  • abbr. A thousand years


Sorry, no etymologies found.


  • According to IPCC Jansen et al., 2007, “it is possible to derive time series of atmospheric trace gases and aerosols for the period from about 650 kyr thousand years to the present from air trapped in polar ice and from the ice itself.”

  • The 8.2 kyr BP event simulated by a global atmosphere-sea-ice-ocean model.

    Late-Quaternary changes in arctic terrestrial ecosystems, climate, and ultraviolet radiation levels

  • Comparisons between anthropocene (1750-2005), last glacial termination (20 "" 11.7 kyr) and Pliocene (~3 Ma) CO2 levels, climate forcings, mean global temperatures and sea levels.


  • Thus the last termination (14.7 – 11.7 kyr) [kyr = thousand years] displays extreme temperature changes on the scale of several degrees C in a few years (Steffensen et al., 2008) to decade scale (Alley, 2003; Kobashi et al., 2008), testifying to an extreme sensitivity of the atmosphere and the possibility of climate impasse tipping points.

    The Price of the Earth

  • The role of North Atlantic climate change between 70 and 130 kyr ago.

    Arctic climate variability prior to 100 years BP

  • Given that current low orbital eccentricity will persist over the next tens of thousand years, the effects of precession are minimised, and extremely cold northern summer orbital configurations like that of the last glacial initiation at 116 ka will not take place for at least 30 kyr Box 6.1.

  • It is very unlikely that the Earth would naturally enter another ice age for at least 30 kyr.

  • Under a natural CO2 regime (i.e., with the global temperature-CO2 correlation continuing as in the Vostok and EPICA Dome C ice cores), the next glacial period would not be expected to start within the next 30 kyr (Loutre and Berger, 2000; Berger and Loutre, 2002; EPICA Community Members, 2004).

  • E. Slow-down of the North Atlantic thermohaline conveyor belt and down-welling water columns (NASA, 2004; Bryden et al., 2005), with attendant danger of its cessation analogous to conditions ~8. 2 kyr ago (Alley et al., 1997), considered in a Pentagon inquiry (Stipp, 2004);

    21st century climate tipping points

  • Climate change post-1750 is driven by total radiative forcing tracking toward c. 3 Watt/m2, near-half the forcing of 6. 5±1.5 Watt/m2 associated with the last glacial termination (c. 14.7 – 11.7 kyr).
