It seems you partly agree with my point, which is this: climate change consists of a long-term upward temperature trend, with normal weather variation superimposed on top of it. Thus, you would expect a few up years, a few flat or down years, a few more up years, etc. But over several decades, the trend would be upward. And that is exactly what we're seeing, as shown in the link above. i.e., if 2000-2014 contains 13 of the hottest years of the last 130, then it is clearly part of an upward trend on a 2+ decade time scale, even if temperatures jumped up and down a bit within this 15-year period. Further, since climate change is a multi-decade or multi-century process, we can't ignore it just because the world hasn't ended in the first 30 years. The climate has clearly changed, but the biggest changes are yet to come.
I think you misunderstand some statistical techniques when you criticize instrumental precision. Yes, there are measurement errors at individual sites, and there is no way to measure the whole globe's temperature directly. However, two factors make it possible to estimate the long-term global trend very accurately. The first factor is the use of a longitudinal study format, where temperature is measured repeatedly at the same location. This makes it possible to observe the trend at that site very accurately -- i.e., the long term trend will emerge despite small measurement errors on individual days. Second, even if you can't measure the whole planet's temperature at each time step, you can observe that the weighted mean of your sampling sites is rising. If you choose the sites carefully, and observe them repeatedly, you can estimate the global temperature trend with a high degree of certainty; i.e., you can say that even with random errors in individual measurements, there is a greater than 95% (or 99%) chance that the actual temperature increase is within a certain (narrow) range around the number you've calculated.
It sounds nice to us (as a warm-blooded species who mostly live in colder climates than we evolved in) that temperatures are rising more at night and in winter (exactly what you'd expect if you threw a thicker "blanket" of CO2 on the planet), but that doesn't make climate change any less dangerous. It is still a sudden change in the temperature and weather regimes that human and natural systems have adapted to over thousands of years, and a small change can make a big difference. The difference between the last ice age and today is only about 5 degrees C, and we're on track for a 2-3 degree rise from pre-industrial times. I wouldn't shrug it off lightly.
