Phew - what a scorcher (tm) !

That would be a balmy 97F in Tucson, AZ, USA.

So to summarize, global warming is going to bring on an ice age. I get it.

But wait a minute... I thought all of these low-lying countries were going to be under water, so is it ice or water and will Tucson have drought or excessive rain?

If low-lying ground is flooded the reflectivity of the earth increases which reduces the incoming energy, cooling it again.

So you get a see-saw of hot times followed by ice ages.

Boston going under will be beneficial... it'll hide all the "Big Dig" crookedness from the public eye ;-)

What we need is a national law like we have here in Arizona... you can't build on a flood plain. Thus when Boston and portions of N'Orleans go under we won't have any more whining ;-)

This is loop dynamics by inspection, which sometimes works but usually doesn't. You could just as well conjectute a nice steady equilibrium.

I thinking I'm coming around. That new water that's formed has higher reflectivity than the ice that just melted and this makes the planet colder. Got it. Thanks.

So what's the period of the oscillation? And why?

John

The water also occupies more area than the ice did. The key word is albedo.

Graham

Why oscillation ? Because of a lag effect AIUI. And it's not as simple as that anyway since ordinary year to year fluctuations cause an added 'noise' contribution.

So, you're saying the earth's filter caps have a high ESR and aren't filtering out the thermal noise?

That's pretty much it actually.

As I suggested, look at the water. If it's clear and has no odor after the corn is cooked, it removed nothing. If it removes anything, it will be mostly soluble sugars. I've never cooked corn and got clear water afterwards.

We're 35 minutes from Half Moon Bay and less than 2 hours from the Central Valley, the most productive farmland in the world. The corn at the farmer's market was trucked into the city that same morning, by the people who are selling it. In mid to late summer here, the fruits and veggies are cheap and astonishingly tasty.

John

See my other post.

Do they grow corn in Phoenix?

But you don't have AJ's ;-)

Sometimes we shuck it, wrap in foil, and barbeque. It scorches some of the kernals, which is interesting for a change.

The sweetest corn we get here is the white stuff, but I prefer the yellow, as it has more cornish flavor.

John

I have some Cornish clotted cream in the fridge. ;~)

Graham

You regularly buy fresh fruit and veg there ? How typical is that of the average US citizen ?

Graham

Again, loop dynamics by inspection. It looks to me that the earth's thermal system is heavily damped, a very sloppy and sluggish loop that has good self-righting effects. It's forced mostly by external effects of orbit and solar output, and the occasional catastrophic event. Human CO2 may well cause some warming, but there's no reason to expect it will change some loop gain that leads to oscillation. That's just environmentalist-fatalist-Gorean wishful thinking.

There are "Farmer's Markets" and "Produce Stands" all over the country. It just depends on whether someone wants to take the time to shop there. Some even grow fresh vegetables and herbs as a hobby. I just picked my first fresh tomatoes of the season a couple days ago.
