Agriculture has contributed nearly as much to climate change as deforestation by intensifying global warming, according to US research that has quantified the amount of carbon taken from the soil b

The world’s forests play a pivotal role in the mitigation of global climate change. By photosynthesis they remove CO2 from the atmosphere and store carbon in their biomass. While old trees are generally acknowledged for a long carbon residence time, there is no consensus on their contribution to carbon accumulation due to a lack of long-term individual tree data. Tree ring analyses, which use anatomical differences in the annual formation of wood for dating growth zones, are a retrospective approach that provides growth patterns of individual trees over their entire lifetime.

Based on carbon dioxide concentrations at a location and wind speed, scientists trace particles back to their sources to identify whether the country is an emitter or a carbon sink, say Eurasian re

Ever increasing power demand coupled with CO2 emission from coal-based power plants is a critical challenge for worldwide energy sector. This is even more critical for a country like India where a large coal reserve exists and about 60% of the total power produced is from coal. Meeting energy demand and simultaneously satisfying CO2 emissions target, India has to develop power from coal using more advanced technology than existing subcritical pulverized coal fired one. IGCC with CO2 capture emerges as a prospective option for using coal with reduced CO2 emissions.

Though biodiversity and carbon storage have been linked in past forest research, a new study using Amazon, Congo and Borneo data found no consistent correlation.

NEW DELHI: If US President Donald Trump decides to withdraw from the Paris Agreement, it will dampen the spirit of global climate action as many countries not only look at America for support for t

Ecosystem carbon carrying capacity (CCC) is determined by prevailing climate and natural disturbance regimes, conditions that are projected to change significantly. The interaction of changing climate and its effects on disturbance regimes is expected to affect forest regeneration and growth, which may diminish forest carbon (C) stocks and uptake. We modeled landscape C dynamics over 590 years along the latitudinal gradient of the U.S. Sierra Nevada Mountains under climate and area burned by large wildfires projected by late 21st century.

In the Tibetan Plateau, climate change is increasing the carbon concentrations within the upper layers of permafrost soils, a study has shown.

Growth in terrestrial gross primary production (GPP)—the amount of carbon dioxide that is ‘fixed’ into organic material through the photosynthesis of land plants—may provide a negative feedback for climate change. It remains uncertain, however, to what extent biogeochemical processes can suppress global GPP growth. As a consequence, modelling estimates of terrestrial carbon storage, and of feedbacks between the carbon cycle and climate, remain poorly constrained.

This publication provides an overview to decision-makers and practitioners of the main scientific facts and information regarding the current knowledge and knowledge gaps on Soil Organic Carbon.
