Group of 20 host Tony Abbott went to great lengths to keep one topic -- climate change -- off the agenda at this weekend's confab in Brisbane. There's little mystery why: While the world hails China and the U.S. for moving forward on curbing carbon emissions, Australia is backsliding by scrapping a tax on carbon and resisting pressure to expand the use of renewables.
Abbott's justification? The need for growth. In fact, Australia's prime minister wants the rest of the G-20 also to pledge to grow by an additional 2 percent or more over five years.
