You’re still collapsing three different things into one bucket: individual scientists speaking in public, activists and politicians amplifying the most dramatic framing, and the actual scientific literature.
Yes, some scientists have made alarmist or overstated claims in interviews, talks, or on social media. Scientists are humans, not priesthoods. That doesn’t magically convert those statements into “the science.” Science is what survives peer review, replication, and synthesis in assessments like the IPCC, not what one person says on Twitter or at a rally.
You’re arguing from cherry picked spokespeople, not from the body of evidence. That’s media logic, not scientific logic.
