#3 They'll continue to rebuild the Ptolemaic model of the universe too. It's just the numbers have to be recalculated to account for all the variables that seem to screw up the model's projection.

#4 Less ice, more ice - no problemo. Just tell us what you want. A couple tweaks to the computer model and it's grant money, here we come! (and can we *please* not try to inject actual data into this discussion?)

#5 What is not generally appreciated is how much closer to the equator sea ice is in the Southern Hemisphere.

And the increase in SH sea ice is mostly where its closest to the equator. And incidentally directly south of where I live.

Why does this matter?

In a word, albedo.

We are well past the spring equinox and that new sea ice is reflecting approx 80% of sunlight right back out to space, where previously 80% would have gone into warming the ocean.

This a positive cooling feedback. I'm making no predictions, but keep a close eye on this.

#6 Phil,

doesn't sea ice get less reflective with time?

maybe down to 40% or so depending on the sun angle

#7 lg, not in the southern hemisphere where almost all sea ice is seasonal, and black carbon deposition is minimal.

If the ice gets slushy as it melts, then that will decrease albedo, but I don't know if thats a significant factor. I believe most melt of SH sea ice is from below.
