I attended a whole day long climate change symposium at my university where both sides presented their arguments for and against climate change. They picked the brightest and best minds of science to present both sides equally. It was hosted by Neil deGrasse Tyson and brought scientists from around the world, including NASA. It was the most interesting set of lectures I've ever attended and the result at the end of the day was very clear: No matter how you look at it, global temperatures are on the rise. Even the opposing side admits that temperatures are on the rise, but they argue it is good for the economy (land further north can produce more than before) or that it is normal climate fluctuations.
Up until about 2008, I too believe that the earths climate was just cycling as usual, but now there is too much data and evidence pointing otherwise. You don't have to look at temperatures only... it can be seen in nature. Birds migrate later in the fall and go back earlier in the spring. Flowers and trees around the world are blooming earlier than ever recorded. Pine beetles which can't survive extremely cold temps are surviving the milder winters to kill pines across the west. Glaciers are retreating at accelerated rates. To fully site and describe the statistical methods on these points would take YEARS, thus I won't be bothered to do that for you.
But more to that random fact I mentioned earlier:
If you want the details of how it is calculated, you can read the following quote from nasa:
So no, I'm not just taking statistics that I read and automatically believing they are true. I am considering the data measurements, analysis method and calculations done and the source to decide if it is reasonable or not. I'm sure there is a more complete statistical analysis report written on this data set, but I'm hoping this is detailed enough for you.
