Sentences with phrase «net ecosystem carbon»

We estimate a 30 per cent reduction in gross primary productivity over Europe, which resulted in a strong anomalous net source of carbon dioxide (0.5 Pg C yr - 1) to the atmosphere and reversed the effect of four years of net ecosystem carbon sequestration6.

Vegetation changes associated with a biome shift, which is facilitated by intensification of the fire regime, will modify surface energy budgets, and net ecosystem carbon balance, permafrost thawing and methane emissions, with net feedbacks to additional climate change.

The land ecosystems have, of course, a high turnover of carbon, but (unlike humans) do not add any net CO2 to the atmosphere.

Using the NDVI, one team this year reported that «over the last few decades of the 20th century, terrestrial ecosystems acted as net carbon sinks,» i.e., they absorbed more carbon than they were emitting, and «net greening was reported in all biomes,» though the effect had slowed down in recent years.

The role of the region's forests as a net absorber of carbon is at risk from disruptions to forest ecosystems, in part due to climate change.

Recent work has suggested that eutrophication might «reverse» the carbon budget of lakes and reservoirs (i.e., shifting the ecosystem from net heterotrophy to net autotrophy) by converting large amounts of CO2 to organic matter via elevated primary production (Pacheco et al. 2013).

SCC is effectively an estimate of the direct effects of carbon emissions on the economy, and takes into consideration such factors as net agricultural productivity loss, human health effects, property damages from sea level rise, and changes in ecosystem services.

To look at the broader benefits of carbon finance, it would be better to use total revenue rather than net income as well as incorporate some of the other ecosystem services afforded by intact forest.

Healthy forests play a key role in global ecosystems as they contain much of the terrestrial biodiversity on the planet and act as a net sink for capturing atmospheric carbon.

Accounting for changes in all carbon stocks in all areas would yield the net carbon exchange between terrestrial ecosystems and the atmosphere (NBP).

One mechanism by which fossil fuel emissions increase carbon uptake is by fertilizing the biosphere via provision of nutrients essential for tissue building, especially nitrogen, which plays a critical role in controlling net primary productivity and is limited in many ecosystems.

Christiansen CT, Lafreniére MJ, Henry GHR, Grogan P (2018) Long - term deepened snow promotes tundra evergreen shrub growth and summertime ecosystem net CO2 gain, but reduces soil carbon and nutrient pools.

Global warming is changing the movement of carbon within northern ecosystems to the point where the Arctic could become a net source, rather than sink, of greenhouse gas emissions.

The net uptake of carbon in terrestrial ecosystems has, over the past 5 decades, fluctuated between zero in some years to nearly 6 Gt C yr − 1 in others [29].

The social cost of carbon includes, for example, changes in net agricultural productivity and human health, property damage from increased flood risk, energy system costs, and the value of ecosystem services lost because of climate change.

This new concept of anthropogenic impacts on seawater pH formulated here accommodates the broad range of mechanisms involved in the anthropogenic forcing of pH in coastal ecosystems, including changes in land use, nutrient inputs, ecosystem structure and net metabolism, and emissions of gases to the atmosphere affecting the carbon system and associated pH. The new paradigm is applicable across marine systems, from open - ocean and ocean - dominated coastal systems, where OA by anthropogenic CO2 is the dominant mechanism of anthropogenic impacts on marine pH, to coastal ecosystems where a range of natural and anthropogenic processes may operate to affect pH.

According to Mr. Heikki Simola Finnish Association for Nature Conservation Finnish forest management has made Finnish forest and mire ecosystems as a considerable net source of carbon into the atmosphere for decades.

Net primary production (the amount of carbon converted to plant biomass) is far less than what would be absorbed from a natural forest ecosystem, and the carbon does not remain in the system very long.
