Core Insights - The Amazon rainforest is experiencing an increase in tree size, with an average growth of 3.2% every decade, correlating with rising atmospheric CO2 levels [1][3] Group 1: Research Findings - A study monitored 188 fixed plots in the Amazon rainforest over more than 30 years, during which atmospheric CO2 concentration increased by nearly 20% [3] - Both large and small trees in the Amazon are growing larger, which aligns with the "fertilization effect" caused by increased CO2 [3] - The research confirms that large trees significantly contribute to CO2 absorption, demonstrating the resilience of the Amazon rainforest in carbon sequestration despite climate change [3] Group 2: Environmental Impact - The study highlights the devastating effects of deforestation in the Amazon and emphasizes that large tropical trees, some hundreds of years old, cannot be replaced solely by planting new trees for equivalent carbon storage or biodiversity [3]
