From a strict contribution to global warming standpoint, how to decide how dark of exterior home paint should be used?
At the extremely hot end (e.g. Phoenix AZ), there might be a clear answer, but what about mid-continent where we need significant amounts of both heating & cooling?
I think coming up with anything other than a guess would require a lot of calculations based on a lot of variables, such as latitude (sun angles) and heating efficiency.

“Studies in recent years have shown that the Arctic is warming much more rapidly than the rest of the planet due to feedback from the loss of sea ice
—so it is not surprising that we are seeing these all-time record temperatures at high latitudes,”
says independent meteorologist Alan Gerard.
It’s a dangerous feedback loop:
as sea ice melts, the Arctic reflects less sunlight,
and the ocean absorbs more heat.
This generates even more sea ice loss.
The …

It’s 90 degrees in the Arctic right now
The Arctic is heating faster than the rest of the planet. New data illustrate how dire that is

internet_top_pop: Internet topology (PoP level) (1969-2012)
Assorted snapshots of internet graph at the Point of Presence (PoP) level (which lies between the IP and AS levels), collected from around the world and at various times. The earliest snapshots are for ARPANET (1969-1972), with a few more from pre-2000. Most are from 2006 onward. Metadata include link type or speed, longitudes, and latitudes of nodes, URL, and date of record.
This network has 110 nodes and 158 edges.

Amazon says Leo reached 396 satellites in low-Earth orbit following a recent launch, which is "enough to support continuous service across initial latitudes" (Thomas Ricker/The Verge)

Amazon has enough satellites to launch its Starlink competitor
Amazon Leo has just 396 satellites in orbit, compared to Starlink’s bumpy “better than nothing” beta which launched with about 900.
