The subtitles are “Famine, economic collapse, a sun that cooks us: What climate change could wreak, sooner than you think”, and “When will the planet be too hot for humans? Much, much sooner than you think”.
The author thinks that today’s teenagers will see the catastrophic collapse.

They don’t survive long enough to have a good statistical chance of finding one another across light years. In the video above, Harvard professor David Kipping notes that methane degrades quickly and says that Wallace could be overstating the methane risk.
