Earth had one of its warmest years on record last year, continuing an alarmingly steady trend where each of the past four decades has ranked hotter than the one before it, government science agencies announced Thursday.
The global average surface temperature in 2021 was the sixth-highest in recorded history, coming in 1.51 degrees Fahrenheit warmer than the 20th century average, according to officials at NASA and the National Oceanic and Atmospheric Administration.
The newly announced figures are based on independent analyses done yearly by both agencies. The report's findings are an important indicator of the planet's long-term health and provide a gauge of how Earth's climate has changed from year to year since record-keeping began in 1880.
NASA said global average surface temperatures last year tied with 2018 as the sixth-warmest on record, but noted that the past eight years have collectively been the warmest years in recorded history.

Yeah, who cares? We aren't doing anything to affect the planet so there is no reason for us to care. This is just what happens with the Earth. /s

...""Science leaves no room for doubt: Climate change is the existential threat of our time," NASA Administrator Bill Nelson said in a statement.
Ocean heat content, which is a measure of the amount of heat stored in the upper levels of the ocean, hit a record high in 2021, according to the NOAA report. Russell Vose, chief of climate monitoring at NOAA’s National Centers for Environmental Information, said the warmth of the world’s oceans last year was “the highest since records began six decades ago.”
“The point is, the oceans are storing a heck of a lot of heat,” he added.
Though oceans naturally absorb and store heat, the pace of ocean warming is a concern because increasing temperatures in these bodies of water can contribute to ocean acidification, sea-level rise and extreme weather.
NOAA said 2021 marked the 45th consecutive year since 1977 in which global temperatures ranked higher than the 20th century average, providing yet another indication of the effect of climate change on the planet.
"There's a lot of collected information that paints this coherent picture of a warming world," Vose said Thursday in a news briefing. "It's pretty clear that it's getting warmer."...
