Un aumento del 50% en el nivel de dióxido de carbono (CO 2 ) en la atmósfera podría reducir las precipitaciones en la Amazonía tanto o incluso más que la sustitución de todo el bosque por pastos.
El aumento de CO 2 reduciría la cantidad de vapor de agua emitido por el bosque, lo que provocaría una caída anual del 12% en el volumen de lluvia, mientras que la deforestación total reduciría las lluvias en un 9%.

One was: what would happen over the next 100 years if the ratio of carbon dioxide in the atmosphere reached 588 parts per million? For most of human history, this ratio hovered around 288ppm. Worldwide, since the global exploitation of fossil fuels began 200 years ago, this ratio has already soared beyond 400 ppm. And under various climate scenarios, the 588 ppm figure could happen by 2050, or 2080.
The second question was: what would happen over a century if the entire forest - it spreads [...]

(Climate News Network, 7 Jul 2021) More carbon dioxide could parch the rainforest as effectively as the woodman’s axe or farmer’s torch. Both are on the cards.
Brazilian scientists have identified a new way to take the rain out of the rainforest. All the world has to do is to make sure more carbon dioxide reaches the trees − half as much again as today.
The effect will be stark: it will be roughly the same as if Brazil’s business leaders, politicians and farmers [...]

A 50% rise in the level of carbon dioxide (CO2) in the atmosphere could reduce rainfall in the Amazon as much as or even more than substitution of the entire forest by pasture.
The rise in CO2 would reduce the amount of water vapor emitted by the forest, leading to a 12% annual drop in the volume of rainfall, while total deforestation would reduce rainfall by 9%.
These estimates are presented in a study published in Biogeosciences by scientists affiliated with the National [...]

Simulações em supercomputador mostram que o efeito pode ser similar ou até maior que o do desmatamento na região
Um aumento de 50% nos níveis de gás carbônico (CO2) na atmosfera pode ter um efeito na diminuição das chuvas na Amazônia similar ou até maior ao da substituição de 100% da mata por pastagens. A elevação do CO2 pode causar uma queda no vapor d'água emitido pela floresta [...]

The Amazon rainforest is on track to get a whole lot less rain over the coming century.
Even if deforestation is completely halted, research has found a global rise in carbon dioxide could still jeopardize the climate above the world's largest tropical rainforest.
According to new simulations, a 50 percent rise in global CO 2 emissions has the power to reduce rainfall in the Amazon by a drastic amount, possibly equivalent to what would occur if the entire forest was cut down and replaced [...]

Simulations show that the direct impact of rising levels of carbon dioxide over the Amazon rainforest would be a reduction in rainfall equivalent to or even greater than the impact of complete substitution of the forest by pasture
Newswise — A 50% rise in the level of carbon dioxide (CO 2) in the atmosphere could reduce rainfall in the Amazon as much as or even more than substitution of the entire forest by pasture. The rise in CO 2 would reduce the amount of water vapor emitted by the [...]
