Global Relationships between Cropland Intensification and Summer Temperature Extremes over the Last 50 Years
Mueller, Nathaniel; Rhines, Andrew; Butler, Ethan; Ray, Deepak; Siebert, Stefan; Holbrook, Noel; Huybers, Peter (American Meteorological Society, 2017-09)Conversion of native ecosystems to cropland and the use of irrigation are considered dominant pathways through which agricultural land-use change alters regional climate. Recent research proposes that increases in cropland ... -
Global Surface Temperature Response to 11-Yr Solar Cycle Forcing Consistent with General Circulation Model Results
Amdur, Ted; Stine, Alexander; Huybers, Peter (American Meteorological Society, 2021-04)The 11-year solar-cycle is associated with a roughly 1 W m-2 trough-to-peak variation in total solar irradiance and is expected to produce a global temperature response. The amplitude of this response is, however, ... -
Heterogeneous warming of Northern Hemisphere surface temperatures over the last 1200 years
Tingley, Martin; Huybers, Peter John (Wiley-Blackwell, 2015)The relationship between the mean and spatial variability of Northern Hemisphere surface temperature anomalies over the last 1200 years is examined using instrumental and proxy records. Nonparametric statistical tests ... -
How is the ocean filled?
Gebbie, Geoffrey; Huybers, Peter John (Wiley-Blackwell, 2011)The ocean surface rapidly exchanges heat, freshwater, and gases with the atmosphere, but once water sinks into the ocean interior, the inherited properties of seawater are closely conserved. Previous water-mass decompositions ... -
Hydrothermal Deposition on the Juan De Fuca Ridge Over Multiple Glacial–interglacial Cycles
Costa, Kassandra; McManus, Jerry; Middleton, Jennifer; Langmuir, Charles; Huybers, Peter; Winckler, Gisela; Mukhopadhyay, Sujoy (Elsevier BV, 2017-12)Hydrothermal systems play an important role in modern marine chemistry, but little is known about how they may have varied on 100,000 year timescales. Here we present high-resolution records of non-lithogenic metal fluxes ... -
Identification and interpretation of nonnormality in atmospheric time series
Proistosescu, Cristian; Rhines, Andrew Nelson; Huybers, Peter John (Wiley-Blackwell, 2016)Nonnormal characteristics of geophysical time series are important determinants of extreme events and may provide insight into the underlying dynamics of a system. The structure of nonnormality in winter temperature is ... -
Impacts of elevated atmospheric CO2 on nutrient content of important food crops
Dietterich, Lee H.; Zanobetti, Antonella; Kloog, Itai; Huybers, Peter; Leakey, Andrew D. B.; Bloom, Arnold J.; Carlisle, Eli; Fernando, Nimesha; Fitzgerald, Glenn; Hasegawa, Toshihiro; Holbrook, N. Michele; Nelson, Randall L.; Norton, Robert; Ottman, Michael J.; Raboy, Victor; Sakai, Hidemitsu; Sartor, Karla A.; Schwartz, Joel; Seneweera, Saman; Usui, Yasuhiro; Yoshinaga, Satoshi; Myers, Samuel S. (Nature Publishing Group, 2015)One of the many ways that climate change may affect human health is by altering the nutrient content of food crops. However, previous attempts to study the effects of increased atmospheric CO2 on crop nutrition have been ... -
Implications of Liebig’s Law of the Minimum for Tree-Ring Reconstructions of Climate
Stine, Alexander; Huybers, Peter (IOP Publishing, 2017-11-01)A basic principle of ecology, known as Liebig's Law of the Minimum, is that plant growth reflects the strongest limiting environmental factor. This principle implies that a limiting environmental factor can be inferred ... -
Imprints of Geodynamic Processes on the Paleoclimate Record
Austermann, Jacqueline (2016-05-18)In this thesis I investigate how solid Earth deformation associated with glacial isostatic adjustment and mantle convection impacted ice age climate. In particular, I discard approximations that treat the Earth's internal ... -
Increasing CO2 threatens human nutrition
Myers, Zanobetti; Huybers, Peter John (Nature Publishing Group, 2014)Dietary deficiencies of zinc and iron are a substantial global public health problem. An estimated two billion people suffer these deficiencies1, causing a loss of 63 million life-years annually2, 3. Most of these people ... -
