Did the enormous West Antarctic Ice Sheet collapse the last time global temperatures were 1.5°C above preindustrial levels? The answer lay in the DNA of an octopus.
With a record hot summer expected, will rooftop solar cover our need to be cool?

Australia supported a phase-out of fossil fuels at the recent UN climate summit but is still expanding coal and gas production. It’s a contradiction that threatens the planet. There is a better way.
Pine grows faster and sequesters more carbon. But native forest is better for biodiversity in the long run. Transitioning between the two offers a win-win solution.
Once the immediate crisis in North Queensland has subsided, authorities will need to grapple with how to deal with the ‘new normal’ of extreme weather events. The big question is: are they prepared?
