Sobering Lake Powell Satellite Views Show Impact of Severe Drought

A satellite tv for pc view of Lake Powell in March 2022 exhibits the reservoir’s low water degree. The yellow define exhibits the shoreline because it was in 2018.

The European House Company retains an eye fixed on happenings throughout the planet, together with the state of drought within the US. ESA on Monday launched a sequence of satellite tv for pc views of Lake Powell within the US Southwest that hint declining water ranges because the local weather crisis-fueled drought takes a toll on the reservoir.

Lake Powell is located in Arizona and Utah alongside the Colorado River. “After decades of drought, water levels in Lake Powell, the second largest human-made reservoir in the United States, have shrunk to its lowest level since it was created more than 50 years ago, threatening millions of people who rely on its water supply,” ESA stated in an announcement.

A GIF created from photos captured by the Copernicus Sentinel-2 satellite tv for pc exhibits the lake’s dramatic decline from 2018 to 2022. A yellow define seems on the finish for example how a lot the water has retreated in simply 4 years.

ESA stated the lake had dropped in March 2022 to the bottom it has been because it was first stuffed in 1980. NASA’s Earth Observatory additionally took a detailed have a look at Lake Powell in late 2021, tracing the falling water ranges to twenty years of drought, with particularly intense drought over the past two years.

Lake Powell’s decreasing ranges are one symptom of a bigger local weather disaster. An IPCC report in February painted a grim image for a planet “clobbered by climate change.” The IPCC is the United Nations’ chief local weather science group.  

Satellite photos of drought-stricken lakes spotlight the risk to water provides used for individuals, agriculture and hydroelectric energy. It is unhealthy now, however as ESA stated, “Climate change is expected to make droughts more severe in the future.”
