Definition and origins of the term “greenhouse” The term “greenhouse” is defined, as follows, from a climatological standpoint in the online ‘Oxford English Dictionary’ (OED), based on the textbook by Trewartha (1937, p. 25): “The phenomenon whereby...

Journal Article

Stable isotope ratios of whole rock carbonates and faunas from three low latitude Upper Ordovician sections demonstrate a coherent pattern of shifting subtropical and tropical water masses and associated climate belts. We suggest that tropical water... Read More about Response of the Inter-tropical Convergence Zone to Southern Hemisphere cooling during Upper Ordovician glaciation.

This study presents isotopic data (δ¹³C and δ¹⁵N from bone collagen) for 104 samples representing 29 vertebrate taxa from late pre-contact through to contact era (ca. 2000 – 100 BP) Haida Gwaii (British Columbia, Canada) from a wide variety of mostly...

Mid-Miocene paleoproductivity in the Atlantic Ocean and implications for the global carbon cycle (2009)
Journal Article

A prominent, middle Miocene (17.5–13.5 Ma) carbon isotope excursion ubiquitously recorded in carbonate sediments has been attributed to enhanced marine productivity and sequestration of 13C depleted organic carbon in marine sediments or enhanced carb...

No evidence for thermogenic methane release in coal from the Karoo-Ferrar large igneous province (2009)
Journal Article

The Early Jurassic Toarcian oceanic anoxic event (T-OAE) and concurrent negative carbon-isotope (δ13C) excursion have recently been attributed to either the release of methane (CH4) clathrates or thermogenic CH4 gas associated with the Karoo-Ferrar l...
