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
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.

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.

mass nounThe 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.
