New paper: a radically simple theory for soil moisture, that explains much of the large-scale spatial and temporal variability relevant to climate. Surprisingly, VPD and plant physiology are not very important for understanding changes with warming.

New paper: painting neighborhoods white is one way to offset warming from climate change. But, we show that doing this perversely causes temperatures to INCREASE in surrounding neighborhoods, due to unintended impacts on rainfall. This increases heat inequality.

I'm giving a virtual talk today (November 18) at 2 pm ET. All welcome. It's on a simple theory for near-surface relative humidity over land. Among other things, the theory has major implications for projected changes in aridity with warming.

New paper: Why is relative humidity high in some places, and low in others? Surprisingly, there is no simple answer to this question, at least for the part of the atmosphere that we live in (near the land surface). We provide one.
