Air conditioning and other cooling systems are widely recognized as integral to protecting people from the sometimes deadly impacts of extreme heat, which are intensifying in step with climate change.

Yet according to a study, published yesterday in Nature Sustainability, there remains a “global blind spot” when it comes to handling the already exorbitant demand for cooling and indoor air conditioning, which alone is projected to triple by 2050. That’s a stark reality, the report warns, given that many cooling systems are carbon-intensive—and contribute to global warming themselves.
