Introduction to Global Warming


The Global Warming is something that most people talk about these days. Global Warming is the increase in the average temperatures of the Earth surface. The main cause of this phenomenon is the change in the weather climate because of the humans who are working and making the factories where the dangerous gases come from and the dirty water too.

There are many problems for this phenomenon for example that the increasing of global temperature will cause sea level to rise, and it is expected to increase the intensity of extreme weather events and to change the amount and patterns of precipitation. Other effects of global warming include changes in agricultural yields, trade routes, glacier retreat, species extinctions and increases in the ranges of disease vectors.

Some global warming is good. But if extra greenhouse gases are made, the thermal blanket gets thicker and too much heat is kept in the earth's atmosphere. That's when global warming is bad.
