The Artic Ice Cap is NOT increasing in size. In fact, the summer extent is consistently reducing over time. Check articles on the new norther shipping routes that are increasingly being tested by Chinese and Russian companies as expectations of sea ice extent reductions are becoming mainstream.

While I do not know, if the polar ice cap is increasing or decreasing, but would not be an indication or denial of global cooling or warning.

I think that e.g. the cooling effect due to reduced sun activity (if it exists) moderates anthropogenic warming impacts, the same other natural impacts on the climate would such as volcanic eruptions etc.

We should realise that something as complex as climate has many contributing factors that lead to change. To assume that everything is caused by humans or everything by natural causes is far too simplistic. For that reason it is rather difficult to make any precise predictions of the future. There are surely factors that support cooling effects and others that at the same time support warning effects. The balance, however it is, is what counts; as such it is no the question whether it is the one or the other.
