TL;DR: The mechanisms and impacts of climate extremes on the terrestrial carbon cycle are explored, and a pathway to improve the understanding of present and future impacts ofClimate extremes onThe terrestrial carbon budget is proposed.

TL;DR: It is shown that limited phosphorus and nitrogen availability are likely to jointly reduce future carbon storage by natural ecosystems during this century and if phosphorus fertilizers cannot be made increasingly accessible, the crop yields projections of the Millennium Ecosystem Assessment imply an increase of the nutrient deficit in developing regions.

TL;DR: It is found that ecosystem responses can exceed the duration of the climate impacts via lagged effects on the carbon cycle, and forests are expected to exhibit the largest net effect of extremes due to their large carbon pools and fluxes, potentially large indirect and lagged impacts, and long recovery time to regain previous stocks.

TL;DR: The interannual covariations of the satellite-derived normalized difference vegetation index (NDVI) with Tmax and Tmin over the Northern Hemisphere suggest that asymmetric diurnal warming leads to a divergent response of Northern Hemisphere vegetation growth and carbon sequestration to rising temperatures.

TL;DR: Synthesizing experiments from around the world show that CO2 fertilization is best explained by a simple interaction between nitrogen availability and mycorrhizal association, and the incorporation of myCorrhizae in global carbon cycle models is feasible, and crucial if to accurately project ecosystem responses and feedbacks to climate change.
