Global Biogeochemical Cycles features research on regional to global biogeochemical interactions, as well as more local studies that demonstrate fundamental implications for biogeochemical processing at regional or global scales. Published papers draw on a wide array of methods and knowledge and extend in time from the deep geologic past to recent historical and potential future interactions. This broad scope includes studies that elucidate human activities as interactive components of biogeochemical cycles and physical Earth Systems including climate. Authors are required to make their work accessible to a broad interdisciplinary range of scientists.
Most people consider climate change to consist only of the warming of the atmosphere, the consequences of which primarily affect land regions. However, this is a human-centered view and does not go far enough.

In the annals of Earth's history, I've stumbled upon a gripping narrative of climate fluctuations and the captivating exchange of carbon. Recent research, which made headlines in the scientific journal Global and Planetary ...
Tropical rainforests store 25%-40% of global soil carbon, though they occupy only 7% of Earth's land area. By functioning as a carbon sink, tropical forests prevent more severe effects from climate change.

Life is teeming nearly everywhere in the oceans, except in certain pockets where oxygen naturally plummets and waters become unlivable for most aerobic organisms. These desolate pools are "oxygen-deficient zones," or ODZs. ...
