June warmest on record; every month since July 2023 breached 1.5°C threshold

At the 2015 UN climate talks in Paris, world leaders committed to limiting the global average temperature rise to 1.5 degrees Celsius above the pre-industrial period to avoid the worst impacts of climate change. However, a permanent breach of the 1.5-degree Celsius limit specified in the Paris Agreement refers to long-term warming over a 20 or 30-year period.
