TL;DR: Evidence that it promotes C sequestration is not compelling, because in essentially all cases where conservation tillage was found to sequester C, soils were only sampled to a depth of 30 cm or less, even though crop roots often extend much deeper.

TL;DR: In this article, the authors present a comprehensive global database for forest ecosystems, which includes carbon budget variables (fluxes and stocks), ecosystem traits (e.g., leaf area index, age), as well as ancillary site information such as management regime, climate, and soil characteristics.

TL;DR: New space-based observations of chlorophyll fluorescence enable an accurate, global, and time-resolved measurement of crop photosynthesis, which is not possible from any other remote vegetation measurement, and indicates that SIF data can help improve global models for more accurate projections of agricultural productivity and climate impact on crop yields.

TL;DR: OCO-2 represents a major advance in satellite SIF remote sensing and suggests that SIF is a powerful proxy for GPP at multiple spatiotemporal scales and that high-quality satellite Sif is of central importance to studying terrestrial ecosystems and the carbon cycle.

TL;DR: In this article, the authors studied how a typical forest ecosystem in the Pacific Northwest reacts to interannual climate variability, including the El Nino/La Nina cycle during the northern hemispheric winters of 1997/1998 and 1998/1999.
