## Question
What will be the weekly cumulative burnt areas (ha) from forest fires in the EU on August 26, 2026?

## Description / Resolution Criteria
## Description
The European Forest Fire Information System (EFFIS) was established by the European Commission in collaboration with the national fire administrations to support the services in charge of the protection of forests against fires in the EU and neighbor countries. The EFFIS consists of a "modular web geographic information system that provides near real-time and historical information on forest fires".

In July 2026, [forest fires have made headline news](https://www.france24.com/en/europe/20260723-wildfires-ravage-spain-france-and-italy-killing-three-firefighters). The impact has been shown in [the EFFIS data](https://forest-fire.emergency.copernicus.eu/apps/effis.statistics/seasonaltrend):

| Week Up To    | Cumulative Burned Area (ha) | Change From Previous Week |
| ------------- | --------------------------- | ------------------------- |
| June 24, 2026 | 111,754                     | 4.15%                     |
| July 1, 2026  | 126,829                     | 13.49%                    |
| July 8, 2026  | 165,302                     | 30.33%                    |
| July 15, 2026 | 197,400                     | 19.42%                    |
| July 22, 2026 | 303,777                     | 53.89%                    |

`{"format": "metac_reveal_and_close_in_period", "info": {"post_id": 44791, "question_id": 44938}}`

## Resolution Criteria
This question will resolve as the total burnt area (ha) in the EU displayed for the week up to August 26, 2026 in the [EFFIS Weekly Cumulative Burnt Areas graph](https://forest-fire.emergency.copernicus.eu/apps/effis.statistics/seasonaltrend) for the year 2026, as soon as that data is first displayed.

## Fine Print
Any subsequent revisions to the data will not count towards the resolution of this question.

***
This question's information (resolution criteria, fine print, background info, etc) is synced with an [original identical question](https://www.metaculus.com/questions/44791) which opened on 2026-07-27 17:00:00. This question will resolve based on the resolution criteria and fine print of the linked original question. However, if this question would resolve differently than the original question, then this question will be annulled. Additionally, if the original question's resolution could have been known before this question opened, then this question will be annulled.

## Range
The answer must be a number in [450000, 750000] (units: ha).

## Sub-question decomposition (planner)
- (w=0.35) Will the EU cumulative burnt area reported by EFFIS for the week up to August 26, 2026 exceed 500,000 ha (i.e., roughly a 1.65x or larger multiple of the 303,777 ha reported for July 22, 2026)?  — Anchors the central mass of the distribution; historically the late-July-to-late-August window adds a large but variable
- (w=0.20) Will the August 2026 increment be extreme, pushing the August 26, 2026 cumulative total above 750,000 ha?  — Captures the fat right tail (e.g., 2017, 2022, 2025-type August mega-fire episodes in Iberia/Balkans) which dominates th
- (w=0.25) Will August 2026 see at least one major new heatwave/wildfire emergency in Spain, Portugal, Greece, Italy or the Balkans generating international headlines and large evacuations before August 26?  — August fire activity is driven by discrete heatwave/drought episodes; presence or absence of such an episode is the main
- (w=0.20) Will the increase from July 22 to August 26, 2026 be modest, keeping the cumulative total below 425,000 ha (less than ~1.4x)?  — Covers the low-end scenario where the July burst was front-loaded and cooler/wetter August conditions flatten the curve;

## Required pre-forecast walkthrough

Before giving percentiles, address these explicitly in your rationale:
  (a) The time left until the question resolves.
  (b) The outcome if NOTHING changes from today (the status quo value).
  (c) The outcome if the CURRENT TREND continues.
  (d) The expectations of experts / markets / base rates.
  (e) A plausible scenario that produces a LOW outcome (near p10).
  (f) A plausible scenario that produces a HIGH outcome (near p90).

## Calibration guidance

- **Be humble about tails.** Good forecasters set WIDE 90/10 intervals to account for unknown unknowns. Narrow tails get punished by the log score far more than slightly-biased medians.
- **Status quo anchoring.** The p50 should be close to the status quo value unless you have strong evidence of a trend.
- Don't pile mass at one value — if you're tempted, widen the spread by 20-50%.
- **Anchor on markets/experts.** If liquid market prices, analyst forecasts, or community percentiles appear in the evidence, center your distribution on them and widen — don't override a liquid market without specific evidence it lacks.
- **Relative-return / spread questions ("how much will X's return exceed Y's").** A near-zero median is usually right, but size the TAILS to the more VOLATILE leg, not to a generic 2-3pp spread. Two broad equity indices (e.g. Nasdaq-100 vs S&P 500) do stay within roughly ±2-3pp over a two-week window. But when one leg is a commodity (crude oil, gold) or a single high-beta stock (e.g. Nvidia), the two-week realized spread regularly reaches ±10pp or more — crude-vs-equity spreads have hit ±18pp. In those cases set p10/p90 to at least ±10pp (±15pp or wider for oil) while keeping the median near the status-quo spread; the 2-3pp intuition applies only to index-vs-index.
- **Heavy-tailed one-off magnitudes (opening-weekend box office, product-launch or debut numbers).** Pre-event tracking for these routinely misses by ±40% or more, and results land both far above and far below the consensus. Do NOT treat the displayed [min, max] range as the plausible range or clamp p10/p90 to its edges: the outcome can fall outside the range in either direction (recent opening weekends resolved ~7% above a displayed ceiling in one case and roughly half the displayed floor in another). Set p10/p90 wide enough that a 2x-or-0.5x surprise versus your central estimate still lands inside the interval, and when concrete current tracking disagrees with historical/franchise base rates, weight the tracking.

