オーストラリアやカリフォルニアの親たちの間で、妊娠中の森林火災の煙への曝露が子供の健康問題の一因となっているのではないかとの懸念が高まっている。近年の大規模な火災はかつてないレベルの汚染をもたらし、火元から遠く離れた都市部の住民にも影響を及ぼした。
オーストラリアのキャンベラで看護師として働くアネケ・フレンチ氏は、2019年から2020年にかけて発生した「ブラックスサマー」の期間中、妊娠35週で常位胎盤早期剥離を経験した。娘のマーゴちゃんは早産で低出生体重児として生まれ、後に喘息や湿疹を発症した。フレンチ氏と担当産科医のスティーブン・ロブソン氏は、その夏の出産時に煙が病院の病室内にまで侵入していたことを指摘している。

Preliminary research from USC Norris Comprehensive Cancer Center, presented at the American Association for Cancer Research (AACR) annual meeting, found that non-smokers diagnosed with lung cancer before age 50 reported eating more fruits, vegetables and whole grains—and had higher overall Healthy Eating Index scores—than the U.S. population average. The researchers emphasized that the results do not prove diet causes lung cancer and said a possible explanation could involve environmental exposures such as pesticides, a hypothesis that requires direct testing.
A recent study in Science Advances has found that the number of days with conditions ideal for extreme wildfires—combining heat, drought, and wind—has nearly tripled globally in the past 45 years. This increase, driven largely by human-caused climate change, is most notable in the Americas and involves more frequent simultaneous risks across regions. The findings highlight challenges for firefighting resources and underscore the need for homeowner preparedness.

The American Lung Association's latest report reveals that 33.5 million US children, or 46 percent under age 18, live in areas failing at least one air pollution measure. An additional 7 million children reside in communities failing all three key metrics. The findings, based on 2022-2024 data, highlight worsening conditions amid environmental rollbacks.
A new study from UC Berkeley indicates that climate models may significantly underestimate carbon emissions from wildfires in boreal forests due to overlooked peat soil burning. Researchers analyzed 2018 wildfires in Sweden and found that smoldering underground fires release ancient carbon stored for centuries. This discrepancy highlights potential gaps in global emission estimates, especially in vast regions like Siberia and Canada.

Wildfires raging across Arctic and boreal regions are igniting ancient carbon in soils, releasing far more carbon dioxide than climate models have assumed. A new study of soil cores shows that some fires are burning organic matter up to 5,000 years old.
