No sea level increase last 100 years

So facts to back that up. History does not support that

The facts you've been talking about support it. The Earth cycles between warm and cold periods, and has for millions of years. Of course, there will be a cooling trend in another few thousand years. Why would those cycles stop?

Even one of your skeptics agrees that these cycles take thousands of years, not hundreds.
CO2 vs Temperature: Last 400,000 years

This isn't a point of discussion for anyone, ptif. The cycles are very long-term.

He says we are do for another ice age

Historically, glacial cycles of about 100,000 years are interupted by brief warm interglacial periods-- like the one we enjoy today. Changes in both temperatures and CO2 are considerable and generally synchronized, according to data analysis from ice and air samples collected over the last half century from permanent glaciers in Antarctica and other places. Interglacial periods of 15,000- 20,000 years provide a brief respite from the normal state of our natural world-- an Ice Age Climate. Our present interglacial vacation from the last Ice Age began about 18,000 years ago.

You're changing the subject. The point is that these periods aren't centuries. Now that some skeptic says it, you suddenly believe it when before it was just more propaganda.

And if we're due for another ice age, why are we warming up?

The warming is slowing and very slow. It is not the doom and gloom the GW propagandist claim it is

Last I checked, this is the common theory:

1. Warm water in the Gulf Stream gets even warmer.
2. The Mediterranean gets warmer (it's fed by the gulf stream).
3. The cold, deep water leaving the Med is much less and the Atlantic Deep current will be little.
4. The circumpolar current, the only continuous current, will not be fed enough by the atlantic deep and will stop.
5. Ice age, the graph angles back down.

So when does this happen and what evidence can you provide to support that?
And what causes the warming that leads to this situation?

Last I heard, the main ocean currents hadn't even slowed down yet.
