Oceans cover more than two-thirds of our blue planet. The waters move in a global
circulation system, driven by subtle density differences and transporting huge amounts of …

A prominent, abrupt climate event about 8200 years ago brought generally cold and dry
conditions to broad northern-hemisphere regions especially in wintertime, in response to a …

The evidence for the Little Ice Age, the most important fluctuation in global climate in
historical times, is most dramatically represented by the advance of mountain glaciers in the …

Abrupt changes in climate, termed Dansgaard–Oeschger and Heinrich events, have
punctuated the last glacial period (∼ 100–10 kyr ago) but not the Holocene (the past 10 kyr) …

Increasingly, environmental scientists, palaeoceanographers and geologists are collecting
quantitative records of environmental changes (time series) from sediments, ice cores, cave …

The extent of climate variability during the current interglacial period, the Holocene, is still
debated. Temperature records derived from central Greenland ice cores show one …

Multiple proxies for paleoclimatic and paleoenvironmental change within sedimentary
sequences have been developed; but understanding their relationships and their relative …

We analyzed lake-sediment cores from the Yucatan Peninsula, Mexico, to reconstruct the
climate history of the region over the past 2600 years. Time series analysis of sediment …

More than a decade ago, ice core records from Greenland revealed that the last glacial
period was characterized by abrupt climate changes that recurred on millennial time scales …

Geochemical and clay mineral parameters of a high accumulation marine sediment core
from the Chilean continental slope (41° S) provide a 7700 yr record of rainfall variability in …
