New perspectives on deep carbon cycling
W Sun - Science China Earth Sciences, 2024 - Springer
The proto-atmosphere serves as a crucial starting point for the carbon cycle. Estimations
based on atmospheric data from Mars and Venus suggest that Earth's proto-atmosphere …

Continuous sterane and phytane δ13C record reveals a substantial pCO2 decline since the mid-Miocene
Constraining the relationship between temperature and atmospheric concentrations of
carbon dioxide (p CO2) is essential to model near-future climate. Here, we reconstruct p …

Long- and short-term coupling of sea surface temperature and atmospheric CO2 during the late Paleocene and early Eocene
The late Paleocene and early Eocene (LPEE) are characterized by long-term (million years,
Myr) global warming and by transient, abrupt (kiloyears, kyr) warming events, termed …

Improving hydrological modeling to close the gap between elevated CO2 concentration and crop response: implications for water resources
Rising atmospheric carbon dioxide concentrations ([CO 2]) affect crop growth and the
associated hydrological cycle through physiological forcing, which is mainly regulated by …

Eocene maar sediments record warming of up to 3.5° C during a hyperthermal event 47.2 million years ago
Eocene hyperthermal events reflect profound perturbations of the global carbon cycle. Most
of our knowledge about their onset, timing, and rates originates from marine records. Hence …

[PDF][PDF] Global Mean and Relative Sea-Level Changes Over the Past 66 Myr: Implications for Early Eocene Ice Sheets
We estimate ice-volume driven (barystatic; BSL) sea-level changes for the Cenozoic using
new Mg/Ca data from 58 to 48 Ma and a revised analysis of Mg/Ca trends over the past 66 …

Changes in pCO2 and climate paced by grand orbital cycles in the late Cenozoic
As one of the most important greenhouse gases, CO 2 is considered a major controlling
factor of Earth's climate over geological timescales. However, the origins of quasi-periodic …
