Walter from the latest graph 1935-36 is certainly not anywhere near a record for cold temps.
Looking at the graph there isn't much difference between the early 1930s and the current time.
In my opinion the global data should also be carefully examined to see if it was created using the same techniques that created the erroneous US Data.
This isn't the first time that we were presented with erroneous graphs which purport to demonstrate the anthropogenic warming argument. The famous Hockey Stick is another example. Whether these are errors or deliberate falsifications we don't know. But the proposals made by Gore and others will be very costly and will probably affect the way we live (although perhaps not the way Gore lives). So they better be damn sure they know what they're talking about.
