This particular video is valid, verifiable, and the speaker is even offering direct open communication. Most if not all other online climate change activists are not. In fact if you challenge any of them to a discussion of facts, they quickly and abruptly walk away. I am not saying that this video is the final proof I am looking for, but, to dismiss it as hyperbole would be foolish.
Just in case this website goes offline for any reason, or if Google deletes the video for any reason, I have uploaded it to my server so it cannot be deleted. Also, I do NOT use any cloud services as they can be easily hacked. I back up everything on a personal hard drive. I do not trust anything cloud based.
