I've come across a grammar task for English Exam preparation. There goes a text:
A survey by the Japan Agency for Science and Technology shows that Arctic ice is melting (Present Continuous is used to stress changes happening around now, as far as I understand) at a far quicker rate than anticipated.
... Now there is also less sea ice in the Arctic Ocean. It happens because ice ___________ (FLOAT) into the Atlantic Ocean.
Can I use Present Continuous in that gap to show that the state of floating ice is not typical for the region so I could imply the changes happening around now? Or is it better to use Present Simple to imply that the fact is true in general?
