Abraham explains how he got involved in rebutting Monckton in this article in The Guardian. In the article he also demonstrates Monckton is misquoting scientists and misinterpreting science over and over and over again. An example :
For instance, Monckton's claims that "Arctic sea ice is fine, steady for a decade" made reference to Alaskan research group (IARC).The original version of Abraham’s full rebuttal can be found here, but it’s also available on Youtube, the first part is given below. The list with references used can be found here
I wrote to members of IARC and asked whether this was true. Both their chief scientist and director confirmed that Monckton was mistaken.
They also pointed me to the National Snow and Ice Data Centre (NSIDC) for a second opinion.
A scientist there confirmed Monckton's error, as did Dr Ola Johannessen, whose work has shown ice loss in Greenland (Monckton reported that Johannessen's work showed that Greenland "was just fine".)
Next, I investigated Monckton's claim that the medieval period was warmer than today. Monckton showed a slide featuring nine researchers' works which, he claimed, proved that today's warming is not unusual – it was hotter in the past.
I wrote to these authors and I read their papers. It turned out that none of the authors or papers made the claims that Monckton attributed to them. This pattern of misinterpretation was becoming chronic.
Chris Monckton wrote this reply which above anything else is embarrassing. It takes his Lordship exactly five words to drop the word “Goebbelian” and it only goes downwards further on, an example :
So unusual is this attempt actually to meet us in argument, and so venomously ad hominem are Abraham’s artful puerilities, delivered in a nasal and irritatingly matey tone (at least we are spared his face — he looks like an overcooked prawn)John Abraham gave this polite response to Monckton’s bewildering rant.
