Hakone, Kanagawa-ken 247-0007, Japan Received: 24 September 2018; Accepted: 19 November 2018; Published: 26 November 2018 Abstract: Earth’s land surface is raised from conventionally flat 15 Gha to >64 Gha accounting for hilly slope undulation and topsoil relief detail. Three main aspects are: topography, rugosity/tortuosity, and micro-relief/porosity of ice/vegetation-free ground. Recalibration arises from four approaches: First, direct empirical estimates of compiled satellite/LiDAR data means of +2.5–26% surface progressively overlain by +94% at cm2 scale for soil ruggedness then +108% for mm2 micro-relief; Second, from digital elevation models with thrice 1.6–2.0 times flat areas; Third, by ‘reverse engineering’ global soil bulk densities and carbon reserves requiring ×4–6 land. Finally, a Fermi estimation doubles the Earth’s surface—as exposed to Sun, air and rain—conveniently set at 100 Gha (with 64 Gha land:36 Gha ocean). Soil organic carbon (SOC) thereby grows to 8580 Gt mainly in SOM-humus with its biotic complexity plus roots, Vesicular-Arbuscular Mycorrhiza (VAM-fungi), leaf-litter and earthworms itself totaling 17,810 Gt. Although four to six times IPCC’s or NASA/NOAA’s calculated 1500–2300 Gt SOC, this is likely an underestimation. Global biomass and biodiversity are at least doubled (×2–3.5) and net primary productivity (NPP) increases to >270 Gt C yr−1 due to terrain. Rationale for a ‘Soil Ecology Institute’ gains ground. Keywords: topographical land surface-area; soil carbon sequestration; global climate; earthworms 1. Introduction This paper attempts to answer the simple question: “What’s the Earth’s true surface area?”. Surprisingly, this has no exact answer yet is key for determining the extent of the living world and it is crucial for understanding our planet’s essential life-support systems, especially the neglected soil. Even the most basic information on soils—upon which we live and depend for >99% human food [1–3], 100% timber and natural fibres, to filter all our drinking water, for medicines, such as Penicillins, Streptomycins, Malacidins and now Teixobactin or drugs, like Ivermectin (anti-parasitic) and Bleomycin (anti-cancer), and which support >98% of biota [4–6] (and herein) whilst also buffering pollution and climate change—is poorly known. For example: How much topsoil is there? What is its rate of production and loss? How about total soil biodiversity, primary productivity, and the principal vulnerabilities or extinction threats? Part of the reason for knowledge deficit is the lack of a single ‘Soil Ecology Institute’ comparable to myriad Marine, Aquatic, Atmospheric and Astronomical advocacy or research facilities around the globe (plus innumerable agriculture, chemistry, microbiology, or physics laboratories, albeit some claim a soil remit). A major oversight is ignoring terrain and topsoil, the main issue the current work confronts, as this graphic summarizes (Figure1).
