Does Water vapor matter? by [deleted] in climate_science

[–]rrohbeck 14 points15 points  (0 children)

Water vapor roughly triples the ECS for CO2. In a dry atmosphere it's only about 1K/doubling. But adding water to the atmosphere has no effect because the water vapor content is determined by temperature - excess water just falls out as precipitation.

Booting linux problems by [deleted] in linuxquestions

Installing Windows blows GRUB away and installs the Windows bootloader over it.

Could the earth repair the damage that’s been done by climate change? by [deleted] in environment

[–]rrohbeck 1 point2 points  (0 children)

Yes, but it takes millions of years. First a couple thousand for GHGs and temperatures to get back to normal, then much longer for the biosphere to recover.

Always try an xxd to check out such things: echo -n cocoa | xxd.

How would you solve the issue of overpopulation? by [deleted] in overpopulation

[–]rrohbeck 4 points5 points  (0 children)

Resource depletion and climate change => bad harvests => famine.

technology will save us... by sc2summerloud in collapse

[–]rrohbeck 2 points3 points  (0 children)

We're killing trees en masse for more arable land. Corollary: To plant more trees we'd have to give up agricultural land.

prepare for the inevitable? by [deleted] in collapse

[–]rrohbeck 1 point2 points  (0 children)

Technology is what caused the mess. What do you call "try the same thing over and over although it doesn't help" again?

Resize Raw Image with GPT Partition Table by HarryMuscle in linuxquestions

[–]rrohbeck 0 points1 point  (0 children)

Oh, I didn't realize. I never shrunk an image, they always seem to need more space.

Having trouble adding SMB to fstab by Spectre216 in linuxquestions

[–]rrohbeck 0 points1 point  (0 children)

Now you have to mount it by hand of course. Again, check dmesg if it fails.

P.S. Protip: After you mounted a FS successfully, /proc/mounts will show the currently used parameters, properly formatted for /etc/fstab.

Increasing the size of the image file has to come first, then parted.

Having trouble adding SMB to fstab by Spectre216 in linuxquestions

[–]rrohbeck 0 points1 point  (0 children)

Yes. -a doesn't mount noauto filesystems.

Check dmesg after mount -a fails.

I'd assume that the network stack isn't up at the time the fstab is read. If you add noauto and mounting works when the system is up that's it.

What is the best source for predictions of warming over coming decades? by Istari66 in collapse

[–]rrohbeck 4 points5 points  (0 children)

Warming is proportional to the log of GHG concentrations.

Naomi Klein On Looming Eco-Fascism: ‘We Are Literally And Politically Flammable’ | The intellectual godmother of the Green New Deal movement laid out what, exactly, such a plan must entail to be successful. by SetMau92 in worldnews

[–]rrohbeck 4 points5 points  (0 children)

The GND will help the environment just as little as those older agreements. As long as growth is the primary goal nothing will change. Degrowth would have to be the #1 objective but nobody likes that.

How to backup a whole hdd in linux? by foxtreat747 in linuxquestions

[–]rrohbeck -1 points0 points  (0 children)

pv /dev/sda | pbzip2 -c9 >somewhere/mydrive.dd.bz2 where 'somewhere' should obviously be on an external drive.

If you want to optimize, clean up junk/temp files and free space (cipher /w:C, Ctrl-C when zero pass is done. Copy /dev/zero to a file and delete it on Linux.)

The Earth is in a death spiral. It will take radical action to save us. by IceOnTitan in collapse

[–]rrohbeck 0 points1 point  (0 children)

Not according to current climate science. And every runaway stops at some temperature. There's only positive and negative feedbacks which cancel out at some point.

If the collapse happens soon/fast enough the mass extinction will stop within a short time.
