From record heat to violent storms. Lightning struck the Eiffel Tower Saturday evening as thunderstorms swept across Paris following days of extreme temperatures that shattered heat records across France. Health officials say the deadly heat wave is linked to at least 1,000 excess deaths over three days, with the...

Satya Nadella: Microsoft’s latest Wisconsin AI data center keeps yearly water consumption no higher than that of 1 local restaurant. "The cooling loop is filled once and the data centre can operate effectively with zero water consumption. Daily water usage across a year is roughly equivalent to what a single restaurant would use" The mechanism is mainly about replacing evaporative cooling with closed-loop direct-to-chip liquid cooling, so water moves like coolant inside a sealed machine rather than being boiled off into the air. Hot GB200-class AI racks produce too much heat for normal air cooling, so cold liquid is pushed through pipes into the servers and across metal cold plates touching the hottest chips. The liquid enters the rack cool, absorbs heat from the chips through cold plates, then exits the rack at a higher temperature and carries that heat through pipes to a huge cooling system outside the compute floor. Microsoft says Fairwater sends that hot water to cooling “fins” beside the datacenter, where 172 20-foot fans blow air across the fins and dump the heat into the outside air. The important detail is that the air cools the water through metal surfaces, so the water does not need to evaporate the way many older datacenters use cooling towers. The cooled liquid then returns to the servers, repeats the loop, and keeps absorbing heat from the chips. In older data centers, heat is often removed partly through cooling towers. Hot water meets moving air, some water evaporates, and that phase change carries heat away. Effective, but it consumes fresh water continuously. But Firwater is a closed loop because the same coolant keeps circulating through sealed pipes: it absorbs heat from the chips, releases that heat through radiator-like fins, then flows back to the chips again. For Wisconsin Fairwater, Microsoft says more than 90% of the facility uses closed-loop liquid cooling, while the remaining portion uses outside air and switches to water only on the hottest days. ---- From "Microsoft" YouTube channel, (link in comment)

☀️12th April 2026: India Under the Dome: 6-Day Intense Dry Spell to Grip Subcontinent. The loan oasis, Northeast India Defies National Trend with Rain and Thunderstorms until 15th April. ​Mercury Surge: Central and South India Brace for 40°C+ as High Pressure Caps the Skies ​ Detailed Forecast & Analysis ​1. The Dominant "Heat Dome" Effect ​The orange and red anomalies in the loop represent positive geopotential height anomalies. This indicates a high-pressure system (anticyclone) at the 500mb level (approx. 5.5 km altitude). ​The Cause: This system acts like a "lid" or dome, trapping sinking air which warms up as it is compressed. This suppresses cloud formation and prevents moisture from the oceans from penetrating inland. ​Impact: Expect a rapid rise in maximum temperatures by 3–6°C across Northwest, Central, and East India. Example, cities like Delhi, Nagpur, and Ahmedabad are likely to approach or exceed the 40°C mark by April 15. ​2. Regional Breakdown Region Weather Outlook (Next 6 Days): Primary Driver Northwest & Central Severe dry heat; clear skies; rising heatwave risks. Strong anticyclonic subsidence. South Peninsular Hot and humid; minimal rainfall. High-pressure stability. East India Significant temperature spike (3–5°C rise). Expansion of the heat ridge eastward. Northeast India Scattered thunderstorms & light-to-moderate rain. Persistent 3. The Northeast Exception until 15th April. ​The red arrow in the loop image points to a specific area (Northeast India/Bangladesh border) where the high-pressure dome is weaker or interrupted. ​The Cause: A "trough" (an elongated area of low pressure) is expected to persist over this region. This allows moisture from the Bay of Bengal to interact with the hilly terrain, triggering Orographically induced thunderstorms. ​Expected Conditions: While the rest of India stays dry, states like Assam, Meghalaya, and Arunachal Pradesh will likely see fairly widespread rainfall and gusty winds 30–40 kmph through April 16. ​Preparation Advice ​Agriculture: Farmers in Central and West India should ensure adequate irrigation for summer crops as soil moisture will deplete rapidly. ​Health: High UV indices 9–10 are expected; avoid outdoor activity between 11 AM and 4 PM in heat-affected zones. ​Northeast Residents: Prepare for sudden squalls and lightning; ensure drainage systems are clear for localized heavy spells.
