CO2 is plant food. Highly increasing CO2 emissions would reverse desertification, among other things. Trees would get bigger, etc. It would eventually make the planet warm enough for all (or most) of the *permanent ice, to melt (seasons are still a thing). Water levels wouldn't rise, that's pseudoscience. But a lot would become exposed.
*edit: akshually, if anything: water levels would drop, because water expands when frozen.
Long ago co2 levels were around 8-9000, now we are at about 4-600 ppm. 10 degrees C difference. I think we'll be fine. Melt the ice caps and drown the coastlines with all the properties of the assholes that live there. Winning.
