Taken directly from the link:

Firstly, all stakeholders who use the IPC for high-level decision-making must understand that whether a Famine classification is confirmed does not in any manner change the fact that extreme human suffering is without a doubt currently ongoing in the Gaza Strip and does not in any manner change the immediate humanitarian imperative to address this civilian suffering by enabling complete, safe, unhindered, and sustained humanitarian access into and throughout the Gaza Strip, including through ceasing hostilities. All actors should not wait until a Famine classification for the current period is made to act accordingly.

tl;dr just because it doesn’t mean their official classification requirements doesn’t mean it isn’t happening, or that there isn’t widespread human suffering.

Innocent people are still starving and in danger as a result of this war and it’s fucking horrible.
