For plants, it seems that elevated levels of CO2 [carbon dioxide] will increase plant biomass, water use efficiency, and reproductive effort.

Not exact matches

Conversion of natural vegetation to agriculture is a major source of CO2, not only due to losses of plant biomass but also, increased decomposition of soil organic matter caused by disturbance and energy costs of various agricultural practices such as fertilization and irrigation.

As productivity continues to increase, as in boreal forests, plant biomass (the total mass of living matter of a particular type) increases, herbivore biomass increases, and ecosystems become capable of sustaining a third trophic level — the predators — with this level controlling herbivores.

«Plants supply biomass which forms the beginning of the food chain, but insects act as pollinators and soil organisms increase soil fertility through the breakdown and retention of chemical elements such as phosphorus.

Walls that are covered in plants could increase the overall stocks of biomass, and thus the proportion of of carbon stored in terrestrial ecosystems compared to in the atmosphere.

However, more atmospheric CO2 is predicted to increase crop biomass and subsequent yields, and reduce water use by allowing plant stomates to open over shorter periods, thus assimilating the same amount of atmospheric CO2 while conserving moisture (Cutforth et al. 2007).

Complete restoration of deforested areas is unrealistic, yet 100 GtC carbon drawdown is conceivable because: (1) the human - enhanced atmospheric CO2 level increases carbon uptake by some vegetation and soils, (2) improved agricultural practices can convert agriculture from a CO2 ource into a CO2 sink [174], (3) biomass - burning power plants with CO2 capture and storage can contribute to CO2 drawdown.

There was some bad news for Drax recently as the UK government decided that biomass subsidies would not keep climbing as the «carbon price floor» — levied on fossil fuel production (and due to rise further)-- on electricity consumption has caused a backlash from manufacturers, consumer groups and energy suppliers who are concerned that the «tax will push up prices, make the UK uncompetitive and force the premature closure of coal - fired power plants, increasing the risk of blackouts.»

net primary production the increase in plant biomass or carbon of a unit of a landscape; gross primary production (all carbon fixed through photosynthesis) minus plant respiration equals net primary production

December 17, 2017 Plant diversity enhances soil microbial biomass, particularly soil fungi, by increasing root - derived organic inputs.

There's the implications of this too: Dr David Evans who consulted full time for the Australian Green - house Office, now the Dept of Climate Change,1999 - 2005, modelling carbon in plants, mulch, soil and agricricultural products said in an interview, that satellite data over the last 2 decades shows that the amount of plant biomass has increased by 6 %.

Recent evidence shows plants have increased in biomass by 25 % in the last decade.

The revised plan significantly reduced the number of coal plants in the pipeline and incorporated Nguy Thi's recommendation to increase renewable energy — such as wind, solar, and biomass — to 21 % of the total energy plan by 2030.

This greater plant growth means more carbon is stored in the increasing biomass, so it was previously thought the greening would result in more carbon dioxide being taken up from the atmosphere, thus helping to reduce the rate of global warming.

There is little doubt that nearly all plants respond positively to atmospheric CO2 enrichment, experiencing increases in photosynthesis, biomass and water use efficiency, to name but a few of the most commonly reported benefits.

Where precipitation decreases were projected, the results were more complex due largely to interactions between plant biomass, runoff, and erosion, and either increases or decreases in overall erosion could occur.

