Sicilianews24.it: Anelli degli alberi: rivelazioni sul cambiamento climatico in Amazzonia e il suo impatto.

I cambiamenti nel clima dell’Amazzonia
Negli ultimi anni, l’Amazzonia ha affrontato alcune delle peggiori crisi idriche della sua storia. Uno studio condotto da scienziati del Regno Unito e del Brasile ha analizzato gli anelli di crescita degli alberi per comprendere appieno le dinamiche climatiche della regione. Il 2024 ha visto il verificarsi di una delle peggiori siccità mai registrate, con livelli d’acqua nel porto di Manaus, la città principale lungo il fiume Amazon, scesi a 12,68 metri, il valore più basso dal 1902. Questi eventi estremi richiedono una riflessione seria sulle cause alla base di queste modifiche.
Le osservazioni indicano che negli ultimi quattro decenni c’è stata un’intensificazione dei fenomeni estremi: le piogge si sono amplificate durante la stagione delle piogge e si sono ridotte durante quella secca. Questo fenomeno è attribuibile a vari fattori, tra cui la deforestazione e il cambiamento climatico, con effetti diretti sull’ecosistema forestale e sul ciclo del carbonio. Gli scienziati stanno individuando la complessità di questi cambiamenti, chiara evidenza che qualcosa di significativo sta avvenendo.

Tree rings: revelations about climate change in the Amazon and its impact.

Changes in the Climate of the Amazon

In recent years, the Amazon has faced some of the worst droughts in its history. A study conducted by scientists from the United Kingdom and Brazil analyzed tree growth rings to fully understand the climatic dynamics of the region. 2024 saw the occurrence of one of the worst droughts ever recorded, with water levels in the port of Manaus, the main city along the Amazon River, dropping to 12.68 meters, the lowest level since 1902. These extreme events require serious consideration of the causes behind these changes.

Observations indicate that over the past four decades there has been an intensification of extreme phenomena: rainfall has increased during the rainy season and decreased during the dry season. This phenomenon is attributable to various factors, including deforestation and climate change, with direct effects on the forest ecosystem and the carbon cycle. Scientists are identifying the complexity of these changes, clear evidence that something significant is happening.
