“Water vapour accounts for roughly 50% of the modern greenhouse effect. Over continental regions, evapotranspiration (ET) is often limited by water availability. In this study, [the authors] spatially quantify how much of the total atmospheric water vapour evaporated most recently from land and calculate the relative contribution of that water vapour to the atmospheric radiative budget. Using a combination of tracer-enabled Earth system model simulations and radiative transfer calculations, [they were] able to explicitly quantify the 3D distribution of terrestrial vs. oceanic water vapour, and the spatial contribution of each to the surface and top of atmosphere radiative budgets. [They found] that over many continental regions, more than half of the total column-integrated water vapour originates from land ET, and that this vapour contributes up to 30 W/m² of longwave radiation into the surface in the annual mean (about 10% of the total). Understanding how terrestrial ET impacts the base-state of water vapour distribution and the water vapour greenhouse effect is critical to understanding how and where changes in terrestrial ET, driven by climate change, land use, etc, will modify the radiative properties of the atmosphere and thus the climate system…”

In college, took a course that revolved around the #book, “Environmental Problems of Greeks & Romans” by Donald Hughes.
It surprised me how the typical Greek stony #landscapes were once forested, and how philosophers wrote about erosion as it was happening.
Yet it made me appreciate monotheistic worldviews, which Baba Heru and Dr. Asa Hilliard teach existed in Kemet, and reinterpret it as oneness philosophy, which I believe has influenced the way we approach the sciences. #evapotranspiration

Global Performance of #RemoteSensing Based and Reanalysis-Driven Models to Estimate Open Water Evaporation
--
https://doi.org/10.1029/2025WR042363
--
“ABSTRACT: Evaporation plays an essential role in the water cycle, influencing local and regional climates while directly impacting water availability in lakes. However, directly measuring evaporation over water bodies remains challenging due to the high costs of installing and maintaining the required in situ instrumentation. Although several remote sensing algorithms have been providing evaporation estimates, the lack of a global validation hinders our understanding of their relative uncertainties and performances across different regions. Here, [they] analyze[d] the performance of a suite of models that leverage satellite data and meteorological reanalysis to estimate evaporation over lakes worldwide. [They] compare[d] three remote sensing-based models, one reanalysis-driven model and one ensemble approach, using in situ observations from 27 lakes representing a diverse range of geographic and climatic regions. [Their] results demonstrate that, overall, the ensemble outperformed any individual model in terms of accuracy, with a RMSE and a bias of 1.3 and 0.3 mm/day, respectively. These findings highlight the benefits of using an ensemble approach to estimate open water evaporation with satellite-based models at the global scale, leveraging the unique strengths of each model. For the individual models, differences in the representation of heat storage changes and advection effects led to lower values of RMSE and bias, depending on the location and depth of the lakes. This study sets the path for future improvement of open water evaporation algorithms globally, while remote sensing techniques are proven satisfactory to monitoring of water loss in lakes globally, an essential step toward effective large-scale water resources management.
PLAIN LANGUAGE SUMMARY: Water loss through evaporation in lakes and reservoirs directly affects water availability, which highlights the need to monitor these losses. However, measuring evaporation in situ is challenging and expensive. An alternative is to estimate evaporation using remote-sensing models and compare these estimates with in-situ data to verify their accuracy. Here, [they] evaluated four models and their ensemble (the models' mean value) using measurements from 27 lakes and reservoirs worldwide. [They] found that the ensemble presented higher accuracy and consistency than any individual model because it benefits from the strengths of each model. This approach can guide future improvements in estimating open-water evaporation, which is essential for large-scale water-resource management…”

