Would the melting of ice islands affect the weather across the seas?

I've studied a little about glacial melting and temperature changes in sea currents and worldwide. I couldn't find any definitive answer and since I'm no expert on this matter I'm a bit confused.

The setting

• The map is not to scale.
• The southern islands are volcanic islands near the poles, in a permanent frozen state.
• The continental land shown has normal seasons as in a temperate climate.
• The volcanoes are active, but they do not give off a huge amount of lava as they are already really high.
• There will be this enormous eruption on all islands that will change the temperature of the archipelago, thus melting a lot of the ice.
• The icy water will meet its end at the sea, even some small icebergs will meet the salty water.
• There are sea currents naturally going from the islands to the mainland.
• The ice islands are made 50% of land and 50% of ice, having the possibility of dispersing ice bergs and chunks of ice on the sea.
• Think of the size of the islands as in Japanese archipelago and the distance between them and the continent as the asia mainland distance to it.

Note that a lot of the setting is being forced a little bit to fit my needs, probably the sea currents and volcanic ice islands near the polar region are not too realistic. I want the outcome of this to be more grounded though, but some tweaks are allowed.

The question

Would the result of the setting throw the continent into a harsher winter never seen before? My ultimate goal is to freeze that lake, which is a salt lake and does not freeze over normal winters.
