Dear Chris,
As you know, the Shenzhou XIII manned spacecraft successfully returned to the earth on 16th April, carrying three Chinese astronauts who had worked inside the Tiangong space station for six months.

9 . Temperatures around the North Pole have greatly increased in the last 50 years — changing a long-term natural cooling trend. Now the Arctic is warmer than at any time during the last 2000 years, according to a major new study.
The study, based on an analysis of tree rings and other things, provides compelling evidence that greenhouse gases released since the start of the industrial revolution are causing global warming.
An author, Darrel Kaufman said, “Scientists have known for a while that the current period of warming was coming after a long-term cooling trend. But our reconstruction quantifies the cooling with greater certainty than before.”
The research — published in the journal Science — comes from a team of British and American scientists who followed summer Arctic temperatures to the time of the Romans by studying natural signals in the landscape. Their reconstruction found that the Arctic got cooler in the summer months between 1 AD and 1900, thanks to a natural “wobble” (摇摆) in the Earth’s orbit around the Sun.
The wobble slowly increased the distance between the Earth and the Sun during the Arctic summer, reducing the summer temperatures by around 0.2 degree every thousand years and causing the “Little Ice Age” that led to freezing winters in the 17th, 18th and 19th centuries.
But during the 20th century, temperatures began to rise greatly — though the amount of sunlight reaching the Arctic during the summer was continuing to fall. The decade between 1999 to 2008 was the warmest in the last 2000 years, the research found. The research has shown that Arctic temperatures rose three times faster during the 20th century than the rest of the Northern Hemisphere.
Some researchers have predicted that the Arctic could be free from sea ice in the winter within the next few decades if the temperatures continue to rise.
