According to the research, the rate of childbirth in the United States spiked by 5% on days when temperatures reached 90 degrees Fahrenheit (32 degrees Celsius).So as the planet warms and days with extreme heat become more frequent, we're likely to see more early births, according to Alan Barreca, the lead author of the study and an environmental researcher at the University of California, Los Angeles.Between 1969 and 1988, an average of 25,000 children were born early every year because of heat - some as much as two weeks early.
Alan Barreca, an associate professor of environmental economics at UCLA's Institute of Environmental Sustainability and author of the study, told Salon he chose to analyze this correlation because Earth is now seeing more intense and prolonged heat waves, and climate models predict they will only get worse. That's the finding of a study published Monday in the journal Nature Climate Change. After temperatures drop, birth rates decrease.
Barreca and a colleague used estimate shifts in daily birth rates from United States counties over a 20-year span, a sample including 56 million births.
"We estimate that birth rates increase by 5% on days with maximum temperatures about 90 degrees Fahrenheit [32.2 degrees Celsius]", the researchers wrote, though the study could not prove that high temperatures actually caused premature deliveries.
"But developed countries, like the United States or England, should pay developing countries for them to electrify with the help of renewable sources, such as wind or solar power., in order to avoid producing more greenhouse gas emissions".

That might sound like a trivial amount of time, but studies show that babies born a week or two early are more likely to develop respiratory issues, higher blood pressure, and neurological conditions. Losing two gestational weeks doesn't shift babies into the "preemie" category, but it could still lead to negative health impacts, Barreca said.A 2017 study revealed that the last two weeks of gestation are critical for the development of babies' lungs. Other research suggests that for newborns and babies in the womb, the damage from heat exposure can persist into adulthood.
While very premature infants face the biggest medical problems, many longitudinal studies show that premature deliveries (born between 34 and 36 weeks) and premature deliveries (37 to 38 weeks) pose a significant risk to survival, growth and development.
The study doesn't explain the connection between extreme heat and earlier births.
Around the world, hot days are getting hotter and more frequent as a result of global warming. Past year was the fourth warmest, behind 2016 (the warmest), 2015, and 2017.July 2019 was the hottest month ever recorded in history.
We know climate change has myriad effects on human health, including an increase in allergies and asthma.
Women are at risk of giving birth early due to warmer temperatures brought on by the climate crisis, a new study finds. First, not all women worldwide have access to air conditioning.
"Some families will experience financial stress even if they are able to use more air conditioning during pregnancy, and financial stress is also bad for children", he said. The earlier a baby is born, the higher the risks of health problems or death.
