Open accessAbstract
A recent increase in extreme flooding in Amazonia is linked to intensification of the atmospheric east-west Walker circulation.

Since the 1970s there has been an upward trend in the year-to-year variability of Amazon River discharge, following a period with no trend during 1904 through the 1960s.
“Since the 1970s there has been an upward trend in the year-to-year variability of Amazon River discharge, following a period with no trend during 1904 through the 1960’s (Satyamurty et al., 2013;Barichivich et al., 2018).”
From The tropical atlantic observing system (2019) · cites this paper as Barichivich et al., 2018
The Results section (page unavailable) reports that severe-flood frequency increased from around 1970, which supports a related increase in hydrological extremes. It does not establish an upward trend in year-to-year discharge variability or a trend-free period from 1904 through the 1960s. The Methods section says the study analyzed water levels rather than deriving discharge estimates. (LLM, conf=0.84)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
