Warming climate extends dryness-controlled areas of terrestrial carbon sequestration
At biome-scale, terrestrial carbon uptake is controlled mainly by weather variability. Observational data from a global monitoring network indicate that the sensitivity of terrestrial carbon sequestration to mean annual temperature (T) breaks down at a threshold value of 16°C, above which terrestrial CO₂ fluxes are controlled by dryness rather than temperature. Here we show that since 1948 warm...
متن کاملTerrestrial carbon cycle affected by non-uniform climate warming
173 Temperature regulates almost all biogeochemical processes. Future climate warming will therefore have a profound effect on ecosystem functions and services such as carbon storage1. For example, climate warming influences terrestrial primary production directly by changing the leaf process intensity , but also indirectly by increasing soil nutrient mineralization2–4, changing soil water avai...

Title of Document: VARIABILITY OF TERRESTRIAL CARBON CYCLE AND ITS INTERACTION WITH CLIMATE UNDER GLOBAL WARMING Haifeng Qian, Doctor of Philosophy, 2008 Directed By: Professor Ning Zeng Department of Atmospheric and Oceanic Science Land-atmosphere carbon exchange makes a significant contribution to the variability of atmospheric CO2 concentration on time scales of seasons to centuries. In this...
متن کاملSoil carbon sequestration to mitigate climate change
The increase in atmospheric concentration of CO2 by 31% since 1750 from fossil fuel combustion and land use change necessitates identification of strategies for mitigating the threat of the attendant global warming. Since the industrial revolution, global emissions of carbon (C) are estimated at 270F 30 Pg (Pg = petagram= 10 g = 1 billion ton) due to fossil fuel combustion and 136F 55 Pg due to...
متن کاملImpacts of climate warming on terrestrial ectotherms across latitude.
The impact of anthropogenic climate change on terrestrial organisms is often predicted to increase with latitude, in parallel with the rate of warming. Yet the biological impact of rising temperatures also depends on the physiological sensitivity of organisms to temperature change. We integrate empirical fitness curves describing the thermal tolerance of terrestrial insects from around the worl...
