I don't think we can over emphasise the importance of changing everyone's mindset to help combat climate change. As SRS says there are many factors in play here. Maybe there are some we can do nothing about. Maybe, as Donuel says, something as yet unknown will play a part. Although I must point out that this could be bad or good! But none of this should stop us from changing what we can change for the better. Little steps are all it takes to get things rolling. Stop using plastic bags and switch off unused lights today. Get ready for bigger changes to come!
