Australia has warmed by approximately 1 °C since 1910

On 23 March 2012, World Meteorological Day, the Bureau officially released its updated and improved Australian temperature dataset.

Known as the Australian Climate Observations Reference Network – Surface Air Temperature (ACORN-SAT) the new dataset was developed to monitor and analyse long-term climate variability and change in Australia.

Twelve hundred flood warnings and watches, 2350 flood predictions and more than 6500 property evacuation orders: these are some of the staggering numbers from the widespread flooding in New South Wales since November 2011.

The 2011–12 La Niña ended in March, following the second successive summer in which La Niña contributed to significant rain and flooding across many parts of Australia.

The period from April 2010 to March 2012 was Australia’s wettest two-year period ever recorded. Despite its demise, ocean temperatures around parts of Australia remain very warm, and hence above-average rainfall is still forecast for some regions.

So with La Nina finished, what can we expect next?

The Great Barrier Reef is set to be seen in a new way. eReefs is an innovative project that will allow people to find information about why and how the Reef is changing and what could happen into the future.

eReefs is a collaborative project that will provide for the Reef information akin to that provided for weather. It will span the entire Reef from catchment to ocean, aid decision-making, and improve communication and reporting using pictures and maps.

eReefs will provide interactive information at scales and detail previously unavailable. It is a significant step in building comprehensive, national coastal information systems.

Geofabric webinar draws a crowd

More than 100 people from throughout Australia joined our inaugural Geofabric webinars recently.

Participants dialled in via computers and phones to see an onscreen presentation and demonstration, ask questions, submit comments and contribute to discussions.

The technology proved an excellent way for Bureau Geofabric experts, Elizabeth McDonald and Malcolm Parnell, to demonstrate how to download and set up Geofabric data in an ArcGIS environment. They showed participants how to calculate rainfall statistics for a specified catchment area, and responsed to questions throughout.

A recording of the webinar is freely available on our website. Access the Geofabric
