Since 65 million years ago (Ma), Earth's climate has undergone a significant and complex
evolution, the finer details of which are now coming to light through investigations of deep …

Important aspects of the physics involved in the climate changes of late Quaternary time
elude us. The paleoclimatic record documents in detail that these changes were vast and in …

A 13-million-year continuous record of Oligocene climate from the equatorial Pacific reveals
a pronounced “heartbeat” in the global carbon cycle and periodicity of glaciations. This …

Millennial-scale (103 yr) variability is an important component in the spectrum of climate
change [Mitchell, 1976]. Although long documented from late-glacial and Holocene pollen …

Subpolar North Atlantic proxy records document millennial-scale climate variations 500,000
to 340,000 years ago. The cycles have an approximately constant pacing that is similar to …

Successful prediction of future global climate is critically dependent on understanding its
complex history, some of which is displayed in paleoclimate time series extracted from deep …

Understanding the natural variability of climate is important for predicting its near-term
evolution. Models of the oceans' thermohaline and wind-driven circulation show low …

An exceptional analogue for the study of the causes and consequences of global warming
occurs at the Palaeocene/Eocene Thermal Maximum, 55 million years ago. A rapid rise of …

The most recent ice age was characterized by rapid and hemispherically asynchronous
climate oscillations, whose origin remains unresolved. Variations in oceanic meridional heat …

The mid-Pleistocene transition (MPT) marked a fundamental change in glacial-interglacial
periodicity, when it increased from~ 41-thousand-year to 100-thousand-year cycles and …
