[Superman] Does Superman have any weaknesses that exist in the real world?

If Superman were to show up in our reality, we wouldn't have access to his famous vulnerabilities.  Kryptonite and magic do not exist, at least in the way they do in DC comics.  Does the Man of Steel possess any weaknesses that we could could actually control?

It'd be tough. His third weakness, red solar radiation doesn't seem to be a thing in our reality, since photons coming from a red sun and a yellow sun aren't that different from each other. You wouldn't be able to just get red glass and shine a flashlight on him to drain his powers.
