Earth has experienced cold periods (informally referred to as “ice ages,” or "glacials") and warm periods (“interglacials”) on roughly 100,000-year cycles for at least the last 1 million years. The last of these ice age glaciations peaked* around 20,000 years ago.

some transcript from vid:

In 1966 a well-known engineer released a book with information that could impact everyone on earth. But before anyone could read it, it was classified by the CIA.

We only learned of its existence a few years ago because of a Freedom of Information request.

The CIA only released 57 pages of the original 284-page manuscript. And those pages have been, in the CIA's own words, "sanitized".

Why does the CIA think this book is so dangerous that they had to hide it from the public for 60 years; and continue to hide most of it?

It's because the man who wrote it describes the end of the world.
