Over the past few years, people have been warned by bunches of scientists that climate change is ruining the planet.
They've warned that ocean temperatures are warming or rising, weather events are becoming more severe, more regular and more damaging, and that we're observing changes not seen in centuries.
But now a new report has been released, by Aussie scientists, that says at the rate we're going, climate change 'threatens the premature extinction of Earth - originating intelligent life or the permanent and drastic destruction of its potential for desirable future development'.
No one likes to be alarmist but that's pretty damning.
This dystopian view of the future would hit around mid century, aka about 2050, if we keep going the way we're going.
The report, published by Melbourne think-tank Breakthrough National Centre for Climate Restoration, warns that ecosystems around the world, from the Arctic to the Amazon, will be accelerated by a rise in the global average temperature.
"Even for 2°C of warming, more than a billion people may need to be relocated and in high-end scenarios, the scale of destruction is beyond our capacity to model with a high likelihood of human civilization coming to an end," the report says.
Former chief of Australia's military Admiral Chris Barrie has backed the document, saying that human induced climate change is the number one threat to human life on Earth after nuclear war.
"Today's 7.5 billion human beings are already the most predatory species that ever existed, yet the global population has yet to peak and may reach 10 billion people, with dire implications absent a fundamental change in human behaviour," Admiral Barrie writes for the report.
Professor Will Steffen adds: "It's not a technological or a scientific problem, it's a question of humanities' socio-political values...We need a social tipping point that flips our thinking before we reach a tipping point in the climate system."
The report authors recognise that it's difficult to accurately predict what is going to happen in the next three decades because the data falls 'outside the human experience of the last thousand years'.
Kind of hard to map something out when you've got no reference point.
The document adds that by mid-century, Earth will likely reach and go past the 'point of no-return' and we're all essentially fucked then.
In order to avoid this, we need to start acting in the same way parts of the world mobilised for World War II.
