Breitbart News Tonight - Patrick Moore - March 6, 2019 by Breitbart published on 2019-03-07T14:44:47Z www.breitbart.com/radio Genre News & Politics Comment by Kata List Productions Canadians like me prefer Patrick Moore over David Suzuki.. thanks for this 2020-06-26T19:57:16Z Comment by James Wood (Banamine) Add all of these up, and you get an estimate of around 645 million tons of CO2 per year. Yes, there are uncertainties; yes, there's annual variation; yes, it's easy to get led astray if you think that Mt. Etna is typical, rather than the unusually large emitter of CO2 that it is. When you realize that volcanism contributes 645 million tons of CO2 per year – and it becomes clearer if you write it as 0.645 billion tons of CO2 per year – compared to humanity's 29 billion tons per year, it's overwhelmingly clear what's caused the carbon dioxide increase in Earth's atmosphere since 1750. 2019-06-02T16:25:29Z
