Paleoclimatology (British spelling, palaeoclimatology) is the scientific study of climates predating the invention of meteorological instruments, when no direct measurement data were available. [1] As instrumental records only span a tiny part of Earth's history , the reconstruction of ancient climate is important to understand natural ...
Reconstructions of global temperature of the past 2000 years, using composite of different proxy methods. In the study of past climates ("paleoclimatology"), climate proxies are preserved physical characteristics of the past that stand in for direct meteorological measurements [1] and enable scientists to reconstruct the climatic conditions over a longer fraction of the Earth's history.
The most successful applications of isotope paleoclimatology have been the study of foraminifera from deep-sea sediments. For instance, Shackleton and Kennett (1975) have established the Cenozoic paleotemperature history based on analyzing oxygen isotope composition of both planktonic and benthic foraminifera in the Antarctic region.

Pluto's reign. For decades, students learned the phrase "My Very Educated Mother Just Served Us Nine Pizzas" to remember the order of the planets in the solar system: Mercury, Venus, Earth, Mars ...
Reconstruction of the past 5 million years of climate history, based on oxygen isotope fractionation in deep sea sediment cores (serving as a proxy for the total global mass of glacial ice sheets), fitted to a model of orbital forcing (Lisiecki and Raymo 2005) [2] and to the temperature scale derived from Vostok ice cores following Petit et al. (1999).
Tau with abnormal phosphorylation is referred to as hyperphosphorylated, and it clumps together to form NFTs, which gradually build up inside cells, causing their death.
