Earth, home of human beings, is 70% water and 30% land which has nurtured splendid civilizations and flourishing lives. The cover story of this issue reflects the evolution of Earth by merging an unknown planet in a unified scene with different landscapes throughout the history such as glacier, desert, ocean, mountain, river and magma. The contrast between the past to reality can best illustrate our respect to our motherland. It is not only the subjects of geoscience studies, but also the common goal of all multidisciplinary research and the shared duties of mankind to understand, care and protect our planet to build a better future. |

Graphical abstract
The evolution of the Asian monsoon from the Late Oligocene to the Early Miocene is poorly understood. Here, we first reconstruct the precipitation data of central Tibet during 26每16 million years ago (Ma), applying the coexistence approach to sedimentary pollen data, and detect an intensified Asian monsoon with ‵1.35 Ma and ‵0.33 Ma cycles. Paleoclimate modeling is used to show the importance of paleogeographic location in the development of the paleomonsoon. In addition, the results of spectral analysis suggest that the fluctuations in the Asian monsoon during 26每16 Ma can be attributed to the long-period cyclicities in obliquity (‵1.2 Ma).
