The Earth is burning. From California to Washington, from Amazon rain forest and Pantanal to Siberia. There is no doubt that the global warming is the cause. So, who's responsible for putting the world on fire?
tl;dr the rich. The rich are responsible for the great chunk of the CO2 emissions. One intercontinental flight emits more CO2 than majority of the people in the world can emit in a year. Someone who has to travel two hours to the work everyday because there is no job closer isn't to blame, too.
