Methane (CH4) is produced in many natural systems that are vulnerable to change under a
warming climate, yet current CH4 budgets, as well as future shifts in CH4 emissions, have …

Earth's climate is warming as a result of anthropogenic emissions of greenhouse gases,
particularly carbon dioxide (CO2) from fossil fuel combustion. Anthropogenic emissions of …

This chapter addresses the biogeochemical cycles of carbon dioxide (CO2), methane (CH4),
and nitrous oxide (N2O). The three greenhouse gases have increased in the atmosphere …

Two deep ice cores from central Greenland, drilled in the 1990s, have played a key role in
climate reconstructions of the Northern Hemisphere, but the oldest sections of the cores …

Ocean Biogeochemical Dynamics provides a broad theoretical framework upon which
graduate students and upper-level undergraduates can formulate an understanding of the …

We present a synchronization of the NGRIP, GRIP and GISP2 ice cores onto a master
chronology extending back to 104 ka before present, providing a consistent chronological …

The deep polar ice cores provide reference records commonly employed in global
correlation of past climate events. However, temporal divergences reaching up to several …

An accurate and coherent chronological framework is essential for the interpretation of
climatic and environmental records obtained from deep polar ice cores. Until now, one …

Continuous records of the atmospheric greenhouse gases (GHGs) CO 2, CH 4, and N 2 O
are necessary input data for transient climate simulations, and their associated radiative …
