Our research focuses on developing and analyzing high-resolution proxy records of past spatiotemporal climate and paleoenvironmental variability. We use proxy system and climate models and a diverse set of statistical techniques in order to further refine and enhance our understanding of past, present, and future climate and environmental changes. We specialize in dendroclimatology, multiproxy paleoclimatology, and climate field reconstructions.

- The School of Geography and Development has issued a statement of support and solidarity regarding racism and the murder of George Floyd.
- Congratulation to Julie and Talia, who defended their Masters theses in early May and now move onto the Ph.D. program here at Arizona - look for their research papers soon!
- In a new paper in PNAS, Justin Martin et al. (Kevin is a coauthor) show that the turn-of-the-century drought was the worst of the last millennium, caused by the impact of warming temperatures.
- How will drought change in the future under increasing CO2? Our new paper in Earth's Future led by Ben Cook looks at CMIP6 drought projections under different forcing scenarios
- Neil Pederson from Harvard Forest leads a new paper on the complexities in population-level vulnerability to climate change for Atlantic white cedar in the eastern United States.
- We've got an exciting new paper in GRL led by Feng Zhu on reconciling the reconstructed and modeled climate response to explosive volcanism during the Common Era.
- Kevin has a new paper out describing an interpreted language version of the Vaganov-Shashkin model and providing examples of its application in MATLAB
- Julie is the co-author of a new paper (Meko et al.) on the impact of high flows of an Arctic river on ring widths of floodplain trees in The Holocene
- Jessie has another new paper, this one in Journal of Geophysical Research, using a network of Atlantic white cedar trees to reconstruct northeastern United States climate in space and time over the last several centuries
- Jessie has an exciting new paper that builds a 2500 year chronology from Atlantic white cedar for the northeastern United States
- Talia's on the radio! Listen to her talk about her new study on the tenuous link between climate change and Central American migration on KJZZ!
- Talia leads an exciting new paper on trends in rainfall extremes and the Central American Midsummer Drought. She finds that interannual variability still dominates over long-term trends in most of the domain, including the origin regions for migrants and refugees arriving at the US border. UANews wrote a press release for the study - When Reporting Climate-Driven Human Migration, Place Matters
- Kevin leads a new paper in Geophysical Research Letters identifying the atmosphere and ocean circulation linking drought on either side of the Atlantic.
- Our new paper in Quaternary Science Reviews provides multiple lines of evidence that Ilopango volcano in El Salvador was the source of the colossal 540 CE eruption.
- We're excited to welcome Dr. Nick Gauthier to the Past Landscapes Lab as a new Postdoctoral Research Scientist!
- We've got a new paper in The Holocene on 'Improved dendroclimatic calibration using Blue Intensity for white spruce in the southern Yukon' led by Rob Wilson
- Congratulations to Dr. Jessie Pearl who successfully defended her Ph.D. dissertation - Reconstructing Late Holocene Climate and Coastal Evolution for the Northeastern United States - in May!
- Columbia University graduate student Mukund Rao leads a new paper describing a double bootstrapping procedure for evaluating the significance of superposed epoch analyses
- We have a new paper, led by Ed Cook, reconstructing the North Atlantic Oscillation (NAO) over the last millennium. We show that there is no persistent positive NAO during Medieval times, that that reconstruction is consistent with a stochastically forced process, and that climate models can simulate the spectra of this process.
- Laia Andreu-Hayles leads a tour-de-force paper describing the complete process for tree-ring isotope analysis developed at the Lamont-Doherty Earth Observatory.
- Kathy Allen leads a new paper in Climate Dynamics on 'Tree-ring reconstructions of cool season temperature for far southeastern Australia'
- Led by Andy Bunn, we've got a new paper in Geophysical Research Letters investigating the spatial and temporal variability in the climate response of bristlecone pines
- Congratulations to Dr. Gloria Jimenez, who successfully defended her dissertation, Reconstructing Tropical Pacific Climate Variability from Coral Archives on November 14th!
- Exciting news! Bethany Coulthard will be joining the Department of Geosciences at UNLV in January 2019 as a new Assistant Professor!
