Answer:
Greenland is a huge island that is covered with ice, due to warming this ice has begun to melt, reaching a point where more ice is lost per year than is gained.
The temperature levels on earth have increased abnormally since the industrial revolution, that is since CO2 emissions increased. The extra CO2 released into the atmosphere does not allow the heat generated from the earth to be released into space, so the earth has begun to heat up more than normal, causing temperatures to rise.
To avoid this, CO2 emissions should be reduced, this could be achieved by using clean energy to generate electricity, such as solar or wind energy. Also if industries improve their processes to reduce the CO2 they produce. Another way is to reduce livestock farming as this industry also releases high amounts of CO2.
As individuals, from our homes what we can do is to reduce energy consumption if it is generated with fossil fuels, for example turn off the lights if we are not in the rooms, unplug appliances that we are not using, do not use products that come from polluting industries, among others.
