Will the renewable energy transition end up creating yet more greenhouse emissions, as we ramp up the manufacture of wind turbines and solar cells? Not if their manufacture is itself powered by renewables.
Despite the climate crisis, humans have continued emitting and intensively using fossil fuels.
The climate crisis is a complex scientific problem. New systems have to be developed through democratic systemic reforms.
The increasingly bleached coral at Black Point on the Cobourg Peninsula is a worrying sign of what’s to come for other coral reefs in Australia.
Coral bleaching has struck the Northern Territory, adding urgency to the need for better national management strategies for our warming oceans.

But it's too early to tell whether climate change is to blame.
Paris “under water” and other European cities facing drastic climate change should trigger planners to think urban spaces differently.
In the future, Europe will suffer from more heat waves as well as extreme rainfall, presenting new challenges for planners and health care services. Building resilient cities can help.
Puerto Rico’s power utility, PREPA, has been decimated by years of scarcity and bad management. But will privatizing it really turn the lights back on for Puerto Ricans?
