What will the weather be like next week, next season, or by the end of the century? In the absence of a second Earth to use in an experiment, global weather and climate model simulations are the only tools we have to answer these questions.
Climate change and the loss of biodiversity are two of the greatest environmental issues of our time. Is it possible to address both of those problems at once?
It’s autumn – or so you may think. But did autumn really start on 1 March? And why do we observe four seasons, each exactly three months long?
Some climate models show that, under high greenhouse gas emissions, Sydney could be up to 4.8C hotter and have 20% less rainfall by 2090. Others show the Harbour City could warm only by 2.3C and become 25% wetter. How do we deal with such large uncertainty?
What will Australia look like in 2050? Even if we significantly reduce our greenhouse gas emissions as under an intermediate scenario, Melbourne’s annual average climate could look more like that of Adelaide’s, and Adelaide’s climate could be more like that of Griffith in New South Wales.
Paul Fraser looks at things that aren’t there, and at invisible things. He came up with the idea of having a library of air. But it’s not because he’s a bit odd – he’s not. He’s doing these things as part of some vitally important science.
A new investigation of satellite records reveals that the Earth is getting greener, despite ongoing deforestation in Indonesia and South America.
With three UNESCO World Heritage Areas under threat from climate change, including Australia’s Great Barrier Reef, scientists have put forward a new approach to making iconic ecosystems more resilient—and it’s not just about reducing global emissions.
