Climate change has put the Great Barrier Reef into dire trouble, raising water temperatures and causing its worst bleaching event in recorded history. Researchers have warned that now is the last chance to step in and give it a fighting chance.
Meanwhile, Australia is drying out, and world heritage forests in Tasmania have burnt for the first time ever.
We’d like to see the environmental impacts of climate change where you are – your pictures, your videos and your words.
Do you live near the reef or another area of natural beauty that is being threatened? Perhaps you work in conservation or spend leisure time exploring the country. Have you witnessed unusual events that seem to be related to climate change?
