    “The present study assesses the impacts of climate change on blue and green water in the Kessie Watershed of the Ethiopian Upper Blue Nile Basin using the SWAT+ model.
    [The authors] set up [a] SWAT+ model using quality-controlled and homogenized observational climate time series… and calibrated it using a multisite calibration approach. [They] selected CMIP6 climate models for future simulations and bias-correction methods through a comprehensive performance assessment... Building on these previous studies, the present research further evaluates the reliability of combining robust climate-model selection with optimal bias-correction methods to improve the reliability of hydrological simulations. [They] then used the best-performing climate models, bias-corrected using the optimal methods, to project future changes in blue and green water in the study area…
    KEY FINDINGS:
    • SWAT+ effectively represented hydrological processes across multiple gauging stations in the Ethiopian Upper Blue Nile Basin.
    • Ensembles of CMIP6 climate models improved the reliability of hydrological simulations compared with individual climate models.
    • Optimized climate-model selection reduced biases in hydrological simulations more than bias correction alone.
    • Arbitrary selection of climate models can degrade hydrological simulations, even when their outputs are bias-corrected using robust methods.
    • Both blue and green water are projected to increase under future climate change in the Ethiopian Upper Blue Nile Basin.
    • Blue water exhibits greater seasonality and climate sensitivity than green water flow and green water storage.
    The study also provides sustainable water management options for adapting to the impacts of climate change, with implications for water resource planning and management in the Upper Blue Nile Basin…”

  2. The #RoyalNavy has 6 Type-45 destroyers, ½ of the originally-planned 12. Design+build cost £6.5 billion at 2009 prices. Running costs more billions.

    As the #USA & #Israel started a war on #Iran, the UK had only one ship available, the #Type45 #HMSDragon, sent to Cyprus.

    Only 6 weeks later, it broke: archive.is/u5qjt

    Billions blown on a fake #blueWater navy, as the #UK cosplays a #GreatPower. The #BritishEmpire ended >50 years ago.

    Grow up Brits! Sell the ships, stop the waste.

  3. Some tropical sailing distraction can't hurt in these dark times. So let's take off for faraway Vanuatu 🇻🇺

    Cruising the archipelago of the former New Hebrides is pretty much sailing from a volcanic island to the next.

  4. A #nutria glides through a sheet of blue with only whiskers and tail breaking the calm.
    These frames feel quiet and alert at once, all ripples, reflections, and low-profile movement.
    Who knew #HulaNatureReserve could look this minimal?

  6. A boat disturbs the water

    As you may have seen over the last few days I was taking photos of the boats moored in Kinsale Harbour. Until another boat came along and sped past, disturbing the scene and rocking everything about. Still a lovely evening there, and it was about time to move on anyway. 🙂
