Na Jenụwarị 2025, otu n'ime Ọkụ na-egbu egbu kacha egbu n'akụkọ ihe mere eme US bibiri ọtụtụ mpaghara na mpaghara Los Angeles, gụnyere Pacific Palisades na Altadena.

Ọzọkwa, a nnyocha ekwuru na ọkụ ndị a jikọtara ya na ọnwụ karịrị 440 na mpaghara ahụ.
N'agbanyeghị nke a, ọnụọgụgụ ndị a anaghị ejide oke mmebi ahụ. Mmetụta ọdachi ahụ na ụbụrụ anyị na-amalite na-apụta
Ihe akaebe nke oge a dị egwu. Ikpughe anwụrụ ọkụ na ọgbaghara n'oge windo mmepe dị oke egwu nwere ike gbanwee nhazi na ọrụ ụbụrụ. Otu ọmụmụ ihe n'ala found that prenatal exposure to air pollution — the kind generated by wildfires, for example — was associated with measurable changes in fetal brain morphology, including reduced cortical folding and increased cerebrospinal fluid space. These changes were most pronounced when exposure occurred during mid-to-late pregnancy.
Ihe ọ pụtara dị omimi. Ụmụ nwanyị dị ime ndị na-ekuru anwụrụ ọkụ dị ize ndụ n'ime ụbọchị January ndị ahụ na LA nwere ike ịmụ ụmụaka nwere mgbanwe dị nro ma dị ịrịba ama na mmepe ụbụrụ.

Mmetụta na-agbatị karịa afọ ime. Nnyocha a na-eme ugbu a has illustrated that exposure to fine particulate matter from wildfires is a greater risk factor for dementia than that from other sources (like car exhaust). Similarly, a study on California’s 2018 Camp Fire kpughere na ikpughe na trauma sitere na ọdachi ihu igwe na-agbanwe n'ụzọ bụ isi na-agbanwe ikike ime mkpebi.

Understanding these long-term health impacts is particularly complex because the neurological effects in question aren’t limited to smoke exposure. The psychological trauma of losing homes, communities, and loved ones creates what researchers call “climate trauma”: a distinct form of mental and cognitive health impairment that affects brain function in measurable ways. Behavioural and psychological effects have been documented in recent iche echiche ahụ ike nyocha nke LA na Maui ndị lanarịrị ọkụ ọhịa. Nyocha ụbụrụ nke ndị lanarịrị ọdachi show hyperactivity na mpaghara jikọtara ya na nchekasị na nchekasị, tinyere ọrụ na-adịghị mma na mpaghara ndị na-ahụ maka ime mkpebi na nhazi mmetụta uche.

And we need policies that account for the full neurological cost of climate change when making decisions about everything from urban planning to health care resource allocation.
