Venue: Seminar Room, Lab14, 290
Presenters: Dr Karl Braganza
The Australian Bureau of Meteorology and CSIRO have released their fourth biennial State of the Climate Report, which provides an update on the climate changes and long-term trends in Australia’s climate.
Dr Karl Braganza will discuss the key findings from the report, which include:
• Australia’s climate has warmed in both mean surface air temperature and surrounding sea surface temperature by around 1°C since 1910.
• The duration, frequency and intensity of extreme heat events have increased across large parts of Australia.
• There has been an increase in extreme fire weather, and a longer fire season, across large parts of Australia since the 1970s.
• May-July rainfall has reduced by around 19 per cent since 1970 in the southwest of Australia.
• There has been a decline of around 11 per cent since the mid-1990s in the April-October growing season rainfall in the continental southeast.
• Rainfall has increased across parts of northern Australia since the 1970s.
• Oceans around Australia have warmed and ocean acidity levels have increased.
• Sea levels have risen around Australia. The rise in mean sea level amplifies the effects of high tides and storm surges.
Dr Karl Braganza is the Manager of Climate Monitoring at the Australian Bureau of Meteorology.
