Sentences with phrase «anthropogenic emissions remains»

The strength of secondary OA sources that are enhanced by interactions of natural and anthropogenic emissions remains an open question that can not be answered by a simple parameterization.

Not exact matches

The precise magnitude of the anthropogenic contribution remains uncertain, but in nine out of ten cases our model results indicate that twentieth - century anthropogenic greenhouse gas emissions increased the risk of floods occurring in England and Wales in autumn 2000 by more than 20 %, and in two out of three cases by more than 90 %.

.40 % of total anthropogenic emissions have remained in the atmosphere.

If the anthropogenic forcing wouldn't keep increasing anymore (because we would manage to suddenly reduce CO2 emission to a level that merely compensates upkeep by sinks, somehow, and the atmospheric concentration would remain constant) then surface temperature would slowly rise until the TOA balance is restored (and then rise some more as slow feedbacks kick in).

The AF is defined as the fraction of anthropogenic carbon emissions which remain in the atmosphere after natural processes have absorbed some of them;

Agriculture and land ‐ use change, mainly deforestation of tropical forests, contribute greatly to anthropogenic greenhouse gas emissions and are expected to remain important during the 21st century.

Simulations with natural forcings only suggest that atmospheric CO2 would have remained around the preindustrial concentration of 280 ppm without anthropogenic emissions.

If, as usually postulated, a fixed fraction (ca. 50 %) of anthropogenic CO2 remains in the atmosphere, a linear trend is generated ONLY WHEN THE YEARLY CO2 EMISSION IS CONSTANT THROUGHOUT.

From the formula, we can see that the carbon footprint area is essentially calculated by dividing total anthropogenic carbon emissions remaining after accounting for ocean uptake (i.e., 72 % of net human emissions) by the rate at which existing forests sequester carbon.

• 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.

We have found evidence that a reduction in the ocean's capacity to absorb anthropogenic CO2 is ominous; a larger fraction of anthropogenic emissions will remain in the atmosphere, exacerbating the global warming due to industrial activity.
