@'Knigel': Have you heard of the documentary titled
"Chasing Ice"?
Here is a segment that has been uploaded to YT:

On May 28, 2008, Adam LeWinter and Director Jeff Orlowski filmed a historic breakup at the Ilulissat Glacier in Western Greenland. The calving event lasted for 75 minutes and the glacier retreated a full mile across a calving face three miles wide. The height of the ice is about 3,000 feet, 300-400 feet above water and the rest below water.
Seems the film in its entirety is (of course, due to CopyRight) not available on YT (at least, for viewers in the USA...do not know about other jurisdictions). It can also be seen on NetFlix, with a paid streaming subscription. And of course, on DVD for purchase.
Granted, this event was captured in May, 2008. Seasonally (Northern hemisphere) temperatures tend to rise, and of course glaciers will calve. There isn't really any other documentary footage of previous such seasonal events, of course. But, we've known for centuries that it happens....seasonally.
The entire documentary, however, does help to display something different. Cameras fixed in place for quite a number of years that recorded (still images, in sequence) the receding of glaciers, then the still images edited into a film based on them....this is called "Time-lapse" recording.
(EDIT): A very salient point is made starting at about 4:20 in the above clip............
(EDIT #2): Another clip RE: CO2 (from the documentary...it relates to anthropogenic additions of the gas):
