Hormuz Blockade Halts Iranian Oil, Sea Temps Hit 20.97°C Signaling El Niño, Emperor Penguins Endangered

U.S. blockade of Strait of Hormuz halted all Iranian oil loadings as of April 15, 2026, with no vessels passing and tanker Rich Starry making three U-turns in 24 hours per analyst Subasic. Global sea surface temperatures averaged 20.97°C in March 2026, second-highest on record per Copernicus Climate Change Service, indicating likely El Niño transition. IUCN downgraded emperor penguins to Endangered with 50% population halving projected by 2080s due to sea-ice loss.
