Over the past 12 months, the federal government has approved multiple fossil fuel projects and cut climate science funding.

Global warming is set to surpass the 1.5°C limit if governments worldwide fail to act.
The world is likely to pass 1.5°C of warming. Africa faces worse heat, drought and floods, but faster cuts to emissions can still limit the overshoot damage.
It’s no longer possible to hold climate change to 1.5°C. But it’s not game over – it’s game on.
Even allowing warming to exceed 1.5°C for a few decades could trigger irreversible damage.
Investing in carbon removal, on top of the most ambitious emissions cuts possible, is a no-regrets strategy.
Surpassing 1.5°C of warming can be undone at a later date – using tech, land and resources that don’t exist.
The net zero approach of the Paris agreement has become detached from reality as it increasingly relies on science fiction levels of speculative technology.
A climate overshoot that creates warmer oceans with lower oxygen levels will reduce the suitable habitat for many marine species long after CO₂ levels have peaked and declined.
Holding climate change to 1.5 might be possible – but in the best case, we’ll blow past the limit first and then backpedal.
