I remain highly skeptical that CO2 is as big of a problem as climate alarmists say it is. There is just too many other factors that would have a much larger impact on the climate like the Sun, Earth's orbit, Earth's axis tilt, where clouds form, ocean currents and so much more. If the question was what to do about pollution, for example plastic waste, industrial chemicals and so on, then that would be a discussion we should be having.
I think we should be always looking at better means of public transportation, better ways to provide electricity and sustainable farming, but the focus on CO2 is suspect.
