That would be the black body temperature of an air-less body orbiting

This is the measured average temperature. The about 30 K difference is due to greenhouse gases, i.e. the thermal isolation causes the surface temperature to rise in order to get rid of the same heat as compared with an airless object.

Water vapor is responsible for about 2/3 of the greenhouse effect and the rest, including CO2, is responsible for the rest.

IPCC has created an artificial 'radiative forcing' scale, which only includes greenhouse gases emitted by humans. According to IPCC the CO2 radiative forcing is calculated from the increase of CO2 from 295 to

According to IPCC this relation is logarithmic so the same radiative forcing change is the same for each doubling, so no runaway effect.

Things get absurd with water vapor, since IPCC radiative forcing only caused the extra vapor generating by irrigating and burning fuels containing hydrogen. This is a very small number much less than CO2 numbers.

When one tries to question of the water vapor effects, this is dismissed by IPCC supporters claiming that it is negligible because it is originally so small in IPCC radiative forcing.

of total greenhouse effect (not just IPCC radiative forcing). Any small changes in water vapor contents will have a much larger than small changes in CO2 contents.

The point about water vapour is that it equilibrates within a couple of wee ks.

It's pretty much purely determined by the ocean surface temperatures, and w hat we add just condenses out in the next rain storm.

In that sense it is a pure positive feedback on the CO2 and methane forcing s.

CO2 seems to take about 800 years to equilibrate, and methane oxidises to C O2 and water with a half life of about seven years.

Unless you are Al Gore.

George Bush was wondering which way the cloud from a nucular blast might rotate.

"Molecular comes from molecule, and particular comes from particle, but there is no nucule to support nucular."

You guys do make me laugh!

NT has his own "facts" which aren't accessible to checking.

He likes to think that they are reliable, which is unfortunate, and didn't like it when I compared them with reality and found them wanting.

He seems managed to reinterpret that interaction as me failing to fact-check his output, which is revealing.

Like all James Arthur's simple tests, this is wrong.

Somebody only harping on about costs on the one hand, or benefits on the ot her, is reacting to context.

Objective discussion on merits is an ideal, but all discussions involve dif ferent parties creating the discussion, and some people - like James Arthur - get obsessed about costs, while others are more interested in benefits.

You do need to pay attention to the context.

On climate change, James Arthur sells the denialist line - anthropogenic cl imate change isn't happening, and if were it wouldn't matter, so the Koch b rothers (and other people that James Arthur admires) should be allowed keep on making money out of the business of digging up as much fossil carbon as possible and selling it as fuel.

I'd suggest "I need to know what clueless right-wingers are lying about at the moment".

Donald Trump is a particularly clueless right-winger, and he has always had a peculiar enthusiasm for lying, so fact-checkers do spend a lot of time on his output.

effects system did real time video effects with a Z80B and 768KB of RAM in broadcast quality System M color. The edit controllers for the Sony U-max (3/4") and th e 2" Reel to Reel VTRs used 6502 processors. Those MAC computers were always crap, for real work. The Commod ore Amiga with the external Video Toaster hardware was much better, and cheaper.

nt's gear the comp sci and student library dept/e-mail

Xes from '91 and what

So, the film department got all new equipment, every term? Or were they lucky to get some repairs on 40 yea r old cameras and film processing equipment?

I went to two schools at different times, a small private co llege and a much larger state university a number of years later (2000s.) Because the former was an arts school the AV department tended to not get skimped too much, there was a lab full of fairly recent Macs w hich were underpowered compared to what a movie or T V studio would have at the time, but were not cheap either. So it was somewhere in-between. Not every te rm, but re-fits did happen fairly regularly.

They s tarted moving the Quadras out after I was there a coup le semesters and moving in some Power Macs as it was well-understood by that point the mid-tier Quadra a rchitecture was kind of a dud for real work. situati on was much better on the G3 and G4 class machines.

. It didn't need all night to process video. A pair of U-matics and edit controller were about $5,000, inclu ding two 19 inch monitors. The CATV headend I maintain ed in the early '80s had a system from Panasonic. They pinched pennies tighter than any college.

