More than 90% of the world’s population is projected to face increased risks from the compound impacts of extreme heat and drought, potentially widening social inequalities as well as undermining the natural world’s ability to reduce CO2 emissions in the atmosphere — according to a study from Oxford University’s School of Geography.
In the wake of record temperatures in 2022, from London to Shanghai, continuing rising temperatures are projected around the world. When assessed together, the linked threats of heat and drought represent a significantly higher risk to society and ecosystems than when either threat is considered independently, according to the paper, published this month in the journal Nature Sustainability.
