Description

Português: Elaborado pelos pesquisadores Newton Silva de Lima e Alan dos Santos Ferreira, o relatório analisa o severo El Niño de 2026 na Amazônia Central, destacando o forte estresse hídrico em Manaus — com sensação térmica de 42 °C e precipitação mensal caindo para 3,6 mm em agosto — em consonância com a tendência contínua de aquecimento regional de +0,25 °C por década (1940–2026). A ausência de lavagem atmosférica associada a inversões térmicas noturnas aprisiona poluentes como PM2.5, SO2, NOx e CO, enquanto simulações HYSPLIT demonstram a dispersão de plumas de queimadas e emissões da UTE-Mauá sobre áreas urbanas. Adicionalmente, a combustão em lixões na calha do Rio Madeira libera Microplásticos Atmosféricos (AMPs) e Poluentes Orgânicos Persistentes (POPs) que se depositam nos ecossistemas aquáticos provocando bioacumulação, além de agravar o risco aviário para a aviação regional e desencadear crises de saúde cardiorrespiratória em grupos vulneráveis.

English: Authored by researchers Newton Silva de Lima and Alan dos Santos Ferreira, the report analyzes the severe 2026 El Niño in the Central Amazon, highlighting extreme water stress in Manaus — where thermal sensation reached 42 °C and monthly rainfall dropped to 3.6 mm in August — consistent with a long-term regional warming trend of +0.25 °C per decade (1940–2026). The lack of wet deposition combined with nocturnal thermal inversions traps harmful pollutants like PM2.5, SO2, NOx, and CO, while HYSPLIT simulations demonstrate the transport of smoke plumes from wildfires and UTE-Mauá industrial emissions directly over residential areas. Furthermore, open burning at dumpsites along the Madeira River basin releases Atmospheric Microplastics (AMPs) and Persistent Organic Pollutants (POPs) that deposit into aquatic systems causing bioaccumulation, alongside escalating bird-strike risks for regional aviation and triggering cardiorespiratory health crises among vulnerable populations.
