The sun is at its lowest level of activity in 80 years.
So why is the ice still melting?
Actually ...

Time to finally explain this to you ... just because I am finally bored enough to stop laughing whenever you post it.
When the energy from Sol fluctuates the temperature goes down naturally, due to the increased atmospheric activity it causes on Terra. However when Sol is steady and calm, there is much less atmospheric shift, therefore lower wind levels and less heat transfer, so the temperature actually goes up on the surface of Terra. But oh wait ... that's just too scientific for you, how about this answer, more to your level of thinking:
That's just the way it is.
