Contributions to sea‑level rise have increased by half since 1993, largely because of Greenland’s ice

Greenland’s ice is largely responsible for the accelerating pace of sea-level rise. A new analysis shows that, while Greenland accounted for just 5% of the rise in 1993, that figure rose to 25% by 2014.

CSIRO must ensure climate science is maintained

A proposal for the Bureau of Meteorology to take on CSIRO climate scientists is a good idea - but CSIRO needs to make sure nothing is lost.

What does the science really say about sea‑level rise?

Could sea levels really rise by several metres this century. Probably not, although this century’s greenhouse emissions could potentially set the stage for large rises in centuries to come.

Ocean depths heating steadily despite global warming ‘pause’

The oceans are continuing to warm steadily despite an apparent slowdown in global warming at the earth’s surface, according to data collected by thousands of floating robots published today in Nature Climate…

IPCC’s ‘most important report’ sets stage for Paris climate talks

Members of the Intergovernmental Panel on Climate Change (IPCC) say they are confident their latest report, released in Copenhagen today, will help give politicians the impetus to commit to the deep emissions…

15 years from now, our impact on regional sea level will be clear

Human activity is driving sea levels higher. Australia’s seas are likely to rise by around 70 centimetres by 2100 if nothing is done to combat climate change. But 2100 can seem a long way off. At the moment…

Scrapping sea level protection puts Australian homes at risk

As the science on the coastal impacts of climate change gets stronger, the protections for Australia’s coastal communities are getting weaker. If that continues, everyone will pay. Along the eastern seaboard…

Solar forcing effect on climate change ‘extremely small’: IPCC scientist

Changes in solar radiation, known as solar forcing, have had only a very small effect on climate change, a member of the UN’s top panel of climate scientists said today. The comment, made by a member of…

Improving sea‑level projections

Satellite and in situ observations show sea level is continuing to rise. In the last Intergovernmental Panel on Climate Change report, earth system model projections indicated global sea-level rise by…
