrial era. This would be done by reducing greenhouse gas emissions significantly by 2030 and ending all human-caused greenhouse gas emissions by 2050. This was the time of promises, with 195 countries signing up to the legally binding, global treaty on climate change, the Paris Agreement.
Ten years on, however, the climate crisis is more urgent than ever. According to the United Nations:
The first 12-month period to exceed 1.5°C as an average was February 2023–January 2024, boosted by El Niño, when the average temperature worldwide was estimated to be 1.52°C higher than 1850–1900.
