Climate extremes seen harming unborn babies in Brazil's Amazon

A new study that links extreme rains with lower birth weights in Brazil’s Amazon region underscores the long-term health impacts of weather extremes connected to climate change, researchers said on Monday. Exceptionally heavy rain and floods during pregnancy were linked to lower birth weight and premature births in Brazil’s northern Amazonas state, according to the researchers from Britain’s Lancaster University and the FIOCRUZ health research institute.
