Welcome to 2020, but first an area average review of Australia for 2019 in 22 tweets, mostly from the @BOM_au, providing a year snapshot of #climatechange indicators.
1. In 2019 Annual mean temperature anomaly reached a new high of +1.5C based on a 1961-1990 climatology baseline
1. In 2019 Annual mean temperature anomaly reached a new high of +1.5C based on a 1961-1990 climatology baseline
2. Mean Temperature anomaly for Australia for 2019
3. Maximum temperature decile for Australia for 2019
4. Minumum Temperature decile for Australia for 2019
5. In 2019 Australia set a new record for a negative rainfall anomaly, almost 200mm below the average in a data record spanning from 1900, despite a long term trend for a slight increase in rainfall.
6. Australian Rainfall deciles for 2019
7. Australian Rainfall percentages for 2019
8. Rainfall deficiencies (Drought) for Australia for 2019
9. Looking at Rainfall deficiencies (drought) for 36 months across 2017-2019 the Murray Darling Basin stands out prominently withSE Australia having substantially deficient rainfall

16. Seasonal Bushfire outlooks for August and December 2019. Note August Outlook above normal fire potential describes the conflagration from East Gippsland through NSW to Queensland that has ocurred. We still have the majority of the fire season ahead.
