Definition of palaeoclimate in English:

palaeoclimate

(US paleoclimate)
noun ˈpeɪlɪəʊˌklʌɪmətˈpalɪəʊˌklʌɪmətˈpālēōklīmət
  • A climate prevalent at a particular time in the geological past.

    Example sentencesExamples
    • Through analysis of the paleoclimate record as well as a number of climate model simulations, we also suggest that it is very unlikely that the Atlantic Meridional Overturning will cease to be active in the near future.
    • The contradiction between the paleofauna and the uniformitarian paleoclimate is so great that one wonders why scientists do not question the uniformitarian paradigm.
    • The origin of the Brejos has been associated with humid paleoclimates established after the middle Tertiary, especially during interglacial phases of the Pleistocene.
    • The palaeoclimates during coal accumulation must have been very humid and very warm.
    • They not only provide evidence for ancient vegetation and ecosystems, but also contain signals of palaeoclimates that are independent of evidence from other associated sediments and fossils.

Derivatives

  • palaeoclimatic

  • adjective peɪlɪəʊˌklʌɪˈmatɪkpalɪəʊˌklʌɪˈmatɪk
    • Periods of loess deposition are found to correlate with glacial periods when loess profiles are compared to palaeoclimatic evidence from deep-sea cores.
      Example sentencesExamples
      • However, it is key to the interpretation of these palaeoclimatic records that one knows where they were when they were formed.
      • It may also prove possible in individual cases to quantitatively calibrate the trace elements for palaeoclimatic variables such as rainfall.
      • Comparable Pliocene palaeoclimatic fluctuations can also be seen in Southern Ocean silicoplankton records and marine isotopic records, and in seismic reconstructions of Antarctic glacial stratigraphy.
      • The basic idea mainly relies on paleoclimatic evidence that there would have been a new ice age by now under ‘normal’ circumstances, and since there isn't one, anthropogenic influences are presumably to blame.
  • palaeoclimatologist

  • noun ˌpalɪəʊˌklʌɪməˈtɒlədʒɪstˌpeɪlioʊˌklaɪməˈtɑlədʒəst
    • Consequently, the field is becoming much more interesting and dynamic, with collaborations bringing together, for example, paleontologists, ecologists, paleoclimatologists, and geologists.
      Example sentencesExamples
      • Much more work will have to be done by ocean modellers and palaeoclimatologists before the factors behind the variability are understood.
      • It is well-known amongst paleoclimatologists that there are no successful CO2 measurements from Greenland, the record shown is obviously from Antarctica.
  • palaeoclimatology

  • noun ˌpalɪəʊˌklʌɪməˈtɒlədʒiˈˌpeɪlioʊˌklaɪməˈtɑlədʒi
    mass noun
    • The branch of science that deals with climates prevalent at particular times in the geological past.

      Rather, many arbitrarily isolated ‘disciplines ‘- geology, micro-biology, paleoclimatology, atmospheric chemistry and geochemistry - are intrinsic to knowledge of life's history.’
      Example sentencesExamples
      • The technique allows estimation of growth rate of speleothems at any interval of interest, which is one of several possible uses in palaeoclimatology.
      • Transfer functions are frequently employed in Quaternary palaeoclimatology because they provide an important method of reconstructing past climatic conditions.
