There are so many myths surrounding the Murray River. It is far away from most Australians who live in cities and over the years various activists have told stories which have grabbed national headlines while bearing little relationship with reality. Then there is this general disconnect because people who live and work along the Murray, [...]

According to David Nason writing in last Friday’s The Australian, the traditional owners of the Lower Lakes, the Ngarrindjeri, want more water flowing through their country from up-river to maintain connectivity and keep the Murray’s mouth as the “Meeting of the Waters”. http://www.theaustralian.com.au/in-depth/aboriginal-australia/title-fight-looms-on-murray-water-flow/story-e6frgd9f-1226035619633?from=public_rss But no mention is made of the tens of thousands of megalitres [...]

For the last three autumns, Lake Eyre in central Australia has received runoff from good flooding rains. These photographs were taken by Rhyl as she flew from Quilpie to Birdsville to Lake Eyre in July 2010. And the flood waters are arriving again this year. Wild flowers as a mass of yellow from the air. [...]

ON November 10 last year the Australian government’s Multi-party Climate Change Committee (MCCC) received a scientific briefing before it entered the policy-setting mode that it remains in today. The briefing was provided by the only scientist on the Committee, Professor Will Steffen. A copy of the slide presentation that Steffen used has recently come into [...]

But now that those migration flows have failed to materialize, the UN has distanced itself from the forecasts. On the contrary, populations are growing [...]

At the right intensity, when light is traveling through a material that does not conduct electricity, the light field can generate magnetic effects that are 100 million times stronger than previously expected. This is the remarkable conclusion from work in applied physics at the University of Michigan. Quoting from their website: “A dramatic and surprising [...]

RADIATIVE transfer is an incredibly important topic when it comes to the earth’s climate system. It is the only way for the earth to either heat up, via absorption, or cool down, via emission.  The temperature of the earth is set by these two counter acting mechanisms. To solve this balance for the earth’s dynamic [...]
