Of course we humans won’t have to worry about any of these space evolution events to finish us off. We will do it to ourselves in, if not within the next two or three years, it will surely come to pass in the next hundred years. The univrsal law of probability balance is inescapable. Just as stars are born and die and human are born and die, humanity in total will soon come crashing to an end.

In reality global warming is the least of humankind's problems. It will take hundreds of years for that to completely do in the human race, but not our nukes. We can never know from day to day what technical glitch or madman will trigger a massive launch of these doomsday weapons of mass destruction. So far by the thinest of margins our luck has held out, but the odds against continued good luck is turning against us hour by our, backed by the law of probability balance.
