The graph is self explanatory

It's self explanatory in that it's a short cherry-picked trend using the least representative of all global temperature datasets.

The data is snipped off this data:

If you take raw data like this and choose your intervals carefully, it's very easy to find short term downward trends in an overall rising trend.

Hi muso

Yes you are correct.

I have been using the snippet to show that there has been no warming since 1998.

In other words if you smooth out the snippet temperatures are falling not rising.

There are four problems.

1. The Hadcrut dataset doesn't adequately cover the near polar regions. The GISS dataset is much more comprehensive, and this shows a more pronounced warming trend.

2. It's a land surface dataset only. To be comprehensive you need to consider the increased heat uptake in the ocean as well as the land surface.

3. If you say that there has been no warming, what's your line of best fit for that data? You do realise that you can't just take the first and last points?

4. There are other factors at play apart from carbon dioxide, especially taken over such a short period. Everybody, including every climatologist in the world realises that there is short term variation. Even if the trend leveled off over a short period, it doesn't disprove the fact that radiative forcing for carbon dioxide is a logarithmic function of concentration.

You're simplifying the hypothesis to such an extend that it becomes a strawman.

Is there a single climatologist in the world who states that there should be a steady increase with absolutely no natural variation over a 10-15 year period as a result of rising CO2 concentration?

If there is, then please let me know.

Now, are you stating that there is an issue with the radiative forcing equation for carbon dioxide? - with climate sensitivity?

What exactly are you stating and how does it differ from what climatologists the world over are claiming?

Whatever dude.......??!!

You use it when it suits you and discard it when it doesn't....

Science doesn't work like that now does it??????

Anyway according to that political body known as the IPCC who publish scientific papers based on computer simulated models of our climate.

All the heat should be at the equator should it not?????

With the hot spot and all.............???????????

So then what's wrong with these readings......??????????
