//...right but we were talking about which would be economically worse.... climate change or doing nothing about climate change...//
But that is not the choice because it's quite evident that little or nothing can be done to prevent climate change. It's been tried and global temperatures are still on the up. That's not ideological, it's fact:
https://www.climate.gov/news-features/understanding-climate/climate-change-global-temperature
"Earth’s temperature has risen by an average of 0.14° Fahrenheit (0.08° Celsius) per decade since 1880, or about 2° F in total.
The rate of warming since 1981 is more than twice as fast: 0.32° F (0.18° C) per decade."
The last sentence is telling: that's the period when the greatest efforts have been made to tackle the climate; and that's the period when the greatest increase has occurred. Couple this with the fact that most of the largest polluters have no intention of making any substantial changes anyway and it is obvious that the idea of controlling the climate is pure fantasy.
People need to be told the truth and not peddled with nonsense. More importantly governments need to react to the truth and not rely on some Utopian ideal that has absolutely no chance of bearing fruit. Adapting to climate change will be every bit as difficult as trying to combat it - more so for people who live in places where life may become unsustainable in the long term. But the difference is that it stands a far greater chance of producing a successful outcome.