The Influence of True Polar Wander on Glacial Inception in North America
Daradich, A; Huybers, Peter; Mitrovica, Jerry; Chan, N; Austermann, J (Elsevier BV, 2017-03)The impact that long-term changes in Earth's rotation axis relative to the surface geography, or true polar wander (TPW), and continental drift have had in driving cooling of high-latitude North America since the Eocene ... -
Integrated Summer Insolation Forcing and 40,000-Year Glacial Cycles: The Perspective from an Ice-Sheet/Energy-Balance Model
Huybers, Peter John; Tziperman, Eli (American Geophysical Union, 2008)Although the origins of the 40,000-year glacial cycles during the early Pleistocene are readily attributed to changes in Earth's obliquity (also having a 40,000-year period), the lack of ice-volume variability at precession ... -
Integrated Summer Insolation Forcing and 40,000-Year Glacial Cycles: The Perspective from an Ice-Sheet/Energy-Balance Model
Huybers, Peter; Tziperman, Eli (American Geophysical Union, 2008)Although the origins of the 40,000-year glacial cycles during the early Pleistocene are readily attributed to changes in Earth's obliquity (also having a 40,000-year period), the lack of ice-volume variability at precession ... -
Is There an Orbital Signal in the Polar Layered Deposits on Mars?
Perron, J. Taylor; Huybers, Peter John (Geological Society of America, 2009)Do the polar layered deposits on Mars reflect orbital control or stochastic variability? It is first useful to determine whether an orbital signal would be detected, even if present. An estimate of the uncertainty in the ... -
Links Between Annual, Milankovitch and Continuum Temperature Variability
Huybers, Peter John; Curry, William Thomas (Nature Publishing Group, 2006)Climate variability exists at all timescales—and climatic processes are intimately coupled, so that understanding variability at any one timescale requires some understanding of the whole. Records of the Earth's surface ... -
Localization of mountain glacier termini in Landsat multi-spectral images
Kachouie, Nezamoddin N.; Huybers, Peter John; Schwartzman, Armin (Elsevier BV, 2013)This paper addresses the quantification of glacier retreat through remote sensing. Specifically, we use multi-spectral Landsat satellite images for the estimation of glacier termini locations. Different frequency bands—including ... -
Long-lead predictions of eastern United States hot days from Pacific sea surface temperatures
McKinnon, Karen Aline; Rhines, Andrew Nelson; Tingley, M; Huybers, Peter John (Nature Publishing Group, 2016)Seasonal forecast models exhibit only modest skill in predicting extreme summer temperatures across the eastern US. Anomalies in sea surface temperature and monthly-resolution rainfall have, however, been correlated with ... -
Making sense of palaeoclimate sensitivity
Rohling, E.; Huybers, Peter John (Nature Publishing Group, 2012)Many palaeoclimate studies have quantified pre-anthropogenic climate change to calculate climate sensitivity (equilibrium temperature change in response to radiative forcing change), but a lack of consistent methodologies ... -
Mapping and Characterizing the Alaskan North Slope Methane Flux With Airborne Eddy-Covariance Flux Measurements
Healy, Claire Ellen (2016-09-08)Understanding and forecasting the progression of climate change imposes new observational challenges that require broadening of both spatial and temporal coverage as well as resolution. Technological advances in molecular ... -
The Mean Age of Ocean Waters Inferred from Radiocarbon Observations: Sensitivity to Surface Sources and Accounting for Mixing Histories
Gebbie, Geoffrey; Huybers, Peter John (American Meteorological Society, 2012)A number of previous observational studies have found that the waters of the deep Pacific Ocean have an age, or elapsed time since contact with the surface, of 700–1000 yr. Numerical models suggest ages twice as old. Here, ...
