1. Lancet Countdown report attributes about 3 million deaths in 2016-2023 to global warming

   The 2026 report of the Lancet Countdown on health and climate change said about 3 million deaths between 2016 and 2023 can be attributed to global warming, the first time the team has directly quantified heat-related deaths caused by human-driven climate change. Published ahead of the COP31 climate conference, the report said heat-related deaths have kept rising since the 2015 Paris Agreement. It said renewable energy growth has 'far exceeded expectations' and could cut warming by 2100 from a previously estimated 3.5°C to 2.6°C, but global climate action remains 'severely inadequate'.

2. Classification of finite simple groups fully formalised in Lean, uncovering a counterexample in a published proof

   A research project announced it has completed a full formalisation of the classification of finite simple groups in the Lean proof assistant, following the first-generation proof, with every logical step checked by Lean's kernel. The theorem is regarded as one of mathematics' greatest collective achievements; its first-generation proof was written by about 100 mathematicians over decades and runs to thousands of journal pages, concluding that every finite simple group is a cyclic group of prime order, an alternating group, a group of Lie type or one of 26 sporadic groups. During the work, the team found a counterexample to a closure claim used in one published route to the proof of the 'unbalanced group theorem', gave an alternative argument, and is preparing an erratum with group theorists.

3. IAEA says global nuclear power could more than triple by 2060, driven by AI data centres and electrification

   IAEA Director General Rafael Grossi presented the agency's annual report to the UN General Assembly on Oct 23, forecasting that global nuclear power use could more than triple by 2060, driven by electrification, AI data centres and tech companies' demand for stable carbon-free power; it is the fifth straight year the agency has raised its forecast. In the high-growth scenario, global nuclear capacity would reach 992 GW in 2050, 2.6 times the 2024 level, with small modular reactors making up about 28%. Grossi said more than 400 reactors in over 30 countries supplied 10% of the world's electricity in 2025, and more than 60 new reactors are under construction.

4. WMO says this El Niño could be the strongest on record, with tropical Pacific sea temperatures up to 3.8°C above average

   World Meteorological Organization Secretary-General Celeste Saulo said in Geneva on Thursday, Oct 22, that the current El Niño could reach unprecedented strength, beyond more than 40 years of monitoring records. The latest forecasts show tropical Pacific sea-surface temperatures could be 3.8°C above average from November to January, compared with about 3°C for the strongest El Niño on record; she said it would peak at the end of this year but its effects would last longer, with extreme weather already seen worldwide set to 'multiply and cascade'. KBS said South Korea is bracing for sharp temperature swings and record rain and snow.

5. IUCN's first global assessment finds 96% of coral reefs critically endangered once warming is factored in, facing collapse risk by 2075

   The Guardian and Japan Times reported the International Union for Conservation of Nature's first global coral reef assessment, covering reefs in more than 80 countries, found about 24% are currently critically endangered, rising to 96% when expected global warming is included, with almost all shallow-water reefs, including Australia's Great Barrier Reef, at high risk of ecosystem collapse by 2075. About a quarter of known marine species live on or around coral reefs. Mishal Gudka, the assessment's scientific lead and a research director at Cordio East Africa, said 'the risk is real and very concerning'.

6. Follow-up: PHP patches two critical remote-code-execution flaws; government websites in several European countries briefly taken offline

   The PHP project's official blog said PHP released versions 8.5.12, 8.4.27, 8.3.36 and 8.2.35 on Oct 21 to fix two critical vulnerabilities that, under certain conditions, let unauthenticated attackers execute code on servers running PHP; the flaws are in memory management and error handling used by almost every request. Asahi said the fixes came out late on Oct 21 Japan time and some websites were still down on the morning of Oct 22, while government agency websites in several European countries suspended service. The US National Security Agency on Oct 21 Eastern Time told all agencies using PHP to act and to take systems offline if they could not patch immediately; the FBI also issued a warning on X.
