Madrid The temperature rise due to climate change had caused a breakthrough in the emergence of the plants, very positive so that they will set more carbon, but a team of scientists has just discovered that this trend has slowed, according to an article published today in the journal Nature.
The study, which has been used as reference data in European forests last thirty years, it notes that despite the warming continues, European forests and spring do not advance much as they did in the 80s.
He explains in an interview with Efe one of the authors research, Josep Penuelas, director of Global Ecology Unit of the Center for Ecological Research and Forestry Applications (CREAF) and research professor at the Higher Council for Scientific Research (CSIC). So far, most scientific theories pointed to the advancement of the spring caused by climate change was making the trees sprout more and more advance.
“One of the symptoms of climate change acting on the vegetation is changing phenology, life cycle of organisms. In this case the most significant is when the leaves come out because if they appear before fix more carbon, “said Peñuelas. The reference value since 1980 is that for every degree increase in temperature over the output of the leaves went ahead four days which was a lengthening of carbon fixation and therefore “the greenhouse effect caused by limited human “.
That amount has been used as a reference in climate models that calculate the accumulation of carbon dioxide in the atmosphere.
