Global warming means an increase in the average temperature of the Earth's near-surface air and oceans that is causing a continuous threat on global environment”. Global warming is like a heater that is continuously warming up our environment. If we don’t switch it off it will definitely burn us all.

Causes of Global Warming

Global Warming is caused by the Greenhouse effect. There are four steps in the Greenhouse effect. The heat generated by the sun is absorbed by the atmosphere and are trapped by greenhouse gases. The gas then absorbs the light and is remitted back to the Earth’s surface and warms it even more. Some of the naturally occurring greenhouse gases are Methane and carbon dioxide. This is the way the Earth keeps itself warm enough for humans to live on it. But the cause of concern is the human activities that are causing an alarm are emitting of excess carbon dioxide and CFC. The continuous increase in pollution is another major cause of rapid increase in our mother earth’s temperature.

Effects of Global Warming

Earth is showing us signals of hazard which we must recognize. The temperature over the past century has risen one degree Fahrenheit over the last century. These last few decades have been the warmest this century. The sea level has risen 4 to 10 inches, and mountain glaciers world-wide have begun to retreat. We can also notice the change in temperature and decrease in rainfall in recent years
The effects will have a huge impact on our lives in the coming years One event is major drought all around the world. With the warming of the planet, the water on the ground would quickly evaporate causing the rivers and lakes to quickly dry up. This would lead to crops dying from lack of rain, which would lead to food prices to skyrocket, which would lead to people dying from hunger .Another event that would occur from global warming is the drastic rise in sea level. As the Earth warms up, the polar ice caps will start to melt. All cities along the coast would be flooded from the rise in sea level. This would cause people to move inland, and with more people inland, it would cause a shortage of space in some areas. Global Warming would also cause extreme weather. Thunderstorms would be more powerful than they have ever been. Tornadoes would be stronger than they normally would. With the warming of the surface it would also warm the ocean over time. This would cause hurricanes to be numerous and stronger than they have ever been.



Conclusion

It is time we must understand that human activities and climate is interdependent and inter related. If we don’t stop emitting harmful like carbon dioxide and CFC one day soon we will burn in the same fire we lit, as it is said “You will reap as you bow” So we must understand “The Earth provides enough to satisfy every man's need but not every man's greed.”
