Today, Sri Lanka experienced a historic cold weather. The vast majority of people in Colombo and many other places (perhaps except the very old) have not experienced such cold weather in their living memory.
Weather patterns around the world are undergoing drastic changes. At the age when the global warming is becoming a problem, its strange that the lack of global warming is blamed for the cold. The cloud cover stops the radiation from the sun reaching the surface of the Earth and therefore, the Earth has got cold. It is given as one reason for the cold.
Global warming is not bad. Life on Earth would not have been possible if there was no global warming. What makes it dangerous is the excessive global warming.
