Books

Tyler Volk has authored seven books, most recently, Quarks to Culture: How We Came to Be [1]

Quarks to Culture explores the rhythm within what Tyler Volk calls the "grand sequence," a series of levels of sizes and innovations building from elementary quanta to globalized human civilization. The key is "combogenesis," the building-up from combination and integration to produce new things with innovative relations. Themes unfold in how physics and chemistry led to biological evolution, and biological evolution to cultural evolution. Volk develops an inclusive natural philosophy that brings clarity to our place in the world, a roadmap for our minds." [2] Quarks to Culture was reviewed in Science in January 2018. [3]

His previous books include: CO2 Rising: The World’s Greatest Environmental Challenge, [4] What is Death?: A Scientist Looks at the Cycle of Life, [5] Gaia's Body: Toward a Physiology of Earth, [6] and Metapatterns: Across Space, Time, and Mind. [7]

Environmental studies and teaching

With Dale Jamieson, Christopher Schlottmann, and others, Volk helped plan and develop the interdisciplinary Environmental Studies Program launched at New York University in Fall 2007. In Fall 2014, Environmental Studies [8] became a department in NYU’s Faculty of Arts and Science. Volk was awarded NYU’s “Golden Dozen” teaching award for academic years 2003-2004 [9] and 2007-2008. [10] In academic year 2008-2009 Volk received an all-university Distinguished Teaching Award. [11]

Biosphere science

Volk works toward knowledge about life on a global scale; past, present, and future. His collaborative research contributed to understanding the biosphere, with "biosphere" defined as the integrated system of atmosphere, ocean, soil, and life. [12] Volk's modeling of the global carbon cycle quantified biological versus physical-chemical impacts on the distribution of carbon and other elements in world's oceans. [13] [14]

Throughout deep time, biological evolution has been as important as purely physical forcings in shaping Earth's thermal and chemical states. [15] For instance, the evolution of plankton with shells of calcium carbonate increased the steady-state level of atmospheric CO2 and therefore pushed Earth's climate toward additional greenhouse warmth. [16] The evolution of flowering plants (angiosperms) had the opposite effect, cooling the Earth by enhancing chemical weathering rates on the continents and thereby lowering the steady-state levels of CO2. [17]

Volk's work with colleague David Schwartzman showed that an overall “biotic enhancement of weathering,” including activities by ancient bacterial mats and crusts, cooled the Earth by 30 or more degrees C (best estimates) relative to the baseline of an abiotic Earth. [18] Without an initial downward forcing of global temperature by the microbes, certain proteins would not have had enough stability for higher forms of life to evolve, such as plants. [19]

At the American Geophysical Union's Chapman Conference on the Gaia Hypothesis (Valencia, Spain, 2000), Volk served on the program committee and his presentation was published in 2004, “Gaia is life in a wasteworld of by-products.” [20] Clarifying a distinctive version of the Gaia-biosphere, Volk introduced concepts such as “biochemical guilds,” by-products, and “cycling ratios” across several works. [21] He debated terms such as “regulation” and issues about the structure of “Gaia” with James Lovelock, Tim Lenton, and David Wilkinson. [22] [23] Volk also publicly debated Axel Kleidon on the role of entropy in the biosphere. [24]

NASA advanced life support

Working for NASA on futuristic space projects, Volk built math models for the cycling of elements in what were called "closed ecological life support systems" (CELSS). From 1986-1998, he was active in this research subfield of advanced life support, helping NASA plan the systems that might someday keep astronauts alive on the Moon and Mars. With colleague John Rummel, he developed some of the first computer models to connect the flows and chemical transformations of crop production, human metabolism, and waste processing. [25] [26] Volk then turned attention to the modeling of crop growth and development for enhanced productivity, collaborating with experimentalists at Utah State University and at NASA centers in Florida, Texas, and California, in particular publishing with crop physiologists Bruce Bugbee of Utah State University and Raymond Wheeler of Kennedy Space Center, [27] as well as with his Ph.D. students Francesco Tubiello and James Cavazonni.

<span class="mw-page-title-main">Physical geography</span> Study of processes and patterns in the natural environment

Physical geography is one of the three main branches of geography. Physical geography is the branch of natural science which deals with the processes and patterns in the natural environment such as the atmosphere, hydrosphere, biosphere, and geosphere. This focus is in contrast with the branch of human geography, which focuses on the built environment, and technical geography, which focuses on using, studying, and creating tools to obtain,analyze, interpret, and understand spatial information. The three branches have significant overlap, however.

<span class="mw-page-title-main">Carbon cycle</span> Natural processes of carbon exchange

The carbon cycle is that part of the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth. Other major biogeochemical cycles include the nitrogen cycle and the water cycle. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone. The carbon cycle comprises a sequence of events that are key to making Earth capable of sustaining life. It describes the movement of carbon as it is recycled and reused throughout the biosphere, as well as long-term processes of carbon sequestration (storage) to and release from carbon sinks.

<span class="mw-page-title-main">Climate variability and change</span> Change in the statistical distribution of climate elements for an extended period

Climate variability includes all the variations in the climate that last longer than individual weather events, whereas the term climate change only refers to those variations that persist for a longer period of time, typically decades or more. Climate change may refer to any time in Earth's history, but the term is now commonly used to describe contemporary climate change. Since the Industrial Revolution, the climate has increasingly been affected by human activities.

<span class="mw-page-title-main">Geomorphology</span> Scientific study of landforms

Geomorphology is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near Earth's surface. Geomorphologists seek to understand why landscapes look the way they do, to understand landform and terrain history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling. Geomorphologists work within disciplines such as physical geography, geology, geodesy, engineering geology, archaeology, climatology, and geotechnical engineering. This broad base of interests contributes to many research styles and interests within the field.

