Phanerozoic Global Temperature Curve

Abstract

The New and Improved Global Temperature Curve for the Last 540 Million Years. PETM= Paleocene-Eocene Thermal Maximum (55.8 Ma), EEOC = Early Eocene Climatic Optimum (54 Ma – 46 Ma), MECO = Mid-Eocene Climatic Optimum(42 Ma), EOT = Eocene-Oligocene Transition (40 Ma – 33 Ma), MMCO=Mid-Miocene Climatic Optimum (15Ma – 13Ma), LGM = Last Glacial Maximum (21,000 years ago), 2016 = Modern MAT, PAW = Post-Anthropogenic Warming . White stars indicate rapid cooling episodes (Stoll-Schrag Events26) at 160Ma, 127Ma, 97Ma, 91Ma, 71Ma, and 65 Ma). Black stars represent rapid warming episodes (Kidder-Worsley Events16) at (Present-day, 15Ma, 43Ma, 56Ma, 65Ma, 93Ma, 120Ma, 183Ma, 200Ma, 251Ma, 300Ma, 359Ma, 374Ma, 444Ma, 499Ma, 520Ma, and 542 Ma).

The Phanerozoic Eon has witnessed considerable changes in the climate system as well as abundant animals and plant life. Therefore, the evolution of the climate system in this Eon is worthy of extensive research. Only by studying climate changes in the past can we understand the driving mechanisms for climate changes in the future and make reliable climate projections. Apart from observational paleoclimate proxy datasets, climate simulations provide an alternative approach to investigate past climate conditions of the Earth, especially for long time span in the deep past. Here we perform 55 snapshot simulations for the past 540 million years, with a 10-million-year interval, using the Community Earth System Model version 1.2.2 (CESM1.2.2). The climate simulation dataset includes global distributions of monthly surface temperatures and precipitation, with a 1° horizontal resolution of 0.9° × 1.25° in latitude and longitude. This open access climate dataset is useful for multidisciplinary research, such as paleoclimate, geology, geochemistry, and paleontology.

Many Middle-Late Triassic (Ladinian-Carnian) global and local humid climate events that impacted on global palaeontological evolution and mineral distribution have been recorded in the rocks. The lacustrine sedimentary sequence of the Yanchang Formation in the Ordos Basin in the northeastern Tethys region may be an important example of control by global humid climate events. As revealed by an established chronostratigraphic framework and the study of organic carbon isotopes, elemental geochemistry and clay minerals, the Chang 7 Member of the Yanchang Formation was deposited in the Ladinian-Carnian, and the high total organic carbon (TOC) and total nitrogen (TN) contents indicate the high productivity of the ancient lake. The observed elemental ratios (Sr/Cu, Rb/Sr and Fe/Mn) and high contents of mixed-layer smectite indicate humid climate events in the Chang 7³ and Chang 7¹ members. The increases in weathering degree, surface temperature and terrigenous clastic material input indicate enhancement of the hydrological cycle driven by a warm-humid climate. The arid-wet transitions, the negative excursions of the studied organic carbon isotope and the temperature fluctuations during the deposition of the Chang 7³ and Chang 7¹ members of the Yanchang Formation are consistent with the Carnian humid event (CHE) and Ladinian-Carnian humid interval (L-CHI). The palaeontological diversity and the development of organic shales, turbidity currents and sandy debris flows in the Chang 7 Member may represent the continental sedimentary responses to coeval global humid climate events. The isochronous eruptions of volcanoes around the Ordos Basin may have intensified the global greenhouse effect and become an important factor driving the multi-stage humid climate events in the Ordos Basin.

Pencil-and-paper climate modelling is extracted from the comprehensive previous research on the inherently complex natural processes. A major goal is to mediate between general scientific knowledge and the wide-spread scepticism by identifying the driving forces, seeking simple descriptions, uncovering reproducibility, and thus contributing to transparency. The results of the shortcut model are in outstanding agreement with earlier measurement data and simulation studies. Two observations are fundamentally novel requiring scrutinization by the natural sciences community: (1) near-proportionality of atmospheric infrared absorption to particle densities and (2), temperature impact from human energy consumption. Independently, the presented framework allows for straightforward climate projections and risk assessment. As result, future economic growth is demanded to zero, even in a renewables (Green Growth) world.
