Local names for the last glacial period include the Wisconsinan in North America, The Blytt–Sernander classification of climatic periods defined, initially, by plant remains in peat mosses, is now being explored currently by geologists working in different regions studying sea levels, peat bogs and ice core samples by a variety of methods, with a view toward further verifying and refining the Blytt–Sernander sequence.They find a general correspondence across Eurasia and North America, though the method was once thought to be of no interest.However, the warming was probably not uniform across the world.
The Holocene encompasses the growth and impacts of the human species worldwide, including all its written history, development of major civilizations, and overall significant transition toward urban living in the present.
Human impacts on modern-era Earth and its ecosystems may be considered of global significance for future evolution of living species, including approximately synchronous lithospheric evidence, or more recently atmospheric evidence of human impacts.
The sea level rise and temporary land depression allowed temporary marine incursions into areas that are now far from the sea.
Holocene marine fossils are known, for example, from Vermont and Michigan.
However, ice melt caused world sea levels to rise about 35 m (115 ft) in the early part of the Holocene.
