The earth is most suitable for human survival in the temperate zone, but due to the influence of ocean currents and altitude, it is more reasonable to use isotherm to divide. Here we mainly analyze the 0-20℃ which is most suitable for human survival. Countries with isotherms. Among them, it is roughly divided into 0-10℃ and 10-20℃. Of course, the 10-20℃ isotherm is the most suitable for human survival.
Here the isotherm is the average temperature throughout the year, which averages the four seasons. Can you imagine how hot summer will be if the average temperature is 25°C throughout the year? Southeast Asia, India is located in the 20-30 ℃ isotherm area.
We choose Europe as the standard. Why choose Europe as the standard? First, Europe is large enough, and the rich elements are appropriate as a scale. Second, although Europe barely joins the European Union, it is difficult to eliminate the internal causes of division and it is difficult to form a strong synergy. Self-protection is still reluctant, unlike the United States. BUFF blessing, Europe is still appropriate as a benchmark scale. The third is that all land in Europe is within the 0-20 ℃ isotherm range.
First look at Europe and use it as the standard (including the United Kingdom). The isotherm 0-10 ℃ and 10-20 ℃ occupies about half of the land, the population of 667 million in 2020, GDP 17.9 trillion US dollars, which is 2.68 trillion US dollars / 100 million people.
First compare the Sino-US .
United States . About 25% of the land is at 0-10℃, 58% at 10-20℃,17% are located in areas above 20°C. In 2020, the population is 330 million, and the GDP is 20.9 trillion US dollars, which is 6.33 trillion US dollars per 100 million population. Compared with the European standard line, the land climate of the United States is similar to that of Europe, but the population is reduced by half. If there is no BUFF bonus and early accumulation, it will not be so high. With the land climate endowment of the United States, the United States will lose the hegemonic BUFF bonus in the future, and its proportion of global GDP will only become lower and lower, and it will eventually be about 70% of the total European GDP. In the future, it will be converted into this year's standard calculation, about 3.8 trillion US dollars/100 million people, and GDP 12.54 trillion US dollars.
China . About 70% of the country's land is located at 0-10°C isotherm, 24% is located at 10-20°C, and 6% is located in areas above 20°C. In 2020, the population is 1.42 billion, and the GDP is US$14.7 trillion, or US$1.03 trillion per 100 million population. Compared with the European standard line, China's land climate endowment is a bit worse, and the average per capita in the future should be around 70% to 80% in Europe. According to the high calculation, the future will be converted into this year's standard calculation, about 2.14 trillion US dollars / 100 million people, GDP 30.38 trillion US dollars, if you add the "Global Leading Country" BUFF bonus coefficient, about 1.5, the future will be calculated according to this year's standard. GDP is 45.57 trillion U.S. dollars, about half of the total global GDP.
Let’s look at the surrounding areas of China .
Japan . Approximately 35% of the land is located at 0-10°C, and 65% is located at 0-20°C. In 2020, the population is 124.7 million, and the GDP is 4.81 trillion U.S. dollars, or 3.85 trillion U.S. dollars per 100 million population. According to European standards, Japan is doing well.However, its future development will become more and more difficult.
Korea . About 20% of the land is located at 0-10°C and 80% is located at 10-20°C. The population is 51.8 million, and the GDP is 1.63 trillion US dollars, or 3.12 trillion US dollars per 100 million population. The land has a very good climate endowment, and according to European standards, its economic development is still good.
Take a look at America’s main partners .
United Kingdom . Most of the land is located at 0-10°C isotherm. The population is 67 million, and the GDP is 2.7 trillion US dollars, or 4.02 trillion US dollars per 100 million population.
Canada . Approximately 15% of the country's land is located at 0-10°C on the isotherm, and the rest are located below 0°C. Most of the population is also located in this 15% land area. In 2020, the population is 38 million, and the GDP is 1.64 trillion US dollars, or 43,100 US dollars per 100 million population. Development is very good.
Australia . The land only faces the Antarctic. About 15% of the land near the sea is at the isotherm of 10-20℃, and the rest of the land is at the isotherm of 20-30℃. Melbourne, Sydney, Canberra ,Adelaide, Australia's major cities and population are crowded in this most livable 10-20 ℃ isotherm, this narrow range like a long belt. In 2020, the population is 255.6 million, and the GDP is 1.33 trillion US dollars, which is 5.19 trillion US dollars per 100 million population. Australia's arrogant economy is one of the reasons.
Generally speaking, the major US partners have achieved good economic results. It has benefited greatly from the proliferation of American economic exchanges.
Take a look at the BRIC countries .
Brazil . Only about 20% of the land is located in the isotherm of 10-20℃, including Sao Paulo, Rio de Janeiro , and other areas are greater than the 20℃ isotherm. The population is 210 million people, and the GDP is 1.44 trillion US dollars, or 0.68 trillion US dollars per 100 million population. The economic achievement is worse than that of Argentina.
South Africa . Only about 20% of the country’s land is located at the isotherm of 10-20°C, including Cape Town, and other areas are greater than the 20°C isotherm. The population is 58 million, and the GDP is 0.30 trillion U.S. dollars, or 0.51 trillion U.S. dollars per 100 million population.
Russia . About 17% of the country’s land is located at the 0-10°C isotherm, mainly located in a small part near Europe.And close to a small part of Northeast China, the rest of the area is below 0℃. The population is 146 million, and the GDP is 1.48 trillion US dollars, or 1.01 trillion US dollars per 100 million population. Relative to its neighbors, its economic achievements are not so good, but its territory is vast, close to the Arctic, Europe, and East Asia, with abundant strategic options and great potential for future development. The obvious limiting factor is that Russia has only one ice-free seaport, which is still located in the Arctic Circle.
India. Most of the country is located in areas above 30°C of the isotherm, so no analysis will be made.
Generally speaking, the other countries of the BRICS have little land and climate advantages, and only a small part of the land has a suitable climate.
A country with great potential in terms of land and climate.
The northern part of the Arabian Peninsula, the Black Sea, and the southern part of the Caspian Sea are all located at the isotherm of 10-20°C. The countries include Turkey, Iran, Iraq, and Syria. In ancient times, this large area was a land of fertile aquatic plants and once bred brilliant civilizations. Although they were all in the 10-20 ℃ isotherm region, their climate advantages were reduced compared to ancient times. Many, some areas have become desertified and desertification is serious, such as parts of Iraq.
Turkey . Most of the land is located at 10-20°C isotherm. In 2020, the population is 83 million, the GDP is 0.72 trillion US dollars, or 0.86 trillion US dollars per 100 million people, plus it is located in the world's transportation hub, and there is great potential for future development.
Iran,Iraq, Syria , most of these countries are located at the isotherm of 10-20 ℃, their territorial climate endowments are excellent, but wars and sanctions have made these three countries faltering. The three countries have strong national characters and have a long history. The history of civilization is difficult to tame. In the long run, the development potential of the three countries is unlimited, and the future can be expected.
South America has 2 countries with very good climate endowments.
Argentina . Most of the land is located at 10-20°C isotherm. The population is 45 million, and the GDP is 38 million U.S. dollars, or 0.84 trillion U.S. dollars per 100 million population. Argentina's geographical conditions are very good, but its economic achievements are not very good. It is a pity that it has great potential for future development.
Chile . Most of the land is located at 10-20°C isotherm. The population is 18 million, the GDP is 25 million U.S. dollars, or 1.39 trillion U.S. dollars per 100 million population, and its economic achievements are average, but it is much better than that of Argentina.
