If someone asked me to summarize what you just said, I would say the scientist described a “tipping point” as inaccurate and irresponsible.

Inaccurate because she said it’s claiming something that isn’t true.

And irresponsible because it will sap the political will to do something about it.

True, though without greater specificity I, at least, interpreted the original comment to mean that the scientist believed the phrase "tipping point" was overly alarmist.
