Re: False premise leads to false results
The sceptic tactic of at one moment saying they accept the world is warming but dispute the cause of it, and then next moment going back to disputing the world is warming and claiming it's all data manipulation is wearing thin.
Over a dozen measures of different properties of the earth by many independent scientific groups from different countries around the world show the Earth has continued warming since the 70s.

No objective person would look at this mass of data and conclude anything but the world is warming. Additionally with each passing year of continued warming the idea that this is just some natural cycle becomes less credible.
