Sentences with phrase «carbon uptake»

Features of the ocean - carbon cycle that we did not account for may also be changing and could influence ocean carbon uptake in the future.

• Climate change alone will tend to suppress both land and ocean carbon uptake, increasing the fraction of anthropogenic CO2 emissions that remain airborne and producing a positive feedback to climate change.

In tropical ecosystems carbon uptake is reduced at higher temperatures.

An increase in atmospheric CO2 stimulates photosynthesis, and thus carbon uptake.

This map shows the total increase of photosynthesis and carbon uptake by forests caused by all hurricanes in 2004.

According to Ingall, removal of iron by diatom - dominated phytoplankton communities may dampen the intended outcome of enhanced carbon uptake through iron fertilization by reducing the productivity of other phytoplankton, which take up carbon dioxide more efficiently.

According to Dr. Natali, «Our results show that while permafrost degradation increased carbon uptake during the growing season, in line with decadal trends of «greening» tundra, warming and permafrost thaw also enhanced winter respiration, which doubled annual carbon losses.»

We have also estimated carbon uptake on land by taking the known amount of fossil - fuel emissions and subtracting the oceans» uptake and the carbon accumulated in the atmosphere.

These parameters regulate processes such as plant carbon uptake by photosynthesis and how precipitation is separated into evapotranspiration to the atmosphere and river runoff.

Mapping nutrient profiles in rocks to their potential for carbon uptake could help drive conservation considerations.

We could spend more to eliminate using NG, but it would make more sense to spend the resources on eliminating coal and then re-forestation and improving soil carbon uptake in agriculture.

«When you think from a climate point of view, you're not having carbon uptake across all this landscape for many decades when there's very little plant cover,» study co-author Steve Running, a University of Montana professor who models ecosystem functions, said.

The ground breaking research, conducted by scientists at the University of Sheffield, revealed why plants using C4 photosynthesis — a complex set of structural and chemical adaptations that have evolved more than 60 times to boost carbon uptake compared to the ancestral C3 plants — grow so rapidly.

To comment # 16, your confusion is that the estimated 5.7 GT carbon uptake is not out of this year's emissions, it's out of the entire (roughly) 200GT of excess carbon that has built up in the atmosphere since the start of the industrial revolution.

The result was about double that of net productivity, which balances photosynthetic carbon uptake in oceans with carbon released by the respiration of primary producers in the ocean.

Warmer temperatures triggering earlier green sprouts could produce a longer growing season in some places and more photosynthesis — and thus more carbon uptake.
