Al Gore in Melbourne for climate summit

al gore

"Alternative facts won't halt rising temperatures and fake news won't make polluted air safe to breathe."

That's the motto of former US vice president Al Gore's climate change organisation, which says it's time for climate change deniers to face the facts about the "planetary emergency" facing humanity.

Mr Gore will be in Melbourne on Thursday, presenting a session at the Ecocity World Summit titled: The Case for Optimism on the Climate Crisis.

Renewable energy will be high on the list of topics he will discuss at the summit, saying earlier this week that he hoped Australia would put shifting to renewable energy "at the top of the list".

Mr Gore said given the availability of solar, wind and batteries as renewable energy sources, and their dramatic fall in cost, it makes economic sense for countries to switch from heavy-polluting fossil fuels.

"Those countries that take a leadership role will benefit most from the new jobs that are being created," Mr Gore said earlier this week.

"The fastest-growing jobs in the world are in renewable energy. In my country solar jobs are growing 17 times faster than other jobs in the economy."

China, India and Australia were among 19 world powers at last weekend's G20 meeting in Hamburg that reaffirmed support for the Paris climate agreement after US President Donald Trump pulled out of the deal.

Mr Gore was pleased to see the group holding firm on the 2015 agreement signed by 196 nations that pledged to reduce carbon emissions.

"Of course it would be so much better if the president of the United States would help to lead the world instead of being off isolated in the corner by himself," he said.

"But the rest of the world gets it, the rest of the world is moving forward."

Mr Gore is in Australia ahead of the release of An Inconvenient Sequel, the follow up to his Oscar-winning 2006 documentary on global warming, and he will address the Melbourne summit at 9.30am on Thursday.
