Lots more declines unhidden: Maybe this is why they didn't want us to see the data

The Reference Frame: HadCRUT3: 30% of stations recorded a cooling trend in their whole history
In this sense, the warming recorded by the HadCRUT3 data is not global. Despite the fact that the average station records 77 years of the temperature history, 30% of the stations still manage to end up with a cooling trend. The warming at a given place is 0.75 plus minus 2.35 °C per century.
...
Imagine, just for the sake of the argument, that any change of the temperature (calculated as a trend from linear regression) is bad for every place on the globe. It's not true but just imagine it. So it's a good idea to reduce the temperature change between now and e.g. the year 2087.

Now, all places on the planet will pay billions for special projects to help to cool the globe. However, 30% of the places will find out in 2087 that they will have actually made the problem worse because they will get a cooling and they will have helped to make the cooling even worse! ;-)

Because of this subtlety, it would be an obvious nonsense to try to cool the globe down even if the global warming mattered because it's extremely far from certain that cooling is what you would need to regulate the temperature at a given place. The regional "noise" is far larger than the trend of the global average so every single place on the Earth can neglect the changes of the global mean temperature if they want to know the future change of their local temperature.

The temperature changes either fail to be global or they fail to be warming. There is no global warming - this term is just another name for a pile of feces.
