No, I'm not saying that and I don't think 1.5% is particularly large. Moreover many of these projects are built out with on site 0 carbon generation so they're in some ways a net benefit.
In fact, I'm unaware of any new AI data center also being built with 0 carbon generation. Do you have a source?
Ohhh, carbon neutral energy generation, if only we could use that to replace the non-neutral energy sources, instead of using it to power virtual X-Ray goggles so MAGA incels can goon at "naked Taylor Swift". Or to answer "please do my work for me" of lazy fucks planet-wide. You know, to stay relevant to the comment thread of "Oceans hit highest temperature on record"...
The problem is not that we are building more things that use electricity, the problem is that we are generating electricity using fossil fuels. We should have phased out fossil fuels decades ago yet here we are ramping it up while everyone's bickering about inconsequential bullshit like datacenters.
Datacenters are not the problem. Construction is not the problem (except concrete which generates huge emissions but we can't really do much about that). Some things are infinitely easier to fix than others. Power generation is such a thing. We have the solution, we've had it for like a century (nuclear) and we're getting even more solutions.
We could run all power production with hardly any fossil fuels if we really wanted, nearly all land transport could be electric. These two changes alone would eliminate the vast majority of emissions. And we can do that, it's realistically possible.
We could also probably run global shipping and aviation on non-fossil fuels if we really wanted to, though I don't really know anything about that. There are large scale mining excavators, dozers and trucks running on electricity, and hybrid solutions.
Stop bickering about the small stuff. The only thing we should be focused on is transitioning all electricity production to green as fast as possible. That takes care of almost half of all emissions by itself and opens up lots of opportunities for solving other problems without emissions. For example we could use green energy to produce hydrogen from water, or biogas, ethanol etc, and then we'd have emission-free fuels we could use where combustion engines are still necessary.
But no let's just bicker about data centers and other inconsequential shit while the world ends.
