Don't believe or deny. Just observe
There's an easy way to tell IF your climate is changing - though it provides no information about WHY.
Consider the meteorological record. Let's assume that it's been measuring things like temerpature and rainfall for 100 year.
In year #1 there was no previous highs or lows.
In year #2 the odds of an average being the highest (or lowest) on record was ½ there being only 2 values.
In year #3 the odds of that year being the highest or lowest for a given attribute are 1/3rd
and so on.
So in the 101'th year, what are the odds - assuming purely random changes in temperature, rainfall or whatever else you're measuring being the highest on record?
Now, consider Harmonic series. How many "record years" would you expect in (say) temperature readings if there was no underlying trend and each year's data was independent of all previous years? The answer is 1 + 1/2 + 1/3 + 1/4 ... + 1/N, which for a 100 year stretch would mean you'd expect 5 or 6 record years.
Now, check out how many "record years" there have been, where you live, in the past century. If the number is greater than 5 or 6, something's causing a temperature rise. if less, then there's cooling taking place. The underlying causes are not revealed, just the result.
