It’s massively concerning that, although scientists seem to understand why the earth has been warming due to climate change over the last few decades, they don’t seem to know why there’s all of a sudden been a huge spike.

I just hope it’s not something like methane being released from permafrost, because then we are all completely shafted.

Chart showing huge spike in temperature
Global temperatures soared to a new record in September by a huge margin, stunning scientists and leading one to describe it as “absolutely gobsmackingly bananas”.

The hottest September on record follows the hottest August and hottest July, with the latter being the hottest month ever recorded. The high temperatures have driven heatwaves and wildfires across the world.

September 2023 beat the previous record for that month by 0.5C, the largest jump in temperature ever seen. September was about 1.8C warmer than pre-industrial levels. Datasets from European and Japanese scientists confirm the leap.

The heat is the result of the continuing high levels of carbon dioxide emissions combined with a rapid flip of the planet’s biggest natural climate phenomenon, El Niño. The previous three years saw La Niña conditions in the Pacific Ocean, which lowers global temperature by a few tenths of a degree as more heat is stored in the ocean.

The scientists said that the exceptional events of 2023 could be a normal year in just a decade, unless there is a dramatic increase in climate action. The researchers overwhelmingly pointed to one action as critical: slashing the burning of fossil fuels down to zero.
