Ignoring all the junk science behind the temperature reconstructions, let’s have a look at the hockey stick grafted blade. Note how it starts at 1880, right after Australia’s hottest years on record.
Here is the current pre-1966 portion of the graph – a nice hockey stick caused no doubt by Grover Cleveland’s horse flatulence in the 1880’s
But it wasn’t always like that. NASA used to publish global surface temperatures back to 1866, which showed no net warming during the century from 1866 to 1966
Apparently Grover Cleveland’s horse wasn’t that bad after all. NASA simply hid the inconvenient pre-1880 data, because it wrecked the hockey stick.
But it is worse than it seems. NASA is not only hiding the pre-1880 warmth, but they are also tampering with the post-1880 data to increase the amount of post 1880 warming. The graph below shows how they have changed their own data over the past…
