Unfortunately, your opinion and experience on the weather is worth nothing as regards climate. Neither is mine or anyone else's. We only "experience" a sliver of a silver of weather in a sliver of time. Weather is variable everywhere and so is climate, and we have two different words for a good reason. They are different things. The Earth's climate is always cycling from whatever it was to whatever it's going to be. It is never static. There have been several major ice ages, most likely the result of changes in the sun. There are long cycles and short cycles and short cycles within long cycles. Volcanoes are responsible for 95% of air pollution, so when we screw-up the air someplace, it's only a small, local portion of the Earth's surface. Many of our cities with poor air quality have it due to poor circulation in that place due to geography. L.A. and Beijing are two good examples. Others do have poor air quality due to the quantity of people living there. Ten or fifthteen million people living in one city ARE going to generate a lot of waste: air, water, solids, et al. They all qualify as a micro climate, and we should clean-up our act. But we don't affect climate. The sun and geography and the Earth's rotation are responsible for climate. Climate can also be altered by close encounters with asteroids and volcanoes. Tambora gave us the year without a summer in 1815.Anyone who has an interest in Agriculture or Horticulture, who is fourty plus years old must notice the climate changing. My experience is as follows; when I was an apprentice Gardener back in the mid 70s, we used to mow the grass for nine months of the year from March through to end of November, after November it was impossible to mow quite simply because it was too wet, frosty or covered in snow, anyway the grass just wasn't growing. Nowadays its not uncommon to see folks cutting grass at any time of the year, it doesn't stop growing, so the winters are becoming warmer and summers hotter, storms are becoming more frequent and more ferocious. I believe its no coincidence that skin cancer is on the increase as the ozone layer breaks down. I may be wrong but I can only go by my experiences for what there worth.
As to what's normal, good, or whatever positive characterization you want to use: an ocean-run salmon pickled in alcohol long before the commercial use of mercury tested way over the limit when tested in the 1970's(?). Arsenic is a common contaminant in well water in areas with certain kinds of underground rock. That's normal, ~and completely "natural".
The amount of CO2 has varied widely over the eons, and we are at the lower end of the scale now for reasons unknown. All we really know is that the Earth got along just fine when CO2 was at the other end of the scale. It's not a pollutant, in my opinion. But you know what that's worth...
