In your opening statement, I highlighted your believe that ‘no-one knows,’ yet you mention and provide a link to what Freeman Dyson has to say in the respect of Global Warming and CO2.
Which one is it, no-one knows or Dyson does?
If you push the idea of one Freeman Dyson, who by many successful accounts, and your indication, is a preeminent Physicist. But, you also lack to mention that this Physicist has views that Nature will heel to Human’s intellect. That’s a very arrogant view of humanity.
However, you fail to mention that ‘On September 20, 2016, 376 members of the National Academy of Sciences, including 30 Nobel laureates, published an open letter to draw attention to the serious risks of climate change.’ in such letter Stephen Hawking, Cambridge University, and Jeremiah Ostriker, Columbia University, two preeminent Astro Physicists strongly assert Global Warming.
Lastly, are you a scientist? is your background, intellectually, pragmatically and educated enough to make statements against Global Warming? If so, please provide your credentials, and if not, please let’s guide our views by facts+figures of those that are very involved in understanding the science of it.
