In the United States, 40 million people in seven states depend on water provided by the Colorado River.After 20 years of drought, the situation is dire and the river is at risk of becoming a “deadpool,” a condition in which there is not enough water to pass through the dams.The states were supposed to come up with a deal to cut their usage by Tuesday. Now, the federal government may have to step in and make a difficult decision.Guest: Christopher Flavelle, a climate reporter for The New York Times.Background reading: The seven states that rely on the river for water are not expected to reach a deal on reductions. The federal government could impose cuts for the first time in the water supply for millions of Americans.For more information on today’s episode, visit nytimes.com/thedaily.

In the past half-century, 17 percent of the Amazon — an area larger than Texas — has been converted to croplands or cattle pasture. Less forest means less recycled rain, less vapor to cool the air, less of a canopy to shield against sunlight. Under drier, hotter conditions, even the lushest of Amazonian trees will shed leaves to save water, inhibiting photosynthesis — a feedback loop that is only exacerbated by global warming.According to the Brazilian Earth system scientist Carlos Nobre, if deforestation reaches 20 to 25 percent of the original area, “flying rivers” — rain clouds that recycle the forest’s own moisture five or six times — will weaken enough that a rainforest simply will not be able to survive in most of the Amazon Basin. Instead it will collapse into scrubby savanna, possibly in a matter of decades.Losing the Amazon, one of the most biodiverse ecosystems on Earth, would be catastrophic for the tens of thousands of species that make their home there. What scientists are most concerned about, though, is the potential for this regional, ecological tipping point to produce knock-on effects in the global climate.This story was recorded by Audm.
