Los Patrones Climáticos

La lluvia que cae en el Amazonas tiene su origen en patrones climáticos que viajan del Este, en el océano Atlántico, hacia el Oeste, donde se trasladan a través de las tierras bajas del Amazonas y se aproximan a las montañas de los Andes. Al mismo tiempo, la transpiración diaria de los árboles amazónicos libera una gran cantidad de humedad al aire. A medida que esta humedad es empujada hacia los Andes, es apretada a través de valles estrechos, como el valle de Kosnipata, mostrado a continuación. Las nubes convergen y se condensan en forma de lluvia cuando golpean las montañas, que atrapan esta lluvia y la dirigen a los afluentes del río Amazonas. Casi el 20% de toda el agua dulce que viaja hacia los océanos del planeta, lo hace a través del río Amazonas.

Esta lluvia beneficia a las selvas tropicales amazónicas, que requieren de una cantidad significante de humedad durante la mayor parte del año. Los bosques utilizan esta humedad para la fotosíntesis, y luego, el vapor de agua es liberada en el aire. La deforestación del Amazonas inhibe este patrón, y seca los bosques de la parte occidental del continente. Científicos estiman que el 90% del Amazonas actual debe permanecer intacto para que este ciclo de humedad continúe y para que los bosques se mantengan sanos.

The Amazon Could Stop Breathing

The Amazon rainforest is home to hundreds of billions of trees essential for absorbing carbon dioxide. However, this process is reversed during years of drought, where the Amazon has produced carbon dioxide rather than consumed. A drought in 2005 turned the Amazon...
