Will the Four R's Save Humanity?

Sir David King is an eminent Cambridge chemist, who was also a former Chief Scientific Officer for the UK. He's now Chair of the Global Climate Crisis Advisory Group. King opines that 'survival of humanity is still within our grasp-just'. Nice to know? (https://www.theguardian.com/commentisfree/article/2024/may/27/humanity-survival-emissions-resilience-ecosystems-greenhouse-gases). King outlines the 'radical steps' needed to ensure survival of human society. They might be designated 'The Four R's'. Namely:- 1. Reducing emissions; 2. Removing excess 'greenhouse gases' already in the atmosphere; 3. Repairing ecosystems and 4. Resilience- strengthening local and global defences against inevitable climate impacts. King's 'prescription' is the kind of eminently-sensible list a Chemist might produce. The 'fly in the ointment', however, is human behaviour. All the indications, are that politicians and their publics are now generally becoming even further obsessed with 'economic growth'; migration and conflict (as opposed to cooperation), than was the case at the time of the Paris Accord. It's also going to require a completely different 'mindset', to maintain our currently 'human-friendly' planet. Instigating and fulfilling 'The Four R's' isn't going to be easy, with so many voices raised against action!
