The Turonian (93.5 to 89.3 million years ago) was one of the warmest periods of the
Phanerozoic eon, with tropical sea surface temperatures over 35° C. High-amplitude sea …

Scientists have long been puzzled by the fact that mid-to-high latitude continental interiors
and the poles in the Eocene (55 to 34 Million years ago) were much warmer than today …

Oxygen isotopic measurements in three Late Quaternary deep-sea cores from the Gulf of
Mexico record a major anomaly between about 15,000 and 12,000 years ago superimposed …

Earth's climate during the last 4.6 billion years has changed repeatedly between cold
(icehouse) and warm (greenhouse) conditions. The hottest conditions (supergreenhouse) …

Evaluating the significance of Holocene submillennial δ18O variability in the Greenland ice
cores is crucial for understanding how natural climate oscillations may modulate future …

We propose that from∼ 3 to 1 million years ago, ice volume changes occurred in both the
Northern and Southern Hemispheres, each controlled by local summer insolation. Because …

Paleoclimatologists who study the tiny air bubbles trapped in ice cores are very lucky. They
can observe the composition of Earth's past atmosphere over hundreds of thousands of …

To understand the climate dynamics of the warm, equable greenhouse world of the Late
Cretaceous period, it is important to determine polar palaeotemperatures. The early …

Atmospheric carbon dioxide concentrations are believed to drive climate changes from
glacial to interglacial modes, although geological,, and astronomical,, mechanisms have …

The last glacial period was terminated by an abrupt warming event in the North Atlantic∼
15,000 years before the present, and warming events of similar age have been reported …
