If global warming is a big problem why dont we just reduce the temperature of earth using freezing technology?

we could all have one day where everyone in the world opens their fridge and freezer, and turns the air con all the way down, and everyone throws ice cubes into the ocean at the beach. if humans are causing global warming by driving cars and heating up our engines too much then we can just as easily cool it down with our technology. if anything if we all did this the earth would get way too cold, like zero degrees and we could all rev our engines twice as hard the next day to balance it out.

yeah just my advice given that everyone are so mad about it.
