NIPTON, CA - AUGUST 26: In an aerial view, a boiler tower is surrounded by mirrors at the Ivanpah Solar Electric Generating System in the Mojave Desert on August 26, 2022 near Nipton, California. As drought, wildfires and monsoonal desert flash floods worsen in California, the development of solar energy farms has become prioritized as a means to lessen some of the worst impacts of human-caused climate change. Ironically, this "green energy" is harming the environment as it sprawls across pristine desert land, which stores carbon in the ground. California deserts account for nearly 10 percent of the states carbon sequestration. The Ivanpah Solar Electric Generating System is one of the biggest but has been challenged by reports that thousands of birds have been incinerated mid-flight by intense heat in the concentrated sun rays that are reflected to giant boiler towers.

Summer Ship Tracks in the Pacific August 26, 2018 In August 2018, long, narrow clouds stood out against the backdrop of marine clouds blanketing much of the North Pacific Ocean. Known as ship tracks, the distinctive clouds form when water vapor condenses around the tiny particles emitted by ships in their exhaust. Ship tracks typically form in areas where thin, low-lying stratus and cumulus clouds are present. ... The Moderate Resolution Imaging Spectroradiometer (MODIS) on Aqua captured this natural-color image of several ship tracks extending northward on August 26, 2018. The clouds were located about 1,000 kilometers (600 miles) west of the California-Oregon border. Similar environmental conditions also triggered the formation of ship tracks in this part of the Pacific on August 27 and 28.

CHENNAI, INDIA DECEMBER 22: The black polymetallic sea nodules, the nickel, manganese and cobalt rich mineral deposits, these balls form naturally deep under the sea. Indian deep ocean exploration vehicle under development as part of Samudrayaan (Ocean Craft) program a part of deep ocean mission, seen on December 22, 2022 at the National Institute Of Ocean Technology Institute, Chennai, India. The metallic sphere is called Matysa 6000 and it is estimated it can travel to six kilometres below the sea surface. The endeavour is to explore the Indian Ocean to tap and mine the polymetallic sea nodules, the nickel, manganese and cobalt rich mineral deposits and to explore the biodiversity. Indian scientists are working to complete it as soon as possible. The pressurised crew module can accommodate three crew. (Photo by Pallava Bagla/Corbis via Getty Images)

OXNARD, CALIFORNIA - MARCH 27: A stranded California sea lion suffering from suspected domoic acid poisoning cranes its head on the beach, before being rescued by CIMWI (Channel Islands Marine & Wildlife Institute) volunteers, on March 27, 2025 in Oxnard, California. Domoic acid poisoning sometimes causes sea lions to crane their heads in an upward “stargazing” motion. Hundreds of sea lions and over 100 dolphins, along with birds, are suspected to have been poisoned from eating fish which ingested toxic algae along the Southern California coastline in recent weeks. This is the fourth consecutive year of a domoic acid harmful algal bloom event along the coast of Southern California. (Photo by Mario Tama/Getty Images)
