6 天之前 · We quantify baseline and future water gaps using a multi-model analysis that incorporates two plausible future warming scenarios. The baseline global water gap stands at 457.9 km3/yr, with ...

Climate policymakers must put water at the heart of action plans. Sustainable water management helps society adapt to climate change by building resilience, protecting health and saving lives. It also mitigates climate change itself by protecting ecosystems and reducing carbon emissions from water and sanitation transportation and treatment.

2024年3月15日 · Climate change is disrupting weather patterns, leading to more frequent and more intense extreme weather events, unpredictable water availability, exacerbating water scarcity and contaminating water supplies.

2024年3月27日 · We demonstrate the projected response of the water cycle to global warming in different seasons utilizing the Coupled Model Intercomparison Project Phase 6. Winter in the DEA presents an intensification of the water cycle, reflected in coherent increases in evapotranspiration (E), precipitation (P), runoff, and surface soil moisture.

2023年4月3日 · Climate change will likely exacerbate water stress worldwide, as rising temperatures lead to more unpredictable weather and extreme weather events, including floods and droughts. Billions of...

2022年4月14日 · Because we’re already seeing how a warming world affects our access to freshwater, experts say we need to act now. Climate scientists say that limiting global warming at 1.5 degrees Celsius or below—the goal of the Paris Agreement—would dramatically reduce the risk of increased droughts and other water-related impacts. 12

About two billion people worldwide don’t have access to safe drinking water today (SDG Report 2022), and roughly half of the world’s population is experiencing severe water scarcity for at...

2024年6月4日 · Focusing on diffusive heat transport, we simulate current and projected groundwater temperatures at the global scale. We show that groundwater at the depth of the water table (excluding...

2025年1月9日 · 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...

2019年9月23日 · Climate change impacts the world’s water in complex ways. Consider a water cycle diagram, like the one below; global warming is altering nearly every stage in the diagram. These changes will put pressure on drinking water supplies, food production, property values, and more, in the U.S. and all around the world. Image: UK Met Office
