Answers to the 15 questions (No.26) Posted by Junya When we try to answer the question “What is technology to prevent global warming?”, I selected two sources, one was the website of “5 tech innovations that could save us from climate change”, and the other was the website of “Future technology ‘cannot rescue’ mankind from climate change, say expert.”. From the first source, as I learned in question 25, innovation technology may save the earth from global warming. Power generation, transport, food, manufacturing, and building are very important when we prevent global warming from advancing. These are the main factor of emitting CO2, so we need to improve them right away. Because in this article solutions of global warming are explicitly mentioned, I can trust the information provided. From the second source, I got to know that future technology would not save the earth from global warming, experts have said. No matter how hard we try to reduce CO2 in the atmosphere, it is continua

Answers to the 15 questions (No.25) Posted by Junya In trying to answer the question “What are international approaches to prevent global warming?”, I selected two sources, one was the blog website of “The Ultimate Approach for Global Warming”, and the other was the news website of “Global Warming Solution”. From the first source, I learned that if the current situation continues, global warming will be progressing. The normal global rise in which the ambient temperature usually rises several degrees will have a significant impact on the global climate. One solution is that fostering more use of organic foods is an efficient way to prevent global warming. Because this article provides us with information with four pictures, it was easy to understand the content of this article. From the second source, I learned that global warming is due to human influence, but human may save it by innovation technology. Other solution is an approach called "stabilization wedges". This m

Answers to the 15 questions (No.24) Posted by Junya In trying to answer the question “Since when has global warming become a problem?”, I selected two sources, one was the website of “Global Warming Timeline”, and the other was the website of “A brief history of climate change”. From the first source, I got to know that when First Industrial Revolution began, in the late 19 th century, CO2 emissions started to increase earnestly because of coal, railroads and land cleaning. When Second Industrial Revolution started, other factors, such as fertilizer and other chemicals, electricity and public health accelerate growth. Because this chronology was written based on the fact of the past, I can trust the information provided. In the second source, I learned that British ironmonger invented the first steam engine, and that time is a pioneer of the Industrial Revolution, so we can also say that at this time, global warming began to appear. As BBC, which is famous British public broadcas

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, Sout

Answers to the 15 questions (No.22) Posted by Junya When we try to answer the question “What is the effect on Japan?”, I selected two sources, one was the news website of “Global warming could make typhoons 20 percent larger.” and the other was the news website of “Global warming hits Japan’s cherry blossom season.”. From the first source, I got to know that global warming will be responsible for the organization of powerful typhoons which are 20 percent bigger that present ones by the end of 21st century. Since typhoons come to Japan from summer to autumn every year, typhoons will have a tremendous impact on Japan. Although what is written in this article is based on the prediction from recent status, the Japan Meteorological Agency is also alerting similar things. Therefore, I can trust the information provided. From the second source, Japan’s cherry blossom season gets faster because of rising temperatures. Regarding this year, cherry blossoms bloomed about 9 days earlier tha

Answers to the 15 questions (No.21) Posted by Junya When we try to answer the question “What is the effect on our food?”, I selected two sources, one was the website of “Global Warming Effects on Food.” and the other was the website of “Climate impacts on Agriculture and Food Supply.”. From the first source, I l earned that there are threads of global warming to food production. For example, yields are reduced, irrigation is increased and fisheries are reduced. In any cases, it works negatively on agriculture. Because effects on our food are written in order and based on recent state of things, I can trust the information provided. From the second source, I learned that global warming can affect food security and prevent food availability, decrease access to food and have an influence on food quality. Impacts on food supply will be very large because food shortage can contribute to global crisis and national security concerns. Because all the information supplied in this article
