Honestly, the existence of everything is directly/indirectly related, bitcoin has an impact on the climate. I could mention the situation that Bitcoin mining can also pollute the environment due to noise, heat, and ewaste. Bitcoin mining operations are often located in areas with cheap electricity, often with lax environmental regulations. But to be fair, it's not as harmful as other behavior that we think of as having a different climate impact, and the climate issue is common to everything, not just related to bitcoin.
