Misleading. Useful information, but the definitions are misleading.

This is based on projections of the remainder of 2023.
This is based on a 1-year measurement in the middle of an El Niño rather than a 5-year rolling average.
This assumes a lower holocene optimum than organizations like NOAA use. NOAA is calling this a 1.25°C anomaly.

We haven't hit 1.5°C yet, at least not by the conventional definitions. So the next time you see the IPCC outlining mitigation pathways to keep warming to 1.5°C, please don't go posting this article saying, "we already passed that point lol."
