Answers to the 15 questions (No.23) Posted by Junya
In trying to answer the question “What is the country with the highest carbon dioxide emissions?”, I selected two sources, one was the website of “The 5 Countries That Produce the Most Carbon Dioxide (CO2), and the other was the website of “Each Country’s Share of CO2 Emissions.”. From the first source, I learned that China is the country that emits carbon dioxide the most. The very cause of CO2 emissions is coal burning which accounts for about 66% of the total energy in China. However, China tries to plan to decrease the use of coal and pollution in the air by using renewable energy sources. Because the world rank of emitting CO2 is written in order and explain the details of each country, I can trust the information provided.
From the second source, I got to know each country’s share of CO2 emissions as of 2015. China has the largest CO2 emissions, 28% of total share, followed by the U.S., India, Russia, Japan, Germany, South Korea, Iran, Canada and Saudi Arabia. The larger the population is, the higher the rank becomes. Because this data is a result of a precise investigation and the table is easy to look at, I can trust the information provided.
In conclusion, toward the question “What is the country with the highest carbon dioxide emissions?”, we can say that CO2 emissions accounts for 70% in the top 10 countries alone.
Countries which ranked to the top 10 should be aware of CO2 emissions and try to decrease them in the future.

Answers to the 15 questions (No.13-No.15) Posted by Aoi Q13. Can creatures adapt to the effect of global warming? A13. As you know, global warming affects not only humans but also animals. So, many species on earth are now exposed to the severe environment. I’ll tell you how animals survive and adapt to the new environment. There are mainly two ways for animals to keep on living. The first way is to move to a new land. It’s becoming hotter and hotter now, so some animals like pikas started to look for a new habitat. They are moving to a northern area to find a comfortable place for them. This way is not an adaption, but I think that it’s also a reasonable way because they don’t need to change their lifestyle rapidly. And, the second way is to adapt themselves to a new environment. This is a main content of this question. Take insects and birds, for example. The temperature of the world is getting higher and higher, so the period of four seasons are affected more or less. Thus, i...

Perspective from national people in the U.S.  posted by Junya Many national people in the U.S. believe in global warming according to an interview in a street. There are some reasons why they think global warming is really progressing. For example, there is scientifically valid proof that global warming exists and it’s getting hotter and colder in Georgia like there never really snowed the way people have seen in the past two years as of 2014, so climate change is really occurring. In addition to such opinions, there is an opinion that climate change and global warming are created by the activities of human. In any case, many national people in the U.S. think global warming is really advancing. Reference O. (2014, May 29). "Do you Believe in Global Warming?" Street Interviews.
