Great Debate Part III & IV – Glikson accidentally vindicates the skeptics!

UPDATED Part IV: Andrew Glikson replies below.

I am impressed that Glikson replied politely, rose above any ad hominem or authority based arguments, and focused on the science and the evidence. This kind of exchange is exceedingly rare, and it made it well worth continuing. Links to Part I and II are at the end. Round 4 was copied from comments up to the post.

Depending on flawed models

For a sentence, I almost think Dr Glikson gets it. Yes, it’s a quantitative question: Will we warm by half a measly degree or 3.5 degrees? It’s not about the direct CO2 effect (all of one paltry degree by itself), it’s the feedbacks—the humidity, clouds, lapse rates and other factors that amplify (or not) the initial minor effect of carbon.

Decades ago, the catastrophe-crowd made guesses about the feedbacks—but they were wrong. Instead of amplifying carbon’s effect two-fold (or more!) the feedbacks dampen it.

Dr Glikson has no reply. He makes no comment at all about Lindzen [1], Spencer[2] or Douglass[3] and their three peer reviewed, independent, empirical papers showing that the climate models are exaggerating the warming by […]
