I do not like the phrase:
“that the human impact on climate change must be stopped.”
I agree we have some real issues with climate change as the result of human actions, and we need to start being more responsible than we have been for that.
And we also need to develop effective technologies for mitigating natural changes in climate.
Another ice age would not be a great thing for humanity.
We have the ability to start taking an active role in the management of climate within acceptable limits, and part of that will involve mitigating the effects of the amount of CO2 we are pumping into the atmosphere.
Part of the issue is that we have come to rely too strongly on the signals of the market for our decision making.
I agree with Hayek and Freidman and others that if we want any freedom left, then we need to decentralise our decisions making, and individuals need to claim as much autonomy as possible; and this needs to be done in a cooperative context that acknowledges the reality that we are all living together on this planet, we need to be responsible for the reasonably foreseeable effects of our actions on others and the environment.
So I am all for environmental awareness, and evolving individual responsibility – that will be an ever changing thing as new levels of understanding and awareness become available and spread.
And that is very likely to require us to have a very big impact on climate change, both human caused and natural.
The idea that the earth is in some sort of grand natural balance that somehow looks after us is pure myth. It seems very clear that the earth just does what it does, and all life adapts or dies. The earth has been both much hotter and much colder in the past than it is now, and at times it seems to have gotten very much hotter very quickly.
So by all means, raise awareness that everything we do has an impact on everything around us, and also be clear that we need to be developing some technologies that both allow us to clean up the messes we have made, and to mitigate against the sort of things that natural processes are likely to throw at us. We need to be able to make more impact on climate change, not less; the big thing is that we need to make that impact consciously and responsibly.
There are few simple answers, it is a very complex system, and we all need to be making our best efforts, and not relying on anyone else to fix it all for us.
