30% — the median of 6 frontier models, resolving by 2036-11-01.

Answer

Gemini (Google): 37% — The outcome hinges on whether localized marine air surges coincide with extreme dry-bulb heat at coastal UAE stations before 2035. Stations in nearby Bandar Mahshahr and Dhahran have touched 35°C wet-bulb briefly, establishing regional precedent for brief spikes. A sustained exceedance at standard UAE stations remains rare because sea-breeze moisture usually drops dry-bulb temperatures. Resolution would fail if stations measure 35°C only transiently rather than sustained over multi-hour intervals typically required.

Answer

Claude (Anthropic): 12% — Hinges on whether a UAE station ever records a sustained 35°C wet-bulb reading before late 2035. Persian Gulf coastal stations have recorded brief near-35°C wet-bulb spikes (e.g. Dhahran, Bandar Abbas) but sustained readings at that exact threshold remain… Climate trends through 2035 push conditions closer to the limit but models generally project reliable crossing later in the century, not within this decade. A single extreme humid heatwave event combined with marine air intrusion could tip a station over, which would most change this estimate upward.

Answer

GPT (OpenAI): 11% — Crossing 35°C requires an exceptionally rare coincidence of Gulf water warmth, humidity, and extreme air temperature. Published Gulf studies identify brief 35°C wet-bulb excursions as plausible, but UAE station records have generally remained below it. A qualifying event must occur at a standard UAE station during roughly nine summers before 2035, not merely in modeled coastal conditions. I would raise this sharply if verified stations near Abu Dhabi or Dubai exceed 33–34°C wet-bulb in coming summers.

Answer

Grok (xAI): 38% — UAE coastal stations logging a sustained Tw>35°C in one extreme summer by 2034. Gulf stations already hit 33–34.6°C Tw (2015–2023); models add ~0.4–0.6°C/decade under current forcing. A single stalled high plus high dew-point fetch from the Gulf must coincide at an official UAE site (Abu Dhabi/Dubai/RAK). Base rate of 35°C Tw globally is near-zero so far; this region sits well above it, yet 9 summers remain a short window.

Answer

DeepSeek (DeepSeek): 22% — Whether a UAE station logs a sustained 35°C wet-bulb before 2035, which no station has yet credibly done anywhere on Earth. No weather station on Earth has a verified sustained wet-bulb above 35°C; the record is roughly 33-35°C in Persian Gulf coastal sites like Bandar Mahshahr in 2015. UAE coastal stations (Dubai, Abu Dhabi, Sharjah) sit near the Gulf's warmest water, so the physical ceiling is close, but sustained 35°C requires near-saturation air… Warming of ~0.3°C per decade in Gulf wet-bulb plus urban heat island effects makes a brief exceedance plausible by the early 2030s, but 'sustained' and 'standard…

Answer

Qwen (Alibaba): 74% — Persian Gulf stations already brush 35°C wet-bulb; a single extreme humid heat event at a UAE station likely tips it over within a decade. Raymond et al. (2020, Science Advances) documented 35°C wet-bulb exceedances at Gulf-adjacent stations; UAE sites like Ras Al Khaimah reached ~34.5–35°C, sitting at the… Continued warming (~0.2°C/decade regional trend) plus increasing Gulf sea-surface temperatures raise the joint probability of extreme heat coinciding with high humidity… A single record-breaking synoptic setup—stagnant high pressure over the Gulf with onshore flow—could push a UAE station past 35°C; such events recur on multi-year…
