Good try, but no cigar. Nobody is claiming that there will be a runaway greenhouse effect. The only people who claim that the IPCC are saying that, are the denialists.
Some astronomers have speculated that in a couple of billion years the Earth could develop a runaway greenhouse effect, but it certainly has nothing to do with climatology.
Ducking for cover again.
Its only going to get tuffer for the alarmists as one by one their hypothesis is put to shame.
It never was a hypothesis.

You're not reading the replies. I think I'll stop trying. This has all been explained to you - and sea levels are on a rising trend.

No it isn't. It's not crucial to anything. A hot spot in the tropopause is a result of any forcing resulting in warming - direct solar, increased CO2, anything.

Now that it cant be found.....???
Its in one of the AR papers maybe one day i'll dig it but not tonight.
The only hot air is that coming from Dave Evans, Joanne Nova's other half - the self styled rocket scientist and quack.

Summary
Each cause of global warming heats up the atmosphere in a distinctive pattern—its ―signature‖. According to IPPC climate theory, the signature of carbon emissions and the signature of warming due to all causes during the recent global warming both include a prominent ―hotspot‖ at about 10 – 12 km in the air over the tropics.
To me, Dave's argument (we are not worthy) is:
1. The hot spot that they can't find (actually they can, once they correct for noise) can be caused by
any kind of warming. (Dave said it himself- see the highlighted text).
2. Because the hot spot isn't there (of course we know otherwise), it must be due to a failure of CO2 (as opposed to
any cause) to cause warming.
Meanwhile there is evidence of global warming.
Can you see the logical fallacy? Think about it. Who is he trying to kid? Joanne Nova?
