If you are wondering which countries emit more carbon dioxide and should be more responsible to climate change, you may refer to the following heat map for more ideas.
This heat map is created by New Scientist that the size of each countries are based on the amount of greenhouse gases they emit.
There are 0.74 °C warming between 1906 and 2005, and the United States is responsible for 22 percent (0.15 °C ) while China and Russia are responsible for 9 percent and 8 percent respectively.
It is interesting that though the U.S.A., China and Russia are countries should be most responsible to the climate change, United Kingdom and Germany are countries mostly heated.
We all understand that global warming and climate change is a world-wide issue that we all should cooperate together, and tackle it. For more information, you can refer to:
