Extreme heat is posing increasing risks to pregnant women and newborns, UN climate chief Simon Stiell has warned. He cited a survey of 1,000 midwives and doctors in the UK, Australia, India, Brazil, and Zimbabwe, commissioned by the Wellcome Foundation. More than two-thirds of these health professionals reported seeing complications caused by intense heat in the past five years. About a third of respondents noted cases of low birth weight, restricted growth, feeding difficulties, or dehydration resulting from extreme heat.
Stiell stated that rising temperatures mean rising danger in pregnancy, calling pregnancy and birth a new 'fault line' in the global climate crisis. Scientists note that climate change is intensifying extreme weather events. An analysis of data from the European Union's Copernicus climate observatory indicated that approximately 33 countries experienced their hottest July on record this year.
Disagreement on specific figures
One report stated that each one-degree Celsius rise in temperature contributes to a 5% increase in premature births and a 7% increase in gestational diabetes cases, according to data from a new study. This specific figure was not mentioned in other reports.
What the coverage left out
None of the left-rated digests mention the specific figure that each one-degree Celsius rise in temperature contributes to a 5% increase in premature births and a 7% increase in gestational diabetes cases, which was present in one right-rated digest.

How each side covered it
Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.
Left
12 rated outlets
- Left-rated reports highlighted that pregnant women and newborns are bearing the brunt of global warming but are being forgotten, with campaigners calling for action. Several reports focused on the UN climate chief's warning that pregnancy is a new fault line in the climate crisis, with one mentioning that women with 'no cool place to go' face rising risks. The finding that nearly all maternity workers surveyed had treated patients they believed were harmed by extreme heat was also noted.
Centre
13 rated outlets
- Centre-rated reports led with the UN climate chief's warning that extreme heat is putting pregnant women and newborns at risk. They frequently cited the survey finding that 73% of maternal healthcare workers had seen heat-linked cases rise in the last five years. The fact that around 33 countries recorded their hottest July on record this year, according to EU Copernicus data, was also a common point.
Right
8 rated outlets
- Right-rated reports focused on the UN's alert that extreme heat threatens the safety of pregnancy and birth. They mentioned that the UN warns extreme heat from climate change increases risks during pregnancy, including premature birth, infant death, low birth weight, and maternal complications. One report noted that high temperatures could increase multiple risks, ranging from premature births to the death of the newborn and congenital malformations.

- Neither side dominates it. Of the 33 rated outlets on this story, 36% are rated left, 40% are rated centre, 24% are rated right, and no side holds the 70% this site would want before calling a field one-sided.

- Is the coverage of UN climate chief warns extreme heat risks pregnancy biased?
- UN climate chief warns extreme heat risks pregnancy is one event reported by 51 outlets, and this page does not rate the story as biased or unbiased.
