1. Why is it so hot this summer? Although scientists have attributed one hot process to a specific 'atmospheric condition', it is certain that global climate change has caused regional atmospheric variability and adjustments that lead to extreme heat.
In 2020, the global average temperature is 1.2°C above pre-industrial levels. 2011 to 2020 is the warmest decade since 1850.
A team of researchers from a number of institutions, including Oxford University, pointed out in an analysis just last year that if global warming rises to 2°C in the next two decades or so, a heat wave that should have been a once-in-a-millennium event could occur every five to 10 years.

3. aircraft "wipers" can also be used to reduce noise. This is actually the front of the cockpit vortex generator, not only can reduce the drag caused by airflow, but also can reduce about 3 decibels of wind noise.
4. There is no i and o in common motor vehicle number plates. i and the number 1 are more alike, and o and the number 0 are also more similar, which is easily confused and difficult to manage. That's why there are no o and i in common motor vehicle number plates.
5. it turns out that doctoral studies and military service are counted as years of service!
6. Broke Sisters, The Big Bang Theory, and Old Friends are all filmed like plays performed live in front of an audience, so the laughter and applause in the background are recorded reactions of the audience in real time.

8. The sheep-eating tree is a carnivore in the plant world. The sheep-eating tree has razor-like flower spines, and once sheep are close to it, they are easily entangled in their fur and eventually starve to death because they cannot move, while the sheep-eating tree absorbs nutrients from decaying animal carcasses through the soil.

13. More than 5,000 years ago, the Arabian baboons were considered sacred by the ancient Egyptians as one of the incarnations of the god of wisdom and the moon god, Turb, as well as the prototypes of Babi, the judge of the underworld, and Hapi, the god of funerals. They were even mummified, thus demonstrating their special status.
However, the divine beasts do not have a good time. Many of the baboons that were mummified had their teeth removed during their lifetime, as well as rickets and bone deformities. The so-called "glory of the sacred animals" is accompanied by the loss of freedom and health in captivity in the temple.
14. Cats can transform humans into "slaves" by purring alone. When the average domestic cat wants to ask you to serve it, it will emit a moving high-frequency purr that evokes the human instinct to pamper.
