Amazon River carbon dioxide emissions nearly balance terrestrial uptake. New research in Brazil has found that rivers in the Amazon emit far more carbon dioxide (CO2) than previously estimated, suggesting that the Amazon Basin is closer to net carbon neutral. The results increase the most recent global estimates of CO2 emissions from rivers and lakes by almost 50 percent, with potentially huge implications for global climate policy. Ref. Source 8n.
Mother Nature is a lot stronger than we thought. It has more influence on the climate then we thought, which correspondingly means we have less influence. To change global climate change we have to understand it. It's clear to me we don't fully understand it yet.
