"It seemed that both human influences and the sea surface temperature (SST) natural variability increased probabilities of the 2010 severe drought in the South Amazon region."

"Southeast Brazil experienced profound water shortages in 2014/15. Anthropogenic climate change is not found to be a major influence on the hazard, whereas increasing population and water consumption increased vulnerability."

"Northeast Brazil experienced profound water shortages in 2016 due to a five-year drought. Using multiple methods, we could not find sufficient evidence that anthropogenic climate change increased drought risk."

"We estimate that >90,000 people became temporarily homeless, and at least BRL 1.3bn ($240m) was lost in public and private sectors, of which 41% can be attributed to human-induced climate change."

"[H]uman-induced climate change is, at least in part, responsible for the increase in likelihood and intensity of heavy rainfall events as observed in May 2022."

"Rainfall events as rare as these, that occurred in a 1.2C cooler climate, would have been approximately a fifth less intense."

"[A]ll models exhibit systematic errors in precipitation magnitudes…We can therefore not quantify the role of climate change in the observed increase in likelihood and intensity."

"[We] assess changes in the likelihood and intensity for the 10-day and 4-day heavy rainfall over Rio Grande do Sul and find an increase in likelihood for both events of more than a factor of 2 and intensity increase of 6-9% due to the burning of fossil fuels."

"Hot, dry and windy conditions that drove devastating Pantanal wildfires 40% more intense due to climate change."
