Sentences with phrase «global land carbon sink»

«The simple relationship between the temperature and the global land carbon sink should be treated with caution, and not be used to infer ecological processes and long - term predictions» adds Dr. Reichstein, head of the Department.

Co-author Professor Peter Cox, of the University of Exeter, summarises the consequences of the study: «despite nutrient limitations in some regions, our study indicates that CO2 - fertilization of photosynthesis is currently playing a major role in the global land carbon sink.

«The implications for the global carbon sink are profound,» said Dr Andrew Marshall from the University's Environment Department and Director of Conservation Science at Flamingo Land.

Discussions on whether temperature or water availability is driving the strength of these variations in the land carbon sink have been highly contested with these year - to - year changes of the carbon balance seemingly related to global or tropical temperatures.

If the recent «slowdown» in global surface warming is reversing, the stronger land carbon sink seen in recent years may weaken again, and the rise in CO2 may quicken again.

The elements that I believe are key to a successful agreement in Copenhagen include: • Strong targets and timetables from industrialized countries and differentiated but binding commitments from developing countries that put the entire world under a system with one commitment: to reduce emissions of carbon dioxide and other global warming pollutants that cause the climate crisis; • The inclusion of deforestation, which alone accounts for twenty percent of the emissions that cause global warming; • The addition of sinks including those from soils, principally from farmlands and grazing lands with appropriate methodologies and accounting.

``... estimate that variations in diffuse fraction, associated largely with the «global dimming» period6, 7, 8, enhanced the land carbon sink by approximately one - quarter between 1960 and 1999.

For more than a decade, researchers have struggled and failed to balance global carbon budgets, which must balance carbon emissions to the atmosphere from fossil fuels (6.3 Pg per year; numbers here from Skee Houghton at Woods Hole Research Center) and land use change (2.2 Pg; deforestation, agriculture etc.) with carbon dioxide accumulation in the atmosphere (3.2 Pg) and the carbon sinks taking carbon out of the atmosphere, especially carbon dioxide dissolving in Ocean surface waters (2.4 Pg).

On a global scale, forests that serve as invaluable carbon «sinks» — lands that absorb more carbon than they emit — are under siege.

Because these lands play such a vital role as carbon sinks, it's no surprise that their destruction is partly responsible for the emissions from land use changes that add up to nearly 18 percent of the total global warming effect.

Having retrieved the original article (Canadell et al., 2007, PNAS online) it's written (p. 3) that 65 + / -16 % of... d ² CO2 / dt ² (translation of «increase of atmospheric CO2 growth rate») is attributed to «the increase in the global economy», the remaining 35 + / -16 % being attributed to «the increase in carbon intensity in the global economy» and 18 + / -15 % to «the decrease in the efficiency of the lands and ocean sinks in removing anthropogenic CO2».
