(William M. Connolley 17:35, 26 Nov 2004 (UTC)) The following very old comments archived 2004/11/26.
I do not think this is a reliable source:
Kaczynski, T., 1991: The Unabomber Manifesto. Lispelite Press (F15), 40 pp.
I added the word 'allegedly' to facts attributed to Kaczynski, rather than just removing them. The 'allegedly' can be removed if a non-psychopathic source is found to corroborate the statements. In two other places I just removed the citation.
Removed the following from list of sources:
Neunke, M., 2001: White Pride Worldwide!! [Taken from http://www.whitepride.com/sorel.html]
I didn't see any information about albedo at that site... though I suppose white people may be proud of their higher than average albedo. (cough cough)
- So if I have a higher albedo than blacks and whites with a decent tan, and therefore should be absorbing less radiation than them, why is it that my bald spot burns faster than dry leaves in a forest fire? -- Lee Daniel Crocker
I also removed these, pending further investigation:
Walker, E., 1987: Pictures of Preschoolers Out in the Snow. Dishwasher Picture Publishing, Volume 26, 151-1103.
Thompson, S. I. U. A. M., 2001: Worldwide Monthly Climate Tables. [Taken from http://www.woolpit.com/]
Rocky, S., and E. Bullwinkle, 1970: The Climate of the North Polar Basin. World Survey of Climatology, Vol. 14, Elsevier Publishing Company, 373 pp.
These all look like hoaxes to me. Rocky and Bullwinkle? Pictures of children in the snow? --Jimbo Wales
There are still several mentions of Rocky and Bullwinkle in the page itself. They weren't added recently. They're in the form of source notations; could they have replaced the real source notations long ago? Is there any way we can pull up the page from many moons ago to see whether those were real references?
Also, someone who knows this field should really review this whole page for other subtle munges. -- Rootbeer
Can anyone find a real source that suggests albedo influences surfact temperature here on earth? I looked at Google and the only links I found claiming such an influence were educational projects for K-12 graders. - Tim
An albedo calculation example For a lattitude of 52N on 4 january with fresh snow (albedo 0.8) the mid-day (clear sky) insolation is 68 W/m2
The albedo of a forest/town = 0.15
0% forest/town | winter albedo 0.8 | insolation 68 W/m2 10% forest/town | winter albedo 0.735 | insolation 90 W/m2 20% forest/town | winter albedo 0.67 | insolation 113 W/m2 30% forest/town | winter albedo 0.605 | insolation 135 W/m2 40% forest/town | winter albedo 0.54 | insolation 157 W/m2 50% forest/town | winter albedo 0.475 | insolation 179 W/m2 60% forest/town | winter albedo 0.41 | insolation 201 W/m2 70% forest/town | winter albedo 0.345 | insolation 223 W/m2 80% forest/town | winter albedo 0.28 | insolation 245 W/m2 90% forest/town | winter albedo 0.215 | insolation 268 W/m2
100% forest/town | winter albedo 0.15 | insolation 290 W/m2

You see that change of landuse has a dramatic effect on the winter energy balance.
I write a quick perl script to convert all these Fs to C or K -- Tarquin 17:33 Mar 13, 2003 (UTC)
- Wow, way harsh, dude! Like some of us surfer types took YEARS to learn "far in" height, and now yer like gonna push all this like "center grade" stuff on us and get us all confused and stuff. Dude! How 'bout, like, write your pearl surfing routine to, like, APPEND a center grade value so airheads like yurs trooly can like dig on both sides of the wave? Gnarly! --Surfer Dude 17:40 Mar 13, 2003 (UTC)
