Apart from the impact on the environment, increasing use of air conditioning (AC) could have social and political effects. A new paper by researchers from the University of California, Berkeley and the University of Mannheim set out to understand the relationships between climate, income and residential air conditioning. Their model suggested that wider use of AC will save lives that would otherwise be taken by heartstroke or the exacerbation of other health conditions — 550,000 a year by 2050 in India alone — but it will disproportionately benefit those with higher incomes. Poorer people without AC are more likely to be less productive or to die than those who can afford it. Heat hinders learning and lowers test scores, causing poorer children to fall behind. And the use of AC itself contributes to global warming, making life even hotter for everyone.
