Have you done a critical review of this video and Salby’s new one from London in July 2016? I believe this is the most important refutation of the CO2 catastrophe hypothesis but have found only limited in depth review of his talks. The reviewers I trust have good things to say for him and no real problems with his methods or results. SkS have multiple comments that even I can see are erroneous. I would appreciate your or some other qualified persons critique .

Raw deal for Greenhouse Gasses
I ask people – greenhouse gasses are bad for you, RIGHT? Most people when askes say yes. Next question – what is the most abundant greenhouse gas? Every time I get CO2. Water vapour or clouds is the right answer. Water vapour is the most significant greenhouse gas source and is responsible for roughly 96% of all greenhouse gasses. Without our greenhouse gasses we would be like the Moon. Greenhouse gasses keep us warm and protect us from dangerous x-rays, gamma rays, solar flares and solar winds. This is well known among climatologists and is common knowledge, but among special interests, certain governmental groups, and news reporters this is under-emphasized or just ignored altogether.
CO2 is under 1% of all natural and manmade greenhouse gasses in the atmosphere. Of that one percent manmade CO2 makes up roughly four one hundredths of a percent. Half of the CO2 that comes from natural sources like volcanos or decay goes into the ocean and feeds the plankton to make half of our oxygen, and most of the rest feeds all the plants in the world with the help of photosynthesis that also gives us our oxygen. CO2 is good for life and at 400 parts per million is at one of its lowest levels in global history. Early man breathed 3000 parts per million and people that go down in submarines breath 8000 parts per million or more and they have their hand on the nuclear button.
This is only a small part of the complex climate science issue and as a duel citizen I voted for Trudeau – Hillary Clinton and do not watch Fox news.
