I first became seriously aware of climate change around 1995. One branch of my family were then farmers (outside the UK) and they said that the reduced rainfall and other changes was unlike anything that they had seen in 40 years. As I read more I cam to the conclusion that: The chances of the countries of the world getting their collective act together - in time - to prevent major climate change = Zero.
In the subsequent 27+ years, I have seen nothing to make me change my mind. Yes, inroads are being made but they will not be enough.
