That's an average, you genius. If the average worldwide temperature at the surface was 30C, that would mean it would vary from that baseline, instead of varying from our present world average which is around 16C. A really crude way of looking at it would be to take the hottest day you experienced this summer and the add 14C to that number.

You cannot discount cattle as a non human source...

Natural sources of methane 36% and human sources are 64%.
