Forests are retaining carbon for less and less time

19 de November 2019CREAF

Published in the journal PNAS (Proceedings of the National Academy of Sciences), a study to which the Spanish National Research Council (CSIC) and CREAF have contributed has revealed that the time for which forests retain carbon has fallen by between 0.2% and 0.3% every year in recent decades. Plant mortality is rising due to higher carbon dioxide (CO2) levels and, in particular, warming and droughts. The time in question, which is termed carbon turnover time, is a relevant factor in climate change projections as it is indicative of carbon sinks’ capacity to retain carbon.

Achieving the COP21 agreements is currently far-fetched

9 de June 2017Albert Naya i Díaz

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.

Life on Earth barely extends over its surface. But organisms have been able to transform its climate for millions of years. Now, humans seem to reach it again in a record time.

Increased ozone levels reduce flowers’ sex appeal

17 de September 2015Anna Ramon Revilla

New research finds that as climate change increases ozone levels, pollinators will have a harder timing finding plants that feed them. That’s going to be a problem for the bees that pollinate a third of the world’s food supply. Flowers and other plants rely on microscopic scent molecules to attract the bees and other pollinators that feed on them. Climate change is going to disrupt that process, mostly because of ground-level ozone, which is projected to increase over the coming decades. The study, published in the journal New Phytologist, found that flowers’ fragile scent molecules break down more quickly as they are exposed to greater levels of ozone. >> Read the full article from Takepart.com here
