Proceedings of the National Academy of Sciences, 2007 What will control future rates of climate change? The carbon cycle is the largest contributor to anthropogenic climate change, yet despite decades of research (1), significant mysteries about its behavior remain. Global analyses show that the Earth system absorbs approximately half of anthropogenic fossil fuel emissions.

Laminarin is a major molecule in the marine carbon cycle
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Microscopic planktonic algae are the base of the marine food web. Although sugars are the most abundant biomolecules in land plants, their concentrations in marine plants appear surprisingly low.

Orbital pacing and secular evolution of the Early Jurassic carbon cycle
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Cyclic variations in Earth’s orbit drive periodic changes in the ocean–atmosphere system at a time scale of tens to hundreds of thousands of years.

Water-Energy Nexus, 2018 Thermoelectric power plants traditionally have required huge volumes of water to condense steam from the turbine exhaust. The complex interdependency between water and energy poses new challenges for policy makers to achieve a safe, secure and ...

Contribution of land use to the interannual variability of the land carbon cycle
Nature Communications, 2020 Understanding the driving mechanisms of the interannual variability (IAV) of the net land carbon balance (S net ) is important to predict future climate–carbon cycle feedbacks.

Mesoscale eddies heterogeneously modulate CO2 fluxes in eddy-rich regions of the Southern Ocean [PDF]
BiogeosciencesMesoscale eddies are known to influence the Southern Ocean biogeochemistry. However, the distinct contributions of cyclonic and anticyclonic eddies to air–sea CO2 fluxes, as well as their longer-term effects remain poorly studied. We present results from

National forest carbon harvesting and allocation dataset for the period 2003 to 2018 [PDF]
Earth System Science DataForest harvesting is one of the anthropogenic activities that most significantly affect the carbon budget of forests. However, the absence of explicit spatial information on harvested carbon poses a huge challenge in assessing forest-harvesting impacts ...

Constraining the climate and ocean pH of the early Earth with a geological carbon cycle model [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance The climate and ocean pH of the early Earth are important for understanding the origin and early evolution of life. However, estimates of early climate range from below freezing to over 70 °C, and ocean pH estimates span from strongly acidic

Ecosystem-driven karst carbon cycle and carbon sink effects
Journal of Groundwater Science and Engineering, 2022 It is recognized that karst processes are actively involved in the current global carbon cycle based on twenty years research, and the carbon sink occurred in karst processes is possibly an important part of “missing sink” in global carbon cycle. In this
