Record global temperature in 2023 helps reveal acceleration of global warming on decadal time scales. The proximate cause of the acceleration is increase of Earth’s energy imbalance, specifically a substantial darkening of the planet (decreased albedo) equivalent to a CO2 increase of more than 100 ppm, although it is difficult to apportion the albedo change between aerosol forcing and cloud feedbacks because of limited global measurements. Large 2023 warming is consistent with key findings in Global Warming in the Pipeline:[3] reduced aerosol cooling and high climate sensitivity. We expect record monthly temperatures to continue into mid-2024 due to the present large planetary energy imbalance, with the 12-month running-mean global temperature reaching +1.6-1.7°C relative to 1880-1920 and falling to only +1.4 ± 0.1°C during the following La Nina. Considering the large planetary energy imbalance, it will be clear that the world is passing through the 1.5°C ceiling, and is headed much higher, unless steps are taken to affect Earth’s energy imbalance.
