When and how quickly can ecosystems ‘tip,’ and how will they develop in the future? Researchers from the University of Potsdam, the PIK, and the TU Munich have developed a new method to measure how close an ecosystem is to a catastrophic tipping point. www.nature.com/articles/s41...

The density of wood from trees and shrubs varies widely—not only between species, but also within them. Fischer et al. show, among other things, that plants growing in extreme environments have higher wood density than those elsewhere. nph.onlinelibrary.wiley.com/doi/10.1111/...

High Mountain Asia’s surface waters warmed from 1994–2023 (avg +0.1°C, up to +0.3°C), with faster warming in snow-covered areas and clear recent acceleration. Surface water is heating faster than nearby land, driven by rapid cryosphere changes. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Integrating mobile CRNS soil-moisture data into the mHM model greatly boosts its ability to capture spatial and temporal moisture patterns. Forests remain challenging, but results show strong gains and good transferability for better hydrological forecasts. www.frontiersin.org/journals/wat...

Extreme rain intensifies faster on warm days mainly because weather shifts from gentle to convective storms. Big systems become more convective above ~14 °C dew point, boosting short-burst rainfall and flood risk. rdcu.be/eTfHO

Do we do research, where it matters? Globally research on floods, droughts, and landslides is so biased that 100 times more people need to be affected in low-income countries before they receive a similar research attention than high-income countries agupubs.onlinelibrary.wiley.com/doi/10.1029/...

There is no need to use full landslide polygons in hazard models! We use topology & morphology to separate source & runout areas with <20% accuracy. DOI: doi.org/10.1016/j.en... Code: github.com/kushanavbhuy... Soon in #landsifier for easy use: pypi.org/project/land...
