On Sunday, July 21, the world had its hottest day on record. Just 24 hours later, that record broke again making last Monday very likely the hottest day in thousands of years.
It may seem improbable for scientists to gauge the world's hottest day given that they don't have temperature monitors in every corner of the world and less than a century of relatively widespread observations. But they've developed a technique that's increasingly useful as the planet heats up.
This month's shocking heat findings, announced by the EU's Copernicus Climate Change Service, are based on "reanalysis," a technique that mixes temperature data and models to provide a global view of the climate. The center creates a nearly real-time picture of the Earth's climate, including temperature, wind and precipitation, for (roughly) every 30-square-kilometer chunk of the planet's surface.
