The Government Accountability Office, a federal agency widely known as a group of black-helicopter chasing conspiracy theorists (joke); has produced a report that also pretty much says we don't have to worry about Global Warming.
You know why? Peak and decline in oil production is upon us. According to this GAO research, the phenomenon is both real and pretty soon. It will be accompanied by substantial economic displacement etc.
So less oil will be consumed as gas prices top $10/gallon and keep climbing.
This will also raise prices of alternatives; so we can pretty much expect energy costs to be the most substantial portion of the cost of most items, especially foods that are typically trucked.
As more and more money goes into absolute bare necessities; less will be available for non-necessities. Less oil will be consumed, etc.
According to some experts, millions if not billions of people will die from starvation. This will also shrink humanity's carbon footprint.
Governments, especially less stable ones, will likely be displaced thus saving us from the hot air of politicians.
So don't worry. We're gonna run out of cheap oil.
