This study provides a comprehensive and quantitative estimate of how global temperatures
have changed during the last 540 million years. It combines paleotemperature …

The climate of the Triassic period was characterized by a non-zonal pattern, dictated by a
strong global monsoon system with effects that are most evident in the Tethys realm. This …

High-resolution oxygen isotope records document the timing and magnitude of global
warming across the Permian-Triassic (P-Tr) boundary. Oxygen isotope ratios measured on …

The first book to review all the evidence concerning both the dinosaur extinctions and all the
other major extinctions-of plant, animal, terrestrial, and marine life-in the history of life. All the …

The repeated association during the late Neoproterozoic Era of large carbon-isotopic
excursions, continental glaciation, and stratigraphically anomalous carbonate precipitation …

The Mesozoic, perhaps representing the longest period of warmth during Phanerozoic Earth
history, contains in general sparse and frequently equivocal evidence for polar ice. Although …

General circulation models (GCMs) use the laws of physics and an understanding of past
geography to simulate climatic responses. They are objective in character. However, they …

Early Triassic coals are unknown, and Middle Triassic coals are rare and thin. The Early
Triassic coal gap began with extinction of peat-forming plants at the end of the Permian (ca …

That the Earth's climate has cooled over the last 100 million years has been recognized
since the early nineteenth century—the transition from the 'hot-house'world of the …

Permian waning of the low-latitude Alleghenian/Variscan/Hercynian orogenesis led to a
long collisional orogeny gap that cut down the availability of chemically weatherable fresh …
