By increasing our understanding and predictability of three large-scale climate drivers - El Nino (the Southern Oscillation), changes in the Indian Ocean sea surface temperatures and the Southern Annular mode (hemispheric changes in windiness and storm activity over the Southern Ocean and Antarctica) - researchers now have a better understanding of their influence on rainfall variability in the region.
Producers, agribusiness advisors, researchers and natural resource managers in the drought-stricken dryland grains and mixed farming regions of Victoria, South Australia and Western Australia are working together to respond to a drier and more variable climate.
Representatives from the Bureau of Meteorology, the Bureau of Rural Sciences, Meat & Livestock Australia, the Birchip Cropping Group and Managing Climate Variability have teamed up with local producers and (more)...
With climate change predictions pointing to Australia’s climate becoming even more variable, farmers are looking for more accurate seasonal forecasts that can be interpreted to help them better make decisions about planting, sowing, harvesting and stockin
Predicted changes in climate will affect the spread and competitiveness of pest animals and weeds in Australia. For example, in southern Australia, we can expect to see:
more very hot days (in excess of 35°C)
less incidence of frost
less winter rainfall across all southern regions; spring rainfall is expected to be
lower in south-eastern Australia, and autumn rainfall is more likely to be lower in the south-west of (more)...
The climate of the Earth is changing; it always has and always will.
At very long time scales, natural drivers of climate change include subtle shifts and wobbles in the Earth’s orbit. These shifts account for the ice ages and warm interglacial periods over the last million years. At decadal time scales, natural climate drivers include variations in ocean currents and solar output. At the annual scale, drivers such as volcanic eruptions (which cool the earth by adding reflective (more)...
