CAMe activa la fase 1 de contingencia ambiental por ozono en el Valle de México

<think> Okay, the user provided materials about a news article and wants me to act as a journalist for Global24, writing an original news synthesis in neutral Spanish. Let me start by carefully reading the instructions.

First, I need to extract the key information from the given materials. The main headline is about CAMe activating phase 1 of environmental contingency due to ozone in Mexico City. The source is La Jornada, dated September 12, 2026. There are related headlines, but they seem unrelated to the main topic, so I should focus only on the primary news.

The user specified that the synthesis must be exactly two short paragraphs separated by a blank line, max 110 words total. Tone must be informative and neutral. I can't copy phrases verbatim or invent data. If the material is scarce, I should only describe what the source reported and the general context.

Looking at the provided material, the main news is clear: CAMe activated phase 1 due to ozone levels. I need to paraphrase this without using exact phrases. I should mention the source, date, and the action taken. The related headlines are about Trump, a celebrity, and dollar exchange rates, which are irrelevant here, so I'll ignore them.

I need to ensure the synthesis is original, in neutral Spanish, and within the word limit. Let me count the words as I draft. First paragraph should state the fact, source, and date. Second paragraph can add context about the contingency phase and ozone, but only if mentioned in the material. The material doesn't specify details about phase 1, so I should stick to what's given.

Wait, the user said if material is scarce, limit to describing what the source reported and general context. Here, the main info is the activation due to ozone. I should avoid adding extra details not in the material. Also, ensure no direct quotes, neutral tone, exactly two paragraphs.
