MISSOURI CITY, MO — A Missouri community college student says an English composition quiz turned into a surprising lesson in fact and opinion after the instructor marked “global warming is a fact” wrong. The student, who posts on Reddit under the name DerCatrix, shared a screenshot of the question and said they answered yes because they believed the statement was factual.
Instead of a simple grading error, the student said the exchange grew stranger after an email to the teacher. According to the post, the instructor said she still believed global warming was an opinion. That response left the student stunned and set off a larger conversation online about how science should be handled in a classroom.
How the quiz question set off the dispute
DerCatrix said the quiz came from an English composition class focused on distinguishing fact, opinion, and bias. The specific prompt asked whether global warming is a fact, and the student answered yes. When the teacher marked it incorrect, the student initially assumed there had been a mistake in the quiz itself.
After sending an email to ask about the grading, the student said the teacher doubled down. In the Reddit post, DerCatrix wrote that the instructor continued to insist global warming was an opinion and accused the student of using an ad hominem attack. The post presented the exchange as a basic classroom disagreement that quickly became much more complicated.
The student’s account suggests the issue was not just about one answer on one assignment. It became a dispute over whether a widely discussed scientific issue could be treated as a matter of personal belief in an academic setting. That is what made the reaction so surprising to many readers who saw the post.
The teacher’s reply widened the gap
According to DerCatrix, the teacher responded with several paragraphs about “structured debate” and about the student “shutting down conversation before it began” by trying to correct her. The explanation, as the student described it, reframed the exchange as a lesson in discussion rather than a straightforward grading question.
DerCatrix said the response did not resolve anything. Instead, the student told followers on Reddit that they contacted the school and planned to switch teachers. That detail suggested the disagreement had already moved beyond the quiz and into concerns about the class itself.
The post did not identify the college or the instructor by name. It also did not include any formal statement from the school. What it did show was how quickly one disputed answer can become a larger issue when a student believes the grading conflicts with basic scientific understanding.
Reddit users react with confusion and disbelief
Other Reddit users reacted with a mix of confusion, frustration, and speculation. One commenter suggested the quiz maker had either made a mistake or held conspiracy-minded views. Another wondered whether the question might have been meant as a trick, asking if the instructor could have been trying to separate global warming from global climate change.
Some responses took on a sharper tone. One commenter asked what “Red State in the US” the student might be from, implying the teacher’s politics may have played a role. Another user called the situation “more than mildly infuriating,” echoing the mood of the forum where the post appeared.
The online reaction helped turn a classroom disagreement into a widely shared example of how people interpret science, education, and authority. Even without a full record of the class or the teacher’s intent, the post clearly struck a nerve with readers who expected a college-level course to draw a firmer line between opinion and evidence.
NASA’s climate evidence stands in sharp contrast
For context, NASA says there is strong evidence that Earth is warming. On its climate change page, the agency points to global temperature rise, melting ice sheets, and other observations as signs of a warming planet. That scientific framing is directly at odds with the teacher’s alleged view in the Reddit post.
NASA’s explanation matters because it reflects the mainstream scientific consensus described on an official federal science site. The agency’s climate materials are built around measured changes and long-term data, not personal belief. In that light, the quiz answer appears to have touched a very real divide between scientific evidence and subjective opinion.
The student also highlighted that contradiction in the post, arguing that the grading was ironic given the assignment’s purpose. The situation became a case study in what happens when a class intended to teach fact, opinion, and bias appears to blur those categories instead of clarifying them.
Why the story resonated far beyond one classroom
Part of the attention comes from how ordinary the assignment sounded. A quiz about facts and opinions is a standard exercise in many composition classes, and the student’s answer would normally seem straightforward. That is why the reported response felt so unexpected to readers.
The story also taps into a broader concern students often have: whether grades reflect knowledge or an instructor’s personal views. In this case, the student said they believed the answer should have been accepted, then escalated the issue after hearing the teacher’s explanation. That sequence gave the post its momentum.
For many readers, the post was memorable because it mixed a simple school assignment with a topic that is already heavily documented by scientists. The result was a moment that was both frustrating and oddly revealing, showing how much weight a single quiz question can carry when the subject is climate science.
What the student said happened next
DerCatrix said they confronted the teacher directly after the email exchange. In the post, the student wrote that they called the instructor an “anti-science” and “right-wing conspiracy theorist,” and said the teacher placed too much faith in police while blaming victims of police violence. Those comments reflected the student’s anger, though they were not verified by any independent statement from the teacher.
The student’s final update in the post was simple: they said they had spoken with the school and would be changing teachers. That suggests the immediate result was not a resolution on the quiz itself, but a practical step to get out of the disagreement and continue the class elsewhere.
Even so, the story left behind a clear takeaway for readers. A lesson built around identifying facts and opinions became, in the student’s telling, a vivid example of how messy those distinctions can become when a classroom conversation collides with a disputed belief about climate science.
