When the government closed Japan’s doors to the West, it ordered most Europeans to leave the country.

It is referred as the Sakoku policy and it was a reaction to the unequal trade treaties forced upon them by the Commodore Perry and its ships.

The Korea and China answers cannot be valid, since they are not part of the "West", being Asian countries as well, plus trade with China was important during that Sakoku policy.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
