According to a study published recently in the journal PNAS, climate change has caused forests to alter the way they grow, in that they only take advantage of the fertilizing effect of carbon dioxide (CO2) to grow faster if they have plenty of water.
A study led by CREAF shows that decreases in pollutant deposition and the increase in atmospheric CO2 have stimulated photosynthesis and carbon sequestration in forests. Therefore, it is crucial to understand how carbon circulates in the atmosphere, in living organisms, oceans, and soils in order to anticipate the effects of climate change.
The Global Carbon Budget 2017 has analyzed carbon emission sources and sinks worldwide. This year the researcher Benjamin Stocker from CREAF has collaborated in the report contributing and preparing data about how the change in the use we give to the territory has affected CO₂ emissions.
The COP21 set the maximum temperature increase for 2100 at 1.5° C. The only scenario which would allow achievement of this goal would require vastly reducing human CO2 emissions, significantly increasing the prominence of renewable energies, and the use of some type of artificial carbon sequestration technology.
An international team of researchers co-led by Josep Peñuelas (CSIC and CREAF) has developed a new method for monitoring changes in the photosynthetic activity of perennial conifers throughout the year. This new technique, based on the analysis of remote sensing images captured by satellites, will improve global models of atmospheric carbon capture and permit more precise predictions about climate change.
The journal Nature has today published a study which had the participation of CSIC scientists at CREAF, Marc Estiarte and Josep Peñuelas, which demonstrates the relationship between the release of carbon from soils and the acceleration of climate change.
CREAF researchers uncover how climate change-provoked substitutions of pines with holm oak affect soil respiration10 de March 2016Albert Naya i Díaz
Scots pine is the tree species with the greatest latitudinal distribution between Siberia and the Iberian Peninsula. The death of these pines due to drought does not affect CO2 emissions from forest soil.