[Flash floods? not TOO hard to conceptualise.
Flash drought? harder to 'get my head around', but H/T / presenter does an excellent job!]
"Not all droughts are the same. In some cases, drought rapidly intensifies at subseasonal to seasonal scales with significant impacts to agriculture and water resources along with the increased propensity for heatwaves and wildfires. Like all droughts, flash drought begins with a precipitation deficit. However, both evaporative demand and soil moisture are critical flash drought variables, and identifying and monitoring the desiccation of the terrestrial surface is key for determining flash drought development and associated impacts. While recent advances in knowledge and monitoring of flash drought have occurred, fundamental questions remain in the state of the science. What are the overall mechanistic relationships between atmospheric demand, evaporative stress, terrestrial desiccation, and precipitation that drive the progression of flash drought? Do regional characteristics of the environment impact the evolution of flash drought? What are the scales of predictability for flash drought? Finally, how will flash drought frequency and intensity evolve in a changing climate system"
--
"Flash drought intensifies rapidly due to changes in precipitation, temperature, wind, and radiation. These changes in the weather increase evapotranspiration and lower soil moisture. Flash droughts can cause extensive damage to agriculture, economies, and ecosystems if they are not predicted and discovered early..."

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…

What the heck is “#CornSweat” and is it making the Midwest more dangerous?
It’s pretty much just as gross as it sounds.
"In one 2020 study, researchers from the Harvard-Smithsonian Center for Astrophysics analyzed a past summer heat wave in the Midwest and found that cropland — most of which comprised corn in this part of the country — can increase moisture in the air above it by up to 40 percent."
by Benji Jones
Aug 29, 2024"Ah, yes, late August in the Midwest: a time for popsicles by the lake, a trip to the county fair, and, of course, extreme humidity made more miserable by … corn sweat.
"Corn sweat. It’s a thing! And people are talking about it.
The term refers to the moisture released by fields of corn during hot and sunny weather. Like all other plants, corn transpires — meaning, it sucks up water from the ground and expels it into the air as a way to stay cool and distribute nutrients. Moisture also enters the air when water in the soil evaporates. Together with transpiration, this process is called #evapotranspiration.
"So, where you find loads of plants packed tightly into one place, whether the Amazon rainforest or #Iowa, humidity can skyrocket during hot and especially sunny periods, making the air feel oppressive.
"That’s what happened this week: A late-summer #heatwave brought record and near-record temperatures to parts of the Midwest where there also happen to be vast fields of corn. With plenty of sunlight and temperatures in the high 90s, it was enough to make corn sweat, producing extremely uncomfortable weather.
"It’s not that corn sweats more than other plants — an acre releases less moisture on average than, say, a large oak tree — but the Midwest has a lot of corn in late August. In Iowa, for example, more than two-thirds of the area is farmland, and corn is the top crop (followed by #soybeans, which, by the way, also sweat)."
[...]
"Again, it’s not just crops across the #Midwest that release moisture, increase humidity, and make summers feel disgusting (I know firsthand; I grew up in Iowa). The millions of acres of #prairie that industrial farmland replaced — mostly to feed livestock and make ethanol — would have also produced loads of moisture, Basso said.
"But there are some key differences between native #ecosystems and #IndustrialFarmland, he added. '#NativePrairies are diverse ecosystems with a variety of plant species, each with different root depths and water needs, helping to create a balanced moisture cycle,' he told me. 'In contrast, corn and #soy #monocultures are uniform and can draw water from the soil more quickly.'"

‘Corn Sweat’ and #ClimateChange Bring Sweltering #Weather to the #Midwest
The #heat is accompanied by #humidity from two sources: moist air that is streaming up from the Gulf of Mexico and a phenomenon that is sometimes called “#cornsweat.” The latter happens when #corn, #soybeans and other crops release moisture as the temperature climbs. This process, known technically as #evapotranspiration, is akin to how humans perspire in the heat.

Deforestation has big impact on regional temperatures
"...Deforestation causes warming at distances up to 60 miles away. The greater the forest clearance, the higher the temperature. This is in addition to the wider climate impact of global heating."
“We show that regional forest loss increases warming by more than a factor of four with serious consequences for the remaining Amazon forest and the people living there.”
“More and more, we are demonstrating the big benefits the forests bring to surrounding regions. For farmers, they bring cooler air and more rainfall. Until now, studies on the impact of forest clearance on heat have concentrated on local effects with a clear correlation between loss of tree cover and higher temperatures in the area where the trees were cut down. The new research went further by looking at whether there is also a warming effect over a wider area." >

"Tropical deforestation warms the climate with negative impacts on people living nearby." >
