Are twisters going to end

Answer 1

Eventually, yes, but not for hundreds of millions of years. The sun is gradually getting hotter. In 800 million to 1 billion years this will cause the ocean to evaporate, rendering Earth uninhabitable. The increase in temperature and the absence of the oceans will release carbon dioxide from carbonate rocks. This will lead to a runaway greenhouse effect, creating an atmosphere not unlike that of Venus, which is not supportive of tornadoes.
