So saying that more CO2 even double current CO2 is bad for life is just a lie.

We were at 280 ppmv before the Industrial Revolution kicked off.
Currently, climate sensitivity, at a 'doubling' of carbon dioxide ( 560 ppmv ) will lead to the 3-C world ( 5.4 F warmer ).
Presently we're at around 412-ppmv.
Any use of the word 'life', in the context of justifying no climate action, would require some context.
Conditions supporting only single-cellular life on Earth may be a turn-off for some. Although it would be 'life.'