[sq1 | wikipedia_lookup | WEAK cred 30 | NEUTRAL | VERY_RECENT] Wikipedia\u0027s \u0027Wildfires in 2026\u0027 article is a stub with no detailed EU August 2026 fire data, providing no direct evidence on post-July developments.\n\n## Cross-Market Signals\n\n### No signal found\n\nInformation gaps:\n  - No verified year-by-year EFFIS Jul-22 vs Aug-26 cumulative values; simulation ratios are unsourced/possibly synthetic\n  - No actual EFFIS data for weeks after July 22, 2026 (Jul 29\u2013Aug 26)\n  - Unclear how much of 2026\u0027s total is non-summer (winter/spring) burning that won\u0027t repeat in August\n  - No data on EFFIS revision magnitude between first-published and later weekly figures\n\nKey uncertainties:\n  - Whether the forecast early-August heat dome materializes into large Iberian megafires\n  - Whether Greece/Balkans (typically August-heavy) ignite before Aug 26\n  - Fat-tailed nature of burnt-area distributions \u2014 single events can add 100k+ ha\n  - Exact first-displayed EFFIS value versus later revisions\n\n## Required pre-forecast walkthrough\n\nBefore giving percentiles, address these explicitly in your rationale:\n  (a) The time left until the question resolves.\n  (b) The outcome if NOTHING changes from today (the status quo value).\n  (c) The outcome if the CURRENT TREND continues.\n  (d) The expectations of experts / markets / base rates.\n  (e) A plausible scenario that produces a LOW outcome (near p10).\n  (f) A plausible scenario that produces a HIGH outcome (near p90).\n\n## Calibration guidance\n\n- **Be humble about tails.** Good forecasters set WIDE 90/10 intervals to account for unknown unknowns. Narrow tails get punished by the log score far more than slightly-biased medians.\n- **Status quo anchoring.** The p50 should be close to the status quo value unless you have strong evidence of a trend.\n- Don\u0027t pile mass at one value \u2014 if you\u0027re tempted, widen the spread by 20-50%.\n- **Anchor on markets/experts.** If liquid market prices, analyst forecasts, or community percentiles appear in the evidence, center your distribution on them and widen \u2014 don\u0027t override a liquid market without specific evidence it lacks.\n- **Relative-return / spread questions (\"how much will X\u0027s return exceed Y\u0027s\").** A near-zero median is usually right, but size the TAILS to the more VOLATILE leg, not to a generic 2-3pp spread. Two broad equity indices (e.g. Nasdaq-100 vs S\u0026P 500) do stay within roughly \u00b12-3pp over a two-week window. But when one leg is a commodity (crude oil, gold) or a single high-beta stock (e.g. Nvidia), the two-week realized spread regularly reaches \u00b110pp or more \u2014 crude-vs-equity spreads have hit \u00b118pp. In those cases set p10/p90 to at least \u00b110pp (\u00b115pp or wider for oil) while keeping the median near the status-quo spread; the 2-3pp intuition applies only to index-vs-index.\n- **Heavy-tailed one-off magnitudes (opening-weekend box office, product-launch or debut numbers).** Pre-event tracking for these routinely misses by \u00b140% or more, and results land both far above and far below the consensus. Do NOT treat the displayed [min, max] range as the plausible range or clamp p10/p90 to its edges: the outcome can fall outside the range in either direction (recent opening weekends resolved ~7% above a displayed ceiling in one case and roughly half the displayed floor in another). Set p10/p90 wide enough that a 2x-or-0.5x surprise versus your central estimate still lands inside the interval, and when concrete current tracking disagrees with historical/franchise base rates, weight the tracking.\n\n## Output\n\nReturn ONLY valid JSON, no markdown fences:\n\n{\n  \"rationale\": \"\u003caddress (a) through (f) above, then state your distribution \u2014 6-10 sentences total\u003e\",\n  \"p10\": \u003cnumber\u003e,\n  \"p25\": \u003cnumber\u003e,\n  \"p50\": \u003cnumber\u003e,\n  \"p75\": \u003cnumber\u003e,\n  \"p90\": \u003cnumber\u003e\n}\n\nPercentiles MUST be in non-decreasing order (p10 \u003c= p25 \u003c= p50 \u003c= p75 \u003c= p90).\n",

(b) Status quo (no further burning, which is impossible in a Mediterranean August) would leave the cumulative near 305\u2013325k ha, below the question\u0027s floor. (c) If the current trend continues \u2014 weekly increments of 15\u201350% in late July, then the typical decelerating-but-substantial August accumulation \u2014 the total lands around 500\u2013600k ha. (d) Base-rate simulation of historical late-Jul\u2192late-Aug EFFIS ratios (median ~1.75x, range ~1.15\u20133.5x; 2022 was flat, 2021/2023/2025 were steep) gives P(\u003e500k)\u22480.6, P(\u003e750k)\u22480.10, P(\u003c425k)\u22480.19; note also that the first-displayed weekly value tends to be revised upward later, so the resolving number is somewhat conservative, and an unusual share of 2026\u0027s total came from winter/spring burning that won\u0027t recur. (e) LOW scenario: the July heat episode was the season\u0027s peak, Atlantic troughs cool Iberia/France in August, Greece and the Balkans stay quiet, and the total creeps only to ~380\u2013460k ha (a real possibility, part of it below the question floor). (f) HIGH scenario: the forecast early-August heat dome plus severe soil-moisture deficit ignites Iberian megafires and Greece/Balkans burn in mid-August, adding 300\u2013400k ha in two weeks as in 2025, pushing the total to 700k\u20131M ha. Balancing a median ratio of ~1.7\u20131.8x against a modest downward adjustment for first-publication lag and non-summer front-loading, I centre near 540k ha with a wide, right-skewed spread, acknowledging meaningful mass below the 450k floor and above the 750k ceiling."
