I don't think there is any one plan. There are a number of things being done, not enough though.
There are plenty of things people do as individuals, but as a global issue there seems do be a divide on whether it is real or not.
3rd world countries cannot afford to make many of the improvements to their infrastructure without help/money from other nations. The practices of slash and burn agriculture is how many people live in these nations, I would guess a large portion of the world has no idea about global warming.
Another thing to consider is what will happen to Europe when the gulf steam stops. Some models show that happening as more ice melts and salinity and temperature levels get out of wack. Not only will that cause Europe to get colder, it will also probably be disastrous to our N Atlantic fisheries. Just something else to think about.
We have a mess on our hands with no clear cut solutions.
