Australia is experiencing widespread, rapid climate change not seen for thousands of years and may warm by 4℃ or more this century, according to a highly anticipated report by the Intergovernmental Panel on Climate Change (IPCC).

Earth has warmed 1.09℃ since pre-industrial times and many changes such as sea-level rise and glacier melt are now virtually irreversible, according to the most sobering report yet by the Intergovernmental Panel on Climate Change (IPCC).

The much-awaited new report from the Intergovernmental Panel on Climate Change (IPCC) is due later today. Ahead of the release, debate has erupted about the computer models at the very heart of global climate projections.

Until recently it was thought neutron star mergers were the only way heavy elements (heavier than Zinc) could be produced. These mergers involve the mashup of the remnants of two massive stars in a binary system.

Australia has the world’s worst track record for wiping out mammals, with 34 species declared extinct since European colonisation. But today, we bring some good news: one rodent species, Gould’s mouse (Pseudomys gouldii), is set to be crossed off Australia’s extinct species list.

The LIGO gravitational wave observatory in the United States is so sensitive to vibrations it can detect the tiny ripples in space-time called gravitational waves.

One cold winter doesn't negate more than a century of global warming. We need the political leadership to set the world on a safer path. Ill-informed tweets by government senators won't help.

Internal waves can create pretty cloud shapes in the sky, as well as making life unpleasant for passengers on aeroplanes. And in the oceans they can be a deadly hazard to submarines.

Our team of 28 scientists identified the top 26 Australian butterfly species and subspecies at greatest risk of extinction. We also estimated the probability that they will be lost within 20-years.
