The Graph That Should Be Front-Page News

# Summary Sea-surface temperatures in the tropical Pacific Ocean's Niño 3.4 region have reached unprecedented levels in 2023, departing entirely from all previous records since 1982 based on direct satellite and buoy observations. This region, known as the "beating heart" of Earth's climate system, influences weather patterns globally, but current temperatures are occurring against a warmer baseline caused by human-induced climate change, which amplifies the intensity of natural climate variability and its impacts on extreme weather, droughts, and flooding worldwide. Despite the severity of this signal, the finding has received minimal media attention despite warranting front-page coverage.
