I'd like those who continually deny man-made climate change to name one national government in the world - just one - that agrees with them. 

What does that mean? Nothing at all? If there were justifiable doubt wouldn't some major countries say so? Is the 'climate change conspiracy' really that complete? 

The science may indeed change over time - that is the nature of the scientific method - but the fact is that it's the best science we have, it's been consistent for several decades now, and the threat is so significant we'd be fools to ignore it.
