Part of the summary:

For those who can’t follow what is being stated here is that data after 1960 will be “artificially adjusted” to “hide the decline”. In other words they were hardcoding in the program ways to manipulate the data to hide the decline in temperatures.

But then the scientific (???) journal, Nature finds nothing out of the ordinary in previous papers relying on the data.  At least we know Nature is on the global warming without scientific inquiry bandwagon.
