Despite an urgent cry from the Intergovernmental Panel on Climate Change, world leaders expected to attend this month’s G20 meeting in Brisbane, Australia, will not be considering global warming as a distinct agenda item. This year marks the first time in the past eight years that the gathering of G20 leaders will not address climate change as a stand-alone issue.

Austrialia Prime Minister Tony Abbott sees climate change outside of the scope of the G20, which he views as “an economic forum.” While in office, Abbott has repealed his country’s carbon tax, shut down its climate watchdog entity, and set the stage for growth of the coal industry.

The G20 omission did not go unnoticed. A coalition of environmental groups launched an appeal on Monday designed to prompt G20 leaders to recognize the looming threat of manmade climate change and put it back on the meeting agenda. The campaign is authored by 1 million women, Australian Youth Climate Coalition, Australian Conservation Foundation, Earth Hour, GetUp, Greenpeace, Oxfam, 350.org, and WWF.

People are urged to tweet G20 leaders using #onmyagenda in their efforts to persuade the members to reconsider the climate issue.

“There is no solution to climate change without G20 members on board,” WWF CEO Dermot O’Gorman said in a statement. “These countries are responsible for around 80% of global emissions and more than 80% of global economic activity.”

“Young people do not have a seat around the negotiating table, but will live to feel the consequences of world leaders’ decisions,” adds Lucy Manne, Co-Director of the Australian Youth Climate Coalition. “It is the responsibility of the G20 to put it on their agenda.”

A billboard that the campaign placed at the Brisbane Airport to greet meeting attendees with a reminder of the impact of higher than normal temperatures on the nation’s farmers was banned by the airport authority for being “too political.”

The coalition is urging concerned individuals to learn how they can help at onmyagenda.org.
