Blab, Blab, Blab.  There is little action on climate change simply because there are very few actions that could make a significant difference.  The BS on gradual threats is just that.  We took lead out of gas which offered a gradual poisoning effect.  We got rid of DDT which did not produce instant threat.  We do many things that have benefit over the long haul.  The reason we have done little on climate change is simply because there is nothing we can realistically do that will stop the build-up of CO2.  Maybe slow it a bit, but not dramatically and certainly not stop it.  With 7 billion humans, there is just no real way to prevent change to the planet supporting us.
