This "entrainment" effect strengthens as climate warms and dries, increasing human heat stress.

Glaciers are particularly vulnerable due to rapid warming in mountainous regions. This "elevation dependent warming" is caused by sfc albedo and Planck feedbacks (info: https://wcd.copernicus.org/articles/5/763/2024/) https://www.bbc.co.uk/news/live/c6y8mjmnpxv0t27 Aug 2026 14:57 +0000at://did:plc:dfuvkylgpgjtk5nfl64xaeck/app.bsky.feed.post/3mu34avbq722qhttps://bsky.app/profile/drmichaelbyrne.bsky.social/post/3mt2kzf53rs2qNew study showing hot days over tropical land are projected to warm faster than the average day (bad news for climate impacts) 🌡️🔥🥵 Amplified warming of hot days is explained by the drier-get-drier theory (see: https://www.nature.com/articles/s41561-021-00828-8) https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2026GL12254014 Aug 2026 16:23 +0000at://did:plc:dfuvkylgpgjtk5nfl64xaeck/app.bsky.feed.post/3mt2kzf53rs2qhttps://bsky.app/profile/drmichaelbyrne.bsky.social/post/3msqm27emus2qWarming temperatures + decreasing relative humidity = more water being sucked from soil / reservoirs = DROUGHT. Simple physics. Europe + UK are on the frontline because they are warming so rapidly – it will get worse until 'net zero' is reached.
