The Hottest Eight Years On Record Were the Last Eight Years (theguardian.com) 111

An anonymous reader quotes a report from The Verge: The last eight years have been the eight hottest years on record, NASA and the National Oceanic Administration (NOAA) confirmed today. 2021 ranks as the sixth hottest year on record, the agencies said, as global average temperatures trend upward. Rankings aside, there were plenty of red flags throughout 2021 to show us how remarkable the year was for temperature extremes. "The fact is that we've now kind of moved into a new regime ... this is likely the warmest decade in many, many hundreds, maybe 1000s of years," says Gavin Schmidt, director of NASA's Goddard Institute for Space Studies. "There's enough change that it's having impacts locally."

In North America, those local impacts included epically bad summer heat, even for typically cool regions. In late June and early July, the Pacific Northwestern US and Western Canada struggled with record-smashing temperatures that buckled roads and melted power cables. In the desert further south, California's Death Valley reached a blazing 130 degrees Fahrenheit (54.4 degrees Celsius) in July, potentially breaking the world record for the hottest temperature ever recorded on the planet -- for the second year in a row. Across the Atlantic, Europe experienced sweltering heat, too. A reading of 119.8 degrees Fahrenheit (48.8 degrees Celsius) in Sicily might have broken the European record for maximum temperature. (The World Meteorological Organization is still working to vet those records.) All told, July 2021 was the hottest month humans have ever recorded, according to NOAA.

Heat trapped in the world's oceans also reached record levels in 2021, according to research published this week. Ocean heatwaves are likely twice as common now as they were in the early 1980s, and they can be devastating for marine life and coastal communities. They kill coral, take a toll on fishing and crabbing industries, and can even make droughts worse onshore. Temperatures might have been even hotter in 2021, were it not for a La Nina event. La Nina is a recurring climate phenomenon defined by cooler-than-average waters in the eastern equatorial Pacific, which has predictable effects on weather patterns worldwide.

      Few know this outside of the astronomy community, but the earth's climate is not stable. It goes through a 30,000 year cycle dictated by variations in where the earth's axis is pointed and other orbital variations. In fact, the last 10,000 years of relative stability are incredibly rare. That doesn't mean that we aren't contributing to changes within the climate, but it does mean that we shouldn't be expecting the perfect stability that most expect.

              Yes, the absorption spectrum of CO2 has been well understood for 100 years, its basic physics.

              What has not been understood and is still not known with certainty is the extent, if any, to which the forcing effect of increased CO2 is amplified by feedbacks.

              We know for sure that doubling CO2 ppm will have a forcing effect which, if everything else remains the same, will raise global temps by a bit over 1C.

        Well, cyclic variations can be stable. They are two different things. A repeatable cycle is still stable.

        Second, not sure where you get the 30,000 year period. You may be thinking of the 26,000 year period of the precession of the equinoxes, but the main orbital driver of climate is the Milankovitch variations, which trigger the advance and retreat of the glaciers. In the current epoch these run more like 100,000 years.
