Global warming begins to show its presence more and more lately. A huge block of floating ice is beginning to break apart from Greenland’s coastline as it begins to drift in the Arctic Ocean. Scientists believe that it is just another effect of the global warming induced by the greenhouse gases present in our atmosphere.
Biggest one yet
Polar scientist Ted Scambos, from the National Snow and Ice Data Center, believes that this block of ice is the biggest one to leave Greenland, making for the largest opening north of Greenland. This sea ice represents one of the thickest and oldest present in the Arctic. The powerful winds and currents carry a lot of ice up against the northern coastline of Greenland. This is where it accumulates and clings for years.
Crowds and stadiums
This process is very similar to what happens to the crowds of people on stadiums during popular sporting events. The ice in front is pushed by the one coming from the back until it gets packed extremely tight and this happens for years, making it thick and durable. Another example would be the mounds of ice and snow which accumulate by the side of the road. You noticed how long they last?
Global warming, however, began to loosen this tightly packed ice as the Arctic begins to warm up faster than any part of the planet. Just this last February the temperatures recorded were higher than the usual.
The ice in the Arctic used to be frozen all around the year but now it begins to rattle and in northern Greenland, it became thin and loose. Now, a strong gust of wind is sufficient to push it away from the coastline and let it drift into the Arctic Ocean.
