Is this planet growing warmer and warmer? What climatic change will occur in the future? To answer these big questions, however, the scien- tific community has to know first what happened in the geological his- tory of the Earth, namely, the paleoclimatic change. With his half-century- long research on loess deposition in China, Prof. Liu Dongsheng from the CAS Institute of Geology and Geophysics has unveiled an imposing paleoclimatic scenario happening in the Quaternary period; and more importantly, the work conducted by him and his colleagues and stu- dents has presented loess sediments in China as a complete and reli- able databank of paleoclimatic change.
