The two primary methods of investigating past climate are through proxy records (e.g. tree rings, ice cores, and corals) and climate models. These two methods have different strengths and weaknesses, and paleoclimate data assimilation is a method which aims to utilize the advantages of each to reconstruct past climate. Our new paper, published today in Climate of the Past (available here: https://www.clim-past.net/15/1251/2019/), explores this method and reconstructs multiple climate fields over the past 2000 years. Take a look.

New paper! Our paper, published today in Nature, studies the connection between the strength of the Northern Hemisphere latitudinal temperature gradient and mid-latitude net precipitation during the Holocene: https://www.nature.com/articles/s41586-019-1060-3. The primary finding is that a weaker temperature gradient in the early Holocene is associated with reduced net precipitation in the mid-latitudes, consistent with the idea of weaker mid-latitude cyclones. Because global climate change is currently weakening this temperature gradient through Arctic amplification, this paper is exceedingly relevant to the study of future changes. This paper is the result of diligent effort by scientists here at Northern Arizona University (Cody Routson, Nick McKay, Darrell Kaufman, and myself) as well as co-authors at other universities (Hugues Goosse, Bryan Shuman, Jessica Rodysill, and Toby Ault).
