Sorry, that chart is from the doc, 'the great global warming swindle', its a Tim Ball slide from that doc, not the one here. My mistake.1. I think the charts look identical, except the horizontal scaling of NASA chart is a little smaller, making the changes look more dramatic.
2. The NASA data indicates a change from the 1940 peak of a .25 anomaly (whatever that means, I suppose they must have picked a year to represent what think the "normal" temperature is) to a what looks like a 2012 peak of .75 anomaly, with a dip in temperature in between. Is this what I'm supposed to be so worried about?
3. I've browsed through the Ball presentation again, because the chart you've represented as his didn't look like his presentation. I couldn't find it in the video. Can you tell me at what time it appears?
This argument has not won me over.
Its still a Tim Ball misrepresentation of the data, or a dishonest claim, but its not from the video posted earlier.
I don't really have the time or want to dedicate the time to looking through his presentation, I've spent enough time watching that bullshit.
But look at it this way, there is nowhere else that he presents his arguments that I've found where you can really see what he is claiming.
If he was legit he'd have research papers, or properly researched articles, but all he's got is this lame video of a presentation to a roomful of deniers.
Contrast that with the work here.

Where every single statement is backed up with direct links to the research and data, where every statement is the result of thousands of scientists working together.
Why do you think that one kook is right and those thousands of scientists are all dishonest?
