had to delete this post. But it may still show up in apps and be confusing.

Note to self: Threaded posts are normally replies 😅

Which path do you believe we're on?

Best estimate of global warming:
SSP1-1.9   1.4 °C
SSP1-2.6   1.8 °C
SSP2-4.5   2.7 °C

Range:
SSP1-1.9   (1.0 °C to 1.8 °C)
SSP1-2.6   (1.3 °C to 2.4 °C)
SSP2-4.5   (2.1 °C to 3.5 °C)

I believe we’re on path SSP1-2.6  –  not good.
The world could be better than 1-1.9  –  how?

The light blue line could go down to minus 40 by year 2100
- if politicians and companies took serious action for CO2 removals.

- - - - -
The numbers (1.9 etc.) are not temperature, they’re radiative forcing.

New IPCC ClimateReport to be published on Monday

Maybe Mastodon should consider renaming the local timeline?

▫️ Community timeline
▫️ Server timeline
▫️ ?

Wow, they've been working on some cool stuff in Scotland 😃

Maybe Project Gutenberg will come back one day? 😭
The printing revolution literally started here and now all the books are gone. 😦

Project Gutenberg felt bullied (their own words).

"...the German Court has overstepped its jurisdiction, and allowed the world's largest publishing group to bully Project Gutenberg for these 18 books, there is every reason to think that this will keep happening. There are thousands of eBooks in the Project Gutenberg collection that could be subject to similar over-reaching and illigitimate actions."

Project Gutenberg have blocked access to all 65 000 books for people in Germany.

A German copyright holder wanted them to remove 18 books. The books are still copyright in Germany but already public domain in USA.

A court ordered that it was sufficient to block access to the 18 book for Germans.

Gutenberg blocked all 65 000 books.

I question if we should allow space tourism at all at this point in history.

At a minimum we should demand that the CO2e emissions are captured before each trip.

Those companies should be net zero and not by planting trees, by direct air capture using technology.

I would go for A. They didn't fly an airplane to the moon. Launching yourself 100 km above ground and falling straight down again is a bit of an adventure.

But, If I could choose to stay on earth I would probably do that.

Unless, it was two weeks at the moon including a weekend trip to weightlessness in a freshly built space station. I would definitely do that.

That's the space tourism I want.*

* With renewable non combustible fuels and with a healthy sustainable earth and society below

If you *must* travel to space. Which trip do you choose? Why?

A: Sitting inside a capsule on top of a rocket. Capsule disconnect from rocket. The capsule lands with a parachute. (Bezos)

B: Sitting in a small airplane connected to a big airplane. Small airplane boost itself out the last little bit into 'space'. Airplanes lands separately (Branson)

Space tourism seems to be the next thing? But is it worth it?

I worry that it may be bad for the climate.

Also, why is it only ten minutes? Where's the hotel?
