| Summary: | The Eurasian forests are an important component in the earth’s climate system: Forests contain a lot of carbon in the vegetation and in the soil. But their role under warming conditions is still unclear – on the one hand, a higher CO 2 level in the air acts like a fertilizer for plants that grow and thus store more CO ">2 in the form of carbon. On the other hand, microbes that like warmer temperatures bring the soil to decompose faster and release even more CO ">2 and methane. To monitor long-term biogeochemical changes, a German-Russian research collaboration established an observatory in the Siberian taiga. Since 2006, the regional effects of global warming are studied from the Zotino Tall Tower Observatory. As MARTIN HEIMANN explains in this video, two of the main findings of the long-term measurements are that currently the western Siberian forests store more carbon than they release. However, due to the many bogs the region is also a source of methane, another important greenhouse gas. |
