One of the most frequent questions I encounter, whether serious or not, is about driving an EV in the rain, or through a carwash. Of course, EVs are well built, and the normal expectation of driving is that they encounter wet weather all the time. Of what use would windscreen wipers be otherwise?
I agree with Vincent Gray (NZ Skeptic 107), it is not possible to determine an average temperature for the Earth. However it is important to note that even the alarmists agree that the Earth is not warming and has not done so for about 17 years. The British Met Office even predicts it is not going to do so in the near future.
Zheng He is not a name that is well known in the west. However, his seven voyages from China, through the Indian Ocean to Africa between 1405 and 1435 would place him among the world's great explorers. Yet retired submarine captain Gavin Menzies is convinced Zheng He's feats were even greater. He believes a massive Chinese fleet conducted four simultaneous circumnavigations of the world between 1421 and 1423, during which they discovered the Americas, Australia, New Zealand, even Antarctica. But while they were away, the Chinese emperor turned his back on the outside world and, when the ships returned, had all mention of them erased. Why the records of Zheng He's other expeditions were kept, Menzies does not explain.
