Did you know, in the recorded history, the average temperature of the earth’s climate system has been rising at the fastest pace over the past 50 years? Owing to this rise in temperature, the average sea level has risen around seven inches in the course of the past century.
Here you will learn about what is global warming in Urdu and English.
How will you define global warming? Here is a comprehensive definition. Alternatively known as climate change, global warming can be defined as the observed century-scale increase in the average temperature of the global climate system and the effects caused by such a rise.
Global warming occurs due to the accumulation of air pollutants and greenhouse gases, like carbon dioxide, methane, chlorofluorocarbons, ozone, nitrous oxide and water vapors, in the earth’s atmosphere. Such elements absorb the solar radiations that have bounced off the surface of earth and prevent them from escaping into the space. In other words, the greenhouse gases and pollutants remain in the atmosphere for years to centuries and trap the heat radiations which causes the planet earth to get warmer and harsher.

The scientists observe a close link between global warming and extreme weather conditions. According to them, the rising global temperatures lead to hotter and longer heat waves, more frequent droughts, more powerful hurricanes and heavier rainfall.
As the temperature of oceans on earth is rising, the tropical storms are able to pick up more energy. It indicates that global warming has the potential to turn a category 3 storm into a more powerful and devastating category 4 storm.
Other effects of global warming are: early snowmelt, dramatic water shortages, increased flooding, outbreak of infectious diseases and extinction of many animal and plant species due to disruption in their habitats. Here you can also learn about what is global warming in Urdu.
