A recent study published in *Nature* warns that the escalating use of air conditioning worldwide is poised to exacerbate climate change significantly by 2050. This increase is attributed to the corresponding rise in greenhouse gas emissions from AC units. The research presents various climate scenarios, suggesting that while emissions could peak before 2040 under aggressive climate mitigation efforts, they are more likely to continue climbing until 2050. The study's baseline scenario forecasts a jump in AC-related GHG emissions from 1.3 GtCO2eq in 2010 to 3.8 GtCO2eq in 2050. The most alarming projection, under the SSP585 scenario, estimates emissions could soar to 8.5 GtCO2eq.
