Addressing the root causes of the climate crisis is essential to solving the worsening problem of water shortages in the Colorado River Basin, said a top environmental expert at the United Nations on Tuesday, emphasizing that the aridification of the region is part of a larger global trend.
The two largest reservoirs in the U.S., Lake Powell and Lake Mead, are part of the Colorado River watershed, and are both on the precipice of reaching dangerous "dead pool" status, according to the United Nations Environment Program (UNEP), with water levels dropping so low that water no longer flows downstream from the reservoirs.
"Overconsumption and the climate crisis could lead to water levels so low that downstream flows to hydroelectric plants would stop," tweeted UNEP, which would jeopardize access to electricity for millions of people in western states.
Maria Morgardo, UNEP's ecosystems officer for North America, noted that officials are expected to advise people across the region to cut water consumption, but stressed that the crisis is beyond the point of simply mitigating the effects.
"While regulating and managing water supply and demand are essential in both the short and long term, climate change is at the heart of this issue."
"While regulating and managing water supply and demand are essential in both the short and long term, climate change is at the heart of this issue," Morgardo said in a statement. "In the long term we need to address the root causes of climate change as well as water demands."
As Common Dreams reported in July, Lake Mead is currently at just 27% capacity. By the end of the year, scientists expect both human-made reservoirs to reach 25% capacity.
The Colorado River Basin provides water for more than 40 million people across California, Colorado, New Mexico, Utah, Wyoming, Arizona, and Nevada as well as northern Mexico. It also provides irrigation for agriculture in the region.
Climate experts say the human-caused climate crisis, driven by fossil fuel extraction, increases the risk of drought conditions like those seen in the West over the past two decades by pushing temperatures higher, reducing snowfall, and shifting the regions where rain storms fall.

The dry conditions in the West have become so prolonged, said UNEP ecosystems expert Lis Mullin Bernhardt, that "drought" is no longer the appropriate word to describe them.
"We refer to it as 'aridification'--a new very dry normal," Bernhardt said in a statement.
People across the American West are among about 2.3 billion people around the world who face water stress annually, as up to 40% of the world's land has become degraded--a condition that can be driven by drought.
"Drought and desertification are quickly becoming the new normal everywhere--from the U.S. to Europe and Africa," said UNEP.
In the U.S., the agency said, "drying American reservoirs underscore the need for urgent climate action."
