  • Although the correlation between greenhouse gases and temperature is well documented, it is difficult to show causality from the data. This study uses insight from dynamical systems theory to show that internal Earth system mechanisms largely control climate dynamics, rather than orbital forcing, and temperature does have a reinforcing feedback on greenhouse-gas concentrations.

  • The rate of Arctic coastal permafrost erosion is predicted to increase up to 3 times by 2100. Here the authors model how organic matter released from coastal permafrost erosion will reduce the CO2 sink capacity of the Arctic Ocean and lead to positive feedbacks on climate.

  • Future Arctic methane emissions may be less dependent on soil hydrology. Here, this study indicates that if the high latitudes maintain wet conditions, the cooling effects could limit the increase in methane, resulting in emissions similar to a warmer dry scenario with a higher substrate availability.

  • Coastal erosion in the Arctic is caused by permafrost thaw and wave abrasion enhanced by sea ice melt, both of which will increase under climate change. Projections of erosion rate across the Arctic indicate that mean erosion rates will rise beyond historical precedent over the twenty-first century.

  • Since the early 1980s, remotely sensed data has shown the Earth to be slowly greening. Climate change, CO2 fertilization and land-use change are competing explanations. Using satellite data from 2000–2017, this study finds striking greening of both China and India, driven primarily by land-use change, with forest growth and cropland intensification more important in China and cropland more important in India.

  • The terrestrial biosphere absorbs a large fraction of emitted CO2, and thus, plays a critical role in climate change projections. Here, the authors use satellite leaf area and in-situ CO2 measurements to show that most Earth system models largely underestimate photosynthetic carbon fixation in high latitudes.

  • Accurate representation of permafrost carbon emissions is crucial for climate projections, yet current Earth system models inadequately represent permafrost carbon. Sustained funding opportunities are needed from government and private sectors for prioritized model development.
