What is global warming? This is a very popular issue all over the world. In order to learn more about global warming, we should go through what makes the earth warm and how warming affects the earth. The first thing we need to be familiar with is the greenhouse effect. It plays an important part in controlling the earth temperature. Thus, we need to know how the greenhouse effect is to know how it could affect the earth.
Global warming and greenhouse effect:

And this is the question. How can the ocean current affect the climate? It should be global warming, right? In fact, it is global warming. But global warming is the background of the climate change. So I could tell that the ocean currents have their own direction to flow. Although the surface of the sea we see is clam, there are lots of differences under the seas. The flow of the water depends on its mass. Its density, temperature, and concentration will influence the ocean currents. The ocean currents play an important part to modulate the heat energy on the surface. For example, the lower latitude ocean currents will bring the warmer water to the higher latitude areas. That means the ocean current control the heat balance and they may affect the climate. So the greenhouse effect is one part of global warming and it makes the South Pole ice melt. And we know that ocean current may change the climate. Now we have to connect two things and make it relate to the movie. A large volume of fresh water goes into the sea and dilutes the salt water concentration of the sea because of the melting of the icebergs. So the melting water affects the ocean current and destroys the balance of the heat on the surface. Because the heat balance doesn’t exist anymore, the climate changes rapidly and causes an ice age. This is what the movie
