Las Vegas saves 203B gallons removing lawns, but land temps spike 20°C

Las Vegas has been removing grass lawns as part of a water conservation initiative, successfully saving 203 billion gallons of water. However, the strategy has produced an unintended consequence: local summer land-surface temperatures have risen by approximately 20 degrees Celsius. The sharp increase in heat has raised environmental concerns among officials and researchers. In response, water agencies are now encouraging residents to adopt water-efficient landscaping and plant shade trees. New regulations have also been introduced to prohibit the installation of grass in residential yards going forward.
