"The United Nations warned on Tuesday that the two biggest water reservoirs in the United States have dwindled to “dangerously low levels” due to the impacts of climate change.
The situation has become so severe that these reservoirs, Lake Mead and Lake Powell, are on the verge of reaching “dead pool status” — the point at which water levels drop so low that downstream flow ceases, according to the U.N. Environment Program (UNEP).
“The conditions in the American West, which we’re seeing around the Colorado River basin, have been so dry for more than 20 years that we’re no longer speaking of a drought,” said Lis Mullin Bernhardt, an ecosystems expert at UNEP.
“We refer to it as ‘aridification’ — a new very dry normal,” Bernhardt added."
