So Much For The “Hottest Ever" People
We are in yet another InterGlacial Period.

Question and challenge those people who glibly talk about today’s temperature relative to ‘historical or climate’ data and particularly 'records'.
The world’s temperature data-record starts circa 1880 (a blink of an eye in climate terms) when mercury-thermometers came into common use, however even then, there was very limited ‘world-coverage’ and don’t forget 70% is covered by water from polar ice to tropical heat.

Prior to 1880 people were ‘guesstimating’ historic temperatures from the size, color and spacing of tree rings, that are themselves another wink of the glacial-history, most of which have turned into oil or coal.

World’s Temperature Data Started 1880
Why does the temperature record shown on your "Vital Signs" page begin at 1880? – Climate Change: Vital Signs of the Planet (nasa.gov)
Three of the world’s most complete temperature tracking records, maintained by NASA’s Goddard Institute for Space Studies, the National Oceanic and Atmospheric Administration’s National Climactic Data Center and the UK Meteorological Office’s Hadley Centre, begin in 1880. The oldest continuous temperature record is the Central England Temperature Data Series, which began in 1659, and the Hadley Centre has some measurements beginning in 1850, but there are too few data before 1880 for scientists to estimate average temperatures for the entire planet. To compensate for the lack of direct temperature data, scientists rely on reconstructed data from proxy records, such as tree rings, pollen counts, and ice cores. Because these proxy records differ fundamentally from direct measurements, scientists typically do not include them on the same charts as the "instrumental record."
