No help needed, we are doing a good job all by ourselves.
People have been predicting the end of the world since there were people. Time and time again they have been proven wrong. It is not hard to go back and find endless overwrought predictions of doom from the 90s that are laughable today. Just like the predictions of doom being made today will be laughable in 30 years even as they are replaced by another set of dire predictions because "doom mongers gotta monger".
