What Earth’s Final Biosphere Will Look Like | Jacob Haqq Misra
John Michael Godier usually points Event Horizon outward, toward strange stars and stranger galaxies. His one new episode turns the telescope around. In "What Earth's Final Biosphere Will Look Like," he sits down with Jacob Haqq-Misra, the astrobiologist at Blue Marble Space Institute of Science, to ask what is left of life here as the Sun slowly brightens and the planet runs short of carbon dioxide and, eventually, water.
The description points to Project Janus, Blue Marble's study of ten possible versions of Earth and the solar system a thousand years from now, scenarios the institute also treats as clues for spotting technology on other worlds.
The comment section went straight to the hard limits. Several viewers push back on the idea that an evaporated ocean ends life, pointing to microbes living in the pores of crustal rock, and others argue that photosynthesis itself might adapt rather than simply stop. One commenter, an Arizona resident and veteran of Iraqi summers, weighs in on how much heat people can take. The lighter end has HG Wells' giant crabs, a Futurama flashback and a toast to the cactuses.
Within nine hours it was already moving at the pace of a whole ordinary day on the channel. Behind it, Devesh Nandal's two visits, on the weirdest stars and on JWST's little red dots, keep drawing a steady trickle. Overall the channel ran a touch below its usual pace and held at 334,000 subscribers. Among the science channels nearest its size, Astrum Extra is having the big week, while Bizarre Beasts is well above its own norm.

That Europan bottle of water gonna be expensive
@CORYJOHNMSee it on YouTubeno i appreciate his co2 explanation, he didnt rant or go on, i appreciated his nuance
@liberatedcollective2124See it on YouTubeI think it also bears mentioning that the end of photosynthesis as we know it doesn't /necessarily/ mean the end of complex primary production. Under mounting selective pressure, photosynthesis itself could change to last longer, plants could adapt to survive for longer in ways that don't necessarily depend on photosynthesis, or other things could potentially fill the primary production niche if plants fail in it.
@68plusorminus1See it on YouTube18:00 "when you evaporate the ocean that's a hard limit on life"
Not true. There is a tremendous amount of (mostly single-celled) organisms that survive within the crust of the earth itself down to an as yet undetermined depth which survive on water in the porous structures of crustal rock. their access to water is often extremely limited and so they have very slow metabolisms, but oceanic water is most definitely not a limit on terrestrial life. only the melting and evaporation of the earth's crust from an expanding sun will do these guys in.@b.griffin317See it on YouTube

A viewer recalls the giant crabs of a far-future dying Earth in which H. G. Wells novel?
In The Time Machine (1895), the Traveller journeys far into the future and sees giant crab-like creatures on a beach under a dim red sun.
