A study in Nature Climate Change quantifies the potential for extreme heat events in Europe to generate mass mortality and projects tens of thousands of excess deaths. go.nature.com/483zJc3 🧪
This is figure 2, which shows temperature–mortality relationship across Europe.

What are the most exciting trends you’re seeing in spatial data science lately?
Some of mine:

- New file formats (e.g. #GeoParquet)
- Geospatial DBs (e.g. #DuckDB + spatial)
- Global discrete grids

What would you add?

#Geospatial #GISchat #RSpatial #GeoPython
A discrete global grid (DGG) is a mosaic that covers the entire Earth’s surface. Mathematically it is a space partitioning.

🌳💧📊 #PhDAlert! MSc in #ForestEcology or #EnvironmentalSciences? Excellent analytical and statistical skills in time-series analysis and experience with #treering methods🪵? We offer a #PhD position in #Dendroecology: apply.refline.ch/273855/1795/... #dendrosciences #ecology #ScienceJobs
Job offer: PhD in Dendroecology (f/m/d) You will be part of a project aiming to empirically disentangle atmospheric vs. soil drought impacts on intra- and inter-annual wood formation, and mechanistically model drought constraints on intra- and inter-annual tree growth dynamics (https://www.wsl.ch/en/projects/sad-tree) based on a unique monitoring network of 44 forest sites in Switzerland spanning 10 years of soil moisture and atmospheric climate data. In this context, you will contribute to the establishment and analysis of intra- and inter-annual time series of tree growth based on dendrometer, tree rings, and quantitative wood anatomy (QWA). You will be responsible for establishing improved empirical relationships of tree growth-environment interactions based on the long-term integrative Soil-Plant-Atmosphere-Continuum dataset (tree & stand traits, physical environment), analyzing: intra-annual water- and growth-related stem radius changes from dendrometer measurements, early-season wood anatomy related to water transport and rehydration, and long-term drought effects on growth using tree-ring widths. You have a Master's degree in forest ecology, environmental sciences, or equivalent. You should have excellent analytical and statistical skills in time-series analysis, preferably in dendrosciences and/or tree physiology. Ideally, you are proficient in programming and handling of large datasets, and have experience with tree-ring methods. You are able to efficiently expand and acquire knowledge in topics relevant to the project. You have a proficient command of written and spoken English, are able to work in a structured, efficient and independent manner, and have a high level of team spirit and have good communication skills.

Charting human migration over deep time

(via outofedenwalk.nationalgeographic.org/media/2013-0...)
A map titled "A WALK THROUGH TIME" showing human migration patterns from Africa across the globe over 200,000 years. The route is color-coded in rainbow bands from red (oldest, 200-60 thousand years ago) through yellow, green, blue, to pink (most recent, 15-10 thousand years ago). A white line traces the 21,000-mile walking route from East Africa ("Start") to South America ("Finish"). The map uses Fuller projection to straighten the circumglobal route.
