Resolution rules

Verbatim from the venue. The analyst must quote these, never paraphrase.

If the annual global mean surface temperature anomaly has reached or exceeded +2.0°C above pre-industrial levels (1850-1900 average) in any calendar year before Jan 1, 2050, then the market resolves to Yes.

At least two of the Source Agencies must report that we have hit the 2.0°C threshold.
