The link between atmospheric CO2 levels and global warming is an axiom of current public policy, and is well supported by physicochemical experiments, by comparative planetary climatology and by geochemical modelling. Geological tests of this idea seek to compare proxies of past atmospheric CO2 with other proxies of palaeotemperature. For at least the past 300 Myr, there is a remarkably high temporal correlation between peaks of atmospheric CO2, revealed by study of stomatal indices of fossil…

Greenhouse crises of the past 300 million years

Proxies of past CO 2 and climate over the past 300 m.y. now reveal multiple global climate change events in unprecedented detail. Evidence for past CO 2 spikes comes from expanded and refined data on

The paleobotanical record of plants offers key insights into vegetation responses to past global change, including suitable analogs for Earth's climatic future, contrary to modeled predictions of the future.

Global and regional assessment of Neogene climate and palaeoceanography using dinoflagellate cysts

The Neogene Period (23.03–2.59 Ma) has been referred to as ‘the making of the Modern world’, which eventually, via a relatively consistent cooling trend, culminated in the present day climate



Atmospheric carbon dioxide concentrations over the past 60 million years

The boron-isotope ratios of ancient planktonic foraminifer shells are used to estimate the pH of surface-layer sea water throughout the past 60 million years, which can be used to reconstruct atmospheric CO2 concentrations.

Evidence for decoupling of atmospheric CO2 and global climate during the Phanerozoic eon

A reconstruction of tropical sea surface temperatures throughout the Phanerozoic eon (the past ∼550 Myr) from the database of oxygen isotopes in calcite and aragonite shells indicates large oscillations of tropicalSea surface temperatures in phase with the cold–warm cycles, thus favouring the idea of climate variability as a global phenomenon.

Paleobotanical evidence for near present-day levels of atmospheric Co2 during part of the tertiary.

This reconstruction indicates that CO(2) remained between 300 and 450 parts per million by volume for these intervals with the exception of a single high estimate near the Paleocene/Eocene boundary, and suggests that factors in addition to CO( 2) are required to explain these past intervals of global warmth.

A 300-million-year record of atmospheric carbon dioxide from fossil plant cuticles

A continuous 300-Myr record of stomatal abundance from Fossil leaves of four genera of plants that are closely related to the present-day Ginkgo tree is presented, supporting the role of water vapour, methane and CO2 in greenhouse climate warming over the past 300 Myr.

Dissociation of oceanic methane hydrate as a cause of the carbon isotope excursion at the end of the Paleocene

Isotopic records across the “Latest Paleocene Thermal Maximum“ (LPTM) indicate that bottom water temperature increased by more than 4°C during a brief time interval (<104 years) of the latest

Stability of atmospheric CO2 levels across the Triassic/Jurassic boundary

The relative stability of atmospheric CO2 across this boundary suggests that environmental degradation and extinctions during the Early Jurassic were not caused by volcanic outgassing of CO2, and other volcanic effects—such as the release of atmospheric aerosols or tectonically driven sea-level change—may have been responsible for this event.

Warm tropical sea surface temperatures in the Late Cretaceous and Eocene epochs

New data from exceptionally well preserved foraminifer shells extracted from impermeable clay-rich sediments indicate that for the intervals studied, tropical sea surface temperatures were at least 28–32 °C, more in line with the understanding of the geographical distributions of temperature-sensitive fossil organisms and the results of climate models with increased CO2 levels.

Massive dissociation of gas hydrate during a Jurassic oceanic anoxic event

Carbon-isotope analyses of fossil wood demonstrate that isotopically light carbon dominated all the upper oceanic, biospheric and atmospheric carbon reservoirs, and that this occurred despite the enhanced burial of organic carbon.

A 400 million year carbon isotope record of pedogenic carbonate: Implications for paleoatmospheric carbon dioxide

A 400 record of atmospheric carbon dioxide levels has been estimated by applying a CO{sub 2} paleobarometer to a database of 758 analyses of paleosol (fossil soil) carbonates. This database is a

Carbon Isotope Excursion in Atmospheric CO2 at the Cretaceous-Tertiary Boundary: Evidence from Terrestrial Sediments

Abstract A −1.5‰ to −2‰ carbon isotope excursion immediately above the clay layer that defines the Cretaceous-Tertiary (K/T) boundary has been reported in marine sediments world wide. This paper
