The talks about environnemental pollution but actually means climate change.

He believes that climate is changing catastrophically because of humans burning fossil fuels.

Human do have impact on the environment, but impact on climate is a whole other story. Yet he keeps mixing these words together like their the same thing.

Climate change is a very superfluous concept which is actually political scare retoric that went from global cooling, to acid rain, to a hole in the ozone layer, to global warming and currently changing climate. Which is very strange because climate has been changing for ever. Nothing is stable but in constant flux. And the biggest influences on our climate are extraterrestrial factors like astroid impacts, Earth's orbit, and especially the sun.

Since humans started recording temperature some 150 years ago, earth has warmed about 1°C. And that is not corrected for heat islands because of urbanization. Its only about 40 years ago we started measuring temperature with satellite data.

Before the 19th century we rely on proxy data like ice core samples, archeological discoveries, isotopes in sediment or the amount of stomata on decayed leaves.

Melting gletsjers in Canada today reveal forests from 4000 years ago. Vikings had vineyard ls on Greenland a thousand years ago.

Anthropogenic global warming is a hoax to gain more control over people's lives and to extract their productivitie. Nothing more because there's no empirical scientific basis, just some arbitrary models that need constant adjustment.

So, this artist first claims to know about Bitcoin's PoW, then sees the light and keeps rambling about saving the 'environment' because of fossil fuel energy usage? He's a lost soul and should keep his statements to things he has really studied and understands. Otherwise he'll keep making a fool of himself.
