All science is materialistic

[Anomalocaris]

i think your view that climate change will lead to extinction of human species is more crankish thant anything yet propounded by clark

If Humanity burns all the fossil fuels that are available to be burned, then, yes, that will be the likely outcome.

no it won’t    first of all, long before we come anywhere close to burning all the fossils fuel there is to burn, the impact of having burned what had already been burned up to that point will diminish our ability to burn any more, kill large number, maybe even majority of us, but not come within a million light year of actually making us go extinct.

the consequence of uncontrolled support or further anthropogenic greenhouse effect is ever greater misery and loss of ability to generate economic value on the one hand, and diminution of economic capacity to support further extraction and burning of fossil fuel on the other.

Doing things that that consumes great economic out out and in the process harm humanity in a societal scale creates its own checks and balances.    eventually there would not be enough economic output to support the same level of destructive activity.
