All because of carbon dioxide, which causes the trees to have to love so that they can suck it better. Co2 It’s like a “fertilizer”, but how long will the trend continue?
The existence of more carbon dioxide (co2) In the atmosphere made the trees of the largest forest in the world to increase in size, as they know that They will have more work – they have to “suck” more2 DA Atmosfera.
“What we are observing is some space in the forest and, in this space, the average size of the trees is larger, which means that trees can store more carbon in this space than they could in the past,” says the researcher Esquivel-Muelbert to.
The investigators of this week in Nature found that, on average, The diameter of the trees increased by about 3.3% per decade.
“The structure of the Amazon rainforest is changing quite consistently throughout the basin,” says researcher Rebecca Banbury Morgan of the University of Bristol, United Kingdom. “We have more large trees and fewer small trees, soand the average size moved to higher valuesclose to the larger trees ”.
Researchers believe that Amazonian trees are responding to the increase in atmospheric levels of CO₂ growing more and accumulating more biomass. “The winners are the large trees, which compete better for light and water,” says Esquivel-Muelbert.
“The most important result is that CO₂ has acted as fertilizerincreasing trees growth, and in many ways this is encouraging, because wood is a global carbon sink, ”says Peter Etchells of Durham University, UK.“ However, it will continue to be as the climate continues to change, potentially changing the balance between growth, nutrients, temperature and coa? ”.
