Empirical and process-based approaches to climate-induced forest mortality models
Globally, forests store â¼45% of carbon sequestered terrestrially, contribute more to the terrestrial sink per area than any other land cover type, and assimilate an important...- publication PDF

The (in)visible health risks of climate change
This paper scrutinizes the assertion that knowledge gaps concerning health risks from climate change are unjust, and must be addressed, because they hinder evidence-led...- publication PDF

Understanding the limitations of gyrochronology for old field stars
Nearly half a century has passed since the initial indications that stellar rotation slows while chromospheric activity weakens with a power-law dependence on age, the so-called...- publication PDF
