As Los Angeles burns the World has crossed the 1.5C threshold

The highly destructive wildfires in Los Angeles US, in January 2025 are a warning to the World at large of the threat posed by climate change and its impact. Similar fires have been seen in the Mediterranean during their Summer period with similar devastating effects particularly in Greece.

The Copernicus Institute summarised the situation thus:  

“2024 saw unprecedented global temperatures, following on from the remarkable warmth of 2023. It also became the first year with an average temperature clearly exceeding 1.5°C above the pre-industrial level – a threshold set by the Paris Agreement to significantly reduce the risks and impacts of climate change. Multiple global records were broken, for greenhouse gas levels, and for both air temperature and sea surface temperature, contributing to extreme events, including floods, heatwaves and wildfires. These data highlight the accelerating impacts of human-caused climate change”.

Key points -

• 2024 was the warmest year in a multi-dataset record of global temperature going back to 1850.
• 2024 had a global average temperature of 15.10°C; 0.12°C higher than the previous highest annual value in 2023.
• 2024 was 0.72°C warmer than the 1991–2020 average, and 1.60°C warmer than the pre-industrial level, making it the first calendar year to exceed 1.5 above that level.
• The last ten years have been the warmest ten years on record.
• Each month from January to June 2024 was warmer than the corresponding month in any previous year. August 2024 equalled the record warmth of August 2023 and the remaining months from July to December were each the second warmest for the time of year, after the corresponding months in 2023.
• On 22 July 2024, the daily global average temperature reached a new record high of 17.16°C.
