alt Hacker NewsNo, excessive fossil fuel use is the cause by an immense margin. It's completely dominated by commercial shipping (boats), followed by planes. Then I think it may actually be gas from cattle before cars. Bitcoin and AI are so recent and still relative to everything else small.

Electricity (including heating) is actually the single biggest source of greenhouse gas emissions, but transport is indeed number 2: https://ourworldindata.org/emissions-by-sector
Followed by agriculture & manufacturing.

Is that so? Too bad nuclear civilian ships are not common. https://en.wikipedia.org/wiki/Nuclear_marine_propulsion

This is completely incorrect. Aviation contributes 2.5% of global emissions (but is terrible on a per capita basis, as only around 10% of the world's population travels on any given year). Global shipping accounts for 2.3% of global human-made emissions [1].
In transport emissions, passenger vehicles dominate by far (with around 12% of global GHG emissions), even more so in developed countries. Then freight by road with 7.5% of total emissions.
Maritime shipping is actually the least carbon intensive way to transport goods over long distances by at least two orders of magnitude [2].
