Daytime warming during early grain filling offsets the CO 2 fertilization effect in rice
Increasing concentrations of atmospheric CO 2 are projected to have positive effects on crop photosynthesis and yield (CO 2 fertilization effect, CFE). High-temperature events, such as heatwaves, during sensitive periods can have significant negative impacts on crop yield and quality; however, the combined effects of elevated CO 2 (EC) and short-period elevated temperature (ET) have not been determined in the open field. Here, we show a strong ne…
Soil respiration strongly offsets carbon uptake in Alaska and Northwest Canada
Soil respiration (i.e. from soils and roots) provides one of the largest global fluxes of carbon dioxide (CO 2 ) to the atmosphere and is likely to increase with warming, yet the magnitude of soil respiration from rapidly thawing Arctic-boreal regions is not well understood. To address this knowledge gap, we first compiled a new CO 2 flux database for permafrost-affected tundra and boreal ecosystems in Alaska and Northwest Canada. We then used th…
The biophysical climate mitigation potential of boreal peatlands during the growing season
Peatlands and forests cover large areas of the boreal biome and are critical for global climate regulation. They also regulate regional climate through heat and water vapour exchange with the atmosphere. Understanding how land-atmosphere interactions in peatlands differ from forests may therefore be crucial for modelling boreal climate system dynamics and for assessing climate benefits of peatland conservation and restoration. To assess the bioph…
