Rising temperatures around the world as a result of climate change are having a devastating effect on foetuses, babies and infants, studies have found.

Scientists from six different studies determined that climate change is causing – among other adverse outcomes – the increased risk of premature birth, increased hospitalisation of young children and weight gain in babies.

The separate studies have just been published in a special issue of the journal Paediatric and Perinatal Epidemiology.

The journal’s guest editors Professor Gregory Wellenius and Professor Amelia Wesselink from the Boston University School of Public Health said that a growing body of evidence indicates the ways in which extreme heat, hurricanes and wildfire smoke can increase the risk of pre-term birth.

One of the studies found that pre-term births were 16% more likely in areas experiencing heatwaves.

Researchers did this by looking at one million pregnant women between 2004 and 2015 in the high temperature region of New South Wales Australia.

Similar findings were observed in a study that assessed the link between ambient heat and spontaneous pre-term birth between 2007-2011 in the hot climate of Harris Country, Texas.

The day after mothers were exposed to heatwave temperatures, their risk of premature birth was 15%.

Another study in the journal which analysed 200,000 births in Israel found links between high temperature and weight gain during the first year of life. Of the 20% exposed to night-time temperature, 5% had a higher risk of rapid weight gain.

An accompanying study found that as the frequency and intensity of wildfires have increased dramatically over the past two decades in the western US, there had been a 32% rise in a rare condition typically associated with air pollution among pregnant women.

Foetal gastroschisis is an abdominal wall defect that is rare, but “increasing in prevalence,” according to Prof Wellenius and Prof Wesselink.

Writing in the special edition of the journal which looked at rising temperatures as well as wildfires and pollution on babies and foetuses, the professors and co-editors said: “The evidence is clear: climate hazards, particularly heat and air pollution, do adversely impact a wide range of reproductive, perinatal and paediatric health outcomes.
"Failure to urgently address the reproductive, perinatal and paediatric health impacts of climate change will perpetuate and worsen reproductive injustices.
“The expected pace of continued climate change and resulting impacts on our physical and mental health and wellbeing calls for decisive and immediate action on adaptation.”

The professors added that the evidence also found that mothers from more marginalised populations are at much higher risk of being exposed to climate hazards, and were also less resilient to the effects of these hazards due to systematic and structural oppression.

They continued: “Our climate has already changed profoundly due to human activity and these changes are broadly harmful to our health, with some communities and individuals affected much more than others. Reproductive justice is ‘…the human right to maintain personal bodily autonomy, have children, not have children, and parent the children we have in safe and sustainable communities’.

Failure to urgently address the reproductive, perinatal and paediatric health impacts of climate change will perpetuate and worsen reproductive injustices, wherein the most marginalised populations will be deprived of their ability to procreate and safely parent their children.”

Temperature records continued to be broken in 2021, with US scientists confirming the Earth experienced its sixth hottest year on record.

For 25 countries, 2021 was their warmest year on record with record-high temperatures in parts of northern Africa, south Asia and areas of South America. Australian climate scientists say the findings reinforce the longer-term trend of rising temperatures around the world.

(AU ABC) Is Climate Change Behind Record-Breaking Temperatures In The Pilbara?

ABC Pilbara - Laura Birch

The Bureau of Meteorology says there has been an increase in the frequency of extreme heat events in Australia due in part to climate change.

Key Points
  • Three towns in the Pilbara surpassed 50C this week
  • The Bureau of Meteorology says a build-up of hot air led to the extreme weather event, but climate change could also be a factor
  • Climate expert Jatin Kala says it is alarming how many record weather events are occurring
This week Onslow, 1,377 kilometres north of Perth, reached 50.7 degrees Celsius.

It equalled the hottest temperature ever recorded in Australia and the Southern Hemisphere.

Also in the Pilbara region, the mercury soared to 50.5C in Roebourne and Mardie.

Previously, temperatures had only exceeded 50C three times in Australia's history.

BOM duty forecaster Jessica Lingard said while it was hard to pin climate change as the sole reason for temperatures spiking in the Pilbara this week, it could be a factor.

"If we look back at the 2019 climate report which was published by the bureau and the CSIRO, that showed there has been an increase in the frequency of extreme heat events and record high temperatures," Ms Lingard said.

She said the Pilbara could experience these high temperatures more often.

What caused the hot weather in Onslow? Ms Lingard said it was unexpected a town on the coast of Australia would reach 50.7C.

"We normally expect to see our hotter temperatures further inland because they don't have the coastal, cooling effects of having an ocean nearby," she said.

"What happened was we had a very hot air mass over WA and then we had really strong offshore winds.
"Winds blowing from the centre of Australia out over the ocean, and they blocked the usual arrival of [the] cooler sea breeze."
This allowed the temperatures to continue to increase.

"Looking forward in the next year or two, or even in the next decade we may start to see these hotter temperatures becoming more frequent as I say due to the implications of climate change," Ms Lingard said.

Is climate change a factor? Murdoch University senior lecturer in atmospheric science Jatin Kala said he was concerned about the frequency of these record-breaking temperatures.

"If you look at the past decade, I think about seven of the hottest years on record have happened in the last decade," he said.

"Out in the Pilbara it does get very hot, that's not unusual.
"What is really concerning is the rate at which these records are being broken."
Dr Kala said it showed the global climate was warming rapidly. Curtin University climate change expert Ashraf Dewan said it was difficult to say whether the record-breaking temperatures in the Pilbara were the result of climate change.

"That might be an indirect effect of climate change because that region is experiencing low rainfall," he said.

But Dr Dewan said extreme and random weather patterns would become more common in the future.
'If we can't control the emissions that may actually lead to new temperature records every year, we don't know," he said.
Dr Kala said there needed to be concerted action globally.

"As we increase the concentration of greenhouse gases in the Earth's atmosphere we generate more warming and as we warm the mean global temperature we're going to get more regional extremes," he said.

"We need politicians to listen to the science and we really need to curb down our emissions of greenhouse gases to net zero as soon as we can."

The WA Minister for Climate Change has been contacted for comment.
