The global carbon dioxide levels increase the temperature when higher, and lower the temperature when lower.
Explanation:
The carbon dioxide is the most abundant and most important greenhouse gas. This gas has the property to trap and keep heat, thus instead of the heat going back into space, it is retained in the atmosphere. To put is simple, the more abundant the carbon dioxide is in the atmosphere, the higher the temperatures are, the lower the levels of the carbon dioxide, the lower the temperatures.
In recent times, the global carbon dioxide levels are experiencing an increase. While this is mostly due to the natural processes, the humans have been having bigger and bigger influence because of their activities. With the constant rise of carbon dioxide levels in the atmosphere, the temperatures have been gradually rising, and if the current trends continue it is expected that the global temperatures may rise by several C degrees.
The countries that contribute the most to the carbon dioxide emissions are:
