The exceptionally wet conditions in Viet Nam have led to widespread flooding. In this image, acquired by one of the Copernicus Sentinel-1 satellites on 27 October 2025, flooded areas along the Vu Gia and Thu Bồn rivers near Ái Nghĩa, Điện Bàn, and Hội An appear in blue tones.

The Vietnamese Bach Ma Mountain Peak station recorded one-day rainfall of 1,739 mm - close to the global one-day record and perhaps a new record for the northern hemisphere. It is part of a deluge Viet Nam has seen in October, shattering 35 precip records. e.vnexpress.net/news/news/en...
Vietnam sees 35 rainfall records broken in October - VnExpress International
Vietnam's northern and central regions saw a total of 35 rain records broken in October alone as two storms, Matmo and Fengshen, caused unprecedented downpours.

Why did GHG emissions rise?
50% of the increase was from land-use change, primarily due to more fires during El Niño. We expect this to drop in 2025. LUC is also very uncertain.
All other main regions, except EU27, with rising emissions in 2024.

What a magnificent and scary example of a Glacial Lake Outburst Flow. Melting glaciers can produce surprises like this.
This footage from USGS shows the Mendenhall Glacier in Alaska forming a natural ice dam. As meltwater builds up and suddenly releases, it triggers a glacial lake outburst flood (GLOF).
The cryosphere is changing, and with it, the risks we face.

A massive storm that brought a record storm surge to Alaska was poorly forecast, and “this is one of the clearest possible examples to date where missing upper air soundings due to NWS constraints may have led to a degraded forecast.”
Sunday a massive storm surge event from the remnants of Typhoon Halong caused catastrophic damage in remote western Alaska. Thanks to @alaskawx.bsky.social for his help with this deep dive, including the forecast challenges in an area dealing with reduced NWS upper air soundings

Historic coastal flooding strikes western Alaska
Remnants of Typhoon Halong produce hurricane force winds and push massive storm surge inland in Kuskokwim River Delta, destroying and carrying away homes, leaving devastated communities.
