I feel that there are normal "earth" factors influencing climate but I think to ignore the pace change has recently grown and scientifically can be shown to agree with human action data is folly. Things like ozone, acid rain were real and their effect has been diminished because of steps taken to change chemical use such as Freon and its cousins, and increased use of scrubbers on plant emissions. Similar to the Year 2000 was a hoax, nothing happened - sure nothing happened because millions and millions of dollars were spent to make sure nothing happened.
Indeed the air was polluted by coal in the industrial age but years ago the number of factories and the population was far less than today. Phasing out major use of fossil use may have an impact on climate but it remains to be seen if it will be enough of an impact.
