ABSTRACT

A direct consequence of rising CO2 is increasingly devastating flooding, because deciduous plants deploy fewer stomates each year as the atmospheric CO2 supplies more carbon for photosynthesis. When plants tran- spire less, more water runs off in streams and floods. Here we quantify this effect with high- resolution observations of changing density and size of stomates of a mesic tree, Ginkgo, since 1754. The observed decline in maximum potential transpiration corresponds with rising water levels in the Mississippi River and represents a potential transpiration decline from 1829 to 2015 of 18 mL s–1 m–2: a reduction of 29%. Rising atmospheric CO2 and declining transpiration promote flooding, which handicaps lowland cultivation and ren- ders irrelevant insurance and zoning concepts such as the 100-year flood.

INTRODUCTION Ongoing climatic change with rising atmospheric greenhouse gases (Yan et al., 2016) is disproportionally affecting tropical regions with sterilizing heat waves (Mora et al., 2017) and polar regions with disappearing sea ice (Kwok, 2018), but is less apparent in the American Midwest, thus allowing skepticism of global warming science (Wallace et al., 2014). Nevertheless, Midwestern cities and

4 GSA Today | October 2020 agriculture have been progressively ravaged by flooding (Fosu et al., 2018). Steadily increased floods and general level (U.S. Army Corps of Engineers, 2019) of the Mississippi River (Fig. 1A) have been independent of local climatic changes in precipitation and temperature (National Oceanographic and Atmospheric Administration, 2019a), which have remained surprisingly flat (Fig. 1B). Nor can increases in farmed areas be blamed for rising flood levels, because Midwestern culti- vated acreage reached a plateau between 1900 and 1960 (Clausen, 1979; Sohl et al., 2016; Andersen et al., 1996; U.S. Department of Agriculture Statistics Service, 2019), and has declined slightly since then (Fig. 1C). Flooding is a long-term and direct response to rising atmospheric CO2 concentrations of much greater consequence in mid-latitudes than temperature increases, and it has been observed for decades.

Deciduous trees adapt to rising CO2 annually by developing fewer stomates on spring leaves, because adequate CO2 for photosynthesis can be obtained by reduced air intake (Sugano et al., 2010; Chater et al., 2015). Fewer stomates also reduce plant transpiration of water, so that more precipitation runs off in rivers and floods (Betts et al.,

2007). The relationship between CO2 and stomatal density has been known for some time (Woodward, 1987), and there have been many attempts at quantifying the relationship (Royer et al., 2001; Retallack, 2001, 2009; Barclay and Wing, 2016; McElwain and Steinthorsdottir, 2017). Here we update quantification of stomatal response to Figure 2. Stomates from leaves of Ginkgo picked in 1754 from Deshima, Japan. Large atmospheric CO inferred from herbarium images with ~600 stomates and also non-stomatiferous areas below veins were counted 2 to ascertain total leaf conductance.

Such studies have been the direct gene expression for stomatal density We used scanning electron microscopy basis for determining CO2 levels from the in the developing leaf for that year (Sugano (SEM) images from herbarium specimens of distribution of stomates on fossil leaves et al., 2010; Chater et al., 2015).

A single collection of fossil or has been a favorite for such studies because Herbarium picked in Deshima, Japan, and herbarium leaves determines global CO2 of its unusually long fossil record, and so forward with specimens picked during the concentration with a resolution of weeks has the highest quality data (Barclay and dramatic upswing in CO2 over the past because the atmosphere is well mixed on Wing, 2016; Retallack and Conde, 2020). decade (Fig. 2).

Concentrations of atmospheric CO2 are response (Fig. 3B–3C). Counting smaller areas of cuticle with only

Stomatal bands are distinct from astomatic areas below veins, but we counted both stomatal and subvenal areas to capture total leaf conductance (Fig. 2B).

The current stomatal index CO2 paleoba- rometer (Retallack and Conde, 2020) is

based on atmospheric CO2 (C in ppm) from observations (National Oceanographic and Atmospheric Administration, 2019b) and ice cores (Lüthi et al., 2008) together with stomatal index (I in % from Equation 1) from microscopic imaging of herbarium speci-

mens in which number of stomates (ns) and

number of epidermal cells (ne) in the same area are counted. This inverse relationship (Equation 2) has an algebraically simplified equivalent (Equation 3) between Gingko sto-

