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 ;-)
