Dendrocronologia e Assinaturas Climatológicas Globais -Análise de Eventos Cósmicos e Geofísicos em Anéis de Crescimento de Scleronema micranthum em Itacoatiara - AM. A presente pesquisa investiga a integração entre a dinâmica dendrocronológica de espécies tropicais e as assinaturas climatológicas e geofísicas globais. O objetivo central é demonstrar como anéis de crescimento de árvores na Amazônia Central atuam como biossensores de eventos cósmicos e variações no campo magnético terrestre. A metodologia consistiu na análise dendrométrica de discos de madeira de Scleronema micranthum, provenientes de uma área de manejo florestal em Itacoatiara, AM. Os dados revelaram um Incremento Médio Anual (IMA) de 0,95 cm, permitindo a construção de uma série temporal correlacionada aos ciclos solares 22 a 25. Os resultados indicam uma correspondência entre os picos de crescimento radial e eventos de Partículas Energéticas Solares (SEP) e Ground-Level Enhancement (GLE), corroborando estudos globais sobre eventos radioisotópicos (Eventos Miyake) e eventos Forbush. Conclui-se que a dendrocronologia equatorial é uma ferramenta essencial para a calibração de modelos paleoclimáticos e para a avaliação de riscos à infraestrutura tecnológica contemporânea, fornecendo dados críticos sobre a vulnerabilidade da biosfera frente a anomalias geomagnéticas.

Abstract Dendrochronology and Global Climatological Signatures - Analysis of Cosmic and Geophysical Events in Growth Rings of Scleronema micranthum in Itacoatiara - AM This research investigates the integration between the dendrochronological dynamics of tropical species and global climatological and geophysical signatures. The main objective is to demonstrate how tree rings in the Central Amazon act as biosensors for cosmic events and variations in the Earth's magnetic field. The methodology involved the dendrometric analysis of Scleronema micranthum wood discs from a forest management area in Itacoatiara, AM, Brazil. The data revealed a Mean Annual Increment (MAI) of 0.95 cm, allowing the construction of a time series correlated with solar cycles 22 to 25. The results indicate a correspondence between radial growth peaks and Solar Energetic Particle (SEP) and Ground-Level Enhancement (GLE) events, supporting global studies on radioisotopic events (Miyake Events). It is concluded that equatorial dendrochronology is an essential tool for calibrating paleoclimatic models and assessing risks to contemporary technological infrastructure, providing critical data on biosphere vulnerability to geomagnetic anomalies.
