Katoomba's Nigel Bell has been invited to join former US Vice President Al Gore and train in his Climate Reality Project.
The local architect has been active on built-environment, sustainability and community matters across the Mountains for decades including, most recently, bushfire recovery.
"We can't keep ignoring the evidence that the world's weather is warming. Climate change is too important to leave it to the politicians, we all need to know about and adapt for different futures," said Mr Bell.
"With better understanding we can prepare and act, household by household, street by street. We need to be pro-active and adjust, rather than just wait and ignore."
The Climate Reality Project is Al Gore's international climate change leadership program, in partnership with the Australian Conservation Foundation. It aims to educate the public about the harmful effects of global warming and to work towards solutions at the grass roots, world-wide.
Locally, LizsBastian has been an active ambassador in recent years, along with Climate Action and Transition Blue Mountains.
Climate Reality Project CEO Ken Berlin said: "We have taken these trainings around the world, and in every community committed leaders are standing up to take action on the climate change reality. Our goal is to provide them with the best possible tools to become even more effective leaders in their schools, businesses, churches, local and national governments."
Mr Bell expressed his excitement about the opportunity to present the latest climate reality information across the Mountains in a non-partisan way, to encourage people to make up their own minds and plan ahead.
"Changes are happening whether we're ready or not. This training provides me with positive tools I can share with audiences across the Mountains. I'm available to meet with any group or organisation that's interested. We all want a better future for ourselves and our kids, so let's make it happen."
