Anthony Watts is back to the dregs of deniers again with another "essay" by uber-conspiracy theorist Tim Ball (archived here). Tim just recycles his hogwash from previous "essays" as a typical Gish gallop, so there's no need for me to go through this one bit by bit, if I could be bothered. I'll pick up on this sentence though. He wrote:
The 2001 Intergovernmental Panel on Climate Change (IPCC) Report included evidence in the form of a “hockey stick” graph, showing that the Medieval Warm Period (MWP) did not exist. Less prominent, but just as wrong, was erasure of the Little Ice Age (LIA).
Tim for some reason has a fixation on the medieval warm anomaly and the Little Ice Age. He probably thinks that if climates changed anywhere in the past without being caused by greenhouse gases, then the current warming can't be caused by greenhouse gases. That's a logical fallacy of course. Just because bushfires get started from lightning strikes doesn't mean that they can't be caused by humans.
Here is the relevant section of the 2001 IPCC report. Both the medieval warm anomaly and the Little Ice Age were real. What Tim is objecting to is that science now shows that neither of them were global in effect. Not everywhere got warm and cold during those periods and those that did didn't get warm and cold all at the same time.
More studies have been done since 2001, not surprisingly. The latest IPCC report has this to say (TS.2.2.1 Surface):
Continental-scale surface temperature reconstructions show, with high confidence, multidecadal intervals during the Medieval Climate Anomaly (950 to 1250) that were in some regions as warm as in the mid-20th century and in others as warm as in the late 20th century. With high confidence, these intervals were not as synchronous across seasons and regions as the warming since the mid-20th century. Based on the comparison between reconstructions and simulations, there is high confidence that not only external orbital, solar and volcanic forcing, but also internal variability, contributed substantially to the spatial pattern and timing of surface-temperature changes between the Medieval Climate Anomaly and the Little Ice Age.
Tim would like science to have stopped short in the 1960s, going by the ancient drawings in his article. He also thinks that temperatures on an ice sheet on the top of a summit in Greenland make a good proxy for global surface temperatures. He's a real nutter. Nuttier even than Denier Don Easterbrook, who we haven't heard a peep from in ages.
Oh, and in case you think Tim wrote a coherent article, he didn't. As well as the medieval warm anomaly and the Little Ice Age, Tim jumped from one topic to another with no rhyme or reason. I've listed below most of the topics he covered and provided links so that you can compare facts with Tim's paranoid ramblings, if you can stomach them:
- Stolen emails from the Climatic Research Unit
- William Connolley
- Andrew Weaver
- Antarctic ice core records
- Holocene climatic optimum
- GISP2 in Greenland
- Rising sea levels
- Hubert Lamb
- The IPCC
If you want to find out more about Tim Ball's "science" and his paranoid conspiracy ideations, you can do so here and here and here and here and here and here and here and here and here and here.
Goodness me. Have I really wasted that much cyberspace on that despicable little man? Perhaps in future I'll just link back to here as a ready reckoner.
From the WUWT comments
Tim Ball is an unsavoury character and he tends to bring out the same characterics in others. The more reasonable deniers (if there is such a beast) generally avoid commenting on his articles. It's mainly the weird and wacky who do so. Like knr who says:

IPCC is a parasitic organisation whose existence relies on AGW , with Mann and his gang are merely parasite facilitators who have done very well out of their ‘work’ , without its ‘host ‘ like any parasite its it would be dead through starvation.
With that in mind, is anyone surprised to find its acts in the way it does?
The saddest part is the very people that should have acted has gate keepers to such behaviour have either played the three wise monkeys or deep their own snouts in bucket of funding slops no matter how much ‘filth’ they had to clog their eyes , ears and mouths with . And for that we may all pay the price as the people start to view all science through the dishonest, hypocritical , poor scientific approaches used by climate ‘science’ .

Maybe one day there’ll be a presidential inquiry into who said what and when, but there again presidents don’t like asking embarrassing questions about previous incumbents, as they don’t want to set a dangerous precedent.
