Its an intresting video, he is very slick he moves from quoting weather data to world average temps seamlessly he is very good at blurring the lines with data he moves from one to the other he talks about globle climate while showing graphs on local weather, it's a great magic act, where he infers the graphs are globle while they are actualy local cherry picked data, that show what he wants them to show, I am sorry I only got to 37mins and that was with some skipping.Data data data the man with it all!
The claim that data is tampered with is another scam he pulled back from when questioned, he avoided it by changing it to infured agendas instead of an out and out tamper. If you actualy read the reasons they have amended data they are very understandable. It's to avoid time of day records are recorded to infulannce data if one is recorded at 8am and another at mid day the data is not the same, data has to be averaged to be relavant, and is the globle average temp is not one country has experienced in one year but the average for the whole world for one year.
