Sentences with phrase «for nitrogen deposition»

Finally, for nitrogen deposition, a decrease can be observed across the RCPs for most high - income regions.

Not exact matches

We don't have any nonimpacted systems, and so the question now is how do you keep stuff as natural as possible, given the fact you do have regional air pollution, whether it be nitrogen deposition or dust or whatever — and that's really gonna be hard for the parks.

Glaser et al. show that dust deposition mediated by frequent tropical storms was an important source of nutrients for the Everglades until about 2800 years ago, when a climatic shift in the tropical Atlantic and Gulf of Mexico led to weather patterns that sharply decreased the level of dust inputs and led to a drier climate and a gradual loss of soil phosphorus, carbon, and nitrogen.

For example, controlling fossil - fuel combustion could reduce atmospheric nitrogen deposition on both land and sea.

I'd suspect that a change in soil microbiology might also change the way the soil holds onto water — and we know we're getting changes due to increased deposition of nitrogen, for example, from the air.

Progress is however markedly slower for eutrophication, which is caused by excess nitrogen deposition resulting from emissions of nitrogen oxides (NOx) and ammonia (NH3).

Here we construct a database of worldwide RS observations matched with high - resolution historical climate data and find a previously unknown temporal trend in the RS record after accounting for mean annual climate, leaf area, nitrogen deposition and changes in CO2 measurement technique.

While «strip - bark» samples should be avoided for temperature reconstructions, attention should also be paid to the confounding effects of anthropogenic nitrogen deposition (Vitousek et al. 1997), since the nutrient conditions of the soil determine wood growth response to increased atmospheric CO2 (Kostiainen et al. 2004).

While «strip - bark» samples should be avoided for temperature reconstructions, attention should also be paid to the confounding effects of anthropogenic nitrogen deposition (Vitousek et al. 1997)...

However, in many developing regions, an increase in nitrogen deposition is projected for the end of the 21st century, mostly related to the projected increases in NH3 emissions due to agricultural activities.

Scientific confidence of the occurrence of climate change include, for example, that over at least the last 50 years there have been increases in the atmospheric concentration of CO2; increased nitrogen and soot (black carbon) deposition; changes in the surface heat and moisture fluxes over land; increases in lower tropospheric and upper ocean temperatures and ocean heat content; the elevation of sea level; and a large decrease in summer Arctic sea ice coverage and a modest increase in Antarctic sea ice coverage.

It is important to note that these impacts do not take account of ancillary stresses on species due to over-harvesting, habitat destruction, landscape fragmentation, alien species invasions, fire regime change, pollution (such as nitrogen deposition), or for plants the potentially beneficial effects of rising atmospheric CO2.

Other researchers used historical (real - world) data for land use, atmospheric CO2 concentration, nitrogen deposition, fertilization, ozone levels, rainfall and climate, to develop a computer model that simulates plant growth responses for southern US habitats from 1895 to 2007.

The site, designed to exploit grasslands as models for understanding how ecosystems may respond to climate change, hosts a number of studies of the potential effects from elevated atmospheric carbon dioxide, elevated temperature, increased precipitation, and increased nitrogen deposition.
