This campaign demands that 'world leaders' tell us what plans they have developed to tackle the problem, what concrete targets (e.g., atmospheric CO2 levels and temperatures) they are aiming for, when they expect to achieve them, what measures are being taken to stimulate appropriate technologies and what difficulties they expect along the way.
Why is this important?
I, and my children, are rather averse to choking on the effluent of 'big business': there will be NO big business if we all choke or end up massacred in 'emissions' trade wars!
