What's your source of this data?
According to the following:
Transportation & Climate Change
In the United States, transportation accounts for 28% of the greenhouse gas emissions and aviation only accounts for 9% of that. Yes, the data source cites only US emissions, but maybe globally transportation is a smaller percentage because in many nations people are less likely to use motorized transport for passenger and goods movement. However, I seriously doubt that aviation would account for 20% of global greenhouse gas emissions.
On another matter, your points are undermined when you ridicule others as being "PC."
