Over geological timescales, CO 2 levels are determined by the operation of the long term carbon cycle, and it is generally thought that changes in atmospheric CO 2 concentration …
Oxygen is essential for animal life, and while geochemical proxies have been instrumental in determining the broad evolutionary history of oxygen on Earth, much of our insight into …
A new oxygen isotope (δ 18 O) record derived from conodont apatite reveals variable long- term climate trends throughout the Triassic period. This record shows several major, first …
Because there remains a lack of knowledge about the spatially explicit distribution of chemical weathering rates at the global scale, a model that considers prominent first-order …

The tectonics, geography and climate of the Cretaceous world were very different from the modern world. At the start of the Cretaceous, the supercontinent of Pangaea had just begun …
Phosphate is an essential macronutrient for all organisms with a key role in setting levels of marine primary productivity. Despite its importance for marine biogeochemical cycles and its …
Long-term carbon and sulfur cycle models have helped shape our understanding of the Phanerozoic history of atmospheric CO~ 2~ and O~ 2~, but error analyses have been …

Earth's long‐term climate has been profoundly influenced by the episodic assembly and breakup of supercontinents at intervals of ca. 500 my This reflects the cycle's impact on …
Long-term carbon cycle models are critical for understanding the levels and underlying controls of atmospheric CO 2 over geological time-scales. We have refined the …
