If you hand pick your data set, you can probably show anything you want. I remember reading about the stock market, that if you just shift the starting and end points of "measurements" (for example about your fund's value), you could always claim an x% increase over the last y years.

So this here is an interesting data point - but it really is just that.

I wouldn't be surprised if there were places on earth where temperatures have been falling steadily, or have been rising or falling by extreme amounts.
