Explanation:

Justification: Global warming is the rise in temperature of the atmosphere of the earth. This results, among other things, in the melting of polar glaciers, which leads to a rise in the sea level, causing floods in the coastal areas (for e.g. Maldives is a low lying nation and at a threat of being drowned by the sea level rise). Global warming has also led to massive glacial retreat in the past 50 years.
