Australia must treble its emissions reduction targets and reach net-zero emissions by 2035. Without this and other radical global action, the chance to hold warming to well below 2°C will pass us by.
Scientists are learning trees can emit methane, which could be a big problem for global warming. But a world-first discovery of methane-eating bacteria in paperbark can help moderate this.
Climate change has already made tropical oceans too hot for some marine species to survive. As they flee towards the poles, the implications for ecosystems and human livelihoods will be profound.
This is not an imaginary future dystopia. It’s a scientific projection of Australia under 3°C of global warming – a future we must both strenuously try to avoid, but also prepare for.

We hear a lot about the Morrison government ‘kicking the can down the road’ on emissions reduction. New research reveals the precise burden that forces onto young Australians.
Growing weed indoors is not an environmentally friendly process. Climate controls create a lot of greenhouse gas emissions, and where the pot is produced has a huge influence on emission levels.
Groundwater was once thought to buffer streams from warming, but an inexpensive new technique shows streams fed by shallow groundwater may be just as susceptible as those without.
As our cities get hotter, rebuilding whole suburbs better suited to the heat is not an option. Instead, we can draw from the best examples of how to adapt neighbourhoods and behaviours.
The US is formally back in the Paris climate agreement as of today. As one of the world’s largest greenhouse gas emitters, it has a lot of work to do, with food security, health and safety at stake.
Several countries have made pledges to reduce their greenhouse gas emissions to zero by mid-century. But new research finds the remaining carbon budget will be depleted before we get there.
We think of mountains as remote and little affected by human activity. Unfortunately, the negative impacts of what we do has important implications for nature, wildlife and human society.
