I recall the oceans absorb solar heat, so to cool the earth we could
dump plane loads of a floating reflective material onto the oceans.
Maybe Christmas tree foil or that glitter stuff kids use with
Elmer's glue.



Nah; a better solution would be to put something big between the
Earth and the sun if it's too hot, a big mirror or a bunch of little
ones somewhere up there if it's too cool.

The technology and materials exist; cost is the biggie.


You are kidding, right?


Absolutely not at all.

And it actually is on topic for the newsgroup ;-)

See http://en.wikipedia.org/wiki/Solar_sail


Programmers call that "vapor ware".

And no, we do NOT have the technology for anything like that.

HEck, we don't even have the technology to go to the moon at this time.
