tl;dr

Brevity is the soul of wit. This is a discussion forum, not a virtual lecture hall. What's your point?

I find it interesting that your chart showing a mean of the major temperature records shows no increase for the period in question yet each of the temperature records shows an increase.

It's because it's a dishonest or wrong representation of the data. There was warming during the last 17 years, as you show

All proper scientists use the Daily Mail rather than peer reviewed articles.

If you click on the link the article gives, you get will get to the author of the graph you show that has been linked from the Daily Mail:

[UPDATE (17/03/13): David Rose has written an article in the Mail on Sunday which, by eye, seems to use the top left panel from the figure below, but without mention of its original source. In the article David Rose suggests that this figure proves that the forecasts are wrong. This is incorrect - the last decade is interesting and I have discussed these issues previously (as have many others) and I have even co-authored a published article about the most sensitive simulations being less likely. David also incorrectly suggests that the shaded ranges shown are 75% and 95% certainty. As labelled below, they are actually the 25-75% and 5-95% ranges, so 50% and 90% certainty respectively.]

[UPDATE (21/03/13): Mail on Sunday acknowledge that Climate Lab Book figure was used & redrawn and apologise for lack of credit in article update.]

Normally people don't understand the timescale that is being dealt with in Global warming. It's just human nature that we view things in terms of what is happening right now. If it's a heavy hurricane year, it must be global warming! If it's a cold year, global warming is fake! Everything is on a much bigger scale than that.

In that last image, the temperature is has still risen over a period of time no?

Good stuff, Aractus. I look forward to your next posts on this subject.

I don't really know if all this panic about climate change is right or wrong, but I do know that the climate as always been changing for thousands or millions of years.
