That's actually exactly my point. I once went through and estimated how much the atmospheric temperature would increase by burning kerosene for jet fuel. It wasn't accurate and I didn't take a lot of variables into account, but it was a very noticeable increase. The point is, dumping mass amounts of heat into the surroundings can have a noticeable effect on ambient conditions, hens my question, "how much of this is caused by data centers?"

humanspiral@lemmy.ca is correct, this is a minuscule effect in comparison to solar warming. At the end of the day, the problem with global warming is pretty simple. A body in space can only remove thermal energy by radiating it out (black body radiation). This is a fixed value and quite easy to calculate for a sphere. However, parts of the atmosphere absorbs and re-radiates some of that black body radiation back to earth, this is what keeps it at a livable temperature and not significantly below the freezing point of water. Co2 and methane are two gases that absorb and re-radiate that energy back to the ground, hens the concern surrounding them. But the system is more or less fixed, and adding thermal energy will result in a change to the system's overall energy state.

If you approach the problem from this stand point, your goals shift slightly from "reduce emissions" to "reduce energy usage." However, that's not profitable.
