I figured half of this out I think, but I am stuck.

x + 3 over x^2 + x -12 - x+4 over x^2 - 9
so the two denominators are x^2 + x - 12 and x^2 - 9.
Now I have to make both the same.
So far I did (x-3) (x+3)

The article cites an average global temperature of 55.13 F. This is 12.85 Celcius, or 286.0 Kelvin. (do a search on Celcius and Kelvin) The article claims that the global temperature has increased by 1.53 F or 0.85 Celcius.

Therefore, using the scientific scale, temperatures have increased from 285.15 K to 286 K. This is a 0.3 % increase.

What's the matter, isn't that shocking enough for you?
