    A clearer view of Earth’s water cycle via neural networks and satellite data

    To manage and protect water resources, it is necessary to understand the water cycle. Passive microwave radiometers onboard satellites are used to monitor water resources, like soil moisture. However, microwave sensors, such as radiometers, are too coarse to see small-scale meteorological features, which can affect large-scale phenomena occurring within the water cycle. Other spaceborne instruments produce finer-resolution images, but these instruments are much more sensitive to cloud contamination, limiting their useful coverage. More

    Author Correction: Storing frozen water to adapt to climate change

    In the version of this article initially published, there was a misstatement in the third paragraph, fourth sentence, now reading in part, “Now hundreds of farmers and villagers in this cold, arid desert use the ice stupas to save the water that flows in autumn,” where “hundreds” has replaced “dozens.”. In the fifth from last paragraph, “University of Applied Sciences in Lucerne” has replaced “….Life Sciences.”After this article was published, a highly relevant paper followed, which is now referenced to enhance understanding. It is cited in the eighth paragraph, following the quote “‘Seventy-eight percent of the water used is lost during the ice stupa formation,’ said Balasubramanian6,” and provided below. The changes have been made to the HTML and PDF versions of the article. More

    Water use in a changing world

    Estimating future economic and domestic water use is difficult due to uncertain changes in climate and socioeconomic conditions. Now, research estimates future water use in the United States could decrease or more than double by 2070 under plausible socioeconomic and climate scenarios.Between 1980 and 2015, the United States added more than 82 million people (34% increase), generated 1,786 billion kWh more electricity annually (78% increase), and irrigated 2.4 million more hectares of cropland each year (10% increase). Yet, surprisingly, during this same period, total annual water withdrawals decreased by nearly 150 billion m3 (25% reduction)1,2. Given the importance of water in meeting our basic needs and supporting economic activity, long-term forecasts of societal water use are required to ensure that enough water is available to meet future water needs. However, uncertainties in future climate and socioeconomic conditions make it difficult to predict future water use. Recent research reported in Earth’s Future by Warziniack and colleagues3 introduces a novel approach to project freshwater use in the United Sates through 2070. They find that water consumption could decrease by as much as 8% or increase up to 235% under different socioeconomic and climate scenarios. More
