I'm hugely pessimistic, but I haven't given up. Everyone frustrated by lack of action is another potential protester locking themselves up in front of a fracking plant or daubing graffiti and disabling a pump at a petrol station. Realistically I don't think there will be much real or adequate government action until the system we have is creaking at the seams. Dealing with migration from poorer parts of the world, dealing with the cost and chaos of weather events like floods and storms. Some actually buying land 500 ft above sea level, away from population centres. Governments having to choose between martial law or reelection will change views on global throwaway consumerism surprisingly quickly. I also expect to see a rebirth in spending on navies, troops and border guards amongst the developed nations. Nonetheless there comes a point (as yet unknown) where it becomes a choice of fix it or watch Rome burn. It might even reach a last minute point where it's clearly cheaper to fix it than keep ignoring it. By that time costs could easily be an order of magnitude higher, and far more dependent on geo engineering that might generate its own unforeseen problems. But every tiny act from individuals might, just might, contribute to a tipping point before it gets that far.
