Weathering of organic carbon contained in sedimentary rocks (petrogenic OC, OCpetro) is an important control on the concentrations of carbon dioxide (CO2) and oxygen in the atmosphere. Of particular significance are steep mountainous catchments, wher...

Scientific Reports, 11(1), Article 11857. https://doi.org/10.1038/s41598-021-90795-2

Human mobility and migration are thought to have played essential roles in the consolidation and expansion of sedentary villages, long-distance exchanges and transmission of ideas and practices during the Neolithic transition of the Near East. Few is... Read More about Multi-isotope evidence of population aggregation in the Natufian and scant migration during the early Neolithic of the Southern Levant.

J., Zhang, M., Marwan, N., Macpherson, C. G., Baldini, L. M., Xiao, T., Peterkin, P. J. L., Awe, J., & Haug, G. H. (2015). Aerosol forcing of the position of the intertropical convergence zone since AD1550. Nature Geoscience, 8(3), 195-200. https://doi.org/10.1038/ngeo2353

The position of the intertropical convergence zone is an important control on the distribution of low-latitude precipitation. Its position is largely controlled by hemisphere temperature contrasts1, 2. The release of aerosols by human activities may...
