They are a problem. But they also break down pretty quickly, just like methane. Unlike CO2, which can stay in the atmosphere for hundreds of years. That means they are much less of an issue than that number suggests unless we start mass dumping all of that into the air as opposed to recycling it. That is btw. happening with methane, which is leaking into the air from e.g. melting permafrost in Siberia, intensive farming and soil tilling, etc. Also, some heat pumps use alternate fluids. So, we might clean that up further. But compared to the massive scale with which we are producing CO2 currently, that's a minor issue.
