![]() ![]() This series of satellite images shows the ozone hole on the day of its maximum depth each year from 1979 through 2019. A study recently published in Science concluded dramatic steps must be taken to stabilize the river’s resources, including drastic consumption cuts. In the early 1980s, scientists began to realize that CFCs were creating a thin spota holein the ozone layer over Antarctica every spring. Water levels need to stay above 1,000 feet to continue operating hydropower turbines at the dam at optimal levels.Ī megadrought fueled by climate change and mismanagement of water resources has led to a sharp decline in Colorado River water levels over the past two decades. ![]() Bureau of Reclamation, water levels dropped to 1,041 feet. Water elevation at the end of July 2000 was less than 1,200 feet above sea level. Lake Mead July 3, 2022.Īt maximum capacity, water levels at the Hoover Dam would reach an elevation of 1,220 feet above sea level and would hold 9.3 trillion gallons of water. These are mineralized areas of the reservoir that were once underwater, referred to as a “bathtub ring.” Lake Mead July 6, 2000. The photos from 20 show significantly less water in a lighter shade of blue with light-colored fringes along the shorelines. The image from July 6, 2000, shows a full lake with a deep shade of blue. The November image shows Iceberg B-46 (center-right), comprising about 115 square miles (185 square kilometers), after it broke off of Antarctica’s Pine Island Glacier in late October 2018. NASA released side-by-side images of the reservoir taken from space in July of 2000, 20. Now satellite images recently released by NASA show the impact years of worsening drought has had on the reservoir that supplies water from the Colorado River to nearly 25 million people in Arizona, Nevada, California and parts of Mexico.Īs of July 18, 2022, Lake Mead was filled to just 27 percent of its capacity and water levels stand at their lowest since April 1937, when the reservoir was still being filled for the first time. Water levels at Lake Mead, the nation’s largest water reservoir which straddles the Arizona-Nevada border, are at a historic low as a megadrought plagues large parts of the American West. A megadrought fueled by climate change and mismanagement of water resources has led to a sharp decline in Colorado River water levels over the past two decades.The photos from 20 show significantly less water with a lighter shade of blue and light-colored fringes along the shorelines. The image from Jshows a full lake with a deep shade of blue.NASA released side-by-side images of the reservoir taken from space in July of 2000, 20.For more information, call Leslie Logan or Mar Perez at (607) 255-4308, or contact the Native Americas web site at. These events are part of a partnership between NASA and Akwe:kon Press that led to the publication of Native Americas' January double issue, titled "Global Warming, Climate Change and Native Lands." Sponsored by a $61,000 grant from NASA's office of Earth Science Enterprises, the double issue was the result of an unprecedented effort by NASA to seek Native American perspectives on the impact of climate change in the United States. Panelists will discuss a range of themes, including Native prophecy, Native responses and solutions to help mitigate climate change and maintain balance with the Earth, and NASA collaborations with Native communities. on the first floor of the Robert Purcell Community Center. It will provide an overview of global warming and climate change issues viewed from both a Native American and a NASA perspective. in the Townhouse Community Center on Jessup Road, across from the Robert Purcell Community Center on Cornell's North Campus. Mohawk, member of the Seneca Nation and a professor of American studies at the State University of New York at Buffalo Nancy Maynard, a program director with the NASA Goddard Space Flight Center Robert Gough, an attorney for the Rosebud Sioux Tribe Utility Commissionin South Dakota (S.D.) and Tim Johnson, from the Smithsonian's National Museum of the American Indian in Washington, D.C. Guest speakers will include Native American elder Oren Lyons, an Onondaga faithkeeper who served on the 1998 Native Peoples/Native Homelands Climate Change Workshop in Albuquerque, N.M. This event is free and open to the public. The Akwe:kon Press and Native Americas journal, part of the American Indian Program at Cornell University, will hold a "Global Warming/Climate Change" panel discussion on campus Feb.