The IT department at the small school made some questionable decisions from time to time, maybe understandable f or the era when New! Internet! was on the scene, dot com era coming in and everything was in flux. They

were chasing the hottest new stuff hoping to be on the money buut...they spent a bunch of dough on a coupl e BeBoxes for the lab, dual 166 MHz PowerPC processo rs, pretty green light bars on the front that showed

processor usage.

It was a stunningly powerful mach ine by comparison with the other Macs and PCs in the labs and could do some jaw-dropping stuff for the tim e like run 30 standard definition videos at 30 FPS i n windows on the desktop simultaneously. However nob ody really wrote any killer app software for it, at least nothing anyone knew how to use. As I recall th ey mostly sat unused blinking away on server-duty most of the time.

d for Email servers? The secretaries had nice new comp uters at Microdyne, but Production was still using mac hines back to the XT. Some, because they were the only ones available, and others to support programming of obsolete PLA and very early EPROMS. I had to laugh at the Y2K 'expert' hired to make sure that every system was compatible. He was complaining that he couldn't ge t into the BIOS of a Zenith computer. I told him that it was a dedicated XT, with no real time clock. I had to laugh even harder when he said that we would have a ll new computers within a month. He was the same fool who ;upgraded' a Windows 2.0 system too Win 95 without asking. He wiped out all of the test software that wo uld only run under 2.0, without making a backup. It to ok me almost a full week to rebuild the files from mul tiple, partial backups. The test software was written by Scientific-Atlanta, but they had disposed of all tr aces of the automated test system after they lost a pa tent infringement lawsuit, and contracted with us to b uild the est of the equipment they had contracts for. The settlement inculded them giving us all files, and the test system.

There were lots of 40 year old 8mm cameras and black and white still cameras of the same vintage still around even circa 1996. A lot of AV and film professors preferred students start out that way and a lot of students preferred it, too. Y'know, "artistic."

Art students as a general rule aren't gear-heads and aren't big into keeping up much with the latest stuff. It wasn't uncommon for incoming freshmen to bring Mac SEs from circa 1986 from home for use as their dorm-room computer. in 1998.

A big portion of a fine arts "education" in the computer-age is getting students accustomed to using the software that people in art production, TV, film, and broadcast industry tend to use a lot at the time.

Not every student in their job (hopefully not serving fries) will get to have a Video Toaster setup at their disposal but just like in EE there are some standard software tools, often on Mac, that were and still are common throughout the industry: Photoshop, Macromedia (now Adobe) Director, 3D Studio, Maya, POV Ray, Premier, etc.

So, your 'nightmare' prominently features a vice president from an earlier century?

Not Spiro Agnew or Dan Quayle !? That's just SO WEIRD!

Spiro Agnew, lol! That's just a funny name. A 'p', a 'g' and a 'w'. Very funny!!!

There's nothing weird about it. Al Gore got part of a Nobel Peace prize for his work on popularising anthropogenic climate change.

John Larkin thinks that climate change isn't real, and that everything that Al Gore talks about is a scam designed to extract money from tax-payers - in other words John is a gullible sucker for climate change denial propaganda.

It's a very unrealistic view of Al Gore, but John Larkin has some deeply unrealistic ideas.

That's reading a lot into a cover design.

The artists that do the work aren't actually climate experts - the commission is to design something visually arresting, as opposed to creating a graphic illustration of some scientific point.

Even Alben Barkley makes a better nightmare character than the distinguished Al Gore. A criminal (Spiro) or absurdist (Dan) would spice up those dull dreams.

For John Larkin, Al Gore is a criminal - or at least a con-artist - because he takes anthropogenic global warming seriously.

John Larkin has been conned by the climate change denialist propaganda machine and they have instilled some bizarre misapprehensions into whatever it is that John Larkin uses in place of a brain.

John Larkin did do a science degree, but at Tulane, and he didn't pay much attention to the science as such. Al Gore as an undergraduate got lectures from Roger Revelle, and does seem to have been paying attention.