Increased weed and pest pressure associated with longer growing seasons and warmer winters will be an increasingly important challenge; there are already examples of earlier arrival and increased populations of some insect pests such as corn earworm.64 Furthermore, many of the most aggressive weeds, such as kudzu, benefit more than crop plants from higher atmospheric carbon dioxide, and become more resistant to herbicide control.72 Many weeds respond better than most cash crops to increasing carbon dioxide concentrations, particularly «invasive» weeds with the so - called C3 photosynthetic pathway, and with rapid and expansive growth patterns, including large allocations of below - ground biomass, such as roots.73 Research also suggests that glyphosate (for example, Roundup), the most widely - used herbicide in the United States, loses its efficacy on weeds grown at the increased carbon dioxide levels likely to occur in the coming decades.74 To date, all weed / crop competition studies where the photosynthetic pathway is the same for both species favor weed growth over crop growth as carbon dioxide is incIncreased weed and pest pressure associated with longer growing seasons and warmer winters will be an increasingly important challenge; there are already examples of earlier arrival and increased populations of some insect pests such as corn earworm.64 Furthermore, many of the most aggressive weeds, such as kudzu, benefit more than crop plants from higher atmospheric carbon dioxide, and become more resistant to herbicide control.72 Many weeds respond better than most cash crops to increasing carbon dioxide concentrations, particularly «invasive» weeds with the so - called C3 photosynthetic pathway, and with rapid and expansive growth patterns, including large allocations of below - ground biomass, such as roots.73 Research also suggests that glyphosate (for example, Roundup), the most widely - used herbicide in the United States, loses its efficacy on weeds grown at the increased carbon dioxide levels likely to occur in the coming decades.74 To date, all weed / crop competition studies where the photosynthetic pathway is the same for both species favor weed growth over crop growth as carbon dioxide is incincreased populations of some insect pests such as corn earworm.64 Furthermore, many of the most aggressive weeds, such as kudzu, benefit more than crop plants from higher atmospheric carbon dioxide, and become more resistant to herbicide control.72 Many weeds respond better than most cash crops to increasing carbon dioxide concentrations, particularly «invasive» weeds with the so - called C3 photosynthetic pathway, and with rapid and expansive growth patterns, including large allocations of below - ground biomass, such as roots.73 Research also suggests that glyphosate (for example, Roundup), the most widely - used herbicide in the United States, loses its efficacy on weeds grown at the increased carbon dioxide levels likely to occur in the coming decades.74 To date, all weed / crop competition studies where the photosynthetic pathway is the same for both species favor weed growth over crop growth as carbon dioxide is incincreased carbon dioxide levels likely to occur in the coming decades.74 To date, all weed / crop competition studies where the photosynthetic pathway is the same for both species favor weed growth over crop growth as carbon dioxide is increasedincreased.72

Positive effects of climate change may include greener rainforests and enhanced plant growth in the Amazon, increased vegetation in northern latitudes and possible increases in plankton biomass in some parts of the ocean.

Adding another 300 ppm of CO2 to the air has been shown by literally thousands of experiments to greatly increase the growth or biomass production of nearly all plants.

There would have been a large reduction of plant biomass, and consequently a large increase in CO2 levels, over a relatively short period.

If increased CO2 levels are mostly bad for plant life, this would have reduced the plant biomass still further, and so on.

The balance is going somewhere else and the best science says most of it is going into an increase in global plant biomass.

We can be certain that higher levels of CO2 will result in increased plant growth and biomass.

Nutrients will be released too, having been stored for thousands of years, so plant growth will be electric, with increases in annual biomass production and productivity.

With other waste - to - energy plants competing for feedstocks, a shift to more sustainable agriculture requiring more biomass returned to the soil, and (yeah, I am an optimist) an increasing realization that we can't keep wasting food anyway, there will inevitably come a time when organic «waste» will be seen as an expensive, valuable resource.

Their projections show an increase to growing season length, vegetation productivity (outside of the southeastern US) and biomass, as well as increased plant water - use efficiency.They also find that vegetation feedbacks may increase warming in summer at higher latitudes and reduce summer warming at lower latitudes.

While gasification would increase the energy efficiency of pulp and paper plants, the industry as a whole would not become a net exporter of biomass energy (Farahani et al., 2004).

That means if plants around the world continue to adjust to rising carbon dioxide concentrations, increasing their biomass on a global scale, they could actually help offset some of our human carbon emissions by removing more carbon dioxide from the air.
