Editing Talk:1606: Five-Day Forecast

As far as I can figure out, -452 F is something like 4 K, which seems a bit too warm (above OTL microwave background). It probably should be -456 in the next-to-last row and -458 in the last row (-459 for the last column). --[[Special:Contributions/141.101.81.76|141.101.81.76]] 12:58, 20 November 2015 (UTC)

: Inside a galaxy, it presumably ''is'' a bit warmer than CMB, since there are stars around to heat the {{w|interstellar medium}} a little. --[[User:Aaron of Mpls|Aaron of Mpls]] ([[User talk:Aaron of Mpls|talk]]) 05:40, 22 November 2015 (UTC)

Thanks for the conversions to degrees C as being a 58 year old Brit I have never understood degrees F (I know what they are just I have no idea whether 60F is cold, cool or comfortable). I have always used 5, 10 and 21, Winter, Spring and Summer sun - well works for Middle Brittan) [[User:RIIW - Ponder it|RIIW - Ponder it]] ([[User talk:RIIW - Ponder it|talk]]) 19:09, 20 November 2015 (UTC)

There will be ambient starlight in addition to the 2.7K background which should raise the temperature slightly. However, the 2.7K background will also redshift to a lower temperature as time goes on: T propto 1/a where a is the scale factor of the Universe. Would be a good assignment for a cosmology class.

Aha, what will last longer than stars etc is the silly Fahrenheits.

There  are five columns. Either the first column is "today" and one should not speak of predictions after five (m/b/trillion) years (as is currently the case a couple of times), or the first column is "tomorrow (etc.)" and then the prediction of "A bright yellow sun; 38°F" for one trillion years would be very strange.

If the "red giant" temperature measures the sun's core, how do you explain the last panels showing decidedly non-white-dwarf temperatures? --[[Special:Contributions/199.27.130.234|199.27.130.234]] 03:48, 21 November 2015 (UTC)

Regarding the 5-year-predicion: It seems to me that the temperature is in average rising a bit across the year, maybe a reference to the slow process of global warming? This would not be the first time, there are even whole comics just about global warming, especially about the noticeable speed and the "in average"-importance (e.g. 1379, 1321)

-:: If Randall is going to use Farenheit why don't we stick with Rankine, thus -452 F works out at about 8 R? (Saves all the messing about with multiplication and division) [[Special:Contributions/162.158.34.147|162.158.34.147]] 13:15, 23 November 2015 (UTC)

-: FYI 60 degrees F outside is quite pleasant, a little cool, but inside your feet get cold. 15.5 degrees C [[User:NotLock|NotLock]] ([[User talk:NotLock|talk]]) 09:12, 22 November 2015 (UTC)

-:: As a younger Brit (56) I grew up with Farenheit, I'm not sure where in the UK our 58-year old grew up, but I don't remember a concerted effort to use SI units until the mid seventies. For me it's the other way 'round: 60F sort of OK as long as it isn't windy, 70F quite warm, 80F Phew! What a scorcher! All the centigrade equivalents are just too small! :) [[Special:Contributions/162.158.34.147|162.158.34.147]] 13:15, 23 November 2015 (UTC)

-: I don't believe so. Five years is probably too short a period for discussing global warming. Limit it to a single place and even more so. Limit it to a sample of one day per year, and I believe you can't bother looking at the p-values. --[[User:Ahyangyi|Ahyangyi]] ([[User talk:Ahyangyi|talk]]) 15:56, 29 March 2016 (UTC)
