Reversing the Trend Terrestrial net primary productivity (NPP, the amount of atmospheric carbon fixed by plants and accumulated as biomass) increased from 1982 through 1999, which has been attributed to factors such as nitrogen deposition, CO2 fertilization, forest regrowth, and climatic changes. Zhao and Running (p. 940) used satellite data to estimate global terrestrial NPP over the past decade and found that the earlier trend has been reversed and that NPP has been decreasing. Combining this… 

Large‐Scale Droughts Responsible for Dramatic Reductions of Terrestrial Net Carbon Uptake Over North America in 2011 and 2012

Recently, severe droughts that occurred in North America are likely to have impacted its terrestrial carbon sink. However, process‐based understanding of how meteorological conditions prior to the

Drought-Induced Reduction in Net Primary Productivity across Mainland China from 1982 to 2015

The spatiotemporal features of NPP and the influences of drought on NPP across mainland China from 1982 to 2015 are explored using the Carnegie Ames Stanford Application (CASA) model and the standardized precipitation evapotranspiration index (SPEI).

Decreasing net primary production due to drought and slight decreases in solar radiation in China from 2000 to 2012

Terrestrial ecosystems have continued to provide the critical service of slowing the atmospheric CO2 growth rate. Terrestrial net primary productivity (NPP) is thought to be a major contributing

Decadal drought deaccelerated the increasing trend of annual net primary production in tropical or subtropical forests in southern China

Previous investigations have identified that the effects of climate change on net primary production (NPP) of global forests have varied both spatially and temporally, and that warming has increased

Projected Increases in Global Terrestrial Net Primary Productivity Loss Caused by Drought Under Climate Change

Understanding present and future impacts of drought on the terrestrial carbon budget is of great significance to the evaluation of terrestrial ecosystem disturbance and terrestrial carbon sink. Here,

Increasing impacts of extreme droughts on vegetation productivity under climate change

Terrestrial gross primary production (GPP) is the basis of vegetation growth and food production globally1 and plays a critical role in regulating atmospheric CO2 through its impact on ecosystem

Too early to infer a global NPP decline since 2000

The global terrestrial carbon cycle plays a pivotal role in regulating the atmospheric composition of greenhouse gases. It has recently been suggested that the upward trend in net primary production

Dynamic changes of terrestrial net primary production and its feedback to evapotranspiration

Earth experienced dramatic environmental changes in the recent 15 years (2000-2014). The 9 past decade has been the warmest in the instrumental record, which significantly influences the global 10

Response of Global Terrestrial Carbon Fluxes to Drought from 1981 to 2016

Precipitation plays a dominant role in regulating terrestrial carbon fluxes. In concert with global warming, aridity has been increasing during recent decades in most parts of the world. How global

Recent patterns of terrestrial net primary production in africa influenced by multiple environmental changes

Abstract Terrestrial net primary production (NPP) is of fundamental importance to food security and ecosystem sustainability. However, little is known about how terrestrial NPP in African ecosystems



Climate-Driven Increases in Global Terrestrial Net Primary Production from 1982 to 1999

It is indicated that global changes in climate have eased several critical climatic constraints to plant growth, such that net primary production increased 6% (3.4 petagrams of carbon over 18 years) globally.

Net carbon dioxide losses of northern ecosystems in response to autumn warming

Simulation and observations indicate that northern terrestrial ecosystems may currently lose carbon dioxide in response to autumn warming, with a sensitivity of about 0.2 PgC °C-1, offsetting 90% of the increased carbon dioxide uptake during spring.

Drier summers cancel out the CO2 uptake enhancement induced by warmer springs.

It is shown that this lower summer uptake is probably the result of hotter and drier summers in both mid and high latitudes, demonstrating that a warming climate does not necessarily lead to higher CO(2) growing-season uptake, even in high-latitude ecosystems that are considered to be temperature limited.

Drought Sensitivity of the Amazon Rainforest

Records from multiple long-term monitoring plots across Amazonia are used to assess forest responses to the intense 2005 drought, a possible analog of future events that may accelerate climate change through carbon losses and changed surface energy balances.

Reduction of forest soil respiration in response to nitrogen deposition

The use of fossil fuels and fertilizers has increased the amount of biologically reactive nitrogen in the atmosphere over the past century. As a consequence, forests in industrialized regions have

Trends in the sources and sinks of carbon dioxide

Efforts to control climate change require the stabilization of atmospheric CO2 concentrations. This can only be achieved through a drastic reduction of global CO2 emissions. Yet fossil fuel emissions

Interannual variability in global biomass burning emissions from 1997 to 2004

Biomass burning represents an important source of atmospheric aerosols and greenhouse gases, yet little is known about its interannual variability or the underlying mechanisms regulating this

Acceleration of global warming due to carbon-cycle feedbacks in a coupled climate model

Results from a fully coupled, three-dimensional carbon–climate model are presented, indicating that carbon-cycle feedbacks could significantly accelerate climate change over the twenty-first century.

Evolution of carbon sinks in a changing climate.

Analysis of the results in the context of comparable models suggests that destabilization of the tropical land sink is qualitatively robust, although its degree is uncertain.

Amazon rainforests green‐up with sunlight in dry season

Metabolism and phenology of Amazon rainforests significantly influence global dynamics of climate, carbon and water, but remain poorly understood. We analyzed Amazon vegetation phenology at multiple
