GetUp! is organising the national day and Armidale residents will be asked to lend support to the campaign.

Organiser Colin Hargreaves said the day was meant to be fun and not aimed at riling anyone’s political beliefs.

“It’s a gathering to express the level of public concern to the government, to make them realise the people want them to do something regardless of the last election’s result,” he said.

The day will feature activities for children including face painting and Splat the CO2 molecule as opposed to Splat the Rat.

Northern Tablelands MP Adam Marshall, University of New England academic Annette Cowie and Patrick Nunn, who contributed to the Intergovernmental Panel on Climate Change’s fifth report, will all talk at the event. 

Mr Hargreaves said when talking about climate change it was important to remember rising temperatures meant higher minimum as well as maximum temperatures.

“When you say to someone that the temp has changed by 0.8 of a degree in the last 100 years they say ‘so what?’” he said. 

“Then you look at the number of records for highest temperatures that are being broken… it’s really quite extraordinary.” 

The event will run from 1pm with organisers encouraging people to wear orange and summer clothes, Mr Hargreaves said.
