Science basics-thread?
« on: July 04, 2019, 08:31:19 AM »
As the forum has grown to a quite large place, it might be useful to have a science basics thread. Kind of 'RTFM' or 'FAQ' of old. Sure, there are some details to be discussed in most scientific issues like the one with the band broadening questioned by Gerlich & Tschesuner some years back which was properly refuted by better men than me. But surely, there are some common questions and misunderstanindings that take up a whole lotta space elsewhere.

Like a list of simple facts like the one I recently had to check, methane is indeed lighter than air and thus accumulates to TOA in the tropics where massive sprite lightning may destroy some of it...

Or the one I messed up with the MJO confusing the segments on the standard plot.

Like some regular absorption diagrams for common gases. Or a list of heats of fusion and vaporization and the associated temperatutes.

Well, maybe this is a stupid idea, referring to skeptical science is likely always a good choice. But still, should there f.e. be some basic explanation of entropy, blackbody radiation, entalphy, well energy diagrams of chemical reactions and such on a site that mainly deals with ice on natural environments and social cost of carbon (for a lack of a better phrase)? Once there'd be enough info the thread should be locked down.

Probably, a wiki would be a much more suitable structure for that.

Yes, cross-linking several science-articles in a way relevant to climate science would probably be best. There's of course
Spencer Weart's Discovery of GW which does this to some extent, he though left the 'anthropogenic' bit out of the header.

That is a great resource. Back then i really appreciated his explanation of the simple old single column models.

It would be cool if he could do an addendum on more recent model developments and also paleo stuff (all ask him what it costs as soon as i win the lottery).

Not sure how useful a basic science thread is because there about as many levels of basic as there are people.

I suggest just taking the questions as and when they come. Mostly they should pop up in a specific context and might be best answered there (unless they are the threads we would like clutterfree).

I recently reposted Water Vapour Feedback or Forcing? from RealClimate which also has good basic stuff (and more) ... did not think i would repost that 2005 golden oldie but it was still useful.

I think it works in reverse. If the basic questions pop up they will be answered (and as we saw recently then it really depends on what the person asking the question does with the first two links).

Really simple stuff would be just duplicating wikipedia anyway and we can just link that.

Seems like a good place for this:

A Review of Bob Henson’s Awesome Book: The Thinking Person’s Guide to Climate Change
by Weather Underground's Jeff Masters - 2019 Nov. 27
Quote
This is the fifth version of Bob’s comprehensive climate change book, which originally appeared as the "Rough Guide to Climate Change" back in 2006 (see my 2008 review). He organizes the new book into five sections:

The basics--global warming in a nutshell
The symptoms--what's happening now, and what might happen in the future
The science--how we know what we know about climate change
Debates & solutions--from spats and spin to saving the planet
What can you do?--reducing your footprint and working for action
...
Much more at the WU link.

I have a folder called basic data and arithmetic. There I keep stuff such as
- the data and arithmetic to show how the oceans as a heat sink have a capacity more than 1,000 times that of the atmosphere,
- conversion tables (e.g.s energy as Kwh, BTU, CO2 as ppm & GT),
- area of land & oceans at various levels of detail,
- basic physics (e.g. explanation of how a greenhouse gas heats up the atmosphere)

I only store in that folder that which will not change. Climate science is changing so fast that as soon as a conventional wisdom is established it gets demolished. Read recent(ish) posts by AbruptSLR how the ECS values in the new CMIP6 models are so much higher than those used in the CMIP5 cycle.

I can see this thread as a useful place to put basic data, but not for where there is still debate on AGW - how much, when, what and where - i.e. almost everything.

As far as basic science leading to better technology let me link back to morganism's post at
https://forum.arctic-sea-ice.net/index.php/topic,480.msg244268.html#msg244268


What is announce are new synthetic clathrates that can be Semiconductors or/and Superconductors at high temperatures!


DARPA and the DOE appear to have this covered, but this was no Manhattan project & I assume the world is already hard at work on this.


If it's real (and there is no reason to suspect that it isn't) it canwill change everything we thought we knew of the limits of electronic devices from solar cells, to computers, to batteries, to ???????.


It's as if transistors were new on the world stage.
A Gigantic Black Swan has touched down.


Before Clathrates / After Clathrates


It's that big - I think.

I don't know if this is the right thread for this web, happy to move it somewhere else.

NASA free software. More than 600 programs for very different subjects. Have a look!
