Crypto journalist Jacquelyn Melinek posted that Singapore experienced severe air pollution during Token2049, and that London is now also experiencing air pollution during the Digital Asset Summit (DAS) and ahead of Solana Breakpoint, joking that nature is sending signals to crypto conferences.
In London, between November 8 and 9, particulate matter (PM2.5 and PM10) concentrations rose due to high pressure, dense fog and light winds, with some areas reaching “high” to “very high” levels. Related reports and official data attributed the cause to weekend fireworks, Diwali events, wood burning and stagnant weather conditions that caused pollutants to accumulate, rather than to the conference itself. DAS London, organized by Blockworks, is scheduled to be held on November 10 to 11 at Hilton Park Lane; Solana Breakpoint is scheduled to be held on November 15 to 17 at Olympia London.
In Singapore, during September to October 2026, cross-border haze from Indonesian wildfires caused air quality to enter the “unhealthy” range multiple times, with the PSI index rising to very high levels at some points. Token2049 was held during this period, and multiple reports mentioned the haze’s impact on outdoor activities and large events.

The overlap in timing between the two events is real, but the causal link does not hold. The haze in Singapore came from cross-border Indonesian wildfires, a regional and seasonal environmental issue; the increase in particulate matter in London was caused by a combination of local stagnant weather, fireworks and combustion emissions, which is a short-term meteorological event. Crypto conferences themselves do not produce measurable large-scale air pollution, and the marginal impact of attendee gatherings on a city’s overall air quality is limited.
This kind of observation that a conference coincides with pollution is easily amplified into a narrative. Singapore did indeed have obvious haze during Token2049, and it was widely reported in the media; London’s current pollution is also supported by official data. But linking the two independent events into a claim that nature is warning crypto conferences is humorous rhetoric rather than a verifiable environmental causal link. Similar coincidences are not uncommon at large events; they can occur when weather, wildfire season or city emission cycles overlap with conference schedules.
For the industry, what is truly worth paying attention to is the actual environmental impact assessment of large conferences, such as transport, energy consumption and local emissions, rather than blaming external pollution events on the activities themselves. Public information currently does not show that the organizers of DAS or Breakpoint adjusted their schedules or issued special health advisories because of air quality.

Timing overlap does not equal causation; when external pollution events occur during large events, meteorological and regional emission factors should first be ruled out before discussing the event’s own impact.
When social media places independent environmental events alongside industry conferences, it easily forms a narrative, but factual verification should separately confirm the pollution source and the conference schedule.
