Pretty much. You have to remember there have been multiple ice ages already and people weren't involved at all. As the ice melts on the poles it adds fresh water that raises the freezing temp closer to 32F - 0C which it will do in winter months. You also have to step back and look at the earth in it's environment as a whole in the galaxy. There are way bigger forces at play than just people and the earth runs through cycles as well as our sun/galaxy, they are just way longer that the human mind can redily comprehend so many people just blame something in the moment like global warming which leads to global cooling and an ice age.
