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.
Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
Samples carry Proxies. Thicker bands = warmer, wetter weather Visual and Microscope: ca 13,000 yrs BP Dendroclimatology: Biological Annual bands of seasonally differing woody growth tissue in trees Thicker bands = warmer and/or wetter weather, although some studies found thinner trunks for higher temperatures [1] Visual and Microscope: ca ...

Goals of paleogeosciences include understanding and recreating the Earth System over time for use in understanding the future of the Earth. It uses tangible data and proxy data. See Resources section for links to catalogs of hundreds of resources for data, software, and sample collections pertaining to many realms of paleogeoscience. [3] [4] [5]
Throughout Earth's climate history (Paleoclimate) its climate has fluctuated between two primary states: greenhouse and icehouse Earth. [1] Both climate states last for millions of years and should not be confused with the much smaller glacial and interglacial periods, which occur as alternating phases within an icehouse period (known as an ice age) and tend to last less than one million years ...
