  • The cause of the increase in atmospheric methane from 375 p.p.b.v. during the last ice age to 680 p.p.b.v. at the onset of Industrialization remains uncertain. Here, using an Earth system model, the authors show that we cannot reconcile this rise based on our current understanding of natural methane sources.

  • Analyses of ice-core carbon isotopes show that variations in atmospheric CO2 levels during the past millennium are controlled by changes in land reservoirs. But whether climate variations or human activity were mainly responsible is uncertain.

  • Erosion of agricultural land is estimated to have resulted in a cumulative net uptake of 78 ± 22 Pg C on land (6000 bc–2015 ad), offsetting 37 ± 10% of generally recognized C emissions resulting from anthropogenic land cover change.

  • Tropical forest restoration has the potential to remove large amounts of CO2 from the atmosphere, but the climate mitigation potential could be threatened by climate change impacts. This study shows that carbon sequestered in restored forests is predominantly safe under a range of future scenarios.

  • We reconstruct the spatial distribution and timing of wetland loss through conversion to seven human land uses between 1700 and 2020, elucidating the magnitude and land-use drivers of global wetland losses to improve assessments of wetland loss impacts.

  • Projecting and managing the feedback between tropical deforestation and global Earth system dynamics, and identifying potential critical thresholds or tipping points, will be key to our species’ future on this planet. By understanding the major historical processes that underpin the origins of this interaction, and bringing natural and social systems together in interdisciplinary models, we can evaluate the degree to which past human impacts on tropical forests resulted in observable planetary ramifications that have left legacies for the twenty-first century and beyond.

  • Homo erectus adapted to hyper-arid climatic conditions one million years ago through the strategic use of rivers and ponds, and this facilitated geographic expansion within and beyond Africa, as shown by multi-proxy data from Oldupai Gorge, Tanzania.
