CLIMATE change has made it into the G20 communique. Leaders agreed to "support strong and effective action to address climate change." Tony Abbott said Australia always believed that climate change is "real" and humanity contributes. He talked up his governments's Direct Action policy, recently passed in the Senate. So we aren't just talking about taking action against climate change. We are cracking on with the job. "We will be making further decisions at the right time," Mr Abbott said, when asked about when Australia will commit to new targets. Mr Abbott told reporters this year's summit has delivered "real, practical outcomes." People around the world will be "better off" because of the measures to boost growth and jobs, he said. RUSSIAN HOME: Vladimir Putin leaves early after G20 Summit Agreement ... US President Barak Obama, Prime Minister Tony Abbott and Japanese Prime Minister Shinzo Abe in a tri-lateral meeting on the second day of the G20 in Brisbane. Mr Abbott said "our actions will support sustainable development, economic growth and certainty for business and investment." All will also work "constructively" towards next year's climate change conference in Paris, he added. "It has been a weekend of achievement," the Prime Minister said. I believe that the G20 this weekend has shifted a gear from responding to events to setting an agenda for growth. Mr Abbott said he believed that the countries of the world and their people, "will be better off" because of this weekend in Brisbane. The Prime Minister said, with a smile, that he was happy to be "on a unity ticket" with Vladimir Putin. His answer was in response to a question from a Russian journalist who quoted the Russian President as saying Mr Abbott was a "good partner." Making his point ...

"When all is said and done, President Putin was a guest in our country," he said. President Putin is a member of the G20 and I was happy to treat him with respect and courtesy while he was here in Australia. But Mr Abbott said he understood there had been "pretty robust" discussions between the Russian President and other leaders at the conference. Mr Abbott said "obviously" he has some differences with the Russian government. I don't particularly approve, in fact I utterly deplore what seems to be happening in Eastern Ukraine. Host ...

So these are clearly on the record and I had a very robust discussion about MH17 with President Putin. When asked about his interactions with President Putin, US President Barack Obama said they were "businesslike and blunt." If he continues down the path that he is on, violating international law, providing heavy arms to the separatists in Ukraine ... then the isolation that Russia is currently experiencing will continue. The G20 summit was not just a "good old chin wag," Mr Obama said. It was a productive summit. Originally published as Leaders to fight climate change