matal index (I in %) and atmospheric CO2 s (C in ppm). Standard deviations (1 ) of CO2 concentration (in ppm) were calculated by Gaussian error propagation. Maximum –2 –1 potential transpiration (gwmax in mol·m s ) can be calculated using Equation 4 (Wolfram Alpha, 2019; Franks et al., 2014) with additional measurements of stomatal pore length (l, in m), width (w, in m), and density of stomates (D, as number per m2), as well as physical constants (Cussler, 1997) of diffusivity of water vapor in air (d = 0.0000282 m–2·s–1) and molar volume of air (v = 0.0224 m–3·mol–1), and 0.6 area correction factor for Ginkgo biloba stomatal anatomy (Franks et al., 2014). Diffusivity and molar volumes of vapor and liquid are all at 25 °C and 1 atm. All measurements of Ginkgo biloba stomatal density, length, and width are included in the GSA supplemental material.1 n I 100 s (1) nnse

Measures of stomatal length and width can be used to calculate maximum pore area and volume (Franks et al., 2014) and infer water conductance from leaves using the physics of diffusion through pores (Cussler, 1997). Our records show a secular decline in stomatal index, or percent stomates versus epidermal cells (Equation 1), of Ginkgo with increasing atmospheric CO2 as measured since 1955 on Mauna Loa (National Oceanographic and Atmospheric Organization, 2019b) with a base line provided by earlier data (Lüthi et al., 2008) from ice cores (Fig. 3A). The change in Ginkgo stomatal index over the past 265 years was due more to changes in stomatal density (Fig. 3B) than to stomatal size (Fig. 3C), and our high-precision data from Ginkgo are supported by less-accurate data from Quercus (Lammertsma et al., 2011). There is evidence from fossils that stomatal size also changes when atmospheric CO2 is very high (Retallack, 2009; Franks and Beerling, 2009), but that threshold was not reached in our observations. Stomatal size also changes significantly with gene ploidy levels (McElwain and Steinthorsdottir, 2017), but such jumps were not seen in our data either. The decline in transpiration for Ginkgo 1829–2015 has been dramatic (Fig. 4A): 0.98 mol s–1 m–2. This is 73 L s–1 m–2 of water vapor, or 18 mL s–1 m–2 liquid water, and a reduction by 29%. This substantial decline is a maximal value realized for only a part of the day in Figure 4. Changes in Ginkgo transpiration since 1754: (A) reduction in maximum stomatal favorable seasons and illumination, but if transpiration (l·s–1·m–2) of Ginkgo (1σ error) calculated using Equation 4; (B) mean annual level of Mississippi River at Hannibal, Missouri, (m) as a function of maximum stomatal tran- biorhythms of the plants remained compara- spiration (l·s–1·m–2) of Ginkgo.

GSA SECTION MEETINGS GSA Section Meetings are unique venues for interdisciplinary science and are an important hub for discussing and presenting current research. They provide an excellent opportunity for both professionals and students to attend and participate in technical sessions, field trips, and short courses close to home. In 2020, GSA was able to successfully run the South-Central Section Meeting in-person in Fort Worth, Texas, USA, on 9–10 March 2020, with over 300 attendees.

Tour Canada with Free Resources from the GSA Store To coincide with GSA 2020 Connects Online, we’re bringing the geology of Canada to you with a selection of volumes, transects, and field guides.

The field guide volume includes four guides from eastern Canada. Here you’ll examine glacial stratigraphy near Lac St. Pierre, explore the 277-foot-high Montmorency Falls (higher than Niagara Falls!), and trace the geologic evolution of the Thetford Mines ophiolite.

To begin your exploration, visit the GSA Store at https://rock.geosociety.org/Store/ and search “FreeMontreal”—we’ve gathered for you a large selection of classic Canadian volumes from the Decade of North American Geology collection. Get free digital access to them all now through the end of November.

Radiocarbon Dating Consistent Accuracy, Delivered on Time Mike Sharer MSAG `20—expected

Advance your career with a master’s degree in applied geosciences

Whether you’re an experienced geoscientist or are preparing to enter the field, Penn’s rigorous Master of Science in Applied Geosciences (MSAG) is a highly practical program that helps you take your next step. With a faculty of leading experts and courses designed to accelerate professional licensure, we know what you need to move forward in your career.

During his first year of the program, Mike Sharer (MSAG `20—expected) landed a full-time position as an environmental scientist at an engineering company. “The flexibility of being able to take classes at night has been huge. It allows me and other students who are working to apply what we learn in class on the job, and bring insights from the field into the classroom,” Mike says. He also appreciates that MSAG professors have industry experience and understand the challenges of balancing school with the unpredictable hours of fieldwork. “They go out of their way to help you succeed. It’s an incredible environment to be in,” Mike says.
