The Earth is flat for climate modelers

Did you know that? Modelers don’t stop surprising us!!!

If you find this hard to believe, read the paper by Michael J. Prather and Juno C. Hsu, from the University of California, which has recently been published in the Proceedings of the National Academy of Science USA.

See the reference and the significance statement below the flat Earth



Prather, M.J. & Hsu, J.C. 2019. A round earth for climate models. Proc. Natl. Acad. Sci. USA, 116: 19330-19335.


Early climate and weather models, constrained by computing resources, made numerical approximations on modeling the real world. One process, the radiative transfer of sunlight through the atmosphere, has always been a costly component. As computational ability expanded, these models added resolution, processes, and numerical methods to reduce errors and become the Earth system models that we use today. While many of the original approximations have since been improved, one—that the Earth’s surface and atmosphere are locally flat—remains in current models. Correcting from flat to spherical atmospheres leads to regionally differential solar heating at rates comparable to the climate forcing by greenhouse. gases and aerosols. In addition, spherical atmospheres change how we evaluate the aerosol direct radiative forcing.

The biodiversity and ecosystems of this lost world have been generated by purely natural ecological and evolutionary processes, which turns Pantepui into a natural laboratory to study the origin and evolution of Neotropical biomes. The following video provides an outlook of the Pantepui landscape.

The book is subdivided into four parts, namely (i) general aspects, (ii) the photosynthetic world, (iii) animal diversity and (iv) biodiversity conservation, and the following chapters:

  1. Definition and characterization of the Pantepui biogeographical province
  2. Climatic and ecological history of Pantepui and surrounding areas
  3. Pantepui as a dynamic biogeographical concept

Easter Island discovery: all options remain open

According to the current paradigm, the remote and enigmatic Easter Island, in the southeastern Pacific Ocean, is thought to have been discovered and settled by Polynesian sailors between about 800 and 1200 CE. However, recent studies using the latest genomic, anthropological and paleoecological techniques have revived constroversy about a potential Amerindian discovery before Polynesian settlement.

The whole story can be read in a recent revision published in the journal Quaternary, where all the existing hypotheses on Easter Island discovery and settlement are reviewed and evaluated in light of the existing archaeological, anthropological, historical and paleoecological evidence. The reference and the abstract of this review are provided at following.

Reference: Rull, V. 2019. Human Discovery and Settlement of the Remote Easter Island (SE Pacific). Quaternary 2, 15.

Abstract. The discovery and settlement of the tiny and remote Easter Island (Rapa Nui) has been a classical controversy for decades. Present-day aboriginal people and their culture are undoubtedly of Polynesian origin, but it has been debated whether Native Americans discovered the island before the Polynesian settlement. Until recently, the paradigm was that Easter Island was discovered and settled just once by Polynesians in their millennial-scale eastward migration across the Pacific. However, the evidence for cultivation and consumption of an American plant—the sweet potato (Ipomoea batatas)—on the island before the European contact (1722 CE), even prior to the Europe-America contact (1492 CE), revived controversy. This paper reviews the classical archaeological, ethnological and paleoecological literature on the subject and summarizes the information into four main hypotheses to explain the sweet potato enigma: the long-distance dispersal hypothesis, the back-and-forth hypothesis, the Heyerdahl hypothesis, and the newcomers hypothesis. These hypotheses are evaluated in light of the more recent evidence (last decade), including molecular DNA phylogeny and phylogeography of humans and associated plants and animals, physical anthropology (craniometry and dietary analysis), and new paleoecological findings. It is concluded that, with the available evidence, none of the former hypotheses may be rejected and, therefore, all possibilities remain open. For future work, it is recommended to use the multiple working hypotheses framework and the strong inference method of hypothesis testing, rather than the ruling theory approach, very common in Easter Island research.

Palynology and Vegetation History – new book

A new book has been published in the Frontiers Research Topic series entitled “Palynology and Vegetation History“, to commemorate the centenary of the first quantitative pollen diagram, produced by the Swedish geologist Lennart von Post, the founder of paleoecological palynology. The book has been edited by Valentí Rull (ICTJA-CSIC, Spain), Encarni Montoya (ICTA-CSIC, Spain), Thomas Giesecke (Georg-August Univ. Göttingen, Germany) and Jesse Morris (Univ. Utah, USA) and consists of 18 papers by 91 contributors from Africa, North and South America, Europe and Oceania.

The main aim of the book is to provide a thorough view of the use of palynology in aspects such as the reconstruction of Quaternary vegetation and environmental changes, the role of natural and anthropogenic drivers in the development of the Quaternary vegetation, the shaping of present-day ecological and biogeographical patterns, the potential application of this knowledge in biodiversity conservation and landscape restoration and the development of new methods of pollen analysis and data management. The Research Topic is subdivided into four main conceptual parts, namely (1) modern analog studies; (2) land cover estimates from pollen data; (3) vegetation dynamics reconstructions from Europe, North and South America, Africa and Oceania; and (4) large-scale reviews and meta-analyses. Hopefully, this Research Topic will serve to appraise the state of the art of modern palynology and highlight the usefulness of this discipline in long-term ecological research.
