[My sincere thoughts to those on those the Nepal/Tibet border so very effected by the recent GLOF-style flooding; the loss of your family and friends – and ‘things’ – must be so very hard!
May the missing individuals return safely. 🙏]

“What happens when communities face 'too much water' during the monsoon and 'too little water' during the dry season? [Their] research in Dudhauli and Siraha municipalities [Nepal] shows that floods and droughts are not merely environmental challenges; rather, they interact with existing inequalities and vulnerabilities, intensifying conflicts over water and land resources.
From upstream-downstream tensions following flood damage and changing water flows to competition over wells and handpumps during periods of scarcity, the findings show that hydro-climatic extremes often act as amplifiers of existing social, economic, and political vulnerabilities.
The study underscores the importance of moving beyond managing climatic hazards alone towards conflict-sensitive and equitable water governance that addresses structural inequalities, strengthens local adaptive capacities, and supports fair water allocation and conflict resolution…”

“Are global river flows no longer natural? Can we really talk about natural rivers? [The authors] started asking ourselves these questions a few years ago over wonderful discussion sessions.
[They] argue that global river systems have entered a new phase, one of Anthropogenic River Flows, where flow regimes arise from the persistent interaction of:
• the physical alteration of river systems,
• the institutional and socio-technical organisation of water use and allocation
• broader global and systemic processes operating across scales.
In the Anthropocene, these domains do not operate independently because a change in one alters how the other two function. Global water risks and river flow properties then become an emergent property of these interactions.
As a result, [the authors] call for a rethinking of how we study, understand, and manage river flows to better reflect this new reality…”

“💧 With drought [and high temperatures] gripping many areas of the world right now... [the H/T] wanted to highlight a new paper in PLOS Water this week with a very timely focus on hydroclimatic stresses and what can be done to mitigate this through water management practices when it comes to agriculture.
[The authors] investigate[d] adaptive water management practices in California’s Santa Clara Valley via remote sensing and machine learning techniques. They [found] good evidence for use of customized agricultural water-management plans for irrigation monitoring, conservation planning, and adaptive water management in groundwater-dependent regions such as is found in California…”

H/T @Daniel Swain
“Hydroclimate volatility refers to sudden, large and/or frequent transitions between very dry and very wet conditions. In this Review, we examine how hydroclimate volatility is anticipated to evolve with anthropogenic warming. Using a metric of ‘hydroclimate whiplash’ based on the Standardized Precipitation Evapotranspiration Index, global-averaged subseasonal (3-month) and interannual (12-month) whiplash have increased by 31–66% and 8–31%, respectively, since the mid-twentieth century. Further increases are anticipated with ongoing warming, including subseasonal increases of 113% and interannual increases of 52% over land areas with 3 °C of warming; these changes are largest at high latitudes and from northern Africa eastward into South Asia. Extensive evidence links these increases primarily to thermodynamics, namely the rising water-vapour-holding capacity and potential evaporative demand of the atmosphere. Increases in hydroclimate volatility will amplify hazards associated with rapid swings between wet and dry states (including flash floods, wildfires, landslides and disease outbreaks), and could accelerate a water management shift towards co-management of drought and flood risks. A clearer understanding of plausible future trajectories of hydroclimate volatility requires expanded focus on the response of atmospheric circulation to regional and global forcings, as well as land–ocean–atmosphere feedbacks, using large ensemble climate model simulations, storm-resolving high-resolution models and emerging machine learning methods…

H/T @DanielSwain
"The success of the climatologist Daniel Swain rests on a simple foundation: His specialty has long been how global climate change messes with local weather. Many climatologists focus on subjects that seem arcane: mean global temperatures registered in Celsius, radiative forcing, the reflectivity of clouds. Swain, in contrast, talks in plain English—constantly, really, in interviews with CBS, NBC, the Weather Channel, and The Washington Post, as well as on his own blog and YouTube channel, Weather West—about the wind and the rain and the temperature outside, and how they are influenced by the larger forces of the atmosphere.
“He uses language that is both precise and deep but very accessible, and that’s why you see him quoted everywhere,” Mark Hertsgaard, a longtime climate journalist who is the executive director of Covering Climate Now, told [the Atlantic]. According to Swain’s own tally, he does more than 200 media interviews a year; he is, in other words, about as omnipresent as a weather guy can be in people’s lives. A climate scientist at the University of California Agriculture and Natural Resources’ research unit, Swain is not exactly a “weather influencer,” that breed of streamer who delivers breathless updates about the next big storm. But he has become one of the country’s most influential explainers of the weather’s relationship to the climate; you’ve almost certainly heard from him if you consume just a scintilla of climate-related news…”

Thrilled to have been included on this paper led by Niamh Cahill. We propose a #Bayesian time series model for catchment scale #hydroclimate reconstructions. The paper makes use of the Palaeowise database of Australasian #climate proxy data (the first paper to use the database 🙌) https://onlinelibrary.wiley.com/doi/10.1002/env.2786

I'm very happy that this paper that Ulf Büntgen and I wrote together has finally come out. Using annually resolved #hydroclimate data we found that central Europe experienced increasingly dry summers from the 420 to the 450s CE (and beyond). This coincided with some of the most devastating raids by #Huns on #Roman territory. We argue that Huns used raiding as a buffering strategy to mitigate against dry summers which made it harder for them to pasture their herds. https://www.cam.ac.uk/research/news/drought-encouraged-attilas-huns-to-attack-the-roman-empire-tree-rings-suggest
