Executive summary

No definitive, publicly released evidence identifies who started the January 2026 wildfires in Argentine Patagonia; some national officials pointed at Mapuche groups but local judicial authorities in Chubut said there was insufficient proof to back that claim [1]. Investigations and reporting instead emphasize a mix of factors—human activity as a common ignition source, extreme drought and heat linked to climate change, and a politically charged atmosphere that has produced competing and sometimes conspiratorial accusations [2] [1] [3].

1. The headline claims: government mentions Mapuche, courts push back

Argentina’s national government publicly suggested Mapuche groups could be possible perpetrators of the Patagonian fires, a statement that quickly entered headlines and political debate [1]. Judicial authorities in Chubut explicitly rejected that claim on the grounds that there was no evidence to support it, undercutting the executive branch’s implication and leaving the question of responsibility officially open [1].

2. What investigators and news agencies report about causes

Reporting from international wire services and local outlets frames the blazes as part of a broader pattern of summer fires across Patagonia but does not point to a proven, single arsonist or organized group responsible for the January outbreaks; coverage instead documents widespread burning, evacuations and firefighting activity [4] [5] [6]. Official firefighting sources focus on containment and resource deployment—hundreds of personnel, aircraft from Argentina and Chile, and provincial coordination—rather than naming confirmed suspects [7] [5].

3. Human ignition vs. deliberate conspiracy: the evidence gap

Multiple sources note that the vast majority of wildfires are caused by human actions—whether negligence or deliberate acts—but specific attribution for these particular fires remained unproven in the available reporting [2]. Local officials in Chubut stated a belief that some fires were started intentionally and even offered a monetary reward for identifying those responsible, yet that belief did not equate to verified culpability in judicial terms [2] [8].

4. Conspiracy narratives and the “Israeli” accusation

A virulent stream of social and political commentary accused Israeli tourists or agents of starting fires—a claim repeated by some public figures and amplified on social media—but contemporary reporting shows these allegations are anecdotal and unverified, and in prior unrelated incidents in Chile investigators concluded negligence, not coordinated arson [9] [10]. Prominent public figures repeating such claims, including retired military officers and politicians, have been documented spreading versions of the Israeli-grenade allegation, which multiple outlets flag as conspiratorial and antisemitic [10] [9].

5. Climate and structural context that complicates attribution

Scientists and environmental organizations cited extreme drought—described by officials as the worst since the 1960s—and higher temperatures as factors that increase both ignition risk and rapid spread of fires, meaning that even accidental sparks can become catastrophic under current conditions [1] [3]. Greenpeace and others quantified the scale of the blazes in 2026 and 2025 to show this is part of a worsening trend rather than an isolated incident [1] [3].

6. Political incentives, media amplification, and investigative limits

The speed with which accusations circulated—against indigenous activists, foreign tourists, or specific foreign actors—reflects local political contests and the wider optics of a national government eager to assign blame, while courts and independent outlets caution against premature conclusions for lack of evidence [1] [10]. Reporting to date is constrained by active investigations, limited forensic detail in the public record, and ongoing emergency response, meaning definitive judicial findings were not available in the cited coverage [1] [4].

7. Conclusion: responsible answer to “who did them?”

Based on the cited reporting, no verified perpetrator has been publicly established for the January 2026 Patagonia wildfires; government statements pointing at Mapuche groups have been legally contested for lack of evidence, and other circulating theories—including claims involving Israeli nationals—remain unverified and politically charged [1] [10] [9]. Independent observers and emergency agencies emphasize human causes in general and climate-amplified conditions in particular, but attribution in any specific legal sense requires more forensic and judicial evidence than is available in the current coverage [2] [3].
