A new survey finds that climate-driven extreme heat is increasingly affecting pregnant women and newborn babies across multiple regions. Health professionals interviewed across five continents report having treated women and infants whose health was harmed by high temperatures, as the findings are released ahead of COP31 climate talks.
The UN climate chief, Simon Stiell, is expected to warn at a pre-COP summit in Nadi, Fiji, that rising heat during pregnancy is linked to adverse outcomes. Sources cited include associations with premature birth, stillbirth, low birth weight, and maternal complications. The survey results indicate that more than two thirds of surveyed health professionals have seen heat-related complications over the past five years.
Across outlets, the emphasis is on the growing scale of reported clinical impacts and the role of climate change in intensifying heat extremes. Some reporting frames pregnancy and birth as a vulnerable “fault line” within the wider climate crisis, while other coverage focuses more directly on the specific maternal and newborn risks identified in the survey and attributed to extreme heat.
