| − | A vital system of Atlantic Ocean currents that influences weather across the world could collapse as soon as the late 2030s, scientists have suggested in a new study — a planetary-scale disaster that would transform weather and climate.
| + | Huge tributaries that feed the mighty Amazon River — the largest on the planet — have plunged to record-low levels, upending lives, stranding boats, and threatening endangered dolphins as drought grips Brazil. |
| | | | |
| − | Several studies in recent years have suggested the crucial system — the Atlantic Meridional Overturning Circulation, or AMOC — could be on course for collapse, weakened by warmer ocean temperatures and disrupted saltiness caused by human-induced climate change.
| + | The country is currently enduring its worst drought since records began in 1950, according to Cemaden, the country’s natural disaster monitoring center. It’s Brazil’s second straight year of extreme drought. Nearly 60% of the country is affected, with some cities, including the capital Brasília, enduring more than 140 consecutive days without rain. |

| − | But the new research, which is being peer-reviewed and hasn’t yet been published in a journal, uses a state-of-the-art model to estimate when it could collapse, suggesting a shutdown could happen between 2037 and 2064.
| + | In the heart of the Amazon rainforest, the impact on rivers is shocking and experts are sounding the alarm on what this means for the region, a biodiversity hot spot and crucial climate change buffer. |
| | | | |
| − | This research suggests it’s more likely than not to collapse by 2050.
| + | The Rio Negro, one of the Amazon River’s biggest tributaries, is at record lows for this time of year near the city of Manaus in Amazonas state. Its water levels are falling at around 7 inches a day, according to Brazil’s geological service. |

| − | “This is really worrying,” said René van Westen, a marine and atmospheric researcher at the University of Utrecht in the Netherlands and study co-author.
| + | The river’s characteristic jet-black waters usually course through its thick maze of channels, but satellite images now show it drastically shrunken with huge swaths of riverbed exposed. |

| − | “All the negative side effects of anthropogenic climate change, they will still continue to go on, like more heat waves, more droughts, more flooding,” he told CNN. “Then if you also have on top of that an AMOC collapse … the climate will become even more distorted.”
