I will take a leap of faith and assume this isn't intended as a joke. Yes, CO2 traps heat in air, trapped heat in air means hotter surface and hotter air, most of earth's surface is water, hotter surface means more water vapour, hotter air means more capacity to carry water vapour, water vapour forms clouds, clouds lead to precipitation. Climate change is leading simultaneously to two issues: not enough water, too much water. The former is obvious why: more water in air, means more rain, combined with more heat means more and bigger hurricanes/typhoons etc.. At the same time, due to more complex effects, droughts occur. Basically that is happening in regions where wind and ocean currents are not transferring moisture in to the region, but heat is causing evaporation. Other effects also contribute (eg. reduced snow pack in mountains, leading to there being less ice to melt to keep rivers flowing). You can google "what is climate change?"
