The article discusses a graph showing sea-surface temperatures in the Niño 3.4 region of the equatorial Pacific, which has departed from the range of previous observations. The graph represents direct observations from satellites, ships, and ocean buoys, and its significance is being met with silence. The article explains that the warming of the tropical Pacific Ocean has consequences for the climate system, including amplifying natural variability and leading to more extreme weather events. The author argues that this graph should be front-page news and that its implications should be taken seriously.
