Saving Earth's Biosphere from the Brightening Sun with R.J. Graham

When will Earth's macroscopic land plants face extinction due to CO2 starvation, and could interactions between climate, plant productivity, and weathering extend their survival until extreme temperatures ultimately end photosynthesis?

I stayed up especially to catch this. Thank you JMG+ for all your presentations and content. I bloody love it.

Really interesting episode. Didn't know about the plant-fungus-virus symbiosis and CAM photosynthesis. Glad to hear scientists saving the biosphere for another few million years.

The virus / fungus / plant turducken of heat superpower got me wondering about how we're trying to grow plants in Martian conditions - should we place (or are we already placing) some viruses and fungi from soils of earthly places, as similar as is possible to Martian conditions?
Separately, should the seed bank in Norway also begin keeping soil samples?

I really liked how RJ articulated his ideas! I would be glad if he was a guest again.

Thanks for the great meaty material. This really reminds one that life is not about absolutes, but about margins and mediations. At this temperature, these cycles are more relevant, and in these conditions, these other ones dominate. Life isn't about building an empire for today, it's about surfing a wave across time :)

Very interesting, and a great guest.

Thank you John and RJ !! 🚀🚀

11:00 I've heard one reason you can't grow plants from far away, is the soil lacks the fungal symbiont.

Cacti can get water from the air. So a desert planet may not be a problem. The water ends up in the atmosphere.

Thanks for all the work and dedication to the truth.

A heavy enough 'mass driver', in a certain orbit, can be used, to change the Earth's orbit, and keep the Earth just far enough, in a slowly expanding orbit, to maintain the current temperature. The habitable zone already, shifts outward, aproximately, 1 meter per year. ... Obviously this idea needs more details, and modifications.

It was a good point about "too much" water.. if a planet that is an otherwise Earth twin has oceans 100s of miles deep- the pressure at ocean bottom would shut off geothermal and it would be extreme at the surface

This guy was really good in the zombieland movies.

Top 10 guest..great episode thanks both!

[DeepakKumar-tvdc]

Really good show tnite, appreciate it!

[draketungsten]

Man, it's next Thursday? I did not have next Thursday on my bingo card for this year!

[Faidrs]

Very good episode, but I felt so sorry for R.J. who sounded terrified and insecure, and apologized a lot even though he did so great.

Solar shades and moving the planet’s orbit

[generalnawaki]

Mars being habitable is not about it not getting enough light, its about it not having a strong enough magnetosphere to to protect its atmosphere from the already strong solar wind.

Have to say I'm feeling very vestive with all this constant content dropping keep up the good work team❤❤❤❤❤

The place for the long answers indeed👍
