Fossils are critical for understanding the environmental changes and uplift history of the Tibetan Plateau during the Cenozoic. As the largest inland basin located at the northeastern plateau, Qaidam Basin has been regarded as the key region to understand the climatic changes in the plateau during the Cenozoic. Herein, fossil legumes from the Oligo...
Article
Full-text available
As the largest inland basin in the northeastern Tibetan Plateau, Qaidam Basin has traditionally been thought of as the key region to study the Cenozoic climatic changes in the plateau; however, the information from a palaeobotanic respect is still lacking because of the paucity of the fossil plants. Fossil fruits and foliage of Ailanthus (Simarouba...

A better theoretical and practical understanding of the linkage between paleo-CO2 and climate during geological history is important to enhance the sustainable development of modern human society. Development in plant physiology since the 1980s has led to the realization that fossil plants can serve as a proxy for paleoatmosphere and paleobiosphere...

NECLIME is an open international network of scientists working on Cenozoic climate evolution and related changes of continental ecosystems. During the past 65 million years of Earth history, globally warmer-then-present conditions prevailed in a world with almost modern paleogeography. These timespans represent promising case studies for anticipated future scenarios. Within the NECLIME network, we aim to combine data on past climate change and its environmental impact for large-scale reconstructions. NECLIME research activities comprise paleoclimate reconstructions, including atmospheric CO₂ and ecosystem analysis using multiple quantitative methods on various primarily continental proxies (plants; vertebrates; invertebrates; geochemistry and geological proxies). Complementing model studies are employed to assess connections and processes driving ocean, atmosphere and biosphere at global and regional scales. NECLIME was established in 1999 with the aim to understand Neogene trends across Eurasia. This basic idea quickly and constantly expanded to a global interest and a wider stratigaphical frame. The steadily growing NECLIME network with currently around 140 members in 34 countries is coordinated by a team of researchers and an advisory board. NECLIME holds annual conferences and workshops and administers working groups bringing forward scientific exchange, joint projects, and the integration of research data.