<span class="mw-page-title-main">Gaia hypothesis</span> Paradigm that living organisms interact with their surroundings in a self-regulating system

The Gaia hypothesis, also known as the Gaia theory, Gaia paradigm, or the Gaia principle, proposes that living organisms interact with their inorganic surroundings on Earth to form a synergistic and self-regulating, complex system that helps to maintain and perpetuate the conditions for life on the planet.

<span class="mw-page-title-main">Natural environment</span> Living and non-living things on Earth

The natural environment or natural world encompasses all living and non-living things occurring naturally, meaning in this case not artificial. The term is most often applied to Earth or some parts of Earth. This environment encompasses the interaction of all living species, climate, weather and natural resources that affect human survival and economic activity. The concept of the natural environment can be distinguished as components:

<span class="mw-page-title-main">Oxygen cycle</span> Biogeochemical cycle of oxygen

Oxygen cycle refers to the movement of oxygen through the atmosphere (air), biosphere (plants and animals) and the lithosphere (the Earth’s crust). The oxygen cycle demonstrates how free oxygen is made available in each of these regions, as well as how it is used. The oxygen cycle is the biogeochemical cycle of oxygen atoms between different oxidation states in ions, oxides, and molecules through redox reactions within and between the spheres/reservoirs of the planet Earth. The word oxygen in the literature typically refers to the most common oxygen allotrope, elemental/diatomic oxygen (O2), as it is a common product or reactant of many biogeochemical redox reactions within the cycle. Processes within the oxygen cycle are considered to be biological or geological and are evaluated as either a source (O2 production) or sink (O2 consumption).

<span class="mw-page-title-main">Biogeochemistry</span> Study of chemical cycles of the earth that are either driven by or influence biological activity

Biogeochemistry is the scientific discipline that involves the study of the chemical, physical, geological, and biological processes and reactions that govern the composition of the natural environment. In particular, biogeochemistry is the study of biogeochemical cycles, the cycles of chemical elements such as carbon and nitrogen, and their interactions with and incorporation into living things transported through earth scale biological systems in space and time. The field focuses on chemical cycles which are either driven by or influence biological activity. Particular emphasis is placed on the study of carbon, nitrogen, sulfur, iron, and phosphorus cycles. Biogeochemistry is a systems science closely related to systems ecology.

<span class="mw-page-title-main">Carbonate–silicate cycle</span> Geochemical transformation of silicate rocks

The carbonate–silicate geochemical cycle, also known as the inorganic carbon cycle, describes the long-term transformation of silicate rocks to carbonate rocks by weathering and sedimentation, and the transformation of carbonate rocks back into silicate rocks by metamorphism and volcanism. Carbon dioxide is removed from the atmosphere during burial of weathered minerals and returned to the atmosphere through volcanism. On million-year time scales, the carbonate-silicate cycle is a key factor in controlling Earth's climate because it regulates carbon dioxide levels and therefore global temperature.

<span class="mw-page-title-main">Earth system science</span> Scientific study of the Earths spheres and their natural integrated systems

Earth system science (ESS) is the application of systems science to the Earth. In particular, it considers interactions and 'feedbacks', through material and energy fluxes, between the Earth's sub-systems' cycles, processes and "spheres"—atmosphere, hydrosphere, cryosphere, geosphere, pedosphere, lithosphere, biosphere, and even the magnetosphere—as well as the impact of human societies on these components. At its broadest scale, Earth system science brings together researchers across both the natural and social sciences, from fields including ecology, economics, geography, geology, glaciology, meteorology, oceanography, climatology, paleontology, sociology, and space science. Like the broader subject of systems science, Earth system science assumes a holistic view of the dynamic interaction between the Earth's spheres and their many constituent subsystems fluxes and processes, the resulting spatial organization and time evolution of these systems, and their variability, stability and instability. Subsets of Earth System science include systems geology and systems ecology, and many aspects of Earth System science are fundamental to the subjects of physical geography and climate science.

<span class="mw-page-title-main">Future of Earth</span> Long-term extrapolated geological and biological changes of Planet Earth

The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth's surface, the cooling rate of the planet's interior, the gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity. An uncertain factor is the pervasive influence of technology introduced by humans, such as climate engineering, which could cause significant changes to the planet. For example, the current Holocene extinction is being caused by technology, and the effects may last for up to five million years. In turn, technology may result in the extinction of humanity, leaving the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes.

<span class="mw-page-title-main">Planetary boundaries</span> Limits not to be exceeded if humanity wants to survive in a safe ecosystem

Planetary boundaries are a framework to describe limits to the impacts of human activities on the Earth system. Beyond these limits, the environment may not be able to self-regulate anymore. This would mean the Earth system would leave the period of stability of the Holocene, in which human society developed. Crossing a planetary boundary comes at the risk of abrupt environmental change. The framework is based on scientific evidence that human actions, especially those of industrialized societies since the Industrial Revolution, have become the main driver of global environmental change. According to the framework, "transgressing one or more planetary boundaries may be deleterious or even catastrophic due to the risk of crossing thresholds that will trigger non-linear, abrupt environmental change within continental-scale to planetary-scale systems."

The Deep Carbon Observatory (DCO) is a global research program designed to transform understanding of carbon's role in Earth. DCO is a community of scientists, including biologists, physicists, geoscientists and chemists, whose work crosses several traditional disciplinary lines to develop the new, integrative field of deep carbon science. To complement this research, the DCO's infrastructure includes public engagement and education, online and offline community support, innovative data management, and novel instrumentation development.
