تعاني ولايات في غرب الولايات المتحدة من مستويات تراكم ثلوج من أدنى المستويات في عقود خلال منتصف الشتاء. تتزامن هذه الأزمة مع صعوبات مستمرة بين الجهات التنظيمية للتفاوض على حقوق المياه في المنطقة. تثير الوضعية مخاوف بشأن صيف أكثر جفافًا وزيادة مخاطر الحرائق.

في غرب الولايات المتحدة، وصلت مستويات تراكم الثلوج إلى أدنى مستويات قياسية في منتصف موسم الشتاء، مما يؤثر على منطقة واسعة عبر عدة ولايات. هذه المستويات هي الأدنى التي شوهدت في عقود، وفقًا لتقارير من Wired. من المتوقع أن يؤدي تراكم الثلوج المنخفض إلى انخفاض توافر المياه وزيادة خطر الحرائق البرية خلال الصيف القادم. يفاقم المشكلة فشل سبع ولايات غربية في الوفاء بموعد نهائي للاتفاق على شروط مشاركة المياه في حوض نهر كولورادو. يوفر هذا الحوض المياه لـ40 مليون شخص في المنطقة. كانت الجهات التنظيمية تكافح في مفاوضات حول حقوق المياه وسط هذه التحديات. يبرز الجمع بين تراكم الثلوج المنخفض والاتفاقيات المياه المتوقفة ضغوطًا بيئية أوسع في الغرب، بما في ذلك تلك المتعلقة بالمناخ وأنماط الطقس. بينما يركز الاهتمام الفوري على ظروف الشتاء الحالية، تمتد الآثار إلى إدارة المياه والاستعداد للحرائق في الأشهر الأكثر دفئًا القادمة.

Study finds most U.S. states are warming in uneven ways that averages can miss

A study in PLOS Climate reports that U.S. warming trends vary sharply by state and by whether researchers look at temperature averages or extremes. Using data from 1950 to 2021 for the 48 contiguous states, the authors found that 27 states showed statistically significant increases in average temperature, while 41 showed warming in at least one part of their temperature range—such as hotter highs in parts of the West and warmer cold-season lows in parts of the North.

Western US enters spring with record-low snowpack and heat risks

Much of the Western United States has experienced one of its warmest winters on record, leaving snowpack at historic lows and prompting warnings of drought and wildfires this summer. An early March heat wave pushed temperatures into triple digits across multiple states. Experts describe the conditions as unprecedented, with no historical parallels.

Ski resorts increasingly rely on snowmaking amid low western US snow

26 فبراير، 2026 من إعداد الذكاء الاصطناعي

This winter marks the lowest snow cover on record in the Western United States, forcing ski resorts to depend more on machine-made snow. While this practice helps maintain operations, it raises concerns over energy and water use. Experts highlight both environmental challenges and adaptation limits as climate change alters winter conditions.

South African weather service forecasts drier winter for southwest

The South African Weather Service has updated its forecast to predict below-normal rainfall in the southwestern and southern coastal parts during winter until August. This drier outlook raises concerns for the winter wheat crop amid rising fuel and fertiliser prices linked to the Iran conflict. Eastern coastal areas may see above-normal rain, heightening flood risks.

Mountains warm faster than lowlands, global review shows

21 يناير، 2026 من إعداد الذكاء الاصطناعي

Mountains around the world are heating up more quickly than surrounding lowlands, according to a comprehensive study, leading to shifts in snow, rain, and water supplies that affect over a billion people. The research highlights elevation-dependent climate change, with temperatures rising 0.21°C per century faster in mountain regions. These changes pose risks to ecosystems, water resources, and human safety in areas like the Himalayas.

Utah pushes data centers amid Great Salt Lake water concerns

Utah's leaders are promoting the state as a data center hub while pledging to restore the shrinking Great Salt Lake, raising questions about water use in a drought-prone region. Governor Spencer Cox insists most facilities do not consume much water, but new legislation aims to increase transparency on their consumption. Environmental advocates and lawmakers call for better oversight to balance economic growth with conservation efforts.

Nevada shatters March heat record by 6 degrees

Nevada broke its statewide March high temperature record by 6 degrees Fahrenheit during a mid-March heat wave, amid the collapse of the region's snowpack. Laughlin reached 106°F, surpassing the previous record of 100°F. The event occurred during the 11 warmest years on record from 2015 to 2025, according to the World Meteorological Organization.
