I have been thinking about our changing climate a bit this morning and a thought occurred to me. This is purely hypothetical, but just suppose that we, as a human race, were to stop producing “greenhouse gases” completely, and after we did so, they planet kept warming indefinitely. How many years would it take for the scientists who have been blaming human activity for climate change, to accept that humans were not responsible?
I would be willing to say that it wouldn’t happen in my lifetime.
I think the next thirty to fifty years would be spent blaming “all those years of human activity” for the continuing increase in temperatures. The following fifty years or so would probably be spent trying to find something else which was “continuing” the increase, although scientists would start to realise the situation wasn’t caused by human towards the end of this period.
I think it would take a bit over 100 years for the majority of the “humans are responsible” brigade to change their tune, but even then there would be those who would insist that humans caused an “irreversible change”.
As I said, this is entirely hypothetical, but it is worth thinking about. What do you think would happen amongst the scientific community in this hypothetical scenario?
