Sentences with phrase «additional plant growth»

Biofuels can only reduce greenhouse gases if they result in additional plant growth, or if they in effect generate additional useable biomass by capturing waste material that would otherwise decompose anyway.

So bioenergy only reduces greenhouse gases if it results from additional plant growth or in some other way uses carbon that would not otherwise be stored (for example, by using the waste material left after timber harvest that would decompose rapidly anyway).

They implicitly assume that it all results from additional plant growth when in fact it often occurs by displacing stored carbon, such as forests.

Not exact matches

The researchers identified several reasons for this: The new gene constructs interfere with the plant's own gene for producing growth hormones, and the additional gene constructs were not, as intended, active solely in the kernels, but also in the leaves.

Both Haverstraw Town Supervisor Howard Phillips and Rockland Business Association President Hector May have expressed support for the plant, arguing growth in the county would eventually require additional sources of water and that it would bring rateables to the town.

Global simulations conducted by the team found that microbial responses to enhanced root activity under rising CO2, while depending on plant species, climate and soil mineralogy, led to a loss of global soil carbon stocks that counteracted the additional carbon storage resulting from increased plant growth in many regions of the world.

In the past, some people have argued that the increase in carbon dioxide (CO2) in the air would be partially offset by an increase in plant growth, caused by that additional (CO2): increased CO2 concentrations in the atmosphere should work like extra fertilizer and lead to increased plant growth.

They supplied additional bacteria by spraying it on the plants during other stages of growth.

, while depending on plant species, climate and soil mineralogy, led to a loss of global soil carbon stocks that counteracted the additional carbon storage resulting from increased plant growth in many regions of the world.

And are there any offsetting additional amounts of terrestial carbon (such as new forests or plant growth, or is this accounted for in the 3rd figure?).

(2) Hoskins: «Additional atmospheric CO2 significantly improves all plant growth and thus food production.»

A CO2 pulse in the atmosphere will take centuries to finally return to original levels, and that is completely ignoring any potential feedbacks from other parts of the system (ie temperatures raised for centuries could result in massve methane releases and loss of signficant low albedo ice sheets etc.) The experiments I am aware of that show improved plant growth in elevated CO2 levels require that all additional biological needs are amply provided for.

The additional CO2 has caused a 60 % increase in plant growth.

For example, additional capacity beyond existing plants is only required by 2020 if power generation growth exceeds 4 % year and coal plants are run at utilisation rate of 45 % or less.

Our results resolve conflicting assumptions about the nature of tree growth, inform efforts to undertand and model forest carbon dynamics, and have additional implications for theories of resource allocation11 and plant senescence12.

Consideration of an upper thermal limit and interactions with plant growth thresholds in additional climatic variables resulted in the opposite trend: global decreases in the number of suitable plant growing days by 2100 (Fig 2).

Most climate models used for the latest Intergovernmental Panel on Climate Change (IPCC) report assume that enough additional nitrogen and phosphorus would be available for extra plant growth.

Carbon is a raw material for photosynthesis, and new carbon may accelerate plant growth, resulting in additional uptake.
