Does a "Boeing Memorandum" shared on social media show a real "Stratoshade" trademark for a jet fuel additive to reduce solar radiation? No, that's not true: The image, purporting to be from the "Boeing Atmospheric Management Division" contains the name "Stratoshade" followed by a trademark symbol. However there is no such trademark in the United States Patent And Trademark Office database, making it highly doubtful the memorandum is real.
The image appeared in a post on X (archived here) published on June 10, 2025. The text in the image read:
Boeing
MEMORANDUM
To: Climate Modification Teams
From: P. Hugues
Subject: Sun-Dimming Jet Fuel Additives
Date: April 27, 2024
Stratoshade™ is a special compound that uses jet fuel to reduce solar radiation.
Exhaust gases from doped fuel trigger reactions with existing base layer aerosols, reducing sunlight reflectivity by design.
THIS IS A HIGHLY CONFIDENTIAL PROGRAM!!!
DO NOT DISCUSS OR DISCLOSE THIS INITIATIVE UNDER ANY CIRCUMSTANCES.
BOEING ATMOSPHERIC MANAGEMENT DIVISION
This is what the image looked like:

It would be highly unlikely a major corporation would send a two-paragraph memorandum about a "highly confidential program" with a confidentiality notice containing three exclamation marks.
What would be even more unlikely would be that an initiative that should not be discussed or disclosed "under any circumstances" would publicly register a trademark.
A search of the United States Patent And Trademark Office database did not bring up any current or expired trademarks for the term "Stratoshade" (even though there were about 270 results for trademarks starting with variations of "stra" or containing those letters, often having to do with strategy). A search for "Stratoshade" in combination with "dimming" only brought up one result: an abandoned wordmark for something called "Streetlight.vision":
